Which nursing action is contraindicated in pheochromocytoma because it can trigger a catecholamine surge?

• A. Palpate the abdomen.
• B. Elevate the head of the bed.
• C. Monitor blood pressure closely.
• D. Administer IV fluids as ordered.

Answer: (A)

In pheochromocytoma, the adrenal tumor can release large amounts of catecholamines. Manipulating the tumor or surrounding tissues—such as palpating the abdomen—can trigger a sudden surge of these substances, precipitating a hypertensive crisis with tachycardia and potential complications. That makes abdominal palpation contraindicated. Other safe actions to support stability include elevating the head of the bed to help reduce blood pressure, closely monitoring blood pressure, and administering IV fluids as ordered to maintain intravascular volume.
