Which grade indicates a recommendation with substantial certainty of benefit and should be offered?

• A. A
• B. B
• C. C
• D. D

Answer: (A)

USPSTF grades show how confident they are that a preventive service provides net benefit and whether it should be offered. When the net benefit is substantial and the certainty is high, the service receives the top grade and should be offered. That’s why this item points to the highest grade as the correct choice—the one indicating substantial certainty of benefit and a clear recommendation to provide the service. Lower or conditional grades reflect less certainty or a more individualized decision, such as offering only in certain cases, or not recommending it at all, which is why they don’t fit the prompt.
