Question 1 of 5
What drug enhances the output of respiratory tract fluid by reducing the adhesiveness and surface tension of the fluid which facilitates the removal of viscous mucus?
Correct Answer: A
Rationale: The correct answer is A: Guaifenesin. Guaifenesin is an expectorant that works by increasing respiratory tract fluid output, reducing adhesiveness and surface tension of the mucus. This helps in loosening and thinning the mucus, making it easier to clear from the airways. Dextromethorphan (
B) is a cough suppressant, not an expectorant. Acetylcysteine (
C) is a mucolytic that reduces mucus thickness but does not directly enhance fluid output. Flunisolide (
D) is a corticosteroid used for inflammation, not mucus clearance.
