Final answer:
Misoprostol is contraindicated for a patient at 32 weeks of gestation who is in labor, as it is a labor-inducing medication not typically used before 37 weeks. Other listed medications have different uses during pregnancy: folic acid prevents neural tube defects, nifedipine and terbutaline sulfate can be used to suppress preterm labor.
Step-by-step explanation:
The nurse is caring for a client who is at 32 weeks of gestation and in labor. Among the listed medications, misoprostol is contraindicated for this patient. Misoprostol is a medication that can induce labor and is not typically used before 37 weeks of gestation due to risks of preterm birth and complications for the infant. In contrast, folic acid is often recommended during pregnancy to prevent neural tube defects; nifedipine may be used for tocolysis, which is the suppression of preterm labor; and terbutaline sulfate might also be used as a tocolytic agent to delay preterm labor, although it is less commonly used due to potential side effects.
It's important to note that the hormone oxytocin is primarily responsible for contractions during labor. Before the baby and the placenta are expelled, there are several stages of labor that occur, including the dilation of the cervix and the rupture of the amniotic sac. If labor is not progressing naturally, as in Janine's case at 41 weeks of gestation, an IV infusion of pitocin, which is a synthetic form of oxytocin, may be started to induce or augment contractions and aid in the progression of labor.
