Rational drug use and pharmacist’s role MCQs With Answer

Rational drug use and pharmacist’s role MCQs With Answer

This quiz collection is designed for M.Pharm students studying Principles of Quality Use of Medicines (MPP 201T). It focuses on core concepts of rational drug use: principles of appropriate prescribing, essential medicines, prescribing indicators, antimicrobial stewardship, pharmacoeconomics, pharmacovigilance, and systems that support rational therapy. Emphasis is placed on the clinical and public-health roles pharmacists play — from medication review, formulary management, and drug information services to adverse drug reaction reporting, prescription auditing, and patient counselling. These 20 well-crafted multiple-choice questions with answers test both theoretical understanding and applied competencies expected of postgraduate pharmacy professionals in promoting safe, effective and cost-conscious medication use.
