The nurse cares for a client with a potassium of 3.2 mEq/L (mmol/L) [3.5-5 mEq/L, mmol/L]. Which of the following medications may cause this abnormality?
- A. spironolactone
- B. triamterene
- C. prednisone
- D. lisinopril
Correct Answer: B
Rationale: Triamterene is a potassium-sparing diuretic that can cause hypokalemia by reducing potassium excretion. Spironolactone (A) also spares potassium but is less likely to cause hypokalemia. Prednisone (C) primarily affects glucose and sodium, not potassium. Lisinopril (D) may cause hyperkalemia, not hypokalemia.

- A. Headache and increased urinary output
- B. Weight gain and edema
- C. Hypertension and decreased urinary output

- A. Dicyclomine
- B. Ipratropium
- C. Oxybutynin

The nurse reviews a client's laboratory results and notes the potassium level is 5.6 mEq/L (mmol/L) [3.5-5 mEq/L, mmol/L]. Which change to the cardiac rhythm would be expected?
- A. Tall, peaked T waves
- B. ST segment elevation
- C. Peaked P waves
- D. Noticeable U waves
Correct Answer: A
Rationale: Hyperkalemia causes tall, peaked T waves due to altered cardiac repolarization.
The nurse is caring for a client in the medical-surgical unit. The nurse is reviewing the client's laboratory data and should take which action.
