, Question 1: What is the mechanism of action for beta-blockers?
• A) Increase heart rate
• B) Inhibit norepinephrine from binding to beta-adrenergic receptors
• C) Enhance insulin secretion
• D) Decrease renal blood flow
Correct Option: B) Inhibit norepinephrine from binding to beta-adrenergic
receptors
Rationale: Beta-blockers work by blocking the action of norepinephrine on beta-
adrenergic receptors, which leads to decreased heart rate and contractility. This action
makes them effective in treating conditions such as hypertension, heart failure, and
anxiety.
Question 2: Which class of drugs is primarily used as anticoagulants?
• A) NSAIDs
• B) Beta-blockers
• C) Antiplatelet agents
• D) Warfarin
Correct Option: D) Warfarin
Rationale: Warfarin is an anticoagulant that works by inhibiting vitamin K epoxide
reductase, which is essential for the synthesis of certain clotting factors. It is commonly
used to prevent thrombosis and embolism in patients with conditions like atrial
fibrillation and deep vein thrombosis.
Question 3: What is the primary use of ACE inhibitors?
• A) Pain relief
• B) Management of hyperlipidemia
• C) Treatment of hypertension
• D) Antidepressant therapy
Correct Option: C) Treatment of hypertension
Rationale: ACE inhibitors (Angiotensin-Converting Enzyme inhibitors) are primarily
used to treat hypertension by preventing the conversion of angiotensin I to angiotensin
II, a potent vasoconstrictor. This results in vasodilation and decreased blood pressure,
making them effective for managing hypertension and heart failure.
