A nurse is assisting in the care of a client who is at 36 weeks of gestation and is in preterm labor. The nurse should expect a prescription for which of the following medications for the client?

Rationale: A. Oxytocin: Oxytocin is a uterotonic agent used to stimulate or augment labor, not to stop it. In the case of preterm labor at 36 weeks, administering oxytocin would worsen the situation by increasing uterine contractions and promoting delivery, which is not the intended goal. B. Misoprostol: Misoprostol is typically used to induce labor by softening the cervix and stimulating contractions. It is contraindicated in clients experiencing preterm labor, as it would enhance uterine activity and could lead to premature delivery. C. Magnesium sulfate: Magnesium sulfate is used in preterm labor to provide neuroprotection to the fetus and may also help reduce uterine contractions. It is especially indicated when labor is expected before 32–34 weeks but may still be prescribed at 36 weeks depending on clinical judgment. D. Indomethacin: Indomethacin is a tocolytic agent used to suppress preterm labor contractions, but it is generally used before 32 weeks due to the risk of premature closure of the ductus arteriosus. At 36 weeks, the risks may outweigh the benefits, so it is not the first-line option at this gestational age.
