Physiological Adaptation QID 629

When caring for a patient with acute renal failure, the nurse should monitor which laboratory value most closely?

A:
Serum potassium levels.
B:
Blood glucose levels.
C:
White blood cell count.
D:
Serum sodium levels.

Acute renal failure can lead to hyperkalemia (high potassium levels), which is potentially life-threatening. Monitoring serum potassium levels is crucial for these patients. The other laboratory values are also important but are not typically as immediately impacted by acute renal failure.
