  1. Question 1

    Q1. A patient has been prescribed a medication to treat hypertension. What is the mechanism of action of this medication?

    • A) Blocking the alpha-adrenergic receptors
    • B) Blocking the beta-adrenergic receptors
    • C) Inhibiting the renin-angiotensin-aldosterone system
    • D) Increasing the parasympathetic tone

    Answer: Inhibiting the renin-angiotensin-aldosterone system

    Explanation: Medications that inhibit the renin-angiotensin-aldosterone system are effective in lowering blood pressure. Blocking alpha-adrenergic receptors affects peripheral resistance, while blocking beta-adrenergic receptors can have undesirable effects. Increasing parasympathetic tone is a mechanism of action of certain anticholinesterases.
