A nurse is caring for a client with a pheochromocytoma. Which assessment finding will the nurse expect for this client?
Decreased pulse
Elevated blood pressure
Cold intolerance
Decreased respiratory rate
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 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.
Correct Answer is D
Explanation
Rationale:
A. Hypertension can be a symptom of many conditions and is not specific to HHS.
B. Fruity breath is typically associated with diabetic ketoacidosis (DKA) due to the presence of acetone, not HHS.
C. Ketosis is a key feature of DKA, not HHS. In HHS, ketosis is usually absent or minimal.
D. A glucose level of 650 mg/dL is indicative of HHS, which is characterized by extremely high blood glucose levels without significant ketosis. HHS often occurs in type 2 diabetes and is marked by severe hyperglycemia, dehydration, and altered mental status.
