Maternal and Newborn Nursing
Core concepts
This domain spans antepartum, intrapartum, postpartum, and newborn care. Master the estimated date of delivery (Naegele's rule), prenatal risk factors, the stages of labor and their expected findings, fetal monitoring (baseline rate, variability, accelerations, decelerations), postpartum hemorrhage risk and assessment (fundal height, lochia, uterine tone), breastfeeding basics, and newborn transition (Apgar, thermoregulation, jaundice, glucose).
Traps candidates fall for
- Misreading fetal heart tracings: early decelerations mirror contractions and are usually benign (head compression); variable decelerations suggest cord compression and need position change; late decelerations follow contractions and signal uteroplacental insufficiency, requiring repositioning, oxygen, and provider notification.
- Forgetting that a boggy uterus with heavy bleeding means uterine atony, the most common cause of postpartum hemorrhage; massage the fundus and notify the provider.
- Confusing pregnancy-induced hypertension with preeclampsia; new hypertension plus proteinuria or end-organ signs is preeclampsia, and magnesium sulfate is used for seizure prophylaxis.
- Missing the danger signs of magnesium toxicity: loss of deep tendon reflexes, respiratory depression, oliguria.
- Underestimating newborn heat loss mechanisms (evaporation, conduction, convection, radiation) and the risk of cold stress.
Rule of thumb
For fetal monitoring, decide first whether the deceleration is early, variable, or late; only late decelerations consistently demand intrauterine resuscitation and escalation.
Worked example
During labor, the fetal heart rate drops to 90 bpm after each contraction and recovers slowly. This is a late deceleration pattern. The nurse should reposition the mother to the left side, give oxygen, increase IV fluids per protocol, stop oxytocin if running, and notify the provider, while continuing to monitor.
