Biochemistry, Genetics, and Cell Biology Practice Question

Question

A scenario includes a common misconception for the USMLE Step 1 involving GI absorption in Biochemistry, Genetics, and Cell Biology. Which option best reduces risk or error? (Item 146)

Answer choices

1. A. Document nothing because documentation could create follow-up questions.
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. Rely on informal custom instead of the applicable rule, control, or standard.
4. D. Skip verification because the previous case had the same answer.

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.
