A nurse is admitting a client who has a diagnosis of preterm labor. The nurse anticipates an order by the provider for which of the following medications?

Choice A reason: Primigravida in spontaneous labor with preterm twins is not at the greatest risk for early postpartum hemorrhage, as preterm births are associated with lower blood loss and smaller placentas. However, this client may have other complications, such as preterm labor, premature rupture of membranes, or fetal growth restriction.

Choice B reason: Primiparous woman (G 2, P 1-0-0-1) being prepared for an emergency cesarean birth for fetal distress is not at the greatest risk for early postpartum hemorrhage, as cesarean births are associated with higher blood loss and larger incisions. However, this client may have other complications, such as infection, wound dehiscence, or thromboembolism.

Choice C reason: Multiparous woman (G 3, P 2-0-0-2) with an 8-hour labor is at the greatest risk for early postpartum hemorrhage, as multiparity and rapid labor are both risk factors for uterine atony, which is the most common cause of early postpartum hemorrhage. Uterine atony is a condition where the uterus fails to contract and retract after delivery, and can cause excessive bleeding and hypovolemic shock.

Choice D reason: Woman with severe preeclampsia on magnesium sulfate whose labor is being induced is not at the greatest risk for early postpartum hemorrhage, as preeclampsia and magnesium sulfate are both risk factors for late postpartum hemorrhage, which occurs after 24 hours of delivery. However, this client may have other complications, such as eclampsia, HELLP syndrome, or placental abruption.

Choice A reason: Calcium carbonate is not the compound that the nurse should have readily available, as it is an antacid that neutralizes stomach acid and relieves heartburn. Calcium carbonate is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.

Choice B reason: Potassium chloride is not the compound that the nurse should have readily available, as it is an electrolyte supplement that replenishes potassium levels and prevents hypokalemia. Potassium chloride is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.

Choice C reason: Ferrous sulfate is not the compound that the nurse should have readily available, as it is an iron supplement that prevents or treats iron deficiency anemia. Ferrous sulfate is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.

Choice D reason: Calcium gluconate is the compound that the nurse should have readily available, as it is an antidote that reverses the effects of magnesium sulfate and restores calcium levels and neuromuscular function. Calcium gluconate is used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.
