Midwife Licensure Exam Health Assessment — Systematic Head-to-Toe & Body-System AssessmentStudy Notes

A systematic head-to-toe assessment ensures no body region or system is overlooked. This approach is efficient, organized, and minimizes disruption to the patient's comfort and energy reserves—especially important in the Philippines where healthcare facilities may have resource limitations and patients often endure multiple admissions. **Key Principles:** 1. **Cephalocaudal Direction**: Begin at the head and move downward to the feet, allowing you to assess the body in a logical sequence. This prevents backtracking and keeps the patient oriented to what comes next. 2. **Bilateral Comparison for Symmetry**: Always compare left and right sides (eyes, ears, breasts, lung sounds, pulses, muscle strength) to identify asymmetries that suggest pathology. For example, unilateral leg edema may indicate deep-vein thrombosis (DVT), whereas bilateral edema suggests a systemic cause such as heart failure or hypoproteinemia. 3. **Grouping Techniques to Minimize Position Changes**: Position the patient to suit multiple regions before moving them. For instance, examine the head, neck, thorax, heart, lungs, and back while the patient is seated; then move to supine for the anterior chest, heart, and abdomen. This conserves the patient's energy—a critical concern in NCM Level II and III care where many patients are acutely ill or elderly. 4. **Integration of General Survey and Vital Signs First**: Before regional examination, perform the general survey (assess general appearance, level of consciousness, signs of distress) and obtain vital signs. These provide context for all subsequent findings. 5. **Privacy, Warmth, and Standard Precautions**: Maintain patient dignity by exposing only the area being examined, ensuring the room is warm, and explaining each step. Always wear gloves when contact with body fluids is possible, consistent with RA 9173 infection-control mandates. **Nursing Implication**: A systematic approach signals competence to both the patient and your healthcare team, builds trust, and ensures that subtle abnormalities are not missed due to haste or disorganization.

Proper preparation sets the stage for an efficient, thorough, and respectful assessment. In the Philippine healthcare context, where resources may be limited and patient flow high, organization and readiness are especially important. **Equipment to Gather:** - Stethoscope (warmed before use—a cold diaphragm startles patients) - Sphygmomanometer (manual or digital; many Philippine facilities still rely on manual mercury units) - Penlight or small flashlight (for pupil, throat, and ear canal examination) - Thermometer (oral, axillary, or tympanic, depending on patient condition and facility protocol) - Tape measure (for abdominal girth, limb circumference, or wound assessment) - Reflex hammer (for deep-tendon reflex testing) - Gloves and hand sanitizer - Otoscope and ophthalmoscope (if available and if you are trained) - Cotton-tipped applicators and gauze - Tuning fork (if performing vibration sense assessment) **Patient Preparation:** 1. **Explain the assessment**: "I will examine you from head to toe. This usually takes 20–30 minutes. I'll explain what I'm doing at each step, and please tell me if anything hurts or makes you uncomfortable." 2. **Ensure privacy**: Close curtains or doors; allow a family member to stay if the patient wishes (respecting Filipino family-centered care practices). 3. **Check comfort**: Ask the patient to void before abdominal assessment (a full bladder interferes with examination and makes percussion less accurate). Ensure the room is warm and the bed is at a comfortable height for you to examine without straining. 4. **Warm your hands and stethoscope**: Cold instruments are uncomfortable and may trigger guarding (muscle tensing) that limits examination accuracy. 5. **Position the patient appropriately**: For most of the assessment, use a semi-recumbent or upright position (60–90°). For the abdomen, use supine or dorsal recumbent (knees slightly bent to relax abdominal muscles). For the back, have the patient sit upright or lean forward. For gait and balance, have the patient stand. **Special Considerations for Philippine Patient Populations:** - **Elderly patients**: May tire easily; offer frequent rest breaks and adjust the sequence if necessary. - **Patients with limited English proficiency**: Use simple language or engage a family member or interpreter to explain findings and gather history. - **Patients in resource-limited settings**: Adapt by using available equipment (e.g., a simple light source instead of an ophthalmoscope; two-finger percussion if a reflex hammer is unavailable). - **Frail or dyspneic patients**: Reposition frequently and allow rest; do not force them to stand if it causes distress.

The integumentary system is the body's largest organ and reflects overall health, hydration status, oxygenation, nutrition, and immune function. Assessment of skin, hair, and nails provides clues to systemic diseases and local pathology. **Inspection and Palpation Techniques:** **Color:** Normal skin color varies widely among Filipino populations—from fair to brown to dark brown. Assess color against the patient's baseline and ethnic norm. Look at areas with less melanin (palms, soles, nail beds, lips, mucous membranes, conjunctivae) for more accurate detection of color changes. - **Cyanosis**: A bluish hue indicating hypoxemia (low blood oxygen). **Central cyanosis** (lips, tongue, mucous membranes) signals cardiopulmonary disease and is an emergency. **Peripheral cyanosis** (fingers, toes) may indicate poor circulation or cold exposure and is less urgent. In dark-skinned patients, cyanosis may appear as gray or dull color of the lips, tongue, or nail beds. - **Pallor**: Paleness suggesting anemia, poor perfusion, or shock. In dark-skinned patients, pallor appears as an ashy or gray tone in the skin. - **Jaundice**: Yellowing of the skin and sclera (whites of the eyes) due to bilirubin accumulation; suggests liver disease, hemolysis, or biliary obstruction. Note: In dark-skinned patients, jaundice is best seen on the sclera, hard palate, and palms. - **Erythema**: Redness indicating inflammation, fever, or infection. **Moisture and Texture:** - Normal skin is warm and dry (not clammy or dry/scaly). - **Diaphoresis** (excessive sweating) suggests fever, hypoglycemia, anxiety, or myocardial infarction—assess in conjunction with vital signs and other symptoms. - **Dry skin (xerosis)** may indicate dehydration, thyroid disease, or poor nutrition. **Turgor (Elasticity):** Pinch the skin on the forearm or back of the hand for 3 seconds, then release. **Normal turgor** means the skin recoils immediately (within 2 seconds). **Poor turgor** (skin remains tented or returns slowly) suggests dehydration, which is a significant concern in the Philippines where dehydration-related conditions are common in pediatric and elderly populations. - Mild dehydration: skin recoil in 2–3 seconds. - Moderate dehydration: skin remains tented for several seconds. - Severe dehydration: skin tenting is marked and prolonged. **Capillary Refill:** Press a nail bed or fingertip until blanched (whitened), then release. Normal refill is **less than 2–3 seconds** (the nail returns to its normal pink color quickly). Delayed refill (>3 sec) suggests poor peripheral perfusion, seen in shock, heart failure, or peripheral vascular disease. This simple test is especially useful in resource-limited Philippine settings where advanced hemodynamic monitoring may not be available. **Lesions:** Inspect and palpate for any abnormalities—macules, papules, vesicles, pustules, ulcers, or scars. Document the location, size (measure in centimeters), shape, color, and any drainage. For any suspicious lesion (irregular border, color variation, size >5 mm, bleeding), refer for further evaluation. **Hair:** Assess distribution (should be even over the scalp and body) and quality (texture, moisture). **Alopecia** (hair loss) in patches may suggest alopecia areata or fungal infection; diffuse hair loss may indicate nutritional deficiency, hormonal imbalance, or chemotherapy effect. **Nails:** - **Color**: Normal nails are pink with white lunulae (the crescent at the base). **Pale nails** suggest anemia or liver disease; **darkened nails** may indicate melanoma (especially in darker-skinned patients) or heavy metal exposure. - **Shape and angle**: The angle between the nail plate and nail bed is normally about **160°**. **Clubbing** (nail angle ≥180°, thickened fingertips) indicates chronic hypoxia (lung cancer, COPD, chronic bronchiectasis, congenital heart disease) or chronic liver disease. - **Nail beds**: Should be intact without separation from the plate. **Onycholysis** (separation) suggests psoriasis, fungal infection, or thyroid disease. - **Texture**: Nails should be smooth. Ridges, pitting, or brittleness may indicate nutritional deficiency, psoriasis, or systemic disease. **Edema:** Inspect for puffiness in dependent areas (feet, ankles, sacrum in bedridden patients). Palpate gently and assess whether the depression left by your finger **rebounds immediately** (non-pitting) or remains (pitting edema). Grade pitting edema on a 0–4+ scale: - **1+** = barely visible depression (2 mm); rapid rebound (≤2 sec) - **2+** = noticeable depression (4 mm); rebound in 3–5 sec - **3+** = deep depression (6 mm); rebound in >5 sec - **4+** = very deep depression (8 mm); rebound prolonged (>10 sec) Note whether edema is **unilateral** (suggests local cause like DVT, limb trauma, or lymph obstruction) or **bilateral** (suggests systemic cause like heart failure, liver disease, kidney disease, or malnutrition). **Nursing Implications and NANDA Diagnoses:** - **Impaired skin integrity** related to wounds, pressure ulcers, or lesions; nursing interventions include wound care, positioning, and nutritional support. - **Risk for impaired skin integrity** in patients with poor turgor, immobility, or incontinence; prevention focuses on turning, skin care, and moisture control. - **Fluid volume deficit** (dehydration) suggested by poor turgor, dry mucous membranes, and reduced capillary refill; interventions include fluid rehydration and monitoring intake/output. - **Ineffective peripheral tissue perfusion** suggested by cyanosis, delayed capillary refill, or edema; assess for arterial or venous insufficiency and monitor closely.

The head and neck examination screens for neurologic, vascular, and local pathology. Findings here can signal stroke, thyroid disease, infection, or mass lesions. **Head:** **Inspection:** - **Normocephalic**: Head should be proportionate to the body, without lumps, deformities, or scars. The skull should feel smooth when palpated. - **Symmetry**: Face should be symmetric; any asymmetry (droop, swelling, scars) is noted. - **Hair**: Distribution should be even; alopecia is noted above. **Abnormal findings:** - **Facial droop** (one side of the face droops, smile is asymmetric, eye may not close fully) suggests facial nerve (CN VII) palsy. When sudden, especially with arm weakness or slurred speech, this is a **stroke warning sign**—use the **FAST framework** (Face, Arm, Speech, Time) and report immediately. - **Bell's palsy** is a common cause of facial droop; it is idiopathic and affects only the face (not the arm or speech). - **Skull abnormalities**: Palpate for lumps, depressions, or points of tenderness. A bulging fontanelle in infants or soft-tissue swelling in adults may indicate increased intracranial pressure (ICP)—an emergency. **Neck:** **Inspection and Palpation:** - **Trachea position**: The trachea should be **midline**. Assess by palpating the trachea with your thumbs on either side of the neck and observing that the trachea does not deviate toward one side. **Tracheal deviation** away from the affected side suggests tension pneumothorax (emergency), mass lesion, or pleural effusion. - **Neck mobility**: Ask the patient to touch chin to chest (flexion), tilt head back (extension), and turn head to each side (rotation). Assess for **nuchal rigidity** (stiff neck, unable to flex chin to chest without pain)—a sign of meningitis, subarachnoid hemorrhage, or severe cervical arthritis. Test nuchal rigidity by gently attempting to flex the neck; if resistance is felt and the patient resists, meningeal irritation is suspected—**report immediately**. - **Neck veins**: With the patient at 45°, observe the internal jugular veins (IJVs). They should be visible only in the lower half of the neck when the patient is upright. **Jugular venous distension (JVD)** (visible high in the neck, or distended even when lying flat) suggests elevated central venous pressure, seen in heart failure, pericarditis, or superior vena cava obstruction. **Thyroid Examination:** The thyroid is a butterfly-shaped gland at the base of the neck, straddling the trachea. - **Inspection**: Look for enlargement or asymmetry. Ask the patient to swallow water (to elevate the thyroid gland) while you observe the neck. Thyroid tissue should move up with swallowing; this confirms the nodule or enlargement is part of the thyroid. - **Palpation**: Stand behind the patient. Place your fingers on the neck, just below the larynx, and ask the patient to swallow. Feel for the thyroid lobes rising with the swallow. **Normal thyroid** is small and nonpalpable or barely palpable (should not be visible on inspection or easily felt). **Thyroid enlargement (goiter)** is abnormal and may indicate: - Iodine deficiency (still seen in some Philippine provinces) - Grave's disease (hyperthyroidism) - Hashimoto's thyroiditis (hypothyroidism) - Thyroid nodules or cancer - If the thyroid is nodular (bumpy), hard, or fixed, refer for ultrasound and possible biopsy. **Lymph Nodes:** Palpate the lymph nodes in a systematic order: **preauricular** (in front of the ear), **postauricular** (behind the ear), **anterior cervical** (along the sternocleidomastoid muscle), **posterior cervical** (along the trapezius), **occipital** (back of the skull), and **supraclavicular** (above the collarbone). - **Normal lymph nodes** are nonpalpable or, if palpable, are small (≤1 cm), soft, tender, mobile, and in clusters. - **Abnormal lymph nodes**: - **Hard, fixed, or immobile nodes** → suggest malignancy (cancer). - **Enlarged, tender nodes** → suggest infection (streptococcal throat, tuberculosis, HIV). - **Supraclavicular nodes** → are rarely normal and often suggest malignancy; always refer. - Document size in centimeters, consistency (soft, firm, hard), mobility, tenderness, and location. **Nursing Implications and NANDA Diagnoses:** - **Risk for impaired cerebral tissue perfusion** related to tracheal deviation or suspected stroke; assessment includes FAST screening, vital signs, and neuro checks. - **Risk for infection** related to signs of meningitis (nuchal rigidity); droplet precautions may be needed pending diagnosis. - **Knowledge deficit** regarding thyroid disease or lymph node enlargement; patient education and follow-up referral are essential.

The HEENT exam assesses sensory organs (vision, hearing), and screens for infection, trauma, and cranial nerve function. Many of the cranial nerves (II–XII) are tested during this exam. **EYES:** **Inspection and Visual Assessment:** - **Placement and symmetry**: Eyes should be level (horizontally aligned) and symmetric. Assess for **ptosis** (drooping eyelid, may be unilateral or bilateral), which can indicate CN III (oculomotor) palsy, myasthenia gravis, or Horner's syndrome. - **Sclera** (white of the eye): Should be white or slightly yellow in darker-skinned individuals. **Icteric sclera** (yellowing) indicates jaundice and suggests liver disease or hemolysis. **Injected sclera** (redness) suggests conjunctivitis or uveitis. - **Conjunctiva** (membrane lining the eyelid): Should be pink and moist. **Pale conjunctiva** suggests anemia; **redness** suggests infection or allergy. - **Pupil assessment - PERRLA**: - **P**upils: Should be round and regular in shape. - **E**qual: Pupils should be the same size bilaterally. **Anisocoria** (unequal pupils) can be normal (physiologic) or abnormal (indicating CN III palsy, Adie's tonic pupil, or Horner's syndrome). If new-onset and unilateral, it warrants evaluation. - **R**eactive to **L**ight: Shine a light directly into the pupil; it should constrict (direct response) and the opposite pupil should also constrict (consensual response). **Non-reactive pupils** suggest increased intracranial pressure, drug effect (opioids), or death. - **R**eactive to **A**ccommodation: Ask the patient to focus on your finger as you bring it toward their nose; pupils should constrict (accommodation) and the eyes should converge (cross slightly). This tests CN II (optic) and CN III (oculomotor). - **Normal pupil size**: 3–5 mm in normal light. **Pinpoint pupils** (<3 mm) suggest opioid use, pontine hemorrhage, or glaucoma. **Dilated pupils** (>5 mm, non-reactive) are a red flag for neurologic emergency, drug effect (cocaine, amphetamines), or death. - **Visual acuity** (CN II – optic nerve): Use a Snellen chart or ask the patient to count fingers at 2 feet, read newsprint, or describe objects across the room. **Normal visual acuity** is ~20/20. Document the result for each eye separately (e.g., "OD 20/20, OS 20/30") and note whether the patient wears corrective lenses. **Vision loss** warrants referral to an eye specialist. - **Extraocular movements (EOMs)** (CN III, IV, VI): Ask the patient to keep their head still and follow your finger as you move it in the shape of an H (to test all six cardinal positions: up, down, left-up, left-down, right-up, right-down). Movements should be smooth and coordinated; eyes should move together (conjugate gaze). **Nystagmus** (involuntary eye jerking) or diplopia (double vision) suggests cerebellar disease, vestibular disorder, or brainstem pathology. - **Alignment**: Assess the **corneal light reflex test** (Hirschberg test): shine a light in the patient's eyes and observe the reflection on the cornea. It should be in the same position on both eyes. **Strabismus** (eyes not aligned) is abnormal and may indicate CN III, IV, or VI palsy. **Abnormal Findings and Red Flags:** - **Fixed, dilated pupil** (one or both pupils dilated and non-reactive) → neurologic emergency (increased ICP, brain herniation, CN III palsy); report immediately. - **Sudden vision loss** → retinal artery occlusion, retinal detachment, or acute glaucoma; ophthalmology referral urgent. - **Nystagmus with vertigo** → vestibular disorder, brainstem pathology; full neuro assessment needed. **EARS:** **Inspection and Otoscopic Examination:** - **External ear** (pinna): Inspect for deformity, lesions, or discharge. The pinna should align with the **outer canthus of the eye** (horizontal line through the outer corner of the eye). **Low-set ears** (below this line) are associated with developmental syndromes. - **Ear canal** (external auditory canal): Use an otoscope with the largest speculum that fits. Insert gently, angling the speculum to visualize the canal. The canal should be patent (open) and free of cerumen (earwax) buildup or discharge. - **Tympanic membrane** (TM): Should be **pearly gray**, translucent, intact, with a light reflex visible. The "cone of light" (light reflex) is typically visible in the lower anterior quadrant. The handle of the malleus should be visible running from the center toward the lower part of the TM. **Abnormal findings:** - **Red, bulging TM** → acute otitis media (infection); may have fluid level or air-fluid level visible. - **Purulent discharge** → otitis media with perforation; culture if available. - **TM perforation** → visible hole in the TM; refer to ENT; precautions against water entry (ear protection during bathing). - **Retracted TM** → serous otitis media (fluid behind the TM without infection); common in children and may cause conductive hearing loss. - **Cerumen impaction** → earwax blocking the canal and reducing hearing; may require removal. **Hearing Assessment** (CN VIII – vestibulocochlear nerve): - **Whisper test**: Stand at arm's length behind the patient. Whisper a number or phrase (e.g., "ninety-nine") and ask the patient to repeat it. Do this for each ear, occluding the non-test ear. Normal hearing allows the patient to hear the whisper. **Conductive hearing loss** (problem with outer or middle ear) allows whispered speech but not other sounds. **Sensorineural hearing loss** (problem with inner ear or nerve) causes difficulty hearing both whispered and normal speech. - **Weber test**: Place a vibrating tuning fork on the midline of the forehead. Sound should be heard equally in both ears. **Lateralization** (sound louder in one ear) suggests conductive loss on that side or sensorineural loss on the opposite side. - **Rinne test**: Place a vibrating tuning fork on the mastoid bone (bone conduction), then move it near the ear canal (air conduction). Normally, **air conduction is heard longer** than bone conduction (AC > BC). If BC > AC, conductive hearing loss is present. **NOSE:** **Inspection and Palpation:** - **External nose**: Should be midline, symmetric, without deformity or lesions. - **Internal nose** (using penlight and nasal speculum if available): Inspect the nasal mucosa (should be pink and moist), septum (should be midline), and turbinates (inferior turbinate normally enlarged, not obstructing airflow). **Abnormal findings:** - **Deviated septum** → may obstruct airflow; patient may report nasal congestion or sleep apnea. - **Nasal polyps** → pale, boggy, grape-like masses; common in chronic rhinitis or cystic fibrosis. - **Purulent discharge** → suggests sinusitis or infection. - **Epistaxis** (nosebleed) → may be due to trauma, dry air, hypertension, or coagulopathy; assess severity and bleeding source. **THROAT:** **Inspection:** Ask the patient to say "ahh" and open the mouth wide. Use a penlight and tongue depressor (place the depressor on the tongue, pushing down gently, careful not to gag the patient). - **Soft palate and uvula** (CN IX, X – glossopharyngeal and vagus): The soft palate should elevate symmetrically when the patient says "ahh"; the uvula should rise in the **midline**. **Uvula deviation** (tilted to one side) indicates CN X palsy on the opposite side (the vagus nerve pulls the uvula toward the functioning side). - **Oropharynx** (back of the throat): Inspect the posterior pharyngeal wall, tonsils, and anterior/posterior tonsillar pillars. - **Tonsils** (CN IX – afferent for gag reflex): Should be small or nonpalpable (grade 0–1+) and pink. Grade them 0–4+: - **0** = not visible - **1+** = small, within tonsillar fossa - **2+** = enlarged, reaching halfway to the midline - **3+** = enlarged, nearly touching the midline - **4+** = very enlarged, meeting at midline ("kissing tonsils") - **Enlarged tonsils** (2–4+) suggest acute pharyngitis or chronic tonsillitis. - **Exudative tonsils** (white or yellow coating) suggest streptococcal pharyngitis or infectious mononucleosis; refer for throat culture and testing (Rapid Strep Test, mono spot). - **Gag reflex** (CN IX and X): Gently touch the posterior pharyngeal wall with the tongue depressor. Normal response is a visible contraction of the pharyngeal muscles and the patient's feeling of gagging. **Absent gag reflex** suggests CN IX/X involvement (brainstem stroke, neuromuscular disorder) and increases aspiration risk—implement dysphagia precautions (NPO, thickened liquids, head elevated 30°, feeding assistance). - **Odor of breath**: **Fruity odor** may indicate diabetic ketoacidosis (DKA); **fetid odor** suggests poor oral hygiene, dental disease, or lung abscess; **ammonia odor** suggests liver disease (hepatic encephalopathy). **Abnormal findings:** - **Uvula deviation** → CN X palsy; assess for other signs of stroke or brainstem involvement. - **Asymmetric soft palate elevation** → CN X palsy on that side. - **Enlarged/exudative tonsils** → pharyngitis; throat culture indicated; isolation if strep is suspected. - **Absent gag reflex** → dysphagia risk; NPO pending swallow evaluation. - **Posterior pharyngeal redness or exudate** → pharyngitis or abscess. **Nursing Implications and NANDA Diagnoses:** - **Risk for injury** (falls) related to vision loss; interventions include environmental modification, orientation to surroundings, and assistance with ambulation. - **Ineffective communication** related to hearing loss; interventions include face-to-face communication, written materials, hearing aids (if available). - **Risk for infection** related to signs of otitis media, pharyngitis, or sinusitis; monitoring for symptom escalation and appropriate referral/treatment. - **Risk for aspiration** related to absent gag reflex or swallowing difficulty; dysphagia precautions and speech therapy consultation as indicated.

The respiratory assessment evaluates air movement, lung function, and oxygenation. Abnormal breath sounds and respiratory patterns can signal airway obstruction, infection, collapse, or fluid—all potentially life-threatening and requiring immediate intervention. **Respiratory Rate and Pattern:** - **Normal rate**: 12–20 breaths per minute (RR) in adults; count for 60 seconds. - **Abnormal patterns**: - **Tachypnea** (RR >20) → fever, pain, anxiety, hypoxemia, metabolic acidosis, heart failure, anemia. - **Bradypnea** (RR <12) → CNS depression (opioids, barbiturates, head injury), hypothermia. - **Apnea** (cessation of breathing) → neurologic emergency; initiate rescue breathing and call for help. - **Cheyne-Stokes respiration** (crescendo-decrescendo pattern with apneic periods) → seen in heart failure, neurologic disease, sepsis; indicates severe illness. - **Kussmaul respiration** (deep, rapid, labored breathing) → diabetic ketoacidosis (DKA); associated with fruity-smelling breath. - **Pursed-lip breathing** (exhales against pursed lips) → seen in COPD patients trying to maintain positive airway pressure. - **Work of breathing**: Normal breathing is quiet and effortless. **Labored breathing** (dyspnea), use of accessory muscles (intercostal, supraclavicular retractions, abdominal muscles), nasal flaring (in infants), or grunting suggests respiratory distress—assess severity and oxygenation immediately. **Chest Wall Shape and Movement:** - **Anteroposterior (AP) to transverse diameter ratio**: Normal is approximately **1:2** (AP shorter than width). **Barrel chest** (AP:transverse ~1:1) suggests chronic air trapping, seen in COPD. **Pectus carinatum** (pigeon breast, sternum protrudes) is less common. **Pectus excavatum** (sunken sternum) is usually benign but can restrict breathing if severe. - **Symmetric chest expansion**: Observe the chest from the front and back. Place hands on the chest (one on each side) and feel the ribs rise symmetrically during inspiration. **Asymmetric expansion** (one side rises more than the other) suggests pneumonia, atelectasis (collapse), pleural effusion, or pneumothorax on the side with reduced expansion. - **Kyphosis, scoliosis, or spinal deformities** can restrict rib cage movement and lead to respiratory compromise over time. **Palpation:** - **Tactile fremitus**: Place the palms flat on the chest (one side at a time) and ask the patient to say "99." You should feel vibrations transmitted through the lungs to the chest wall. **Increased fremitus** (stronger vibrations) suggests consolidation (pneumonia) or atelectasis. **Decreased fremitus** suggests air-filled spaces (emphysema, pneumothorax) or fluid (pleural effusion). - **Chest tenderness**: Palpate for rib fractures, muscle strain, or costochondritis (inflammation at the rib-cartilage junction). **Percussion:** Percuss the chest from apex to base, comparing both sides. Use the "plexor finger" (usually the middle finger of your dominant hand) to tap the "plessor finger" (middle finger of your non-dominant hand placed flat on the chest). Listen and feel for the vibration. - **Normal percussion note**: **Resonance** over the lung fields (a clear, hollow sound). **Tympany** (a high-pitched, drum-like sound) is normal over the stomach and may be heard if the patient has abdominal distention pushing up on the lungs. - **Abnormal percussion notes**: - **Dullness** (a flat, thudding sound) → suggests consolidation (pneumonia), atelectasis, or pleural effusion (fluid); compare to bony areas (dullness over the ribs and spine is normal). - **Hyperresonance** (a hollow, louder-than-normal sound) → suggests trapped air (emphysema, pneumothorax, asthma); bilateral hyperresonance is common in COPD, whereas unilateral hyperresonance suggests pneumothorax. - **Diaphragmatic excursion**: Percuss downward from the top of the lung until the sound changes from resonance to dullness (indicating the top of the liver or spleen). Mark this spot. Then have the patient take a deep breath and percuss again; the spot should move down 1–2 cm (the diaphragm moving down). **Limited excursion** (<1 cm) suggests diaphragm weakness or pleural effusion. **Auscultation:** Use the diaphragm of the stethoscope (not the bell) and listen from the apex to the base, side to side, comparing bilaterally. Have the patient breathe deeply through the mouth. Listen for duration of inspiration vs. expiration, pitch, and intensity. **Normal breath sounds:** - **Vesicular breath sounds** (soft, low-pitched, breezy): heard over most of the peripheral lung fields; inspiration is longer and louder than expiration (I > E). This is the normal lung sound you'll hear in the majority of the chest. - **Bronchovesicular breath sounds** (medium pitch and intensity): heard over the main bronchi (around the 1st and 2nd intercostal spaces anteriorly and between the shoulder blades posteriorly); inspiration and expiration are equal (I = E). - **Bronchial breath sounds** (high-pitched, loud, like wind rushing through a tube): heard over the trachea; expiration is longer than inspiration (E > I). - **Absence of breath sounds** (silent lung field) → suggests pneumothorax, pleural effusion, or severe consolidation with no air movement; this is an emergency if bilateral or acute. **Abnormal breath sounds (Adventitious Sounds):** - **Crackles (formerly called "rales")**: **Discontinuous** popping/crackling sounds, like opening Velcro or cellophane crinkling. - **Fine crackles** (soft, high-pitched, brief) → fluid in small alveoli; heard in pneumonia, pulmonary edema (heart failure), pulmonary fibrosis, atelectasis; typically occur in late inspiration. - **Coarse crackles** (louder, lower-pitched, longer) → fluid in larger airways; heard in bronchiectasis, severe pneumonia, pulmonary edema; typically occur in early-to-mid inspiration. - **Important**: Crackles that clear after coughing suggest atelectasis or secretions; persistent crackles suggest pathology requiring treatment. - **Wheezes**: **Continuous** high-pitched musical sounds, like air being forced through narrowed airways. - **Expiratory wheeze** → airway narrowing in expiration (typical of asthma or COPD exacerbation). - **Inspiratory wheeze** → airway narrowing in inspiration; less common but can occur with upper-airway obstruction. - **Polyphonic wheezes** (multiple pitch simultaneously) → multiple airways narrowing at different rates (asthma, COPD). - **Monophonic wheeze** (single pitch) → single airway narrowing (tumor, foreign body, mucous plug). - **Rhonchi** (formerly called "sonorous rales"): **Continuous** low-pitched snoring-like sounds, usually in expiration. Suggest secretions in larger airways (bronchi); often clear with coughing. - **Pleural friction rub**: A **grating or creaking** sound, like the sound of rubbing leather together; heard in both inspiration and expiration. Suggests inflamed pleura (pleurisy, pulmonary infarct); often accompanied by pleuritic chest pain (sharp pain worse with breathing). - **Stridor**: A **high-pitched, musical breathing sound** heard without the stethoscope, typically in inspiration (though can be biphasic). **This is a RED FLAG** indicating upper-airway obstruction (laryngitis, croup, epiglottitis, foreign body, anaphylaxis). **Stridor requires immediate assessment and intervention—prepare for potential airway emergency.** **Special Respiratory Findings:** - **Barrel chest + chronic bronchitis + emphysema** → COPD; these patients often use pursed-lip breathing and may have diminished breath sounds bilaterally. - **Unilateral crackles + fever + productive cough with purulent sputum** → pneumonia; may have associated dullness on percussion and increased tactile fremitus. - **Bilateral fine crackles in dependent areas + orthopnea (difficulty breathing when lying flat) + JVD + peripheral edema** → pulmonary edema from heart failure; consider diuretics and afterload reduction. - **Unilateral absent breath sounds + hyperresonance on percussion + tracheal deviation + hypotension + JVD** → tension pneumothorax; this is a **life-threatening emergency**—needle decompression (14-gauge needle at 2nd intercostal space, midclavicular line) may be needed before imaging. **Sputum Assessment:** If the patient coughs up sputum, observe and document: - **Color**: clear (normal), white/foamy (pulmonary edema, viral infection), yellow/green (bacterial infection), blood-tinged (hemoptysis—suggests infection, cancer, or pulmonary infarct), or frank blood (massive bleeding). - **Consistency**: thick, thin, frothy, or bloody. - **Odor**: foul odor suggests anaerobic infection (lung abscess, bronchiectasis). **Nursing Implications and NANDA Diagnoses:** - **Impaired gas exchange** related to pneumonia, heart failure, COPD, or pneumothorax; interventions include supplemental oxygen, positioning (head elevated), medications (bronchodilators, diuretics), and monitoring SpO2 and ABGs. - **Ineffective airway clearance** related to secretions, mucous plugging, or foreign body; interventions include suctioning, coughing and deep-breathing exercises, nebulized medications, chest physiotherapy. - **Ineffective breathing pattern** related to pain (rib fracture), CNS depression, or neuromuscular weakness; interventions include pain management, respiratory support, positioning. - **Risk for aspiration** related to diminished gag reflex or swallowing difficulty; implement precautions (NPO, head elevated, feeding assistance).

Cardiovascular assessment evaluates the heart's function as a pump, peripheral perfusion, and venous return. Heart sounds, murmurs, pulses, and signs of fluid status are key findings that guide diagnosis and treatment. **Heart Inspection:** - **Precordium** (front of the chest): Inspect for any visible pulsations, scars (from prior cardiac surgery), or abnormalities. The **apical impulse** (PMI—Point of Maximum Impulse) should not be visibly prominent; if you see a hyperdynamic or displaced impulse, cardiomegaly or left ventricular hypertrophy is suspected. **Heart Palpation – Locating the PMI:** The PMI is normally at the **5th intercostal space (ICS), left midclavicular line (MCL)**. To find it: 1. Locate the 2nd ICS (at the angle of Louis, where the rib meets the sternum—this is a prominent landmark). 2. Count down to the 5th ICS. 3. Trace laterally to the midclavicular line (run your finger from the middle of the clavicle down). 4. Gently palpate; you should feel a brief impulse (~2 cm in diameter, lasting less than one-third of systole) during ventricular contraction. **Normal findings:** - PMI is **palpable** but not prominent (just barely felt). - PMI is located at the **5th ICS, MCL**. - PMI is **<2 cm in diameter**. - PMI lasts **<1/3 of systole** (less than half the duration of the heartbeat). **Abnormal findings:** - **Displaced PMI** (lateral of MCL or below 5th ICS) → suggests cardiomegaly (enlarged heart) or left ventricular hypertrophy; seen in heart failure, hypertension, aortic valve disease. - **Hyperdynamic or prominent PMI** (easily palpable, forceful) → suggests increased cardiac output or forceful contraction; seen in anemia, fever, hyperthyroidism, or anxiety. - **Thrill** (a palpable vibration, like a cat purring) → suggests turbulent blood flow; associated with significant murmurs (usually indicates severe valve disease); palpate at the valve areas to localize. **Heart Auscultation – Listening to Heart Sounds:** Use the **diaphragm** of the stethoscope (not the bell) and listen at four valve areas in a systematic order: **Mnemonic: "APE To Man"** - **A**ortic area: **2nd right intercostal space (ICS)**, right sternal border - **P**ulmonic area: **2nd left ICS**, left sternal border - **E**rb's point: **3rd left ICS**, left sternal border (overlap of aortic and pulmonic) - **T**ricuspid area: **4th left ICS**, left sternal border (right ventricular inflow) - **M**itral (Apical) area: **5th left ICS, midclavicular line** (left ventricular outflow; best place to hear apical sounds) Listen for the rhythm, rate, and **cardiac cycle**: **S1** ("lub"), **systole** (silence), **S2** ("dub"), **diastole** (silence). **S1 (First Heart Sound) – "Lub":** - Caused by: closure of **atrioventricular (AV) valves** (mitral and tricuspid). - **Loudest at the apex** (mitral area). - Marks the **start of systole** (ventricular contraction). - Should be a single sound (or may split slightly into M1 and T1 components, but this is normally inaudible). - **Abnormal S1**: - **Loud S1** → mitral stenosis (stiff valve) or in athletic young people (normal variant). - **Soft S1** → mitral regurgitation, first-degree AV block, or poor cardiac contractility. - **Split S1** (clearly audible two components) → right bundle branch block or ventricular ectopy (rare finding). **S2 (Second Heart Sound) – "Dub":** - Caused by: closure of **semilunar valves** (aortic and pulmonic). - **Loudest at the base** (aortic and pulmonic areas). - Marks the **end of systole and start of diastole** (ventricular relaxation). - **Physiologic split of S2**: During inspiration, venous return to the right side of the heart increases, delaying pulmonic valve closure slightly; you may hear two components (A2, then P2) during inspiration. During expiration, the sounds merge into one. This is **normal** in healthy young people. - **Abnormal S2**: - **Wide split S2** (clearly audible split in expiration, not just inspiration) → right bundle branch block, left ventricular outflow obstruction (aortic stenosis), or ventricular septal defect (VSD). - **Fixed split S2** (persistent split in both inspiration and expiration) → atrial septal defect (ASD) or pulmonary hypertension. - **Single S2** (no split) → severe aortic stenosis or pulmonary hypertension (both valves close simultaneously). **S3 (Third Heart Sound) – "Ventricular Gallop":** - A low-pitched, soft sound heard in **early diastole**, after S2. The rhythm sounds like "lub-dub-DUH," similar to the word "Kentucky." - **Normal in children and young adults** (age <30, athletic individuals); reflects rapid ventricular filling. - **Abnormal (pathologic S3) in adults >30**: indicates impaired ventricular function, often due to systolic heart failure, fluid overload, or dilated cardiomyopathy. Nursing diagnosis: **Fluid volume excess** related to decreased cardiac contractility. - **Clinical context**: S3 + orthopnea + JVD + crackles = pulmonary edema from heart failure. **S4 (Fourth Heart Sound) – "Atrial Gallop":** - A low-pitched sound heard in **late diastole**, just before S1. The rhythm sounds like "DUH-lub-dub," similar to the word "Tennessee." - **Always abnormal** in adults (normal only in elite athletes); indicates a **stiff ventricle** unable to relax properly. Reflects atrial contraction against resistance (decreased ventricular compliance). - **Associated with**: hypertension, aortic stenosis, hypertrophic cardiomyopathy, acute myocardial infarction (MI), or coronary artery disease (CAD). - **Clinical significance**: S4 indicates increased ventricular stiffness; patient may progress to heart failure. **Murmurs:** A murmur is an **abnormal heart sound** caused by turbulent blood flow. Characterize any murmur by: 1. **Timing** (systolic or diastolic) 2. **Location** (where it's loudest) 3. **Radiation** (does it spread to the carotids, axilla, or back?) 4. **Quality** (high-pitched, low-pitched, musical, blowing) 5. **Intensity** (grade 1–6): - **Grade 1** = barely audible, faint - **Grade 2** = quiet but easily heard - **Grade 3** = moderately loud - **Grade 4** = loud with palpable thrill - **Grade 5** = very loud, thrill easily palpable - **Grade 6** = audible without stethoscope, thrill palpable **Common murmurs:** - **Aortic stenosis** (AS): **Systolic, 2nd right ICS, radiates to carotids**, crescendo-decrescendo (diamond-shaped), high-pitched. Indicates narrowed aortic valve; severe AS can cause syncope (fainting) or heart failure. - **Aortic regurgitation** (AR): **Diastolic, 3rd–4th left ICS**, high-pitched, blowing. Indicates leaky aortic valve. - **Mitral regurgitation** (MR): **Systolic, apex, radiates to axilla**, high-pitched, holosystolic (throughout systole). Common after myocardial infarction or in rheumatic heart disease. - **Mitral stenosis** (MS): **Diastolic, apex, low-pitched**, preceded by an opening snap. Indicates narrowed mitral valve; causes atrial fibrillation and thromboembolic risk. - **Innocent murmurs** (common in children and pregnancy): usually **soft, early systolic, no radiation, no associated symptoms**; no intervention needed but refer for echocardiography if uncertain. **Heart Rate and Rhythm:** - **Normal rate**: 60–100 beats per minute (bpm) at rest in adults; athletes may have rates 50–60. - **Tachycardia** (>100 bpm) → fever, pain, anxiety, anemia, hyperthyroidism, heart failure, sepsis. - **Bradycardia** (<60 bpm) → athletic conditioning (normal), hypothyroidism, beta-blocker use, heart block, or sinus node disease. - **Rhythm**: - **Regular rhythm** = consistent interval between beats; normal. - **Irregular rhythm** = variable intervals; may indicate: - **Atrial fibrillation** (rapid, chaotic rhythm; no organized P waves on ECG); increased stroke risk—anticoagulation needed. - **Premature contractions** (occasional extra beats); usually benign unless frequent. - **Heart block** (dropped beats, pauses); varies in severity; may require pacemaker. **Peripheral Vascular Assessment:** **Pulses:** Palpate peripheral pulses and assess bilateral symmetry. Grade pulses on a **0–3+ scale** (or 0–4+): - **0** = absent - **1+** = diminished/weak - **2+** = normal, strong, easily palpable - **3+** (or 4+) = bounding, prominent, hyperkinetic Assess at: **carotid** (neck), **radial** (wrist), **femoral** (groin), **popliteal** (behind knee), **dorsalis pedis** (top of foot), **posterior tibial** (behind ankle). Compare **bilaterally** for symmetry. **Abnormal findings:** - **Diminished/absent pulses** → suggest arterial insufficiency; assess for coolness, pallor, pain with activity, and ulceration. Warn patient not to cross legs (increases compression), to avoid smoking (vasoconstriction), and to inspect feet regularly. - **Bounding pulses** (3+) → suggest high cardiac output (anemia, fever, hyperthyroidism), aortic regurgitation, or systolic hypertension. - **Asymmetric pulses** (stronger on one side) → suggest arterial obstruction on the weaker side. - **Carotid bruits** (listen with stethoscope; turbulent flow sounds like a whooshing murmur) → suggest carotid artery stenosis (narrowing); if acute, refer for urgent carotid imaging to assess stroke risk. **Extremity Assessment:** - **Temperature and color**: Should be warm, pink, and symmetric. **Coolness, pallor, or cyanosis** suggest poor perfusion. - **Edema** (covered in the integumentary section): - **Unilateral edema** (one leg) → suggests DVT, lymphatic obstruction, or local trauma; DVT is a medical emergency (risk of pulmonary embolism). - **Bilateral edema** → suggests systemic cause (heart failure, liver disease, kidney disease, malnutrition). - **Skin changes**: Look for shiny, hairless skin, ulcers (especially on the heels, toes, or lateral ankles—areas of pressure), or skin color changes (redness, brownish discoloration) suggesting chronic venous or arterial disease. - **Homans' sign** (calf pain on dorsiflexion of the foot) → may suggest DVT, but low sensitivity; clinical assessment plus D-dimer or ultrasound is more reliable. **Venous Assessment:** - **Jugular venous pressure (JVP)**: Assess with the patient reclined at 45°. Look at the internal jugular veins (IJVs) on either side of the neck. They should be visible only in the lower half of the neck when the patient is upright; they are not visible when the patient sits up. **Jugular venous distension (JVD)** (visible high in the neck or distended even when sitting up) suggests **elevated central venous pressure** (CVP) and is a sign of right heart failure, pericarditis, superior vena cava obstruction, or fluid overload. JVD + peripheral edema + hepatomegaly = classic triad of right heart failure. - **Hepatojugular reflux** (abdominal compression): With the patient at 45°, gently compress the abdomen (over the liver) and observe the JVD. An increase in JVD with compression (reflux) confirms elevated CVP. This simple bedside test is useful in diagnosing heart failure. **Nursing Implications and NANDA Diagnoses:** - **Decreased cardiac output** related to heart failure, arrhythmia, or valvular disease; interventions include cardiac monitoring, oxygen therapy, medications (inotropes, diuretics, vasodilators), and position (semi-Fowler's for easier breathing). - **Fluid volume excess** related to heart failure or renal disease; evidenced by edema, JVD, crackles; interventions include diuretics, fluid restriction, salt restriction, and monitoring intake/output. - **Risk for tissue perfusion, peripheral, ineffective** related to arterial or venous insufficiency; interventions include leg elevation (for venous), keeping legs dependent (for arterial), skin care, anticoagulation if indicated, and patient education on foot care and activity modification. - **Risk for thromboembolism** related to atrial fibrillation or DVT risk factors; anticoagulation (warfarin, novel anticoagulants) and DVT prophylaxis (compression stockings, sequential compression devices, early mobilization) are key.

Abdominal assessment is performed using the **modified sequence: Inspect → Auscultate → Percuss → Palpate**. This order is critical because palpation and percussion can alter bowel sounds (making them seem artificially diminished or absent). **Abdominal Anatomy and Quadrants:** Divide the abdomen into **four quadrants** (by drawing an imaginary vertical line from the xiphoid process to the pubic symphysis and a horizontal line through the umbilicus) or into **nine regions** (three rows of three). Knowing which organs lie in each quadrant/region helps you interpret findings: - **Right upper quadrant (RUQ)**: liver, gallbladder, right kidney. - **Left upper quadrant (LUQ)**: spleen, left kidney, stomach. - **Right lower quadrant (RLQ)**: appendix, right ovary/testicle. - **Left lower quadrant (LLQ)**: sigmoid colon, left ovary/testicle. **1. Inspection:** - **Shape and contour**: - **Flat** (normal, especially in lean individuals). - **Rounded** (normal, especially in individuals with excess adipose tissue). - **Distended** (abnormal; suggests gas, ascites, obesity, or organomegaly). - **Scaphoid** (sunken; suggests severe malnutrition or fluid loss). - **Symmetry**: Abdomen should be symmetric; asymmetry may suggest organomegaly (enlarged organ), mass, or obstruction. - **Skin**: Inspect for scars (note location and approximate time of surgery from scar appearance—fresh scars are red, older scars are white), striae (stretch marks, common in pregnancy or rapid weight gain), dilated veins, or discoloration. **Cullen's sign** (bluish discoloration around the umbilicus) suggests intra-abdominal bleeding (severe pancreatitis, ruptured aneurysm). **Grey Turner's sign** (discoloration on the flanks) also suggests intra-abdominal bleeding. - **Umbilicus**: Should be midline, intact, and clean. **Umbilical discharge or granulation tissue** suggests infection or a patent urachus (rare congenital abnormality). - **Movement**: Observe the abdomen during respiration. Normally, the abdomen rises during inspiration (abdominal/diaphragmatic breathing). **Rigid, board-like abdomen that does not move** is abnormal and suggests peritoneal irritation (peritonitis)—an emergency. - **Visible pulsations**: You may see the **aortic pulsation** in lean individuals (normal). **Visible peristalsis** (wave-like movements) is abnormal and suggests bowel obstruction, especially if accompanied by abdominal distention. **2. Auscultation (Listen BEFORE Palpating):** Use the **diaphragm** of the stethoscope. Listen in all four quadrants for **bowel sounds**. The stomach and bowel produce sounds as food and gas move through (peristalsis). - **Normal bowel sounds**: **5–30 per minute**; a mix of clicks, gurgles, and quiet intervals. Listen for at least 30 seconds in each quadrant; if you want to document "absent" bowel sounds, listen for a full **5 minutes** in one quadrant before concluding sounds are truly absent (delayed/hypoactive sounds may mimic absence). - **Abnormal bowel sounds**: - **Hyperactive** (frequent, loud, rushing, borborygmi—audible gurgling) → suggests early bowel obstruction, diarrhea, or hunger. - **Hypoactive** (diminished, faint, >30 sec between sounds) → suggests late obstruction, peritonitis, or ileus (paralysis of the bowel from anesthesia, electrolyte imbalance, opioids, or peritoneal irritation). - **Absent** (after listening 5 minutes) → severe ileus, peritonitis, or advanced obstruction; requires immediate intervention (NPO, IV fluids, NG tube, possible surgery). - **Tinkling or high-pitched sounds** → may suggest early/mechanical obstruction (liquid/gas collects above the obstruction, creating characteristic sounds). - **Bruits** (vascular sounds, like a whooshing murmur): Listen over the aorta (epigastrium) and iliac arteries (over the iliac regions). **Presence of a bruit** suggests turbulent flow, often from arterial stenosis or an **aortic aneurysm**—refer for imaging (ultrasound or CT). This is different from bowel sounds. **3. Percussion:** Percuss all four quadrants. Listen and feel for the vibration. - **Normal percussion note**: **Tympany** (a high-pitched, hollow, drum-like sound) is the most common sound, reflecting gas in the bowel and stomach. - **Dullness** (a flat, thudding sound) suggests solid organs, fluid, or stool. Dullness in the lower abdomen (pelvis) can be normal (full bladder, stool in colon) but persistent dullness warrants further assessment. - **Shifting dullness** (the dull area shifts when the patient changes position—e.g., from lying on the right side to the left side): suggests **ascites** (fluid in the peritoneal cavity), a sign of cirrhosis, heart failure, kidney disease, cancer, or peritonitis. Confirm with **fluid wave** test: have the patient place one hand on the midline of the abdomen (to stop vibration through subcutaneous fat); percuss on one side and feel for a wave of fluid on the other side. **4. Palpation (After Auscultation and Percussion):** Warm your hands. Ask the patient to relax and take slow, deep breaths through the mouth. **Start with superficial palpation**, moving gradually to deeper palpation. **Superficial palpation** (light touch, 1–2 cm depth): - Assess for tenderness, guarding (muscle tensing, patient resisting your pressure), or rigidity (hardness/stiffness that does not relax, indicating peritoneal irritation). - **Guarding** can be voluntary (patient tensing from anxiety or pain) or involuntary (protective reflex indicating peritonitis). - Ask the patient to cough; if coughing makes pain worse, peritonitis is likely. **Deep palpation** (pressing with flattened hand, 4–6 cm depth): - **Rebound tenderness** (Blumberg's sign): Slowly press down deeply in one area, then quickly release. If the patient experiences sharp pain on release (rebound), peritoneal irritation is present. This is a classic sign of peritonitis (burst appendix, perforated ulcer) and requires emergency surgery. - **Liver palpation**: Place your left hand under the patient's right ribcage (at the waist) and support the liver. Place your right hand below the right costal margin (edge of the rib cage) and press upward gently, asking the patient to take a deep breath. As they breathe in and the liver descends, you may feel the liver edge. **Normal liver**: nonpalpable or just barely palpable below the right costal margin, firm, smooth, and nontender. **Liver span** at the right midclavicular line is normally 6–12 cm. **Hepatomegaly** (enlarged liver, palpable >2 cm below the costal margin) suggests cirrhosis, heart failure, cancer, or hepatitis. - **Spleen palpation**: Place your left hand under the patient's left ribcage (at the waist) and support the spleen. Palpate with your right hand below the left costal margin, asking the patient to take a deep breath. **Normal spleen**: nonpalpable (does not project below the costal margin). **Splenomegaly** (enlarged, palpable) suggests infection (EBV, malaria), leukemia, or cirrhosis with portal hypertension. - **Kidney palpation** (ballottement): Place your left hand under the left flank, just below the 12th rib. Place your right hand under the left costal margin. Push upward with your left hand, then quickly release and palpate with your right hand. You may feel the kidney "bounce" (ballott). **Costovertebral angle (CVA) tenderness**: Percuss gently over the CVA (where the 12th rib meets the spine, on each side). Tenderness suggests kidney infection (pyelonephritis). **Normal kidney**: nonpalpable in adults unless very enlarged or displaced; tenderness absent. - **Aorta palpation**: Palpate the epigastrium (just above the umbilicus, along the midline) using two fingers (index and middle). You may feel the **aortic pulsation** (normal, especially in lean individuals). **Pulsatile mass >2 cm** suggests **aortic aneurysm**. **DO NOT DEEPLY PALPATE a suspected aneurysm**—aggressive palpation can rupture it, causing massive bleeding and death. If aneurysm is suspected, imaging (CT or ultrasound) is urgent. - **Tenderness in specific regions**: - **RLQ tenderness** → consider appendicitis (McBurney's point is one-third the distance from the ASIS—anterior superior iliac spine—to the umbilicus). **Rovsing's sign** (pain in the RLQ when palpating the LLQ) suggests appendicitis. - **RUQ tenderness** → consider cholecystitis or choledocholithiasis (biliary colic). **Murphy's sign** (inspiratory arrest—patient stops inhaling when you press under the right costal margin)suggests acute cholecystitis. Ask the patient to take a deep breath and hold it while you palpate just below the costal margin; if the inflamed gallbladder touches your hand, the patient feels sharp pain and stops breathing in (positive Murphy's sign). - **Epigastric/LUQ tenderness** → consider gastritis, peptic ulcer, or pancreatic disease. **Cullen's sign** or **Grey Turner's sign** with epigastric pain suggests pancreatitis with bleeding. - **Suprapubic tenderness** → consider urinary tract infection (UTI) or cystitis; assess urinalysis. - **LLQ tenderness** → consider diverticulitis or inflammatory bowel disease (IBD). - **Bladder palpation**: Palpate gently above the pubic symphysis. A **distended bladder** (felt as a rounded, tender mass above the symphysis) suggests urinary retention. The bladder should be nonpalpable after voiding. If distended, assess post-void residual volume (PVR) by catheterization or ultrasound; >100 mL suggests retention. **Abdominal Distention and Ascites:** - **Causes of distention**: **ABDOMEN** mnemonic: **A**ir (gas, obstruction, ileus), **B**owel obstruction, **D**airy/diet (bloating), **O**rganomegaly, **M**ass, **E**nterocolitis, **N** (fluid/ascites). - **Ascites** (peritoneal fluid): Assess for **shifting dullness**, **fluid wave**, **bulging flanks**, and **umbilical protrusion**. Ascites indicates hepatic cirrhosis (most common), heart failure, renal disease, or malignancy. Large ascites can cause respiratory compromise (orthopnea, dyspnea) and abdominal pain. **Special Abdominal Tests:** - **McBurney's point tenderness** → appendicitis. - **Rovsing's sign** (LLQ palpation → RLQ pain) → appendicitis. - **Murphy's sign** (inspiratory arrest on RUQ palpation) → acute cholecystitis. - **Cullen's/Grey Turner's signs** (periumbilical/flank discoloration) + epigastric pain → pancreatitis with bleeding. - **Rebound tenderness** (pain on release after deep palpation) → peritonitis (surgical emergency). - **Rigidity** (board-like, involuntary hardness) → peritonitis or acute abdomen (surgical emergency). **Nursing Implications and NANDA Diagnoses:** - **Acute pain** related to appendicitis, cholecystitis, pancreatitis, or peritonitis; interventions include NPO (nothing by mouth), IV fluids, antibiotics, analgesics, and surgical consultation. - **Risk for fluid volume deficit** related to vomiting, diarrhea, or obstruction; monitor intake/output, electrolytes, and NG tube drainage if present. - **Bowel incontinence** or **constipation** related to obstruction, IBS, or surgical intervention; interventions include dietary modification, laxatives (if not contraindicated), and monitoring bowel movements. - **Malnutrition, risk for** related to inadequate intake from obstruction or GI disease; assess albumin, prealbumin, and nutritional status; consider feeding tube or TPN (total parenteral nutrition) if NPO prolonged. **Red Flags Requiring Immediate Action:** - **Rigid, board-like abdomen with rebound tenderness** → peritonitis; emergency surgery likely needed. - **Severe tenderness + fever + vomiting** → acute abdomen (appendicitis, perforated ulcer, etc.); surgical consultation urgent. - **Pulsatile mass without deeply palpating** → aortic aneurysm; imaging and vascular surgery consultation urgent; never forcefully palpate. - **Absent bowel sounds after listening 5 minutes** → ileus or obstruction; NPO, IV access, labs, imaging (abdominal X-ray, CT if obstruction suspected). - **Absent bowel sounds + severe pain + distention + vomiting** → acute obstruction or peritonitis; emergency intervention required.

Breast and axillary assessment screens for cancer, infection, and hormonal abnormalities. While breast cancer is less prevalent in Filipino populations compared to Western countries, awareness and early detection remain critical, especially given the prevalence of late-stage diagnoses in underserved communities. **Breast Anatomy:** The breast consists of glandular tissue, adipose tissue, and Cooper's ligaments. The **tail of Spence** (also called the axillary tail) extends from the upper outer quadrant toward the axilla. Breast tissue extends from the collarbone superiorly to the inframammary fold inferiorly, and from the sternum medially to the latissimus dorsi laterally. **Inspection:** **Patient positioning:** Inspect with the patient in a **seated position, arms at sides, then with arms raised above the head**. Change in position helps visualize skin changes and breast contour. - **Size and symmetry**: Breasts should be symmetric in size, though mild asymmetry (one breast slightly larger) is common and normal. **Marked asymmetry** or sudden change in size warrants evaluation. Note breast size and shape (rounded, pendulous, etc.). - **Skin**: Should be smooth without dimpling, retraction, or discoloration. Look for: - **Dimpling** or **puckering** → suggests an underlying mass pulling on Cooper's ligaments; may indicate cancer. - **Peau d'orange** (orange-peel texture) → edema from lymphatic obstruction; suggests advanced cancer. - **Redness or warmth** → suggests infection (mastitis) or inflammatory breast cancer. - **Scars** → note location and appearance; distinguish surgical scars from pathology. - **Venous pattern** → may be visible in pale-skinned individuals; become more prominent during pregnancy and lactation. - **Nipples and areolae**: Should be everted (projecting outward) and symmetric in color and position. Note: - **Nipple inversion** → if unilateral and new, may suggest underlying mass; bilateral nipple inversion is often congenital (normal variant). - **Areolar color** → typically brown in light-skinned individuals and darker in darker-skinned individuals; darkening can occur with pregnancy (normal). - **Supernumerary nipples** (extra nipples along the milk line, from sternum to groin) → benign but worth noting. - **Discharge**: Ask about any drainage from the nipple. Spontaneous discharge warrants assessment: - **Bloody or blood-stained** → may indicate intraductal papilloma or cancer; refer for imaging (mammography, ultrasound) and surgical evaluation. - **Clear or milky** (galactorrhea) → suggests hormonal imbalance (hyperprolactinemia); order prolactin level and assess for pregnancy, medications (antipsychotics), or pituitary disease. - **Purulent or foul-smelling** → suggests infection (mastitis, abscess); prescribe antibiotics and advise warm compresses and frequent nursing (if lactating) or manual drainage. **Palpation:** With the patient **supine and one arm behind her head** (to stretch and flatten the breast tissue across the chest wall): - **Gentle palpation**: Use the pads of your fingers (flattened hand or three middle fingers) to systematically palpate the breast. Use a **vertical strip pattern** (starting at the sternum and moving laterally in overlapping strips from superior to inferior) or a **circular pattern** (concentric circles from the periphery toward the nipple). Cover the entire breast, including the tail of Spence and the axilla. - **Normal findings**: Breast tissue should be smooth, firm, and nontender (except possibly slight tenderness 7–10 days before menses due to hormonal changes; this is normal cyclic mastalgia). **Normal breast tissue** may feel granular or nodular, especially in postmenopausal women or with fatty involution; this is often normal fibrocystic change. - **Abnormal findings**: - **Palpable mass** → assess characteristics: size (cm), location (use clock notation: "10 o'clock position, 2 cm from nipple"), consistency (hard, firm, soft), shape (regular, irregular), borders (well-defined, poorly defined), mobility (movable, fixed), and tenderness. A **hard, irregular, poorly defined, fixed, painless mass** is highly suspicious for cancer; refer for imaging and possible biopsy. - **Tender nodules or cysts** → may suggest fibrocystic change (benign); if recurrent or enlarging, ultrasound may help characterize. - **Thickening or dimpling** → may suggest underlying mass. **Axillary Assessment:** - **Palpation**: Have the patient relax her arm. Reach into the axilla with your fingers and gently palpate for lymph nodes (movable, nontender nodes may be normal; firm, fixed, or tender nodes suggest infection or malignancy). - **Nodes**: Grade size and consistency: - **Nonpalpable** → normal. - **Palpable, <1 cm, soft, mobile, nontender** → likely benign (reactive lymphadenopathy from infection or trauma). - **Palpable, >1 cm, firm, fixed, or tender** → suspect malignancy; refer for imaging (chest X-ray, CT) and possible FNA (fine-needle aspiration) or biopsy. **Breast Self-Examination (BSE):** While clinical breast exams by healthcare providers are essential, **monthly BSE** (ideally 7–10 days after menses, when hormonal swelling is minimal) helps women become familiar with their normal breast anatomy. A woman who knows her breasts well is more likely to detect changes early. Encourage patients to: 1. Inspect in a mirror with arms at sides, then raised. 2. Palpate with flattened fingers in all areas, using the three-finger technique or vertical strips. 3. Note any changes in size, shape, color, or the presence of dimpling, discharge, or masses. 4. Report changes to their healthcare provider promptly. **Mammographic Screening (Philippine Context):** In the Philippines, the Department of Health recommends clinical breast examination for all women and mammographic screening starting at age 40 (or based on individual risk). Discuss screening options, importance of early detection, and access to services in local facilities or communities. **Nursing Implications and NANDA Diagnoses:** - **Risk for ineffective health maintenance** related to knowledge deficit about breast health, BSE, or screening; interventions include patient education, demonstration of BSE technique, and provision of educational materials. - **Fear or anxiety** related to breast symptoms or findings suspicious for cancer; provide reassurance, clear explanations, and prompt referral for diagnostic workup. - **Acute pain** related to mastitis or breast abscess; interventions include antibiotics, warm compresses, analgesia, and lactation support (if applicable). - **Altered body image** related to breast surgery or breast reconstruction; provide psychological support and referral to support groups. **Red Flags and When to Refer:** - Any **new, hard, irregular, fixed mass** → refer for imaging and possible biopsy. - **Unilateral nipple inversion** (new) → refer for imaging. - **Bloody or blood-tinged discharge** → refer for imaging and surgical evaluation. - **Signs of infection** (redness, warmth, purulent discharge, fever) → prescribe antibiotics; refer if not improving in 48 hours. - **Suspected inflammatory breast cancer** (rapid onset, peau d'orange, redness) → urgent referral.

The musculoskeletal and neurologic assessments screen for motor function, sensory integrity, reflex responses, cerebellar function, and mental status. These components are critical for identifying stroke, spinal cord injury, peripheral neuropathy, and neuromuscular disorders. **MUSCULOSKELETAL ASSESSMENT:** **Range of Motion (ROM):** Assess **active ROM** (patient moves the joint themselves) and **passive ROM** (you gently move the joint). Compare bilaterally. - **Normal ROM**: Varies by joint; neck should flex/extend 45°, rotate 80° each way. Shoulder should abduct 180°, flex 180°. Hip should flex 120°, abduct 45°. Knee should flex 135°. Ankle should dorsiflex 20° and plantarflex 45°. - **Limited ROM** → may suggest arthritis, contracture (muscle shortening), or pain avoidance. Document the degree of limitation and any pain with movement. - **Hypermobility** → excessive ROM; seen in hypermobility syndromes (Ehlers-Danlos syndrome) and can increase injury risk. **Muscle Strength:** Grade **motor strength** on a **0–5 scale**: - **0** = no contraction (paralysis) - **1** = trace contraction visible/palpable - **2** = weak contraction; movement possible with gravity eliminated - **3** = fair strength; movement against gravity but not against resistance - **4** = good strength; movement against moderate resistance but not full strength - **5** = normal/full strength; movement against full resistance Test major muscle groups: **deltoids** (shoulder abduction), **biceps** (arm flexion), **triceps** (arm extension), **wrist flexors/extensors**, **grip strength** (squeeze your hands firmly), **hip flexors** (raise leg against resistance), **quadriceps** (knee extension), **hamstrings** (knee flexion), **ankle dorsiflexion** (foot upward), **plantarflexion** (foot downward). - **Asymmetric weakness** (one side weaker) → suggests stroke, spinal cord lesion, or peripheral nerve injury; assess for other neurologic signs (facial droop, speech difficulty) to localize the lesion. - **Generalized weakness** (all muscles weak) → suggests neuromuscular disease, severe illness, malnutrition, or deconditioning. **Muscle Mass and Tone:** - **Symmetric muscle mass**: Muscles should be roughly equal on both sides. **Atrophy** (wasting, reduced muscle bulk) suggests disuse, denervation, or chronic illness. - **Muscle tone**: Palpate muscles at rest and during passive motion. Normal tone is firm but relaxed. **Hypotonia** (flaccidity, muscles feel loose/limp) suggests lower-motor-neuron (LMN) disease or spinal shock. **Hypertonia** (increased stiffness) suggests upper-motor-neuron (UMN) disease (stroke, spinal cord injury). **Spasticity** (resistance that gives way suddenly) is a form of hypertonia seen in UMN disease. **Gait and Balance:** - **Observe gait** while the patient walks at a normal pace. Note: - **Symmetry**: Legs should swing equally, arms swing in opposition to legs. - **Speed and rhythm**: Smooth, steady pace. - **Base of support**: Width between feet should be normal (~6–8 inches apart). - **Abnormal gaits**: - **Antalgic gait** (limping, weight shifted away from affected side) → suggests pain in the leg or foot. - **Trendelenburg gait** (hip drops on the unaffected side) → suggests gluteal muscle weakness (hip abductor weakness). - **Steppage gait** (exaggerated hip/knee flexion to clear the foot from the ground) → suggests foot drop (dorsiflexor weakness or peroneal nerve injury). - **Spastic gait** (legs stiff, scissoring action) → suggests UMN disease (cerebral palsy, stroke, spinal cord injury). - **Ataxic gait** (unsteady, broad-based, high-stepping) → suggests cerebellar disease or sensory ataxia (loss of proprioception). - **Parkinsonian gait** (shuffling, stooped, slow) → suggests Parkinson's disease. - **Festinating gait** (progressive speeding up, difficulty stopping) → also seen in Parkinson's disease. - **Balance (Romberg test)**: Ask the patient to stand with feet together, eyes open, then eyes closed. Normally, they remain steady. **Positive Romberg** (patient falls or sways significantly with eyes closed) suggests loss of proprioception (posterior column disease) or vestibular dysfunction; do not allow the patient to fall—stand close and be ready to catch them. - **Tandem gait** (walking heel-to-toe in a straight line): Tests cerebellar function and balance. Inability to walk the line suggests cerebellar ataxia. **Joints:** - **Inspect** for redness, warmth, swelling (effusion), or deformity (rheumatoid deformities, Heberden's nodes). - **Palpate** for tenderness, warmth (suggests inflammation), swelling, or crepitus (grinding sensation due to bone-on-bone friction). - **Specific joint assessment**: - **Knees**: Check for **McMurray's sign** (pain with twisting a bent knee, suggesting meniscal tear) and **anterior/posterior drawer tests** (assess stability of the ligaments). - **Shoulders**: Assess for **impingement pain** (pain when arm is passively flexed across the chest). --- **NEUROLOGIC ASSESSMENT:** **Level of Consciousness (LOC) – Glasgow Coma Scale (GCS):** The **GCS** quantifies consciousness on a scale of **3–15** (3 = unconscious, 15 = fully alert). It has three components: 1. **Eye Opening (E)**: 1–4 points - **4** = spontaneous (eyes open without stimulus) - **3** = opens to verbal command - **2** = opens to pain - **1** = no response 2. **Verbal Response (V)**: 1–5 points - **5** = oriented (person, place, time, situation) - **4** = confused (disoriented) - **3** = inappropriate words (rambling, not coherent) - **2** = incomprehensible sounds (groaning) - **1** = no response 3. **Motor Response (M)**: 1–6 points - **6** = obeys commands - **5** = localizes pain (reaches toward painful stimulus) - **4** = withdraws from pain (reflexive withdrawal) - **3** = abnormal flexion (decorticate posture—arms flexed, legs extended) - **2** = abnormal extension (decerebrate posture—arms and legs extended) - **1** = no response **Total GCS = E + V + M** - **GCS 15** = fully alert and oriented. - **GCS 13–14** = mild altered consciousness (mild concussion, intoxication). - **GCS 9–12** = moderate altered consciousness (severe head injury, metabolic encephalopathy). - **GCS ≤8** = severe altered consciousness/coma; **airway protection needed**—consider intubation. **Clinical Implication**: Monitor GCS serially; **trending downward** indicates worsening condition and possible increased intracranial pressure (ICP)—notify physician immediately. **Orientation (Part of Verbal Response):** Test orientation to **person** (name, who they are), **place** (where are they), **time** (date, day, month, year). - **Fully oriented** (alert and oriented x 3 or AO x 3): knows person, place, time. - **Disoriented**: may be confused to place/time ("I think I'm at home, but I'm not sure what day it is"), or person (calling the nurse by their relative's name). **Acute disorientation** (delirium) is different from chronic disorientation (dementia); delirium is a medical emergency suggesting infection, metabolic derangement, hypoxemia, or drug effect. **Cranial Nerves (CN I–XII):** Most cranial nerves are tested during the head-to-toe exam. A quick screening: - **CN I (Olfactory)**: Ask patient to smell coffee, peppermint, or alcohol on a cotton ball; rarely tested in acute settings. - **CN II (Optic)**: Visual acuity, visual fields (ask patient to count fingers in each quadrant or note when you move a finger into their field), optic disc appearance (normal, pale, or swollen). - **CN III, IV, VI (Oculomotor, Trochlear, Abducens)**: Extraocular movements in six cardinal directions; pupil size and reactivity; ptosis. - **CN V (Trigeminal)**: Facial sensation (touch forehead, cheek, jaw with cotton ball or pin; patient should feel it); corneal reflex (light touch to cornea should elicit blink). - **CN VII (Facial)**: Facial symmetry, smile, eye closure, frown; any droop? - **CN VIII (Vestibulocochlear)**: Hearing (whisper test, Weber, Rinne). - **CN IX, X (Glossopharyngeal, Vagus)**: Gag reflex, swallowing, "ahhh" test (uvula elevation and midline), swallowing water (note any coughing or difficulty). - **CN XI (Accessory)**: Shoulder shrug against resistance, head turn against resistance (sternocleidomastoid). - **CN XII (Hypoglossal)**: Tongue protrusion (should be midline); note any fasciculations (muscle twitching) or deviation. **Sensory Assessment:** - **Light touch**: Use a soft cotton ball or your fingertip; ask "can you feel that?" Assess all extremities and compare bilaterally. **Decreased sensation** (patient cannot feel light touch) suggests peripheral neuropathy, spinal cord lesion, or thalamic stroke. - **Pain** (pinprick): Use a disposable pin (never reuse); prick gently and ask "is that sharp?" Note if pain sensation is normal, diminished, or absent. **Dissociated sensory loss** (loss of pain/temperature but preserved touch) suggests syringomyelia or thalamic stroke. - **Vibration sense**: Place a vibrating tuning fork on a bony prominence (ankle, knee, elbow, wrist) and ask "can you feel the buzzing?" Normal is vibration sense throughout. **Decreased vibration sense** (especially in feet/legs distally before hands) is common in diabetic neuropathy. - **Proprioception** (position sense): Hold the patient's finger or toe and move it up/down; ask "which way is my finger pointing?" Patient should know without looking. **Loss of proprioception** causes sensory ataxia (unsteady gait, Romberg positive, eyes-closed walking impaired). - **Stereognosis** (object recognition by touch): Place a familiar object (coin, key, paperclip) in the patient's hand (eyes closed) and ask them to identify it. **Inability to recognize** suggests cortical sensory loss (parietal lobe lesion). **Deep Tendon Reflexes (DTR):** Grade reflexes on a **0–4+ scale** (or 0–3+; systems vary): - **0** = absent (no response) - **1+** = sluggish or diminished - **2+** = normal (brisk, responsive) - **3+** = hyperactive (more brisk than normal, possible clonus) - **4+** = hyperactive with clonus (rhythmic bouncing after the initial response) **Normal reflex is 2+.** Test major reflexes: - **Biceps reflex** (C5–C6): Tap biceps tendon at the elbow; biceps flexes. - **Triceps reflex** (C7–C8): Tap triceps tendon on the back of the upper arm; triceps extends. - **Patellar reflex** (L3–L4): Tap patellar tendon just below the kneecap; leg extends at the knee. - **Achilles reflex** (S1–S2): Tap Achilles tendon at the ankle; foot plantarflexes. **Abnormal reflexes:** - **Hyperactive (3+, 4+)** → suggests upper-motor-neuron (UMN) disease (stroke, spinal cord compression). - **Absent (0)** → suggests lower-motor-neuron (LMN) disease (peripheral neuropathy, cauda equina syndrome) or spinal shock (immediately after spinal cord injury). - **Asymmetric** (one side hyperactive, one side diminished) → suggests focal neurologic lesion on the side of hyperactivity. **Clonus** (rhythmic bouncing): Hold the ankle and abruptly dorsiflex the foot; if you feel rhythmic plantarflexion and dorsiflexion (bouncing), **clonus** is present. Indicates UMN disease; **sustained clonus** (>3 bounces) suggests severe UMN disease. **Plantar Reflex (Babinski Sign):** Using a blunt object (stick, key, or end of a reflex hammer), stroke the lateral aspect of the sole of the foot, moving toward the toe. Normal response: toes **curl downward** (plantarflexion, flexor response). **Abnormal response** (Babinski sign, extensor response): **toes fan outward and big toe extends upward**. - **Normal in adults**: flexor response (toes down). - **Abnormal in adults**: extensor response (Babinski)—indicates **upper-motor-neuron disease** (stroke, spinal cord injury, brain tumor). This is a critical finding. - **Normal in infants** (until ~12 months): Babinski is normal (immature nervous system); myelination completes and response becomes flexor by age 12–18 months. **Coordination (Cerebellar Function):** - **Finger-to-nose test**: Ask patient to touch their nose with their index finger, then touch your finger (held at arm's length away). Repeat several times, moving your finger around. Normal: smooth, accurate movement. **Dysmetria** (overshooting or undershooting the target): suggests cerebellar disease. - **Rapid alternating movements (RAM)** (dysdiadochokinesia if abnormal): Ask patient to tap their thigh rapidly with alternating sides of the hand (or pronate/supinate forearms rapidly). **Slow, clumsy, or arrhythmic movements** suggest cerebellar disease. - **Heel-to-shin test**: Ask patient to place their heel on their opposite knee and run it down to the ankle. Movement should be smooth. **Jerky, inaccurate movement** suggests cerebellar ataxia. **Mental Status (Beyond LOC and Orientation):** - **Appearance**: Well-groomed or disheveled? Alert and appropriate for setting? - **Behavior**: Cooperative, agitated, withdrawn, or inappropriate? - **Speech**: Clear, coherent, rapid, slurred, or dysphagic (difficulty speaking)? - **Mood and affect**: Happy, sad, anxious, angry, flat (blunted)? Congruent with content? - **Cognition**: Can they perform simple calculations, recall three objects, or spell "world" backwards? **Cognitive impairment** may suggest delirium, dementia, or psychiatric condition. - **Insight and judgment**: Do they understand their condition and make appropriate decisions? **Lack of insight** may suggest anosognosia (after stroke) or psychiatric illness. **Nursing Implications and NANDA Diagnoses:** - **Impaired physical mobility** related to weakness, pain, or neurologic deficit; interventions include physical therapy, range-of-motion exercises, assistive devices, and fall prevention. - **Risk for falls** related to gait instability, weakness, or balance impairment; interventions include safety precautions (remove clutter, adequate lighting, bed rail), supervised ambulation, and assessment for assistive devices (cane, walker). - **Impaired communication** related to aphasia (difficulty expressing or understanding speech) or dysarthria (difficulty articulating); interventions include simplified language, written communication, and speech therapy. - **Risk for injury** related to sensory loss, decreased LOC, or seizure activity; interventions include environmental modification, supervision, padded side rails (if seizure risk), and seizure precautions. - **Acute confusion** (delirium) related to infection, metabolic derangement, hypoxemia, or medication; interventions include identification and treatment of the underlying cause, reorientation, safe environment, and monitoring. **Red Flags and When to Notify Physician Immediately:** - **Declining GCS** (decreasing by 2 or more points) → possible increased ICP; prepare for possible intubation. - **Unilateral dilated, non-reactive pupil** → possible brain herniation; neurologic emergency. - **New focal neurologic deficit** (weakness, facial droop, vision loss, speech difficulty) → possible stroke; activate stroke alert. - **Seizure activity** → protect patient from injury, note duration and type of seizure, prepare anti-seizure medications. - **Loss of gag reflex or difficulty swallowing** → aspiration risk; implement precautions (NPO, elevated head, feeding assistance). - **Absence of spontaneous motor activity or responsiveness** → assess for spinal cord injury; immobilize cervical spine if trauma suspected.
