beta-blockers in the treatment of hypertension?
a) Inhibition of angiotensin-converting enzyme
b) Blockade of beta-adrenergic receptors
c) Stimulation of alpha-adrenergic receptors
d) Inhibition of calcium channels
- Correct ANS: b) Blockade of beta-adrenergic receptors
, - Rationale: Beta-blockers reduce blood pressure by blocking
beta-adrenergic receptors, which decreases heart rate and cardiac
output.
2. Which of the following is a common side effect of
angiotensin-converting enzyme (ACE) inhibitors?
a) Hyperkalemia
b) Hypokalemia
c) Hypernatremia
d) Hyponatremia

statins in the management of hyperlipidemia?
a) Inhibition of cholesterol absorption
b) Inhibition of HMG-CoA reductase
c) Stimulation of lipoprotein lipase
d) Inhibition of bile acid reabsorption
- Correct ANS: b) Inhibition of HMG-CoA reductase
- Rationale: Statins lower cholesterol levels by inhibiting
HMG-CoA reductase, an enzyme involved in cholesterol
synthesis.
5. Which of the following is a common adverse effect of
corticosteroid therapy?
a) Hypoglycemia
b) Osteoporosis
