Maternal Newborn Nursing Test Pharmacology in Maternal-Newborn Nursing 3

Question 1

A patient is breastfeeding and needs analgesia for postpartum pain. Which analgesic is considered safest for the breastfeeding dyad?

Accepted Answer

Ibuprofen 600 mg every 6 hours as needed

Answer

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.

Question 2

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?

Accepted Answer

24–48 hours postpartum

Answer

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.

Question 3

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?

Accepted Answer

Oral vitamin K requires multiple doses and provides less reliable protection against late hemorrhagic disease

Answer

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.

Question 4

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?

Accepted Answer

Contractions every 2 minutes lasting 90 seconds with incomplete uterine relaxation

Answer

Uterine tachysystole with inadequate uterine relaxation indicates excessive response to misoprostol; subsequent doses must be withheld to prevent fetal hypoxia from placental insufficiency.

Question 5

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?

Accepted Answer

Premature closure of the ductus arteriosus

Answer

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.
