Rationale: The correct answer is 'Orthostatic hypotension.' Amitriptyline can lead to orthostatic hypotension, a sudden drop in blood pressure when standing up, which can cause dizziness and increase the risk of falls.

Rationale: The correct answer is to instruct the client to avoid salt substitutes. Lisinopril, an ACE inhibitor, can lead to hyperkalemia, so it's essential to avoid salt substitutes that may contain potassium which can further elevate potassium levels.

Correct Answer: C

Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Monitoring and correcting electrolyte imbalances are crucial to prevent adverse effects of digoxin therapy.
