Question 1
What is the primary mechanism of action of ACE inhibitors such as lisinopril?
Answer: ACE inhibitors block the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, thereby lowering blood pressure.
Question 2
Which drug classification does warfarin (Coumadin) belong to, and what clotting factors does it inhibit?
Answer: Warfarin is an anticoagulant that inhibits vitamin K-dependent clotting factors II, VII, IX, and X.
Question 3
What class of drugs are SSRIs, and what is their primary mechanism of action?
Answer: SSRIs (Selective Serotonin Reuptake Inhibitors) are antidepressants that block the reuptake of serotonin into the presynaptic neuron, increasing serotonin availability in the synapse.
Question 4
What is the mechanism of action of loop diuretics such as furosemide (Lasix)?
Answer: Loop diuretics inhibit the Na-K-2Cl cotransporter in the thick ascending loop of Henle, preventing sodium and water reabsorption and producing potent diuresis.
Question 5
Beta-1 selective adrenergic blockers primarily affect which organ, and what is the clinical result?
Answer: Beta-1 selective blockers (e.g., metoprolol, atenolol) primarily affect the heart, reducing heart rate, contractility, and blood pressure.
