A nurse is caring for a client who is 36 weeks of gestation and experiences a spontaneous rupture of membranes. Which of the following actions should the nurse take?

Rationale: A. Administer magnesium sulfate to the client: Magnesium sulfate is typically used for neuroprotection before 32 weeks or to manage preeclampsia; it is not indicated for rupture of membranes at 36 weeks unless there are other risk factors. B. Administer betamethasone to the client: Betamethasone is used to enhance fetal lung maturity, most beneficial before 34 weeks. At 36 weeks, the lungs are usually mature enough that corticosteroids are not routinely indicated. C. Monitor the client's temperature every 2 hr: This helps detect early signs of chorioamnionitis, a serious infection risk after membrane rupture, especially with prolonged rupture. D. Monitor fetal heart rate every 4 hr: Fetal heart monitoring should be more frequent in the presence of membrane rupture to promptly identify signs of distress or infection, not every 4 hours.
