A nurse is caring for a client with a pheochromocytoma. Which assessment finding will the nurse expect for this client?

A.

Decreased pulse

B.

Elevated blood pressure

C.

Cold intolerance

D.

Decreased respiratory rate

Answer and Explanation

The Correct Answer is B

Rationale:

 

A. A decreased pulse is not typically associated with pheochromocytoma. This condition is characterized by the excessive release of catecholamines, which usually leads to an increased heart rate.

 

B. Pheochromocytoma is a tumor of the adrenal medulla that causes excessive secretion of catecholamines, leading to episodic or sustained hypertension. Elevated blood pressure is a hallmark symptom of this condition.

 

C. Cold intolerance is more commonly associated with hypothyroidism and is not a typical finding in pheochromocytoma.

 

D. Decreased respiratory rate is not characteristic of pheochromocytoma; instead, clients may experience symptoms such as palpitations, sweating, and headaches due to the elevated catecholamine levels.

Correct Answer is C

Explanation

Rationale:

A. Examining feet daily is important for preventing foot complications, such as ulcers, in diabetics but is not directly related to preventing retinopathy and nephropathy.

B. Wearing compression stockings is not specifically recommended for preventing retinopathy or nephropathy in diabetes.

C. Maintaining stable blood glucose levels is crucial for preventing or slowing the progression of diabetic complications such as retinopathy and nephropathy. Good glycemic control minimizes the damage to blood vessels in the eyes and kidneys.

D. While regular eye exams are important for detecting retinopathy early, maintaining stable blood glucose levels is key to preventing the development of complications in the first place.

Correct Answer is B

Explanation

Rationale:

A. During the oliguric phase of acute kidney injury, BUN and creatinine levels typically increase due to reduced kidney function, not decrease.

B. The oliguric phase is characterized by significantly reduced urine output, often defined as less than 400 mL per 24 hours, indicating severe kidney impairment.

C. The GFR does not recover during the oliguric phase; it is significantly decreased, contributing to the accumulation of waste products in the blood.

D. Renal function is not reestablished during the oliguric phase; this occurs in later stages, such as the diuretic or recovery phase.
