Question

The client has been diagnosed with pheochromocytoma. Which finding supports a diagnosis of pheochromocytoma? A. Malignant hypertension B. Anorexia C. Urinary frequency D. Bronze pigmentation of the skin

Short answer

Answer: Malignant Hypertension.

Step-by-step solution

Understanding Pheochromocytoma

Pheochromocytoma is a rare, usually benign tumor that develops in the adrenal glands. These tumors can produce excessive amounts of catecholamines (such as adrenaline and norepinephrine), which can lead to symptoms such as high blood pressure, rapid heartbeat, sweating, and anxiety.

Evaluating Option A - Malignant Hypertension

Malignant hypertension, also known as a hypertensive crisis, is a severe form of high blood pressure that can be life-threatening. Since pheochromocytomas can produce excessive amounts of catecholamines, which can lead to high blood pressure, this option is consistent with a diagnosis of pheochromocytoma.

Evaluating Option B - Anorexia

Anorexia refers to a reduced appetite or an aversion to eating. While some patients with pheochromocytoma may experience weight loss or changes in appetite, this finding is not specific enough to support a diagnosis of pheochromocytoma.

Evaluating Option C - Urinary Frequency

Urinary frequency refers to the need to urinate more often than usual. This symptom is not typically associated with pheochromocytoma and does not support a diagnosis of the condition.

Evaluating Option D - Bronze Pigmentation of the Skin

Bronze pigmentation of the skin is not typically associated with pheochromocytoma. It is more commonly seen in conditions such as Addison's disease or hemochromatosis.

Determining the Correct Answer

Based on the analysis of each option, the finding that supports a diagnosis of pheochromocytoma is Option A: Malignant Hypertension. High blood pressure due to excessive catecholamine production is a characteristic feature of this condition.
