A patient is breastfeeding and needs analgesia for postpartum pain. Which analgesic is considered safest for the breastfeeding dyad?
Answer: Ibuprofen 600 mg every 6 hours as needed
Ibuprofen is the preferred postpartum analgesic for breastfeeding mothers because it has low transfer into breast milk, does not affect platelet function in the infant, and provides effective pain relief.
A patient with preeclampsia with severe features delivers at 34 weeks. Magnesium sulfate is continued postpartum. For how long is magnesium typically continued after delivery for seizure prophylaxis?
Answer: 24–48 hours postpartum
Magnesium sulfate for seizure prophylaxis is typically continued for 24–48 hours postpartum in preeclampsia with severe features, as the risk for eclamptic seizures persists after delivery.
A newborn requires vitamin K administration. The parents refuse intramuscular injection and ask about oral alternatives. What should the nurse explain about oral vitamin K?
Answer: Oral vitamin K requires multiple doses and provides less reliable protection against late hemorrhagic disease
Oral vitamin K requires multiple doses (at birth, 1 week, and 4–6 weeks) and provides less predictable absorption than IM, resulting in inferior protection against late-onset hemorrhagic disease of the newborn.
A patient requires induction of labor with a cervical ripening agent. Misoprostol (Cytotec) 25 mcg is placed vaginally. Which finding requires the nurse to withhold the next dose?
Answer: Contractions every 2 minutes lasting 90 seconds with incomplete uterine relaxation
Uterine tachysystole with inadequate uterine relaxation indicates excessive response to misoprostol; subsequent doses must be withheld to prevent fetal hypoxia from placental insufficiency.
Indomethacin is prescribed as a tocolytic for a patient at 28 weeks in preterm labor. Which fetal effect must the nurse be aware of with prolonged use?
Answer: Premature closure of the ductus arteriosus
Indomethacin, a prostaglandin synthetase inhibitor, can cause constriction or premature closure of the ductus arteriosus, especially with use beyond 32 weeks or for more than 48 hours.
A patient is to receive dinoprostone (Cervidil) cervical ripening insert. How long should the insert remain in place if no adverse reactions occur?
Answer: 12 hours or until active labor begins
Cervidil (dinoprostone 10 mg) is designed to release prostaglandin slowly over 12 hours; it should be removed at 12 hours, with onset of active labor, or if uterine hyperstimulation or adverse fetal effects occur.
