What is an appropriate nursing intervention related to maternal blood pressure when using hydralazine?

• A. Increase fluid intake
• B. Avoid all movement
• C. Maintain a stable diastolic blood pressure
• D. Immediate cessation of all medications

Answer: (C)

Maintaining a stable diastolic blood pressure is crucial when administering hydralazine, as this medication is used to treat hypertension during pregnancy. Hydralazine works as a vasodilator, effectively lowering blood pressure by relaxing the blood vessels. However, it is essential to monitor and stabilize diastolic blood pressure to prevent potential complications, such as placental insufficiency or fetal distress, which can occur if blood pressure drops too low. Stabilizing diastolic blood pressure ensures that blood flow to the placenta remains adequate, promoting both maternal and fetal well-being. This intervention also supports the physiological adaptations necessary during pregnancy, where maintaining an optimal blood pressure is vital for ensuring proper perfusion to maternal organs and placental function. In contrast, increasing fluid intake may be helpful in certain circumstances to support blood pressure but does not directly address the management of hypertension. Avoiding all movement is impractical and could lead to other complications related to decreased mobility. Immediate cessation of all medications may result in a rapid increase in blood pressure, which is dangerous and counterproductive to the treatment goals. Therefore, focusing on maintaining a stable diastolic blood pressure is a safe and effective nursing intervention when managing a patient on hydralazine.
