Question 1 of 5

A patient takes two medications. Drug A is taken once per day; drug B is taken every 8 hours. Which conclusion about drug A is correct?

Correct Answer: C

Rationale: The correct answer is C: Drug A has a longer half-life than drug B. The half-life of a drug is the time it takes for half of the drug to be eliminated from the body. Since drug A is taken once a day compared to drug B taken every 8 hours, drug A must have a longer half-life to maintain therapeutic levels in the body over a 24-hour period. This indicates that drug A stays in the body longer than drug B.

Choice A is incorrect as the therapeutic range is not determined by the dosing frequency.
Choice B is irrelevant to the dosing frequency of the drugs.
Choice D is incorrect as toxicity is not directly related to dosing frequency.
