Important facts
- Always compare bilateral structures for symmetry; asymmetry is abnormal.
- Modified abdominal sequence: Inspect → Auscultate → Percuss → Palpate (prevents palpation/percussion from altering bowel sounds).
- Maintain privacy, warmth, and standard precautions; expose only the area being examined.
- Warm hands and stethoscope before contact to reduce client discomfort and ensure accurate findings.
- Group techniques to minimize position changes; ask client to void before abdominal assessment.
- General survey and vital signs are always first — establish baseline LOC, general appearance, and health status.
Key definitions
IPPA Technique
Example
When assessing the lungs, you inspect for symmetry, palpate for fremitus, percuss for resonance, then auscultate for breath sounds.
Inspection, Palpation, Percussion, Auscultation — the four hands-on assessment methods applied systematically to gather objective data.
Cephalocaudal Approach
Example
Begin at the head (mental status, HEENT), move to neck/thorax, heart, lungs, breasts, abdomen, extremities, and end with neurologic and gait assessment.
Head-to-toe assessment order that ensures systematic coverage, minimizes position changes, and conserves client energy.
Bilateral Symmetry
Example
Compare pupil size, facial muscle movement, breath sounds, pulse quality, and limb strength on both sides.
Comparison of left and right sides of the body to detect asymmetry, which often signals pathology.

Clubbed nail-bed angle
Important facts
- Normal skin: warm, dry, intact, even color for ethnicity; good turgor; immediate capillary refill.
- Cyanosis (central) — lips, tongue, mucous membranes — is a sign of hypoxemia and requires immediate assessment of ABCs.
- Pallor (pale, blanched appearance) may indicate anemia, shock, or vasoconstriction.
- Jaundice (yellow discoloration of sclera and skin) signals hyperbilirubinemia; always abnormal.
- Edema graded 1+ to 4+: 1+ (slight, ~2 mm, rapid rebound), 4+ (deep, ~8 mm, prolonged rebound); note unilateral vs. bilateral.
- Reduced capillary refill, poor turgor, and cool/clammy skin = poor perfusion; assess further for shock.
Key definitions
Capillary Refill
Example
Press the client's fingernail to blanch, release, and count seconds until pink returns. >3 sec = hypoperfusion, possible shock.
Time for color to return to nail bed after blanching; normal is <2–3 seconds; delayed refill signals poor perfusion.
Skin Turgor
Example
In elderly or dehydrated clients, pinched skin remains 'tented' rather than returning promptly to flat.
Elasticity of skin; pinch skin on forearm and observe how quickly it recoils. Immediate recoil = normal; slow recoil/tenting = dehydration.
Clubbing
Example
Normal angle ~160°; clubbed nails appear bulbous and rounded at the fingertip.
Nail-bed angle increases to 180° or greater, indicating chronic hypoxia; associated with cyanotic heart disease, COPD, lung cancer.

Head, Face, Neck & Lymphatics
Important facts
- Normal head: normocephalic, symmetric; face symmetric with intact CN VII movement (no droop).
- Trachea should be midline; palpate just below the Adam's apple to confirm.
- Thyroid: nonpalpable or small, smooth, and moves with swallowing; hard, fixed, or nodular = abnormal.
- Lymph nodes: normally nonpalpable or small, soft, nontender; hard, fixed, or tender nodes suggest infection or malignancy.
- CN VII (facial) assessment: ask client to smile, raise eyebrows, puff cheeks, and close eyes tightly; look for symmetry.
- A single hard, fixed lymph node is a red flag for malignancy; refer immediately.
Key definitions
Normocephalic
Example
A healthy adult has a rounded, evenly proportioned skull.
Head shape is normal, symmetric, without abnormal bumps, flattening, or masses.
Facial Droop
Example
One side of the face appears flat, smile is crooked, eye closes incompletely — part of the FAST stroke screen.
Asymmetry of facial muscles, often due to CN VII palsy (Bell's palsy) or stroke; assessed by asking client to smile, raise eyebrows, and puff cheeks.
Tracheal Deviation
Example
Palpate the thyroid notch and feel whether the trachea is centered; any deviation is abnormal and requires investigation.
Trachea shifted from midline; may indicate tension pneumothorax (emergency), mass, or thyroid enlargement.

Quantity
Normal visual acuity
Important facts
- Normal pupils: PERRLA; 3–5 mm; equal bilaterally.
- Fixed, dilated pupil (>5 mm, no response to light) = neurologic emergency (increased ICP, CN III palsy, brainstem death); report immediately.
- Pinpoint pupils (<2 mm, reactive) suggest opioid intoxication or pontine hemorrhage.
- Ptosis (drooping eyelid) = CN III involvement or myasthenia gravis.
- Normal tympanic membrane: pearly gray, intact, light reflex present, landmarks visible.
- Red or bulging tympanum = otitis media; purulent discharge = possible perforation; hearing loss on whisper test = abnormal.
- Nasal septum should be midline; uvula rises midline on phonation ('ahh'); gag reflex (CN IX/X) should be present.
- Enlarged/exudative tonsils with fever = pharyngitis; uvula deviation (CN X damage) = abnormal.
Key definitions
PERRLA
Example
Shine a penlight into one eye; the pupil should constrict and the opposite pupil should also constrict (consensual reflex).
Pupils Equal, Round, Reactive to Light and Accommodation; normal pupils are 3–5 mm, symmetric, and respond to light by constricting and to near vision by constricting and converging.
Anisocoria
Example
One pupil 5 mm and reactive, the other 3 mm and reactive = physiologic anisocoria (common, benign); but a fixed 5 mm pupil = emergency.
Unequal pupil size; if >1 mm difference and fixed/dilated on one side, consider Horner syndrome, CN III palsy, or intracranial pathology.
Icteric Sclera
Example
In hepatic disease or hemolysis, the sclera appear yellow-tinged rather than white.
Yellow discoloration of the sclera (whites of the eyes) indicating jaundice and hyperbilirubinemia; always abnormal.

Important facts
- Normal RR: 12–20 breaths/min, unlabored, symmetric chest expansion.
- AP-to-transverse chest ratio normally ~1:2; if 1:1 = barrel chest (COPD, emphysema).
- Percussion: resonance over normal lung, dullness over consolidated/fluid-filled areas, hyperresonance over air-trapped areas.
- Stridor (high-pitched inspiratory sound) = upper-airway obstruction; EMERGENCY — assess immediately for airway compromise.
- Absent/severely diminished breath sounds over one side = pneumothorax, hemothorax, pleural effusion, or severe consolidation; investigate promptly.
- Pleural friction rub (grating sound) = inflamed pleura; associated with pleurisy.
- In a client with low SpO2 or dyspnea, assess for adventitious sounds and work of breathing (retractions, use of accessory muscles).
- Central cyanosis (lips, tongue) = hypoxemia; this is a red flag — check SpO2, assess ABCs, and report immediately.
Key definitions
Vesicular Breath Sounds
Example
Listen at the lung bases and apices away from the trachea; this is your baseline normal.
Soft, low-pitched, whooshing sound heard over most of the lung periphery; normal finding; indicates air moving through small airways.
Bronchovesicular Breath Sounds
Example
Heard around the sternal notch and lower neck; medium volume compared to vesicular.
Intermediate pitch and intensity; normal over the main bronchi (1st and 2nd ICS, sternal border and between scapulae).
Bronchial Breath Sounds
Example
Listen at the trachea above the sternal notch; this is where bronchial sounds belong.
Loud, high-pitched, hollow, tubular sound; normal over the trachea; if heard over lung periphery = consolidation (abnormal).
Crackles (Rales)
Example
Fine crackles (end-inspiration) in basilar lung fields = heart failure; coarse crackles = pneumonia.
Discontinuous, brief popping/crackling sounds; indicate fluid in alveoli or small airway reopening; heard in pneumonia, heart failure, interstitial lung disease.
Wheezes
Example
Polyphonic wheezes (multiple pitches) = small airway disease; monophonic (single pitch) = single airway obstruction.
Continuous, high-pitched, musical sounds; indicate narrowed airways; heard in asthma, COPD, anaphylaxis.
Rhonchi
Example
Heard in bronchitis or when a client has copious mucus; listen before and after cough.
Low-pitched, snoring-like continuous sound; indicate secretions in larger airways; may clear with cough.

Pulse
Quantity
Normal pulse grading
Important facts
- Normal apical pulse: 60–100 bpm, regular rhythm, located at 5th ICS left midclavicular line.
- Auscultation sequence (APE To Man): Aortic (2nd right ICS) → Pulmonic (2nd left ICS) → Erb's point (3rd left ICS) → Tricuspid (4th left ICS) → Mitral/apex (5th ICS MCL).
- S1 loudest at apex; S2 loudest at base; listen for the lub-dub rhythm.
- Irregular rhythm = arrhythmia; assess further with ECG; report palpitations or syncope.
- Normal peripheral pulses: present, symmetric, strong (2+), regular, no bruits, warm extremities, good capillary refill.
- Diminished/absent pulses, coolness, pallor = arterial insufficiency; assess for claudication, pain.
- Bilateral edema = systemic cause (heart failure, liver disease, hypoalbuminemia); unilateral edema = local cause (DVT, lymphedema).
- Pitting edema 1+ = minimal, rapid rebound; 4+ = severe, prolonged rebound; document location and symmetry.
- Bruits (whooshing sound) = turbulent flow, suggests vascular narrowing; abnormal finding — refer for vascular workup.
- CVP distention (jugular venous pressure visibly elevated) = right heart failure, volume overload, or pulmonary hypertension.
Key definitions
PMI (Point of Maximal Impulse)
Example
A displaced PMI (outside midclavicular line or >5th ICS) suggests cardiomegaly.
The apical pulse location; normally at the 5th intercostal space, midclavicular line, left side; diameter ~1–2 cm.
S1 Heart Sound
Example
Auscultate at the 5th ICS midclavicular line; should sound like a single 'lub'; if split, suggests abnormality.
First heart sound ('lub'); closure of atrioventricular (mitral and tricuspid) valves; loudest at the apex.
S2 Heart Sound
Example
Normally single; physiologic split (S2 splits into A2 and P2 during inspiration) is normal in young people.
Second heart sound ('dub'); closure of semilunar (aortic and pulmonic) valves; loudest at the base (right upper sternal border).
S3 Gallop
Example
In an adult with dyspnea and S3, consider acute heart failure; in a healthy 20-year-old, S3 may be benign.
Third heart sound (ventricular gallop); low-pitched, heard early in diastole; normal in children and young adults, but pathologic in older adults — suggests heart failure, fluid overload, or decreased ventricular compliance.
S4 Gallop
Example
Rhythmic 'lub-a-dub' pattern; use bell of stethoscope to hear low-frequency S4.
Fourth heart sound (atrial gallop); heard late in diastole; indicates stiff ventricle or decreased ventricular compliance; associated with hypertension, MI, or cardiomyopathy.
Heart Murmur
Example
A new systolic murmur at the apex = possible mitral regurgitation; requires further evaluation.
Abnormal turbulent flow sound; characterized by timing (systolic/diastolic), grade (1–6), quality (blowing, harsh, musical), and radiation; requires echocardiography for diagnosis.
Pulse Grading
Example
In shock, pulses may be 1+ and thread-like; in septic shock, they may be 3+ and bounding initially.
0 = absent, 1+ = weak/diminished, 2+ = normal (brisk, expected), 3+ = hyperdynamic, bounding.

Value
6–12 cm
Symbol
LS
Quantity
Normal liver span (MCL)
Important facts
- Modified sequence: Inspect → Auscultate → Percuss → Palpate (do NOT palpate first, as it alters bowel sounds).
- Normal abdomen: flat or slightly rounded, symmetric, no visible peristalsis/pulsations, soft, nontender.
- Bowel sounds: normal 5–30/min; listen in all four quadrants; listen ≥5 minutes before charting 'absent.'
- Percussion: tympany over most of abdomen; dullness over solid organs (liver, spleen) and full bladder.
- Normal liver span (right midclavicular line): 6–12 cm; not normally felt below the rib margin.
- Palpable, pulsatile mass = possible aortic aneurysm; DO NOT palpate deeply — this is an emergency.
- Rigid abdomen ('board-like') with rebound = peritonitis; emergency — report immediately, prepare for imaging/surgery.
- Distention (swollen appearance), visible veins, absent bowel sounds = possible obstruction or ileus.
- Bruits (vascular sounds) = narrowing; abnormal.
- Always ask: Last bowel movement? Constipation, diarrhea, blood in stool?
Key definitions
Bowel Sounds
Example
Count for a full minute in one quadrant; if absent in all four quadrants after listening for 5 minutes, chart as 'absent' (suggests ileus).
Gurgling/clicking sounds from intestinal peristalsis; normal frequency 5–30/min in all four quadrants; present after eating or in response to stimulation.
Hyperactive Bowel Sounds
Example
In early bowel obstruction, sounds are loud and frequent; as obstruction progresses, they become absent.
Frequent, high-pitched, tinkling sounds (>30/min); seen in early mechanical obstruction, diarrhea, or gastroenteritis.
Hypoactive Bowel Sounds
Example
After abdominal surgery, hypoactive sounds are expected for the first 24–48 hours; return of flatus indicates return of function.
Diminished or infrequent sounds (<5/min); suggest ileus, peritonitis, or post-surgical state.
Rebound Tenderness
Example
Slowly press into the abdomen, then quickly release; if pain is worse on release than on pressure, document as positive rebound.
Sharp pain when the examiner rapidly releases pressure on palpation; indicates peritoneal irritation/inflammation; seen in peritonitis, appendicitis, perforation.

Breasts & Axillae
Important facts
- Normal breast findings: symmetric (mild asymmetry okay), smooth skin without dimpling, everted or symmetric nipples, no masses, no tenderness, no discharge.
- Red flags: fixed hard mass, skin dimpling or peau d'orange, nipple retraction, spontaneous/bloody discharge, and enlarged axillary lymph nodes.
- Axillary nodes normally nonpalpable; if palpable: note size (cm), consistency, mobility, tenderness, and number.
- Hard, fixed, irregular, painless mass = high suspicion for malignancy; refer immediately.
- Spontaneous discharge (especially if bloody or from one duct) = abnormal; document color, consistency, and refer.
- Reinforce monthly breast self-examination (BSE) and age-appropriate screening mammography (PH guidelines: annual ≥40 years, or earlier if risk factors).
- Gynecomastia (male breast enlargement) may be normal (puberty, certain drugs) or pathologic (liver disease, hormone excess).
- Mastalgia (breast pain) often cyclical and benign but requires assessment to rule out abscess, malignancy, or hormonal disorder.
Key definitions
Breast Symmetry
Example
A woman with one breast slightly smaller than the other is normal; but a sudden new asymmetry or size change warrants investigation.
Left and right breasts should be similar in size and shape; mild asymmetry is common and normal.
Peau d'Orange
Example
On inspection, the skin appears dimpled and thickened, like an orange peel; always abnormal and requires urgent referral.
Orange-peel texture of breast skin; indicates superficial edema from lymphatic obstruction; classic sign of advanced breast cancer.
Nipple Retraction
Example
A woman who previously had everted nipples now shows one inverted = red flag; needs imaging and clinical follow-up.
Inward turning/inversion of the nipple; if new or unilateral, suggests malignancy; if long-standing and bilateral, may be congenital.

Hip flexion ROM
Important facts
- Normal findings: full ROM all joints, symmetric muscle mass and strength (5/5 bilaterally), steady gait, no deformities.
- Assess ROM active (client-initiated) then passive (examiner-assisted); passive ROM > active suggests pain or weakness limiting active movement.
- Document asymmetric weakness (one limb <5/5 vs. other) — suggests focal lesion (CVA, nerve damage) and requires imaging.
- Edema, swelling, erythema, warmth over joint = inflammation; assess for fever, limited ROM, pain (suggestive of septic joint, rheumatoid arthritis).
- Atrophy (wasting of muscle) suggests chronic disuse, neurologic disease, or malignancy.
- Tremor (rhythmic involuntary movement) may be resting (Parkinson's), postural, or intentional; document amplitude and pattern.
- Gait assessment: watch for symmetry, stride length, balance, steadiness; Trendelenburg (hip drop on swing phase) = hip weakness.
- Postural hypotension (dizziness on standing) may contribute to fall risk; assess stability and assist as needed.
- Joint contracture (fixed, limited ROM) = chronic immobility; prevention is key in NCM practice.
Key definitions
Range of Motion (ROM)
Example
Ask client to move the joint through its normal range; compare bilateral joints; limited ROM = joint disease, inflammation, or contracture.
Extent of movement at a joint; measured in degrees; normal ROM varies by joint (e.g., shoulder abduction 180°, hip flexion 120°).
Muscle Strength Grading (0–5 Scale)
Example
Compare bilateral limbs; if one side is 4/5 and the other 5/5, this is asymmetric weakness and may suggest stroke or nerve damage.
0 = no contraction, 1 = trace, 2 = weak, 3 = fair (against gravity), 4 = good (against gravity and mild resistance), 5 = normal (full strength against full resistance).
Crepitus
Example
Client with knee osteoarthritis reports crepitus when bending; subcutaneous emphysema (pneumothorax) produces crepitus under the skin.
Grating, crackling sensation or sound felt/heard over a joint or tendon; suggests cartilage degeneration, air in tissues (subcutaneous emphysema), or fractured bone.

- Declining LOC = medical emergency; assess for shock, hypoxia, hypoglycemia, intracranial pressure, intoxication.
- FAST screen for stroke: Face (droop), Arm (drift/weakness), Speech (slurred), Time (call EMS immediately if positive).
- Fixed, dilated pupil = CN III palsy or increased ICP; pupil <2 mm and reactive = opioid effect or pontine damage.
- Normal DTRs 2+; absent DTRs = peripheral nerve damage; hyperactive/clonus = upper-motor-neuron lesion.
- Positive Babinski (toes fan) in adult = abnormal; upper-motor-neuron disease (stroke, spinal cord).
- Positive Romberg (swaying/falling with eyes closed) = proprioceptive or vestibular dysfunction.
- Confusion/disorientation, memory loss, mood changes = assess for delirium (acute, fluctuating) vs. dementia (chronic, progressive) vs. psychiatric disorder.
- Meningeal signs: nuchal rigidity (neck stiffness) + fever + headache = meningitis; EMERGENCY.
- Tremor, rigidity, bradykinesia = Parkinson's; hyperreflexia + clonus + Babinski = pyramidal tract lesion.
Key definitions
Glasgow Coma Scale (GCS)
Example
A client opens eyes to pain (E=2), is confused (V=4), localizes to pain (M=5) = GCS 11 (moderate brain injury).
Standardized 15-point scale assessing level of consciousness (LOC): Eye Opening (4), Verbal Response (5), Motor Response (6); GCS 15 = fully alert, GCS ≤8 = coma (consider airway protection).
Pupil Reactivity
Example
One pupil reacts normally to light, the other remains 5 mm and does NOT constrict = emergency; report immediately.
Response of pupils to light (brisk constriction = normal); a fixed, dilated pupil (no response to light) = neurologic emergency (increased ICP, CN III damage).
Deep Tendon Reflex (DTR) Grading
Example
Tap the patellar tendon; normal response is a brief knee jerk; absent reflex (0) suggests nerve damage; brisk with clonus (4+) suggests upper-motor-neuron lesion.
0 = absent, 1+ = hypoactive (diminished), 2+ = normal (brisk), 3+ = hyperactive, 4+ = hyperactive with clonus; normal is 2+.
Babinski Sign
Example
Stroke down lateral foot sole from heel toward toes; normal adult: toes flex/curl downward; abnormal (positive Babinski): toes fan/extend upward.
Upward fanning of toes when sole of foot is stroked; normal in infants <12 months; abnormal in adults — indicates upper-motor-neuron lesion (stroke, spinal cord injury).
Cranial Nerve (CN)
Example
Client with facial droop and loss of nasolabial fold = CN VII (facial) damage; loss of gag reflex = CN IX/X (glossopharyngeal/vagus).
Twelve pairs of nerves serving head and neck; assessed systematically (CN II optic → vision/visual fields; CN III oculomotor, CN IV trochlear, CN VI abducens → eye movement; CN V trigeminal → facial sensation; CN VII facial → facial movement; CN VIII vestibulocochlear → hearing; CN IX glossopharyngeal, CN X vagus → gag/swallow; CN XI accessory → shoulder/neck; CN XII hypoglossal → tongue).

Important facts
- Normal urinalysis: clear, yellow to amber, specific gravity 1.010–1.030, pH 4.5–8, no protein/glucose/RBCs/WBCs.
- Cloudy urine or pyuria (WBCs in urine) = UTI; nitrites and leukocyte esterase on dipstick = presumed UTI.
- Proteinuria (persistent protein in urine) = glomerular disease, nephrotic syndrome, or diabetic nephropathy.
- Glycosuria = hyperglycemia or renal threshold exceeded; assess for diabetes.
- Monitor I&O: accurate intake and output records are essential for fluid balance assessment and determining AKI/CKD.
- Catheterized client: assess for signs of infection (cloudy urine, WBCs, fever), proper drainage, and secure anchoring.
- External genitalia: assess for lesions, abnormal discharge, signs of STI, or trauma.
- Normal inguinal lymph nodes nonpalpable; palpable, tender nodes = local infection; hard, fixed nodes = malignancy.
- Bladder distention (tenderness above symphysis pubis, dullness on percussion) = urinary retention; assess for cause (obstruction, medication, neurologic).
- In post-op clients, monitor for void within 6–8 hours; inability to void = retention; catheterize per protocol.
Key definitions
Urine Output
Example
A 70-kg adult should produce ~35–70 mL/hr; if producing <20 mL/hr, investigate for dehydration, obstruction, or renal failure.
Normal adult output ~0.5–1 mL/kg/hr (~1500 mL/day); oliguria <400 mL/day; anuria <100 mL/day or none.
Hematuria
Example
Gross hematuria + flank pain = likely kidney stone; hematuria without pain = investigate for cancer, especially in smokers.
Blood in urine; can be gross (visible, dark/cola-colored) or microscopic; indicates urinary tract infection, stones, malignancy, glomerulonephritis, or trauma.
Dysuria
Example
Young woman with dysuria, frequency, urgency, and suprapubic tenderness = cystitis; needs urinalysis and culture.
Painful urination; often accompanies UTI; client reports burning, frequency, urgency.

Red Flags & Priorities — ABC Framework
Important facts
- Stridor (upper-airway obstruction) = emergency; secure airway, prepare for intubation.
- Central cyanosis = hypoxemia; check SpO2, give O2, assess for respiratory/cardiac cause.
- Absent breath sounds on one side + acute dyspnea + tachycardia = pneumothorax until proven otherwise; chest X-ray stat.
- Fixed, dilated pupil + headache = increased ICP; neurosurgical emergency.
- Sudden facial droop + slurred speech + arm drift = stroke; use FAST, call EMS, note time of onset (thrombolytic window).
- Rigid abdomen + rebound tenderness + fever = acute abdomen/peritonitis; surgical emergency.
- Severe chest pain + diaphoresis + dyspnea = ACS; obtain 12-lead ECG, troponin, call cardiology.
- Unresponsiveness + no breath sounds + no pulse = cardiac arrest; initiate CPR per BLS protocol.
- Shock (hypotension + tachycardia + altered LOC + poor perfusion) = medical emergency; establish IV access, fluids, vasopressors as needed.
Key definitions
ABC Priority
Example
Client with stridor and cyanosis = airway emergency; secure airway before assessing anything else.
Assess in order: Airway (patent, no obstruction), Breathing (adequate rate/depth, SpO2 ≥90%), Circulation (pulse, BP, perfusion); address life threats first.
Stridor
Example
Child with croup (viral laryngitis) or adult with anaphylaxis presenting with stridor = prepare for airway intervention.
High-pitched inspiratory sound indicating upper-airway obstruction; EMERGENCY until proven otherwise.
Central Cyanosis
Example
Newborn or child with cyanotic congenital heart disease showing persistent central cyanosis and SpO2 <88% = emergency.
Blue discoloration of lips, tongue, mucous membranes (not nail beds/extremities); indicates hypoxemia (SpO2 <85–90%); EMERGENCY.

- Red flag findings decision tree
Must remember
- IPPA sequence is the foundation: Inspect → Palpate → Percuss → Auscultate. Exception: ABDOMEN = Inspect → Auscultate → Percuss → Palpate (never palpate first in abdomen).
- PERRLA = pupils Equal, Round, Reactive to Light, Accommodation. A fixed dilated pupil (>5 mm, no light response) is a neurologic emergency; pinpoint pupils suggest opioids. Compare pupils bilaterally — anisocoria >1 mm may be abnormal.
- Breath sounds: Vesicular (normal periphery) → Bronchovesicular (main bronchi) → Bronchial (over trachea). Crackles = fluid (pneumonia, HF), wheezes = narrow airways (asthma, COPD), stridor = upper-airway emergency. Absent breath sounds = pneumothorax, effusion, or severe consolidation.
- Auscultate heart in order APE To Man: Aortic (2nd right ICS) → Pulmonic (2nd left ICS) → Erb's (3rd left ICS) → Tricuspid (4th left ICS) → Mitral/Apex (5th ICS MCL). S1 loudest at apex (AV valve closure); S2 loudest at base (semilunar valve closure). S3 in adults = heart failure/fluid; S4 = stiff ventricle.
- Abdomen: Normal bowel sounds 5–30/min (listen ≥5 min before charting absent). Modified sequence: Inspect → Auscultate → Percuss → Palpate. Never palpate a pulsatile mass (possible AAA — call surgeon). Rebound tenderness + rigidity + fever = peritonitis emergency.
- Neurologic: GCS 15 = fully alert, ≤8 = coma (airway risk). FAST screen = Face droop, Arm drift, Speech slurred, Time (call EMS). Normal DTRs = 2+ (0–4+ scale); absent = nerve damage; ≥3+ with clonus = upper-motor-neuron lesion. Positive Babinski (toes fan) in adult = abnormal (stroke, spinal cord).
- Red flags requiring immediate ABC assessment & report: Stridor, absent/severely diminished breath sounds, SpO2 <90% or central cyanosis, fixed dilated pupil, sudden facial droop/slurred speech, absent peripheral pulses with cool mottled limb, rigid abdomen with rebound, unresponsiveness.
- Capillary refill normal <2–3 sec (poor perfusion if delayed). Skin turgor: pinched skin recoils immediately (normal) vs. tenting (dehydration). Edema graded 1+ (slight, rapid rebound) to 4+ (deep, prolonged rebound). Pitting edema unilateral = local cause (DVT); bilateral = systemic (HF, liver disease).
- Cranial nerves II–XII: CN II = vision, CN III/IV/VI = eye movement & pupils, CN V = facial sensation, CN VII = facial movement (test with smile, raise brows), CN VIII = hearing, CN IX/X = gag/swallow/uvula (should rise midline), CN XI = shoulder/neck strength, CN XII = tongue (should be midline without fasciculations).
- Urine output normal 0.5–1 mL/kg/hr (~1500 mL/day). Oliguria <400 mL/day, anuria <100 mL/day or none. Hematuria, proteinuria, glycosuria, or cloudy urine (pyuria) are abnormal; assess for UTI, kidney disease, diabetes. Monitor I&O carefully — accurate documentation is essential for fluid balance.
Last minute tips
- When you see 'assess for abnormalities,' think in terms of ABCs first (airway, breathing, circulation), then neurologic changes, then everything else. Prioritize what you report based on severity and urgency. Red flags (stridor, cyanosis, unresponsiveness, absence of pulses) demand immediate action.
- Always compare bilateral structures for symmetry. If findings are asymmetric (e.g., unequal pupils, facial droop, unilateral weakness, one breath sound louder than the other), document precisely which side and consider a focal lesion (stroke, nerve damage, pneumothorax).
- Remember the modified abdominal sequence: Inspect → Auscultate → Percuss → Palpate. This protects the validity of bowel sounds. Listen for a full 5 minutes in all four quadrants before charting bowel sounds as absent. Never palpate a pulsatile mass.
- For auscultation of the heart, use a systematic approach (APE To Man) and identify both S1 (apex, loud) and S2 (base, loud). Listen for the lub-dub rhythm; if you hear an S3 or murmur, note the timing and character. In an exam scenario, any new murmur or irregular rhythm warrants further workup.
- Assess mental status and level of consciousness early. Use the Glasgow Coma Scale if LOC is altered. Orientation to person, place, time, and recent events; memory (immediate, short-term, long-term); ability to follow commands; and appropriate affect are key. Any acute change in cognition = possible delirium, stroke, or metabolic crisis.
Comparison tables
Normal vs. Abnormal Breath Sounds
| Sound Type | Location | Quality | Normal? | Associated Findings |
|---|---|---|---|---|
| Vesicular | Lung periphery | Soft, low-pitched, whooshing | Yes | Normal; indicates air in small airways |
| Bronchovesicular | Main bronchi area (sternal border, scapulae) | Medium pitch/intensity | Yes | Normal; intermediate between vesicular and bronchial |
| Bronchial | Trachea (above sternal notch) | Loud, high-pitched, hollow, tubular | Yes (if over trachea); No (if over lung periphery) | If over periphery = consolidation (pneumonia, pulmonary edema) |
| Crackles | Lung bases or diffuse | Discontinuous, popping/crackling | No | Pneumonia, heart failure, interstitial lung disease, fibrosis |
| Wheezes | Diffuse or focal | Continuous, high-pitched, musical | No | Asthma, COPD, anaphylaxis, airway narrowing |
| Rhonchi | Large airways | Continuous, low-pitched, snoring-like | No | Bronchitis, secretions; may clear with cough |
| Stridor | Upper airway (heard without stethoscope) | High-pitched, inspiratory | No — EMERGENCY | Upper-airway obstruction; croup, foreign body, anaphylaxis |
| Pleural friction rub | Localized to inflamed area | Grating, scratchy | No | Pleurisy, pleural inflammation; may cause pleuritic pain |
Heart Sounds: S1 vs. S2
| Heart Sound | What Closes | Loudest Location | Associated Valve | Timing |
|---|---|---|---|---|
| S1 | Atrioventricular valves (mitral & tricuspid) | Apex (5th ICS midclavicular line) | Mitral (left) > Tricuspid (right) | Marks beginning of systole (ventricular contraction) |
| S2 | Semilunar valves (aortic & pulmonic) | Base (right 2nd ICS for aortic, left 2nd ICS for pulmonic) | Aortic (A2) > Pulmonic (P2) | Marks end of systole / beginning of diastole |
| S3 (abnormal in adults) | Rapid ventricular filling (early diastole) | Apex | Often associated with heart failure, volume overload | Creates 'lub-a-dub' rhythm; normal in children/young adults |
| S4 (abnormal in adults) | Atrial contraction (late diastole, 'atrial kick') | Apex | Stiff, noncompliant ventricle | Creates 'a-lub-dub' rhythm; associated with hypertension, MI |
Pupil Findings: Normal vs. Abnormal
| Pupil Finding | Size | Reaction to Light | Possible Cause/Significance |
|---|---|---|---|
| PERRLA (normal) | 3–5 mm, equal bilaterally | Brisk constriction (reactive) | Normal; fully alert, no neurologic compromise |
| Anisocoria (physiologic) | >1 mm difference, but <2 mm | Both reactive | Benign; seen in ~20% of population |
| Fixed, dilated pupil (>5 mm) | 5+ mm, unilateral | NO reaction to light | EMERGENCY: CN III palsy, increased ICP, brainstem injury, mydriatic drugs |
| Pinpoint pupils (<2 mm) | <2 mm, equal | Minimally reactive or fixed | Opioid intoxication, pontine hemorrhage, organophosphate poisoning |
| Blown pupil (very dilated, fixed) | >5 mm, unilateral, fixed | No response | Herniation, mass effect, CN III compression; neurologic emergency |
Bowel Sound Assessment: Normal vs. Abnormal
| Bowel Sound | Frequency | Character | Associated Condition |
|---|---|---|---|
| Normal | 5–30/min | Gurgling, clicking, irregular | Healthy GI motility; normal if present in all 4 quadrants |
| Hyperactive | >30/min, often loud | High-pitched, frequent | Early mechanical obstruction, gastroenteritis, diarrhea, hunger |
| Hypoactive | <5/min, infrequent | Faint, distant | Ileus (post-op, peritonitis, medication), severe constipation |
| Absent | 0/min (listen ≥5 min before charting) | No sound | Paralytic ileus, severe peritonitis, post-op state (listen full 5 min) |
| Bruits (vascular sounds) | Continuous (usually systolic) | Whooshing, turbulent | Vascular narrowing; abnormal if heard over aorta, renal, iliac arteries |
Edema Grading Scale
| Grade | Depth of Indentation | Rebound Time | Description |
|---|---|---|---|
| 1+ | ~2 mm | Rapid (<2 sec) | Slight, barely perceptible; common in dependent areas |
| 2+ | ~4 mm | Few seconds | Moderate; impression visible but not deep |
| 3+ | ~6 mm | Slow (5–10 sec) | Deep; noticeable indentation |
| 4+ | ~8 mm or deeper | Prolonged (>10 sec) or fails to rebound | Severe; deep pitting, skin stretched and shiny |
