yeah C is correct
This pt has pheochromocytoma, a chromaffin cell tumor in adrenal medulla. Hypersecretion of catecholamines results in HTN, severe H/A, sweating, heart palpitations, angina and anxiety. If pt were given phentolamine, an adrenergic blocker, a marked decrease in BP would be ntoed. A beta adrenergic blocker such as propanolol would be used to reduce tachycardia. In most pts, the tumors secrete predominantly NE
