A nurse is providing discharge teaching to a client who had pre-eclampsia and delivered a healthy newborn.

Which of the following statements by the client indicates an understanding of the teaching?

The correct answer is choice A and E. The nurse should check the client’s blood pressure and magnesium level before giving hydralazine to a client with severe pre-eclampsia who is receiving magnesium sulfate intravenously.

• Choice A is correct because hydralazine is an antihypertensive drug that lowers blood pressure by relaxing blood vessels.The nurse should monitor the client’s blood pressure before and after giving hydralazine to ensure that it is within the target range and to avoid hypotension or rebound hypertension.

• Choice B is wrong because pulse oximetry is not directly related to hydralazine administration or pre-eclampsia.Pulse oximetry measures the oxygen saturation of hemoglobin in the blood and can be affected by factors such as anemia, hypothermia, nail polish, or movement.

The nurse should monitor the client’s pulse oximetry as part of routine care, but it is not a priority before giving hydralazine.

• Choice C is wrong because checking the client’s reflexes is not directly related to hydralazine administration or pre-eclampsia.Reflexes are assessed to monitor for signs of magnesium toxicity, which can cause muscle weakness, respiratory depression, and cardiac arrest.

The nurse should check the client’s reflexes as part of routine care, but it is not a priority before giving hydralazine.

• Choice D is wrong because checking the client’s urine specific gravity is not directly related to hydralazine administration or pre-eclampsia.Urine specific gravity measures the concentration of solutes in the urine and can be affected by factors such as hydration status, renal function, or diuretic use.

The nurse should monitor the client’s urine specific gravity as part of routine care, but it is not a priority before giving hydralazine.

• Choice E is correct because magnesium sulfate is a drug that prevents and treats seizures in women with severe pre-eclampsia or eclampsia.The nurse should monitor the client’s magnesium level before and after giving magnesium sulfate to ensure that it is within the therapeutic range and to avoid magnesium toxicity.

Absence of seizures indicates a therapeutic response to magnesium sulfate therapy for a client with eclampsia.Magnesium sulfate is used to prevent seizures in women with preeclampsia, a complication of pregnancy characterized by high blood pressure and organ dysfunction.Magnesium sulfate may act as a vasodilator, an anticonvulsant, and a protector of the blood-brain barrier.

Choice B is wrong because a decrease in urine output may indicate renal impairment, which is a complication of preeclampsia and eclampsia.

Choice C is wrong because an increase in deep tendon reflexes may indicate hyperreflexia, which is a sign of increased neuromuscular irritability and a risk factor for seizures.

Choice D is wrong because an increase in respiratory rate may indicate respiratory distress, which can be caused by pulmonary edema, another complication of preeclampsia and eclampsia.

Normal ranges for urine output are 0.5 to 1 mL/kg/hour, for deep tendon reflexes are 1+ to 2+, and for respiratory rate are 12 to 20 breaths per minute.
