What this question is testing
Objective: Medical nutrition therapy for diabetes
Prompt focus: A registered dietitian counsels a patient with type 2 diabetes whose hemoglobin A1c is 8.5 percent. Hemoglobin A1c primarily reflects which of the following?
Why the correct answer works
Average blood glucose control over approximately the prior 2 to 3 months
Correct. Hemoglobin A1c reflects average blood glucose control over approximately the prior two to three months.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
Hemoglobin A1c reflects the percentage of glycated hemoglobin and indicates average blood glucose control over roughly the previous two to three months, the lifespan of red blood cells.
Simple analogy
Think of medical nutrition therapy for diabetes like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
