  1. Question 1

    Q1. A 45-year-old hypertensive patient is prescribed a beta-blocker. How does this medication lower blood pressure?

    • A) By increasing cardiac output
    • B) By decreasing peripheral resistance
    • C) By reducing heart rate and contractility
    • D) By increasing venous capacitance

    Answer: By reducing heart rate and contractility

    Explanation: Beta-blockers reduce heart rate and contractility, lowering cardiac output. They do not directly decrease peripheral resistance.
