1. Hyperkalemia
2. Hyponatremia
3. Hypernatremia
4. Hypokalemia
Correct Answer: 1

Rationale 2: Lisinopril therapy does not increase the risk of hyponatremia.
Rationale 3: Lisinopril therapy does not increase the risk of hypernatremia.
Rationale 4: Lisinopril therapy does not increase the risk of hypokalemia, but of hyperkalemia.
Global Rationale: Lisinopril therapy can increase the risk of hyperkalemia because it is a potassium-sparing drug. Clients with heart failure are at higher risk. Lisinopril therapy does not increase the risk of hyponatremia, hypernatremia, or hypokalemia.
