Rationale: Enalapril, an ACE inhibitor, can lead to hypotension, particularly following the initial dose or dosage escalation. This effect is due to the medication's mechanism of action in dilating blood vessels, which can result in lowered blood pressure. Monitoring for hypotension is crucial to prevent complications such as dizziness, lightheadedness, or fainting in clients taking enalapril.
