Question 1 (MCQ)
Clinical Scenario
A nursing student asks why no medication can be considered
completely safe for every patient.
Question Stem
Which property of drugs best explains why all medications have
the potential to cause harm?
Answer Options
A. Drugs produce only therapeutic effects
B. Drugs cannot distinguish between therapeutic and
nontherapeutic targets
C. All drugs affect only diseased tissues
D. Drug effects occur only at prescribed doses
Correct Answer
B. Drugs cannot distinguish between therapeutic and
nontherapeutic targets
Detailed Rationale
,No medication is completely selective. Even highly targeted
drugs may interact with unintended receptors, tissues, or
physiologic pathways. Because drugs cannot perfectly
distinguish between desired and undesired targets, adverse
effects can occur alongside therapeutic effects. This principle
underlies the need for monitoring, patient education, and risk-
benefit evaluation.
Incorrect Option Analysis
A
• Incorrect because drugs may produce adverse effects.
• Misconception: Therapeutic effects occur without risk.
• Safety Risk: Failure to monitor complications.
• Nursing Consideration: Monitor for intended and
unintended effects.
C
• Incorrect because drugs affect healthy tissues as well.
• Misconception: Medication acts only where disease exists.
• Safety Risk: Missed adverse reactions.
• Nursing Consideration: Assess systemic responses.
D
, • Incorrect because adverse effects may occur at prescribed
doses.
• Misconception: Correct dose guarantees safety.
• Safety Risk: Delayed recognition of toxicity.
• Nursing Consideration: Monitor patient response
regardless of dose.
