Midwife Licensure Exam Normal Pregnancy, Labor & Postpartum — Normal Labor & DeliverySummary

Labor outcome depends on the interaction of five interdependent components. The **Passenger** refers to the fetus's characteristics: size (estimated by ultrasound or palpation), **lie** (longitudinal is normal; transverse is abnormal), **presentation** (cephalic/vertex—head first—is ideal; buttocks, shoulder presentations are abnormal), **position** (e.g., LOA—left occiput anterior—the most common and favorable orientation), and **attitude** (full flexion presents the smallest head diameter, optimizing passage). The **Passage** comprises the bony pelvis (gynecoid shape is most favorable; android, platypelloid, and anthropoid types may obstruct) and soft tissues (vagina, perineum). The **Powers** are uterine contractions (primary—involuntary) and maternal pushing/bearing down (secondary—voluntary, during stage 2). **Position** (maternal) affects gravity, pelvic diameter, and placental perfusion; upright and left-lateral positions are optimal. **Psyche** encompasses the woman's emotional state; anxiety and fear increase pain perception, tension, and catecholamine release, which can inhibit labor and reduce placental perfusion. Dystocia (abnormal labor) results when any P is abnormal. In Philippine settings, nurses assess these factors using Leopold's maneuvers, sterile vaginal exams, and clinical judgment to guide safe-motherhood decisions.

Distinguishing true labor from Braxton Hicks (false labor) contractions is the first nursing assessment. **False labor (Braxton Hicks)** presents with irregular contractions that do not intensify, ease with walking, cause mostly abdominal/suprapubic discomfort, leave the cervix unchanged, and are not accompanied by bloody show. **True labor** is characterized by **regular, increasingly frequent contractions** (establishing a pattern), intensification with walking, discomfort radiating from the fundus to the back and front, **progressive cervical dilation and effacement**, and presence of bloody show (blood-tinged mucus from the cervical plug). **Cervical change is the definitive sign of true labor**—this is the criterion nurses use when women present to health facilities uncertain whether they are in labor. Other premonitory signs include **lightening** (fetal descent into the pelvis, usually 2–4 weeks before term in primigravidas, causing relief of upper abdominal pressure but increased urinary frequency and pelvic pressure), **Braxton Hicks contractions** (irregular, painless or mildly uncomfortable), cervical ripening (softening, effacement, and anterior positioning), a burst of energy/nesting behavior, slight weight loss (0.5–1.5 kg, possibly due to loss of amniotic fluid or hormonal shift), and passage of the bloody show.

Labor is divided into four distinct stages, each with specific clinical characteristics and nursing interventions. **Stage 1: Onset of true labor to full (10 cm) cervical dilation** is the longest stage (average 8–12 h in primigravidas, 4–8 h in multipara). It has three phases: (1) **Latent phase** (0–3/4 cm dilation, some references to 5–6 cm): contractions are mild, occurring every 5–10 minutes; the woman is sociable, comfortable, and able to walk and converse. Nursing care focuses on ambulation, hydration, light nutrition, and encouragement. (2) **Active phase** (~4–7 cm): contractions increase in intensity and frequency (every 3–5 minutes, lasting 40–60 seconds); the woman becomes serious, inward-focused, and may request analgesia (this is the typical time epidural placement is considered). Continuous fetal monitoring begins, and support intensifies. (3) **Transition phase** (8–10 cm): the most intense and uncomfortable phase; contractions occur every 2–3 minutes, lasting 60–90 seconds; the woman may be irritable, nauseated, trembling, sweating, and experiencing rectal pressure and an urge to push. **Critically, she must not push until the cervix is fully dilated (10 cm), because premature pushing can cause cervical edema and lacerations.** Effacement (cervical thinning, 0–100%) occurs simultaneously with dilation; in primigravidas, 80–90% effacement often precedes dilation. **Stage 2: Full cervical dilation to delivery of the baby** is shorter (average 30 min–2 h in primigravidas, <30 min in multipara). It begins when the cervix is fully dilated and the woman feels an involuntary urge to push. The **cardinal movements (mechanisms of labor)** occur: **Engagement** (fetal head enters the pelvic inlet), **Descent** (progressive downward movement), **Flexion** (chin flexes toward chest), **Internal rotation** (head rotates to align with pelvic outlet), **Extension** (head extends as it passes under the pubic symphysis), **External rotation** (restitution—head rotates externally to align with the fetal shoulders and body), and **Expulsion** (delivery of the body). **Crowning** occurs when the fetal head is visible at the introitus and no longer retracts between contractions. During stage 2, nurses assist effective pushing, support controlled delivery to minimize perineal trauma, check for nuchal cord, and provide encouragement. **Stage 3: Delivery of the baby to delivery of the placenta** typically lasts 5–30 minutes. Signs of placental separation include a **gush of blood**, **lengthening of the umbilical cord** (becomes more slack as the placenta descends), the **uterus becoming globular and firm** (contracting around the smaller placenta), and the **fundus rising** as the placenta moves into the lower uterine segment and vagina. The nurse supports **controlled cord traction** only after uterine contraction is confirmed (countertraction on the uterus prevents inversion), avoiding aggressive cord pulling. The placenta is inspected for completeness (retained fragments cause postpartum hemorrhage). **Schultze delivery** (shiny fetal surface appears first, 80% of placentas) or **Duncan delivery** (dull, rough maternal surface appears first, called "dirty Duncan") describes the presentation. **Stage 4: First 1–2 hours after placental delivery** is the critical recovery period and the **highest risk for postpartum hemorrhage (PPH)**. The uterus must remain firmly contracted; **a boggy (soft) uterus is the first sign of atony (failure to contract), the leading cause of PPH**. The nurse assesses the fundus (should be firm, at the midline, at or below the umbilicus), lochia character and volume, vital signs, bladder fullness, and perineal wounds every 15 minutes in the first hour. Oxytocic agents are given to maintain contraction.

The cardinal movements describe the sequential changes in fetal position as the head navigates the maternal pelvis during labor and delivery. Mastering this concept is crucial because incorrect understanding of fetal mechanics can lead to misinterpreting clinical signs and misjudging delivery readiness. The seven movements, in order, are: **Engagement** (the widest diameter of the presenting part enters the pelvic inlet; the fetal head descends from station -5 to -3 or higher, depending on pelvic architecture), **Descent** (progressive downward movement of the fetus through the pelvic canal, aided by uterine contractions and maternal pushing), **Flexion** (the fetal head flexes more completely, with the chin approaching the chest, presenting the smallest diameter—the suboccipitobregmatic diameter), **Internal rotation** (the head rotates approximately 45° or more so that the occiput (back of the head) comes under the pubic symphysis; in most vertex presentations, the head rotates from LOA or ROA to OA—occiput anterior—the most favorable position for passage), **Extension** (once the occiput is under the symphysis, the head extends as it pivots over the symphysis, bringing the forehead, nose, mouth, then chin over the perineum), **External rotation** or **restitution** (after the head is delivered and extension is complete, the head rotates externally about 45° to realign with the fetal shoulders and body; the occiput rotates back slightly), and **Expulsion** (the shoulders and rest of the body are delivered, first the anterior shoulder under the symphysis, then the posterior shoulder over the perineum). A common mnemonic is **"Every Decent Family In Elk Ridge Enjoys" (Engagement, Descent, Flexion, Internal rotation, Extension, Restitution, Expulsion)**. **Station** (the relationship of the presenting part to the ischial spines, measured in cm from -5 [at the inlet] through 0 [at the ischial spines] to +5 [at the introitus]) helps clinicians track descent. Understanding these mechanics helps nurses anticipate when the woman will begin pushing, when the head will crown, and when delivery is imminent.

Continuous FHR monitoring during labor is a cornerstone of fetal surveillance and allows nurses to assess fetal oxygenation and well-being. **Normal baseline FHR is 110–160 beats per minute (bpm)**; below 110 is bradycardia, above 160 is tachycardia. **Baseline variability**—the oscillation of the FHR around the baseline—is a key indicator of fetal well-being. **Moderate variability (6–25 bpm fluctuations)** is reassuring and indicates intact fetal neurological function and adequate oxygenation. **Minimal or absent variability** is concerning and suggests hypoxia or medication effects (e.g., opioids). **Accelerations** are transient increases in FHR (typically ≥15 bpm above baseline, lasting 15–20 seconds) that occur with fetal movement or contractions. **Accelerations are reassuring**; they indicate fetal well-oxygenation and responsiveness. **Decelerations** are transient decreases in FHR and are classified by their timing and shape: **Early decelerations** mirror the contraction (begin as the contraction starts, reach nadir at the peak, and return to baseline as the contraction ends); they are caused by **fetal head compression** as the head descends and the uterus contracts around it. **Early decelerations are benign and require no intervention beyond observation.** **Variable decelerations** are abrupt (onset <30 seconds), have a variable relationship to contractions, and appear V-shaped or W-shaped; they are caused by **umbilical cord compression** (the cord is compressed between the fetus and uterine wall). **Variable decelerations are common and usually benign**, but their presence warrants assessment of cord around the neck (nuchal cord), polyhydramnios, or oligohydramnios. **Late decelerations** begin after the peak of the contraction and return to baseline after the contraction ends; they are caused by **uteroplacental insufficiency** (reduced placental perfusion during uterine contraction, leading to transient fetal hypoxemia). **Late decelerations are ominous and demand immediate nursing intervention.** **Prolonged decelerations** (lasting >2 minutes) suggest severe hypoxia or cord compression and require emergency response. Other concerning patterns include **fetal tachycardia** (>160 bpm, possibly from fever, hyperthyroidism, or fetal hypoxia), **bradycardia** (<110 bpm, from vagal stimulation, heart block, or severe hypoxia), and **loss of variability** (flat baseline, concerning for hypoxia or medication). In the Philippine context, many rural health units use intermittent auscultation (listening with a stethoscope or Pinard fetoscope every 5–15 minutes) rather than continuous electronic monitoring; proper technique is essential for accurate baseline and detection of decelerations.

Uterine contractions are the primary power of labor. Nurses assess contractions using four parameters: **Frequency** (the interval from the start of one contraction to the start of the next, measured in minutes; normal labor progresses from every 5–10 minutes in the latent phase to every 2–3 minutes in transition), **Duration** (the time from the beginning of a contraction to its end, measured in seconds; normal is 30–60 seconds in early labor, progressing to 60–90 seconds in transition), **Intensity** (the strength of the contraction, assessed by palpation as mild, moderate, or strong, or measured objectively by an intrauterine pressure catheter [IUPC] in mm Hg; mild = <30 mm Hg, moderate = 30–50 mm Hg, strong = >50 mm Hg), and **Resting tone** (the baseline uterine pressure between contractions; normal is 5–15 mm Hg with IUPC, or a relaxed fundus on palpation). Contractions are documented as a description, e.g., "Contractions every 3 minutes, lasting 50 seconds, of moderate intensity, with good relaxation between." **Uterine hyperstimulation** or **tetany** occurs when contractions become more frequent than every 2 minutes, last longer than 90 seconds, or the resting tone never fully relaxes (uterus remains tense). This is **dangerous** because it reduces placental blood flow (contractions compress placental vessels; if the uterus doesn't relax, perfusion never recovers), leading to **fetal hypoxia**, and increases the risk of **uterine rupture** (especially in a uterus with a prior scar). Hyperstimulation may result from excessive oxytocin or rarely from spontaneous excessive uterine activity. Nursing response to hyperstimulation is immediate: **stop oxytocin** (or any labor-augmenting agent), **reposition the woman to her left side or knee-chest**, **give supplemental oxygen** (8–10 L/min by mask), **increase IV fluid rate** (bolus to correct any hypotension and improve placental perfusion), and **notify the physician**. Contractions are monitored continuously or intermittently depending on risk level; low-risk women in active labor may have auscultated FHR every 5–15 minutes with palpated contractions, while high-risk women or those on oxytocin receive continuous electronic monitoring.

Oxytocin (Pitocin) is a synthetic form of the posterior pituitary hormone that stimulates uterine contractions. It is used for **labor induction** (starting labor in a non-laboring woman) and **labor augmentation** (strengthening contractions in a woman with inadequate labor). **Critical point: Oxytocin for labor induction/augmentation is always given as a dilute IV infusion via an infusion pump, starting at a low dose (e.g., 0.5–1 mIU/min) and titrated incrementally (increasing by 1–2 mIU/min every 15–30 minutes) until effective contractions occur (typically every 2–3 minutes of moderate-to-strong intensity).** **Oxytocin is NEVER given as an IV push for labor induction**—this would cause dangerously strong contractions and tetany. After delivery, oxytocin is given to contract the uterus and control postpartum bleeding; this may be given as **10 units IM** or added to IV fluid (e.g., 10 units in 500 mL normal saline) infused at a rate to maintain uterine tone. **Nursing responsibilities for oxytocin infusion include**: (1) Ensure IV access is large-bore (18 G or larger); use a separate IV line if possible to prevent solution backing up if IV is stopped. (2) Prime the IV tubing with the oxytocin solution before connecting to the patient. (3) Use an infusion pump (never gravity or manual flow). (4) Start at the ordered dose and increase incrementally; never increase more frequently than every 15–20 minutes or faster than the institution protocol allows. (5) Continuously monitor **contractions** (frequency, duration, intensity, resting tone) and **FHR** for signs of fetal distress or uterine hyperstimulation. (6) **If hyperstimulation occurs (contractions <2 min apart, lasting >90 sec, or resting tone elevated), IMMEDIATELY stop the infusion**, reposition the mother, give oxygen, increase IV fluids, and notify the physician. (7) Document baseline FHR, maternal vital signs, and contraction patterns before starting and at regular intervals. **Adverse effects of oxytocin include**: uterine tetany/hyperstimulation (→ fetal hypoxia, placental abruption, uterine rupture), maternal water intoxication (from ADH effect of high-dose continuous oxytocin; rare with appropriate dilution), maternal hypertension, nausea/vomiting, and uterine rupture in susceptible women (e.g., uterus with prior scar). In the Philippine healthcare context (RA 9173), nurses may initiate oxytocin infusions under physician orders in tertiary facilities and some secondary facilities, but must have protocols for monitoring and emergency response. Augmentation with oxytocin is a key intervention for prolonged/dysfunctional labor, but nurses must distinguish between poor contractions (amenable to augmentation) and arrest of descent due to cephalopelvic disproportion (CPD), which requires cesarean delivery, not oxytocin.

Pain management during labor is a key component of compassionate, evidence-based care. **Pharmacologic options** include: (1) **Epidural analgesia** (local anesthetic infused into the epidural space, typically bupivacaine ± fentanyl), which provides excellent pain relief and allows the woman to remain awake and participate in pushing. An anesthesiologist or trained nurse anesthetist places the catheter, usually during active labor (4–5 cm dilation). **Advantages**: effective pain relief, allows rest, enables informed decision-making. **Main risk**: **maternal hypotension** (due to vasodilation from the local anesthetic), which reduces placental perfusion and can cause fetal bradycardia. **Nursing prevention and management**: (a) Administer an IV fluid bolus (500–1000 mL) of non-dextrose-containing solution 15–30 minutes before epidural placement to expand intravascular volume. (b) Position the woman on her **left lateral side** after epidural placement (improves placental perfusion). (c) Monitor maternal blood pressure and FHR closely. (d) If hypotension occurs (SBP <20% of baseline or <90 mmHg systolic), position left lateral, increase IV fluid rate, give supplemental oxygen, and notify the anesthesiologist. (e) **Ephedrine** (a vasopressor, 5–10 mg IV/IM) may be ordered. Other epidural risks include inadequate pain relief (requiring reposition or replacement), urinary retention (so catheterization may be needed), and rare complications like dural puncture (spinal headache). (2) **Opioids** (e.g., meperidine 12.5–25 mg IV, nalbuphine 10–20 mg IV/IM): these provide systemic analgesia; the woman feels relaxed and may sleep between contractions. **Advantages**: available, less invasive than epidural. **Disadvantages**: incomplete pain relief, nausea, maternal drowsiness, and **risk of neonatal respiratory depression if given close to delivery** (within 1–4 hours of birth, depending on the drug). **Nursing precaution**: Before administering an opioid, confirm that delivery is not imminent. Always have **naloxone** (Narcan) readily available in the labor/delivery unit and newborn resuscitation area; if the newborn is lethargic or has depressed respirations, naloxone 0.1 mg/kg IV/IM can reverse respiratory depression. (3) **Local/Pudendal blocks**: local anesthetic (lidocaine) infiltrated into the perineum for pain relief during the second stage and episiotomy repair; does not provide pain relief for contractions. (4) **Spinal blocks**: one-time injection of local anesthetic into the subarachnoid space; onset is rapid (1–2 minutes); used primarily for cesarean delivery but may be used for instrumental delivery. **Non-pharmacologic options** include: (1) **Continuous labor support** (from a doula, partner, family member, or nurse): non-judgmental presence, encouragement, and hands-on support reduce pain perception, anxiety, and need for pharmacologic analgesia; in Philippine settings, families are traditionally involved in labor support. (2) **Breathing and relaxation techniques** (e.g., Lamaze method, deep diaphragmatic breathing, patterned breathing with contractions): help the woman focus and reduce tension. (3) **Position changes and ambulation**: upright positions (sitting, standing, squatting) and movement enhance gravity-assisted descent and comfort; encourage frequent position changes. (4) **Hydrotherapy (shower or tub)** (if membranes are intact and risk is low): warm water promotes relaxation and pain relief. (5) **Massage and counter-pressure**: partner or nurse applies firm pressure to the lower back during contractions, especially helpful for back labor (OP position). (6) **Heat/cold application**: warm compresses to the perineum, back, or abdomen; cold packs to specific areas. (7) **Hypnobirthing/self-hypnosis**: some women benefit from focused relaxation and positive visualization. (8) **Acupressure/acupuncture** (if available): pressure on specific points may relieve pain. **Philippine context**: Many rural and community settings lack pharmacologic options; non-pharmacologic comfort measures and family support are the mainstay of pain management. Nurses should be skilled in these techniques and provide encouragement and presence. Informed choice and shared decision-making are fundamental to RA 9173 professional practice.

The Department of Health's **Unang Yakap ("First Embrace")** protocol is the Philippine evidence-based standard for immediate newborn care and operationalizes the World Health Organization's Essential Intrapartum and Newborn Care (EINC) guidelines. This protocol improves newborn survival and reduces complications by prioritizing four time-bound, simple interventions that every birth attendant in the Philippines must know and implement. **The four core EINC steps are**: (1) **Immediate and thorough drying of the newborn** (within the first 5–10 seconds after delivery): the wet newborn is dried with clean, warm cloths or towels; drying provides stimulation (often triggering the newborn's first cry and breath), prevents **hypothermia** (a leading cause of neonatal morbidity and mortality in resource-limited settings), and enables assessment of skin color and tone. Drying must be thorough, including the head and ears. (2) **Early skin-to-skin contact (SSC)** between the mother and newborn (immediately after drying): the dried newborn is placed prone (chest-to-chest) on the mother's abdomen or chest, covered with a blanket if needed; the mother and infant remain in direct contact. **Benefits of early SSC**: (a) Maintains newborn body temperature through maternal warmth (kangaroo care). (b) Stabilizes newborn heart rate, respiratory rate, and blood glucose. (c) Initiates bonding and promotes breastfeeding readiness. (d) Reduces neonatal stress and pain perception. (e) Decreases infection risk in some studies. SSC should be uninterrupted for at least 1–2 hours unless there is a medical complication. (3) **Properly timed cord clamping and cutting**: the umbilical cord is clamped and cut **after cord pulsations cease** (typically 1–3 minutes after birth in term infants, longer in preterm infants or if the cord is short). **Benefits of delayed cord clamping**: (a) Allows placental blood to transfuse into the newborn, increasing blood volume and hemoglobin levels. (b) Improves neonatal iron stores, reducing iron-deficiency anemia risk in infancy. (c) May improve neurodevelopmental outcomes (though evidence is ongoing). (d) Reduces need for blood transfusion in preterm infants. **When to clamp earlier**: if the cord is very short, there is heavy bleeding, or the newborn is severely compromised (needs immediate resuscitation). (4) **Non-separation of mother and baby and early breastfeeding initiation**: the mother and newborn are not separated; rooming-in begins immediately. The first breastfeed is encouraged within the first hour (the "first golden hour"). The newborn, if alert and vigorous, often exhibits breastfeeding cues (hand-to-mouth movements, rooting) and may crawl and self-latch onto the mother's breast. **Benefits**: (a) Establishes breastfeeding; colostrum provides immune factors and nutrition. (b) Maintains warmth and bonding. (c) Delays separation, reducing maternal-infant stress. (d) Reduces hypothermia and hypoglycemia in the newborn. (e) Initiates exclusive breastfeeding, improving infant health outcomes. (f) Promotes maternal uterine contraction and hemostasis (oxytocin released during breastfeeding). **Additional EINC principles** (beyond the four core steps) include: avoiding unnecessary suctioning (suction only if the airway is obstructed by meconium or secretions, not routine), avoiding early bathing (bathe only after the infant is stable and hypothermia risk is minimized; vernix caseosa provides skin protection), keeping the newborn warm (place on mother's chest, cover appropriately), and immediate assessment for danger signs (difficulty breathing, severe congenital anomalies, lack of response). In Philippine health facilities, nurses and midwives are responsible for implementing Unang Yakap at every delivery, from tertiary centers to remote rural health units. This is enshrined in national maternal-child health policy and is a key competency for NLE and clinical practice.

**Rupture of membranes (ROM)** occurs when the amniotic sac tears, allowing amniotic fluid to leak or gush into the vagina. ROM may occur spontaneously (most common, called SROM) or artificially (amniotomy—intentional rupture by the healthcare provider, called AROM). **Assessment of ROM** includes: (1) Confirming rupture: women report a gush or steady trickle of fluid; the nurse performs a sterile vaginal exam and uses **nitrazine paper** (amniotic fluid is alkaline, turning the paper blue-green) and **fern test** (amniotic fluid crystallizes in a fern-like pattern when dried on a slide). (2) **Noting time of rupture** (critical for detection of infection; in the Philippines, prolonged rupture of membranes (PROM) is >12 hours, increasing infection risk). (3) **Observing color, amount, and odor**: **Clear fluid** is normal; **green/dark-stained (meconium-stained) fluid** indicates fetal distress or passage of meconium, requiring closer FHR monitoring; **foul-smelling or yellow fluid** suggests **intra-amniotic infection (chorioamnionitis)**, necessitating culture and likely IV antibiotics and expedited delivery. (4) **Immediately checking FHR** after ROM (critical safety step): the **risk of umbilical cord prolapse** is highest immediately after ROM, especially if the presenting part is unengaged (high, mobile) or if the presentation is not cephalic. **Cord prolapse** occurs when the umbilical cord slips into the vagina ahead of the presenting part; it may be **overt** (cord visibly protruding from the introitus) or **occult** (cord compressed between the fetus and pelvic wall, not visible). **Signs of cord prolapse**: sudden **variable deceleration** or **prolonged deceleration** of the FHR, **bradycardia**, or **loss of FHR** shortly after ROM. **Nursing emergency response to suspected cord prolapse**: (a) **Immediately alert the physician and call for emergency delivery.** (b) **Relieve pressure on the cord**: position the mother in **knee-chest** (on hands and knees, pelvis elevated) or **steep Trendelenburg** (head down, pelvis elevated, to use gravity to move the fetus off the cord). (c) **If cord is visible, keep it moist** (do not attempt to push it back in; wrap it gently in a sterile, saline-soaked compress). (d) **Insert a gloved hand into the vagina and gently lift the presenting part off the cord**, maintaining upward pressure until delivery occurs (this may be done while the mother is repositioned or in an emergency setting). (e) **Give supplemental oxygen** by mask. (f) **Avoid further trauma**: do not palpate the cord unnecessarily; do not allow the cord to dry out or become cold. (g) **Expedite delivery**: in most cases, emergency cesarean delivery is required; rarely, if delivery is imminent, vaginal delivery under close supervision may proceed. In Philippine settings, recognizing cord prolapse and initiating immediate action is a nurse's critical responsibility because transfer to a surgical center may require transport time. **Prevention of cord prolapse** includes: avoiding artificial rupture of membranes (AROM) when the presenting part is unengaged, limiting ambulation immediately after spontaneous ROM if engagement is questionable, and immediate FHR assessment.

**Systematic maternal assessment during labor** guides decisions about progress, complications, and appropriate interventions. **Vital signs** are recorded at admission, periodically during labor (every 1–2 hours in low-risk labor, more frequently if abnormal or if epidural is placed), and frequently during stage 2 and postpartum. **Normal vital signs in labor**: temperature <37.5°C (elevated temperature suggests infection or dehydration), pulse 60–100 bpm (tachycardia may indicate pain, anxiety, dehydration, or infection), respiratory rate 12–20/min (tachypnea may indicate pain or anxiety), and blood pressure within the woman's baseline (a rise >30 mmHg systolic or 15 mmHg diastolic warrants investigation for preeclampsia, though some rise is normal with contractions). **Pelvic exams** (sterile vaginal exams) are performed at admission, periodically to assess progress (frequency depends on clinical indication; avoid frequent exams once membranes are ruptured, as each exam introduces infection risk), and at delivery. **Information obtained from a pelvic exam includes**: (1) **Cervical status**: dilation (0–10 cm), effacement (0–100%), consistency (firm/medium/soft), and position (posterior/mid/anterior)—useful in assessing labor progress. (2) **Fetal descent and station**: the position of the presenting part relative to the ischial spines, from -5 (at the inlet) to +5 (at the introitus); descent is the most reliable sign of labor progress. (3) **Fetal position**: determined by palpating the fetal skull landmarks (occiput, anterior fontanelle, sagittal suture); LOA and LOP are the most common; OP may be associated with prolonged labor and maternal back pain. (4) **Pelvic adequacy assessment**: limited by the vaginal exam but informed by the ease of progression; obvious contracted pelvis or inability to descend despite good contractions suggests CPD. (5) **Membrane status**: intact, ruptured, or bulging. (6) **Vaginal abnormalities**: scars, masses, strictures. **Leopold's maneuvers** (abdominal palpation) are performed at admission to determine fetal lie, presentation, and position without inserting fingers into the vagina; they guide decisions about vaginal exams and help identify malpresentation. **Four steps**: (1) Face the woman's head; place both hands on the fundus to determine which fetal pole (head or buttocks) is there. (2) Place hands on either side of the uterus to determine which side the fetal back is on (side of greatest resistance to palpation). (3) Grasp the lower uterine segment above the symphysis to identify the presenting part. (4) Turn to face the woman's feet and palpate the pelvic inlet to confirm presentation and descent. **Other assessments**: **urine output** (monitor for dehydration; void frequently to prevent bladder distention, which impedes descent), **perineal inspection** for edema, trauma, or masses, and **maternal coping** (assess pain level, effectiveness of coping strategies, need for additional support or analgesia). **In the Philippine context**, nurses in rural health units may perform these assessments with minimal technology; palpation skills, visual inspection, and clinical judgment are essential. Vaginal exams should be performed with appropriate infection prevention (clean/sterile technique per setting capabilities) and within the nurse's scope of practice as defined by RA 9173 and facility protocols.

**Fetal distress** (now termed **non-reassuring fetal status** in modern obstetrics) is characterized by patterns suggesting fetal hypoxemia or acidosis, particularly **late decelerations**, **significant variable decelerations**, **fetal tachycardia** (>160 bpm) with loss of variability, **prolonged deceleration** (>2 minutes), or **absent variability**. **The intrauterine resuscitation bundle** is a set of evidence-based interventions that nurses implement immediately when fetal distress is suspected, with the goal of improving placental perfusion and fetal oxygenation before an emergency delivery is needed. **The priority steps (a common framework is STOP)** are: (1) **Stop oxytocin** (or any uterotonic): oxytocin-induced contractions reduce placental blood flow; stopping the infusion allows the uterus to relax and restores perfusion. (2) **Turn the mother to her left lateral side** (or reposition if already on the left; knee-chest is an alternative): left-lateral position optimizes uterine blood flow and relieves aortocaval compression (compression of the aorta and vena cava by the gravid uterus when supine, reducing perfusion). (3) **Oxygen** by face mask at 8–10 L/min: increases maternal arterial oxygen saturation, improving the oxygen gradient across the placenta. (4) **Notify the physician immediately** and prepare for possible emergency cesarean or operative delivery. **Additional measures** include: (5) **Increase IV fluid infusion** (bolus of 500–1000 mL of non-dextrose solution) to increase maternal intravascular volume and correct hypotension if present, improving placental perfusion. (6) **Assess maternal vital signs** and correct hypotension (systolic BP <90 mmHg or >20 mmHg drop from baseline). (7) **Check for and relieve cord compression**: assess for **nuchal cord** (cord around the fetus's neck) during delivery or by vaginal exam, or look for **polyhydramnios** (excess fluid that increases cord mobility and compression risk) or **oligohydramnios** (inadequate fluid, tightening cord around the fetus). (8) **Examine the mother** for signs of **placental abruption** (vaginal bleeding, abdominal pain, rigid uterus) or **uterine rupture** (severe abdominal pain, loss of contractions, fetal heart tones). (9) **Promote spontaneous contractions** if labor has not progressed; sometimes the mother's own contractions resume and are adequate. (10) **Keep the woman NPO** (nothing by mouth) in case emergency surgery is needed. **Timing is critical**: fetal brain damage can occur within 5–10 minutes of severe hypoxia; every minute counts. In Philippine settings, if fetal distress is suspected and cesarean delivery is not available on-site, arrangements for urgent transfer must be made immediately, while intrauterine resuscitation measures are ongoing. **Documentation** of the time distress was noted, interventions performed, times, and FHR responses is essential for medical-legal protection and clinical continuity. Nurses must communicate clearly with the physician and team to ensure coordinated, rapid response.

**Postpartum hemorrhage (PPH)** is defined as blood loss >500 mL after vaginal delivery (or >1000 mL after cesarean delivery) and is the leading cause of maternal death in low-resource settings, including parts of the Philippines. **The fourth stage of labor (the first 1–2 hours after delivery)** is the **highest-risk period for PPH** because the uterus must maintain contraction to compress bleeding vessels in the placental bed. **The leading cause of PPH is uterine atony** (failure of the uterus to contract or maintain contraction). **Early recognition is key; the first sign of atony is a boggy (soft, spongy) uterus.** **Nursing assessment during the fourth stage** includes **frequent evaluation every 15 minutes in the first hour**: (1) **Fundus palpation**: assess location (should be at the umbilicus or below), firmness (should be firm/hard; a boggy fundus indicates atony), and position (should be midline; deviation suggests full bladder or retained clots). (2) **Lochia assessment**: observe flow (should be moderate, not excessive), color (bright red initially, then gradually darkening), and any clots (small clots <walnut size are normal; large clots suggest retained products). (3) **Perineal inspection**: observe for bleeding from lacerations or episiotomy; saturated pads, blood running down the legs, or blood pooling beneath the mother suggests excessive bleeding. (4) **Vital signs**: check blood pressure (hypotension and tachycardia are late signs of hypovolemia; a drop of >20 mmHg or a pulse >100 bpm warrants investigation), temperature, and respiratory rate. (5) **Bladder status**: a full bladder can impede uterine contraction and cause the fundus to feel boggy and deviate; encourage voiding and catheterize if necessary. (6) **Maternal color and mental status**: pale, cool, clammy skin, anxiety, and altered mental status are signs of hypovolemia and shock. **Prevention of PPH** starts during the **third stage** with appropriate management: (a) **Controlled cord traction** after signs of placental separation are confirmed (gush of blood, cord lengthening, fundus rise), with **countertraction** on the uterus to prevent inversion. (b) **Oxytocic administration** per protocol (e.g., **oxytocin 10 units IM** after delivery or added to IV fluids); in settings where IV access is not available, **ergot alkaloids** (ergotamine, methylergonovine) or **misoprostol** (Cytotec) may be used as alternatives, though oxytocin is preferred. (c) **Early cord clamping** (in cases of placental abruption or maternal bleeding concerns, though delayed clamping is standard). (d) **Inspection of the placenta** for completeness; if fragments are retained, manual removal or curettage may be needed. **Fourth-stage PPH management** if atony is detected: (1) **Massage the fundus** firmly with one hand (in a circular motion) while providing **counter-pressure** on the lower uterus with the other hand, until the uterus becomes firm; this stimulates contraction and expels clots. (2) **Empty the bladder** (straight catheterization if unable to void). (3) **Ensure IV access** and begin fluid resuscitation if bleeding is heavy. (4) **Administer oxytocin** if not already given (10 units IM, or infuse in IV fluids). (5) **Notify the physician** if bleeding persists despite massage or if signs of shock develop. (6) **Keep the woman NPO**, type and cross-match blood if not already done. (7) **Monitor vital signs frequently** and reassess the fundus every 5–10 minutes until stable. (8) **Consider other causes** of PPH: **genital tract trauma** (lacerations, episiotomy bleeding), **coagulopathy** (rare but serious), **retained placental fragments**, or **placental bed bleeding** (uterine vessels not adequately compressed). In resource-limited Philippine settings, maternal mortality from PPH is high because blood transfusion and surgical intervention may not be immediately available; therefore, **skilled assessment, prompt fundal massage, oxytocin administration, and early referral are life-saving**. **RA 9173 scope of practice** allows nurses to assess for and manage fundal atony with massage and oxytocin per protocol.

**NANDA International nursing diagnoses** provide a standardized language for identifying patient problems and guiding nursing interventions. In the labor and delivery context, nurses formulate diagnoses based on assessment findings and use **Maslow's hierarchy of needs** to prioritize care. **Common NANDA diagnoses in labor include**: (1) **Acute pain** (related to uterine contractions and cervical dilation): manifested by facial grimacing, verbal reports of pain, muscle tension. **Interventions**: provide non-pharmacologic comfort (breathing, position changes, massage), administer analgesia as ordered, educate about coping strategies, provide continuous support. (2) **Risk for ineffective coping** (related to pain, stress of labor, previous experiences): **Interventions**: provide reassurance, explain labor progress, offer choice in pain management, involve support persons. (3) **Ineffective breathing pattern** (related to pain, anxiety, epidural use): **Interventions**: teach breathing techniques, position for optimal chest expansion, monitor oxygen saturation, give oxygen if SpO2 is low. (4) **Deficient knowledge** (related to labor process, expectations, coping): **Interventions**: provide education about labor stages, positions, coping, and what to expect. (5) **Risk for fetal injury** (related to complications such as cord prolapse, hypoxia, or instrumentation): **Interventions**: monitor FHR continuously, assess for complications, perform intrauterine resuscitation if needed, prepare for emergency delivery. (6) **Anxiety** (related to labor, fear of pain, fear of complications): **Interventions**: provide reassurance, explain what is happening, involve support persons, offer coping strategies, consider anxiolytics if appropriate. (7) **Urinary retention** (related to epidural, prolonged labor, full bladder): **Interventions**: encourage voiding, catheterize if necessary to facilitate descent. (8) **Risk for hemorrhage** (related to uterine atony, trauma, or placental abruption, especially during third and fourth stages): **Interventions**: administer oxytocin, massage fundus, monitor lochia, assess vital signs frequently, ensure IV access. **Maslow's hierarchy applied to labor care**: **Physiologic needs** (safety needs, in Maslow's ordering) are the **highest priority** in labor: (a) **Adequate oxygen** (for both mother and fetus): assess maternal and fetal oxygen status; give supplemental oxygen if needed; monitor FHR for signs of hypoxia. (b) **Hemodynamic stability** (blood pressure, perfusion): monitor vital signs; prevent and manage hypertension, hypotension, and bleeding. (c) **Fluid and nutritional status** (though oral intake may be restricted in labor): ensure hydration with IV fluids; provide light nutrition or fluids if not contraindicated. (d) **Pain control and comfort**: provide analgesia and comfort measures. (e) **Bladder and bowel function**: encourage voiding; expect bowel movements during labor. **Safety needs** (protection from injury): (a) **Fetal safety**: monitor for distress, prepare for emergency delivery, prevent cord prolapse, use assisted delivery if needed. (b) **Maternal safety**: monitor for hemorrhage, infection, trauma; maintain asepsis; prevent falls. (c) **Psychological safety**: reduce fear and anxiety through information, support, and control. **Love and belonging needs**: (a) Involve the family/partner in labor support. (b) Respect cultural practices. (c) Provide continuity of care and personal attention. **Esteem needs** (self-efficacy, autonomy): (a) Involve the woman in decision-making. (b) Affirm her coping and progress. (c) Respect her preferences for pain management and positioning. **Self-actualization needs**: (a) Support the woman's birth goals (e.g., vaginal delivery, presence of specific support persons, skin-to-skin contact). (b) Facilitate Unang Yakap (EINC) to promote early bonding and breastfeeding. **In the Philippine nursing context**, aligning care with RA 9173 scope of practice and NCM levels, nurses use NANDA diagnoses and Maslow's framework to provide holistic, culturally-sensitive, evidence-based care. For example, a woman in active labor with acute pain and anxiety may have nursing diagnoses of **Acute pain** and **Anxiety**; prioritization according to Maslow would address **pain first** (physiologic need), followed by **reassurance and support** (safety/love and belonging). If fetal distress develops, **Risk for fetal injury** becomes the top priority, and all actions shift to intrauterine resuscitation and emergency response.
