EKG Question #8


Following treatment for hyperkalemia, the nurse evaluates the electrocardiogram (ECG). What outcome findings will the nurse expect to document?


  1. Client continues to be in hyperkalemic state due to arrythmia
    • Rationale:
  2. The client progressed to a first degree heart block
    • Rationale:
  3. Widened QRS and peaked T waves resolved
    • Rationale:
  4. Administer 20 mEq potassium IV since now there is hypokalemia
    • Rationale:



After treating the hyperkalemia, the ECG changes such as widened QRS, prolonged PR interval, and peaked T waves are expected to subside indicating resolution of the electrolyte imbalance. The ECG strip does not indicate an arrhythmia, first degree heart block, or signs of low potassium.
