A nurse is planning to administer hydralazine to a client with severe pre-eclampsia who is receiving magnesium sulfate intravenously.

Which of the following actions should the nurse take before giving the medication? (Select all that apply.)

“You may feel warm and flushed while receiving this medication.” This is a common side effect of magnesium sulfate therapy, which is used to prevent seizures in women with severe pre-eclampsia.Magnesium sulfate can also help prolong a pregnancy for up to two days by relaxing the uterus.

Choice B is wrong because magnesium sulfate can cause fluid retention and swelling, not dehydration.Choice C is wrong because magnesium sulfate can cause drowsiness and lethargy, not insomnia and restlessness.Choice D is wrong because magnesium sulfate can cause decreased blood pressure and heart rate, not inflammation and infection at the infusion site.

Normal ranges for blood pressure are below 140/90 mm Hg, for platelet count are 150,000 to 450,000 per microliter of blood, and for protein in urine are less than 300 milligrams per day.

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.
