Question 1

Which drug class is the first-line treatment for type 2 diabetes mellitus in most patients without contraindications?

Accepted Answer

Metformin (biguanide)

Answer

Metformin is the first-line pharmacological treatment for type 2 diabetes due to its efficacy, safety profile, low cost, and cardiovascular benefits.

Question 2

A patient with hypertension also has heart failure with reduced ejection fraction (HFrEF). Which antihypertensive class provides the greatest mortality benefit?

Accepted Answer

ACE inhibitors or ARBs

Answer

ACE inhibitors (or ARBs if ACE-intolerant) are first-line for HFrEF due to proven mortality reduction by blocking the renin-angiotensin-aldosterone system.

Question 3

Which beta-blocker is considered cardioselective due to its preferential beta-1 receptor blockade?

Accepted Answer

Metoprolol succinate

Answer

Metoprolol succinate is cardioselective, primarily blocking beta-1 receptors in the heart with less effect on beta-2 receptors in the lungs, making it safer in patients with mild asthma.

Question 4

Which anticoagulant is first-line for the initial and long-term treatment of venous thromboembolism (VTE) in most patients?

Accepted Answer

Direct oral anticoagulants (DOACs) such as rivaroxaban or apixaban

Answer

DOACs (e.g., rivaroxaban, apixaban) are preferred for VTE treatment due to their predictable pharmacokinetics, fewer interactions, and no need for routine monitoring.

Question 5

Albuterol is a short-acting beta-2 agonist (SABA) used for acute bronchospasm. Its primary mechanism is:

Accepted Answer

Stimulating beta-2 receptors to relax bronchial smooth muscle

Answer

Albuterol selectively activates beta-2 adrenergic receptors on bronchial smooth muscle, causing relaxation and bronchodilation through increased cAMP.
