Which health screening or vaccine is recorded as having occurred in the prescribed time window within N items?

• A. Influenza vaccine in last year
• B. Colonoscopy test in last 5 years
• C. Pneumovax vaccine in last 5 years or after age 65
• D. Hearing exam in last 2 years

Answer: (A)

The main idea is matching each preventive measure to its typical time interval and spotting which one cleanly fits a one-year window. Flu vaccines are given every year, so a record of receiving the influenza vaccine within the last year exactly satisfies a one-year window and is consistently current across most assessments. Colorectal screening like colonoscopy is usually spaced much farther apart (often about 10 years), so a last-five-years window isn’t a universal fit. Pneumovax timing depends on age and risk factors, which introduces conditional timing rather than a fixed annual window. Hearing exams lack a universal cadence and can vary by program or individual, making them less reliably tied to a strict one-year window. In short, the influenza vaccine within the last year best aligns with a fixed, yearly window.
