Critical Care Registered Nurse (CCRN) Practice Exam

What drug is commonly administered to manage hypertension in patients with Reversible Cerebral Vasoconstriction Syndrome (RCVS)?

1. Aspirin

2. Hydralazine

3. Codeine

4. Phenobarbital

The correct answer is: Hydralazine

Hydralazine is a direct vasodilator that effectively lowers blood pressure, making it a suitable choice for managing hypertension in patients with Reversible Cerebral Vasoconstriction Syndrome (RCVS). RCVS is characterized by episodes of severe headache and is associated with increased blood pressure levels. Since managing hypertension is critical to prevent further complications, hydralazine can help achieve rapid control of the blood pressure when standard oral medications are insufficient. In contrast, aspirin is primarily an antiplatelet agent and does not directly treat hypertension, which may not address the immediate concern of elevated blood pressure in RCVS patients. Codeine, an opioid analgesic, is used for pain management rather than blood pressure control and would not contribute to the treatment of hypertension. Lastly, phenobarbital is primarily used as an anticonvulsant or sedative, not for managing blood pressure, hence it would not be appropriate in this context.
