. A client is admitted to the health care facility for evaluation for Addison’s disease. Which laboratory test result best supports a diagnosis of Addison’s disease?

  • A. Blood urea nitrogen (BUN) level of
  • B. Serum sodium level of 134 mEq/L
  • C. Serum potassium level of 5.8 mEq/L
  • D. Blood glucose level of 90 mg/dl
Correct Answer: C

Rationale: Step-by-step rationale for choice C (Serum potassium level of 5.8 mEq/L) being the best to support a diagnosis of Addison's disease:
1. Addison's disease is characterized by adrenal insufficiency, leading to decreased aldosterone secretion.
2. Decreased aldosterone causes hyperkalemia due to impaired potassium excretion.
3. Elevated serum potassium levels above the normal range (3.5-5.0 mEq/L) are a classic finding in Addison's disease.
4. Therefore, a serum potassium level of 5.8 mEq/L strongly supports the diagnosis of Addison's disease.

Summary:
- Choice A (BUN level): BUN is not specific to Addison's disease and does not directly relate to adrenal function.
- Choice B (Serum sodium level): Hyponatremia is a common finding in Addison's disease, but it is not as specific as hyperkalemia.
- Choice D (Blood glucose level): Blood glucose
