Maternal-Newborn Nursing Essentials
A comprehensive review of maternal-newborn nursing covering the stages of labor and delivery, antepartum complications, postpartum assessment, and newborn care. This guide focuses on the high-yield content most frequently tested on the NCLEX, including fetal monitoring interpretation, postpartum hemorrhage, preeclampsia management, and newborn transition assessment.
Learning Objectives
- ✓Describe the four stages of labor and the expected nursing assessments and interventions for each stage
- ✓Interpret fetal heart rate patterns and identify Category III tracings requiring immediate intervention
- ✓Perform systematic postpartum and newborn assessments and recognize complications requiring escalation
1. Stages of Labor and Intrapartum Nursing Care
Labor is divided into four stages. The first stage begins with the onset of regular contractions and ends with complete cervical dilation (10 cm). It has three phases: latent (0-6 cm, contractions mild and irregular), active (6-8 cm, contractions stronger and more regular), and transition (8-10 cm, contractions intense, close together). During transition, the client may feel nauseated, irritable, and overwhelmed. Nursing care focuses on pain management, position changes, hydration, and emotional support. The second stage begins at complete dilation and ends with the delivery of the baby. This is the pushing stage. Monitor fetal heart rate after every contraction or every 5-15 minutes. Support the client's preferred pushing position and coach effective pushing techniques. The third stage begins after delivery of the baby and ends with delivery of the placenta, typically within 5-30 minutes. Administer oxytocin (Pitocin) as ordered after placental delivery to promote uterine contraction and prevent hemorrhage. The fourth stage is the first 1-2 hours after delivery, during which the nurse closely monitors for postpartum hemorrhage. Assess vital signs every 15 minutes, fundal height and firmness, lochia amount and character, and bladder distension. The fundus should be firm and located at the umbilicus or slightly below. A boggy (soft) fundus indicates uterine atony and requires fundal massage. Lochia should be rubra (red) and moderate in amount.
Key Points
- •First stage: latent (0-6 cm), active (6-8 cm), transition (8-10 cm, most intense phase)
- •Second stage: complete dilation to delivery; monitor FHR after every contraction
- •Third stage: delivery of placenta (5-30 min); administer oxytocin to promote uterine contraction
- •Fourth stage: first 1-2 hours post-delivery; assess fundus, lochia, vitals every 15 minutes
2. High-Risk Antepartum and Postpartum Complications
Preeclampsia is one of the most heavily tested maternal complications on the NCLEX. It is characterized by hypertension (BP 140/90 or greater after 20 weeks gestation) and proteinuria. Severe features include BP 160/110 or greater, elevated liver enzymes, low platelets (HELLP syndrome), and visual disturbances. Treatment includes magnesium sulfate for seizure prophylaxis (therapeutic level 4-7 mEq/L), antihypertensives (labetalol, hydralazine), and delivery when appropriate. Magnesium sulfate toxicity is a critical nursing concern. Monitor deep tendon reflexes (loss of DTRs occurs at approximately 7-10 mEq/L), respiratory rate (hold if below 12 breaths/min), urine output (maintain at least 30 mL/hr), and level of consciousness. The antidote is calcium gluconate, which should be kept at the bedside during magnesium infusion. Postpartum hemorrhage (PPH) is defined as blood loss exceeding 500 mL after vaginal delivery or 1000 mL after cesarean delivery. The most common cause is uterine atony (the uterus fails to contract). Risk factors include overdistended uterus (macrosomia, polyhydramnios, multiple gestation), prolonged labor, magnesium sulfate use, and grand multiparity. Management of uterine atony includes fundal massage, oxytocin administration, and if unresponsive, methylergonovine or carboprost.
Key Points
- •Preeclampsia: BP 140/90+ after 20 weeks with proteinuria; severe features include BP 160/110+ and HELLP
- •Magnesium sulfate: therapeutic 4-7 mEq/L, monitor DTRs, respirations (hold if below 12), urine output (30 mL/hr minimum)
- •Calcium gluconate is the antidote for magnesium toxicity and must be at the bedside during infusion
- •PPH: most common cause is uterine atony; treat with fundal massage and uterotonic medications
3. Newborn Assessment and Transition
The Apgar score is assessed at 1 and 5 minutes after birth, evaluating Appearance (color), Pulse, Grimace (reflex irritability), Activity (muscle tone), and Respirations. Each component is scored 0-2 for a total of 0-10. A score of 7-10 is normal, 4-6 requires some intervention, and 0-3 requires immediate resuscitation. The 1-minute score reflects immediate adaptation, while the 5-minute score better predicts long-term outcomes. Newborn vital signs differ from adult norms: heart rate 120-160 bpm, respiratory rate 30-60 breaths/min, temperature 97.7-99.5 F (36.5-37.5 C). Acrocyanosis (bluish hands and feet) is normal in the first 24-48 hours, but central cyanosis (trunk, mucous membranes) is never normal and requires immediate evaluation. The newborn should pass meconium stool within 24 hours and urinate within the first 24 hours. Routine newborn care includes erythromycin eye ointment (prophylaxis against ophthalmia neonatorum from gonorrhea and chlamydia), vitamin K injection (phytonadione, to prevent hemorrhagic disease of the newborn since neonates lack intestinal flora to synthesize vitamin K), and hepatitis B vaccine within 12 hours of birth. Glucose screening is performed on newborns at risk for hypoglycemia, including infants of diabetic mothers, large-for-gestational-age, and small-for-gestational-age infants.
Key Points
- •Apgar: Appearance, Pulse, Grimace, Activity, Respirations; scored at 1 and 5 minutes, 7-10 is normal
- •Newborn vitals: HR 120-160, RR 30-60, Temp 97.7-99.5 F; central cyanosis is always abnormal
- •Routine care: erythromycin eye ointment, vitamin K IM injection, hepatitis B vaccine within 12 hours
- •Screen at-risk newborns for hypoglycemia: infants of diabetic mothers, LGA, and SGA infants
High-Yield Facts
- ★Late decelerations indicate uteroplacental insufficiency and require immediate intervention: reposition client, stop oxytocin, administer oxygen, notify provider
- ★Variable decelerations are caused by umbilical cord compression and are the most common type of deceleration
- ★A positive Coombs test in the newborn indicates maternal antibodies are attacking fetal red blood cells, increasing jaundice risk
- ★Rh-negative mothers receive RhoGAM at 28 weeks and within 72 hours of delivering an Rh-positive infant

FAQs
Common questions about this topic
Maternal-newborn content falls primarily under the Health Promotion and Maintenance category (6-12% of NCLEX-RN) but also appears in Physiological Integrity questions. You should be prepared for multiple questions on antepartum complications, labor and delivery, postpartum assessment, and newborn care throughout the exam.
Yes. Understanding the stages of labor (1-4), the phases of the first stage (latent, active, transition), expected cervical dilation ranges, and the nursing care priorities for each phase is essential. These concepts are frequently tested and form the foundation for answering questions about intrapartum complications and interventions.
