A nurse is caring for a client with gestational hypertension who is at risk for developing preeclampsia.

Which of the following interventions should the nurse implement to prevent this complication? (Select all that apply.).

The correct answer is choice B. Monitor fetal heart rate continuously.This is because hydralazine is a vasodilator that lowers blood pressure and may cause tachycardia.Tachycardia can affect the fetal heart rate and oxygenation, so continuous monitoring is essential to detect any signs of fetal distress.

Choice A is wrong because hydralazine does not cause orthostatic hypotension, but rather a reflex increase in heart rate and cardiac output.

Orthostatic hypotension is more likely to occur with other antihypertensive drugs such as alpha-blockers or diuretics.

Choice C is wrong because encouraging oral fluid intake may worsen the fluid retention and edema that are common in preeclampsia.Fluid intake should be restricted to avoid pulmonary edema and cerebral edema.

Choice D is wrong because administering oxygen via nasal cannula is not a priority intervention for a woman with severe preeclampsia who is receiving hydralazine IV.Oxygen therapy may be indicated if the woman develops signs of hypoxia, such as dyspnea, cyanosis, or low oxygen saturation.However, oxygen therapy should be used with caution as it may increase oxidative stress and placental vasoconstriction.

The correct answer is choice C) “I should report any dizziness or lightheadedness while taking this medication.” This is because labetalol can lower blood pressure and cause orthostatic hypotension, which can lead to falls and injuries.The patient should be advised to change positions slowly and monitor their blood pressure regularly while taking labetalol.

Choice A is wrong because labetalol can be taken with or without food.Taking it on an empty stomach does not affect its absorption or efficacy.

Choice B is wrong because labetalol does not affect potassium levels in the blood.Foods high in potassium are not contraindicated while taking this medication.

Choice D is wrong because swelling in the feet or hands can be a sign of worsening preeclampsia, which is a serious complication of hypertension in pregnancy.The patient should not stop taking labetalol without consulting their doctor, as this can cause rebound hypertension and endanger the mother and the fetus.The patient should seek medical attention if they experience swelling, headache, vision changes, abdominal pain, or reduced fetal movements.
