A nurse notes that a client's serum potassium level is 5.9 mEq/L. The nurse interprets this as an expected finding in the client with:
Diabetic ketoacidosis
Heart failure being treated with furosemide
Addison disease
Cushing disease
The Correct Answer is C
Choice A rationale: Typically associated with potassium depletion rather than elevated levels.
Choice B rationale: Furosemide, a loop diuretic, can cause potassium depletion leading to hypokalemia, but it might also cause transient elevations in potassium levels initially. Choice C rationale: Addison disease can cause hyperkalemia, or high potassium, due to decreased renal excretion of potassium and increased retention of sodium and water.
Choice D rationale: Cushing disease can cause hypokalemia, or low potassium, due to increased renal excretion of potassium and decreased reabsorption of sodium and water.

Correct Answer is D
Explanation
Choice A rationale: This is a sign of worsening diabetes insipidus.
Choice B rationale: This shows signs of overhydration, as urine output is high and specific gravity is high.
Choice C rationale: This is a sign of worsening diabetes insipidus.
Choice D rationale: Vasopressin is a hormone that helps the kidneys retain water and concentrate urine. Diabetes insipidus is a condition where the body does not produce enough vasopressin or does not respond to it, resulting in excessive urination and diluted urine. The goal of vasopressin therapy is to reduce urine output and increase urine concentration, which indicates that the kidneys are functioning properly and the body is hydrated.
