In a client with suspected pheochromocytoma, which medication should the nurse implement first to manage hypertension?

In managing hypertension in a client with suspected pheochromocytoma, the priority is to effectively control the elevated blood pressure that can lead to serious complications. Nitroprusside is a potent vasodilator that can provide rapid and controlled lowering of blood pressure, making it an appropriate choice for immediate management in a hypertensive crisis associated with pheochromocytoma.

Pheochromocytomas produce catecholamines (e.g., epinephrine and norepinephrine), leading to episodes of severe hypertension. In this context, a fast-acting medication like nitroprusside is essential as it can quickly reduce systemic vascular resistance and lower blood pressure without the lag time that oral medications would require.

Other options listed, such as giving acetaminophen, assessing electrolyte levels, or placing a fan in the room, do not address the urgent need to control severe hypertension. Acetaminophen may be beneficial for symptomatic relief of headaches but does not have any role in managing blood pressure. Drawing labs can be important, but it is not an immediate solution for a hypertensive crisis. Similarly, placing a fan in the room is unrelated to treating hypertension effectively; it may provide comfort but does not address the underlying issue.

Therefore, initiating a nitro
