Biochemistry, Genetics, and Cell Biology Practice Question

Question

A professional is deciding the best next action for the USMLE Step 1 involving GI absorption in Biochemistry, Genetics, and Cell Biology. Which option best reduces risk or error? (Item 66)

Answer choices

1. A. Rely on informal custom instead of the applicable rule, control, or standard.
2. B. The best answer is to select the foundational mechanism, diagnosis, or physiologic explanation that best fits the clinical science scenario for the GI absorption scenario.
3. C. Skip verification because the previous case had the same answer.
4. D. Document nothing because documentation could create follow-up questions.

Correct Answer

B. The best answer is to select the foundational mechanism, diagnosis, or physiologic explanation that best fits the clinical science scenario for the GI absorption scenario.

Explanation

The correct answer is B because GI absorption is tested by asking candidates to select the foundational mechanism, diagnosis, or physiologic explanation that best fits the clinical science scenario. The distractors reflect common exam mistakes: ignoring context, using informal shortcuts, skipping verification, or applying a rule from the wrong domain.
