A client with pheochromocytoma is receiving preoperative care. Which finding requires the nurse to take immediate action?

Pheochromocytoma can release excess catecholamines and cause a hypertensive crisis. A sudden pounding headache, sweating, palpitations, and severe hypertension signal dangerous cardiovascular stress requiring immediate intervention. The other findings do not show the same acute crisis pattern.

Quick answer
Treat the sudden headache, sweating, palpitations, and severe hypertension as a catecholamine crisis requiring immediate action.

Why this is correct
A pheochromocytoma can discharge large amounts of catecholamines, producing abrupt vasoconstriction and cardiac stimulation. The combined symptom cluster signals a hypertensive crisis that can progress to dysrhythmia, myocardial infarction, stroke, or death.

Easy analogy or mental picture
A catecholamine surge is like an accelerator and pressure valve failing at the same time: heart drive and vascular pressure rise together. The comparison shows urgency, but treatment must follow the monitored medical plan.

Memory hook
Pheochromocytoma crisis cluster: pounding head, sweat, racing heart, severe pressure.

NCLEX decision rule
For a client with pheochromocytoma, prioritize an abrupt cluster of severe hypertension, headache, sweating, and palpitations as a cardiovascular emergency. Compare the whole acute pattern rather than reacting to one mild expected medication effect.

Why the other choices are wrong
Mild nasal congestion or positional lightheadedness can occur with alpha blockade and still requires routine assessment. Brief fatigue or reduced appetite does not match the sudden catecholamine-driven hypertensive crisis pattern.

Clinical Practice Guide
For Stroke dysphagia screening, compare the complete cue pattern with the client's current stability, ordered data, and expected nursing scope.

Caution
Do not choose an action from one isolated cue when the full scenario changes priority or safety.
