A nurse is caring for a client who has a hyperkalemia and is receiving insulin therapy. Which of the following should the nurse recognize as an adverse outcome?
Serum potassium 4.8 mEq/L (3.5 to 5.0 mEq/L)
Serum sodium 138 mEq/L (136 to 145 mEq/L)
Calcium level of 10.0 mg/dL (9.0 to 10.5 mg/dL)
Serum glucose 58 mg/dL (74 to 106 mg/dL)
The Correct Answer is D
A. Serum potassium 4.8 mEq/L (3.5 to 5.0 mEq/L): A normal potassium level suggests effective treatment of hyperkalemia.
B. Serum sodium 138 mEq/L (136 to 145 mEq/L): This is within the normal sodium range and unrelated to the adverse effects of insulin therapy.
C. Calcium level of 10.0 mg/dL (9.0 to 10.5 mg/dL): This is within the normal calcium range, unaffected by insulin therapy for hyperkalemia.
D. Serum glucose 58 mg/dL (74 to 106 mg/dL): Hypoglycemia is a potential adverse effect of insulin therapy because insulin drives glucose into cells, lowering blood sugar.

Correct Answer is B
Explanation
A. Has no peak: NPH insulin has a distinct peak time, unlike long-acting insulins such as glargine or detemir, which have no peak.
B. 4 to 14 hr: NPH insulin is an intermediate-acting insulin with an onset of 1-2 hours, a peak between 4-14 hours, and a duration of 16-24 hours.
C. 1 to 5 hr: This timeframe describes the peak of short-acting insulins such as regular insulin.
D. 30 min to 3 hr: This timeframe describes the peak of rapid-acting insulins such as lispro, aspart, or glulisine.
