, - Rationale: Beta-blockers work by blocking adrenergic
receptors, which reduces heart rate and blood pressure.


2. What is the primary use of ACE inhibitors in clinical practice?
- A. Treating hyperlipidemia
- B. Managing hypertension
- C. Controlling diabetes
- D. Reducing inflammation

- A. Increasing cardiac output
- B. Reducing fluid volume
- C. Enhancing myocardial contractility
- D. Lowering blood glucose levels
- ANS: B. Reducing fluid volume
- Rationale: Diuretics help reduce fluid volume in the body,
which decreases the workload on the heart in patients with heart
failure.


5. Which of the following is an example of a selective serotonin
reuptake inhibitor (SSRI)?
