In a hypertensive emergency, which medication should the nurse anticipate administering?

• A. Warfarin (Coumadin)
• B. Furosemide (Lasix)
• C. Sodium nitroprusside (Nitropress)
• D. Ramipril (Altace)

Answer: (C)

In a hypertensive emergency, the primary goal is to rapidly and effectively lower dangerously high blood pressure to prevent end-organ damage. Sodium nitroprusside is a potent vasodilator that works quickly to reduce blood pressure by relaxing the smooth muscles of blood vessels, leading to vasodilation. This medication is typically administered intravenously in a controlled setting, allowing for immediate titration based on the patient’s response. The use of sodium nitroprusside is critical because it can provide immediate hypotensive effects, making it suitable for severe hypertension scenarios such as hypertensive emergencies where the patient may exhibit signs of acute target organ injury, such as encephalopathy, heart failure, or renal failure. Other medications listed do not fulfill the requirement of immediate blood pressure control in a hypertensive emergency. Warfarin is an anticoagulant, which does not address hypertension; furosemide is a diuretic that can help relieve fluid overload but does not directly lower blood pressure rapidly; and ramipril is an ACE inhibitor, which can lower blood pressure over time but is not used for urgent management. Thus, sodium nitroprusside stands out as the appropriate choice in this context.
