Extract:


Question 1 of 5

Narrow therapeutic index medications:

Correct Answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity.
Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index.
Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety.
Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.
