The nurse cares for a client with a potassium of 3.1 mEq/L (mmol/L) [3.5-5 mEq/L, mmol/L]. The primary healthcare provider (PHCP) prescribed 40 mEq of intravenous (IV) potassium over four hours. Which assessment finding would indicate a therapeutic effect?

  • A. normoactive bowel sounds
  • B. flattened T-waves
  • C. reduced deep tendon reflexes
  • D. muscle cramping
Correct Answer: B

Rationale: Hypokalemia can cause peaked T-waves on ECG. A therapeutic effect of potassium administration would be normalization of ECG, indicated by flattened T-waves. Normoactive bowel sounds (A), reduced reflexes (C), and muscle cramping (D) are not specific indicators of corrected hypokalemia.
