A nurse is caring for a female client, age 30, at 37 weeks of gestation in the labor and delivery unit for blood pressure observation. For each potential provider’s prescription, click to specify if the potential prescription is anticipated or contraindicated for the client.

Administer magnesium sulfate bolus: Anticipated. Magnesium sulfate is the drug of choice to prevent seizures in severe preeclampsia or eclampsia. The client shows signs of severe preeclampsia (hypertension, headache, visual disturbances, hyperreflexia, clonus, epigastric pain), so a magnesium sulfate bolus is appropriate to reduce CNS irritability and prevent eclamptic seizures. Insert an indwelling urinary catheter: Anticipated. Monitoring urine output is essential in hypertensive disorders of pregnancy to assess kidney function and fluid balance. The client’s urine output (25–55 mL/hr) is borderline low (normal >30 mL/hr), so catheter insertion allows accurate measurement. Initiate intravenous (IV) fluids: Contraindicated. In preeclampsia, patients often have intravascular volume depletion with risk of pulmonary edema due to increased capillary permeability. IV fluids should be carefully restricted to avoid fluid overload, so routine IV fluid initiation is contraindicated unless hypovolemia or dehydration is confirmed. Administer nifedipine 30 mg intermittent IV bolus: Contraindicated. Nifedipine, a calcium channel blocker, is given orally for hypertension in pregnancy, but intermittent IV bolus administration is not recommended because it can cause abrupt hypotension and fetal distress. Begin intermittent electronic fetal monitoring: Anticipated. Continuous or intermittent fetal monitoring is critical for detecting fetal distress, especially in high-risk pregnancies with maternal hypertension and irregular contractions, ensuring timely intervention if needed.
