During admission assessment for pheochromocytoma, which action best assesses the major sign?

• A. Obtaining the client's weight
• B. Taking the client's blood pressure
• C. Testing the client's urine for glucose
• D. Palpating the skin for its temperature

Answer: (B)

Pheochromocytoma causes excess catecholamine release, with hypertension being the most consistent and characteristic finding. The major sign to assess is elevated blood pressure, as it directly reflects the tumor’s effect on vascular tone and cardiac output. During admission, taking multiple blood pressure readings helps identify sustained or paroxysmal hypertension, which is central to recognizing this condition.

Other options don’t directly assess the primary manifestation. Weighing the patient doesn’t reveal the cardiovascular impact, testing urine for glucose looks for metabolic issues rather than the tumor’s vascular effects, and palpating skin temperature isn’t a reliable indicator of pheochromocytoma. Monitoring blood pressure remains the most informative initial assessment.
