  1. Question 1

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

    • A) Blocking the alpha-adrenergic receptors
    • B) Blocking the beta-adrenergic receptors
    • C) Increasing the mucociliary clearance
    • D) Inhibiting the leukotriene synthesis

    Answer: Inhibiting the leukotriene synthesis

    Explanation: Medications that inhibit leukotriene synthesis are effective in treating asthma. Blocking alpha-adrenergic receptors affects peripheral resistance, while blocking beta-adrenergic receptors can have undesirable effects on the heart. Increasing mucociliary clearance is a mechanism of action of certain mucolytics.
