A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding is most concerning?

  • A. Bradycardia
  • B. Muscle weakness
  • C. Peaked T waves on the ECG
  • D. Decreased deep tendon reflexes
Correct Answer: C

Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.
