In assessing physical activity, what are the two vital sign questions used?

• A. Days per week and type of exercise
• B. Days per week and minutes per day of moderate exercise
• C. Intensity of exercise and duration
• D. Daily steps and active minutes

Answer: (B)

The two vital sign questions used in assessing physical activity generally focus on the frequency and duration of exercise. By asking about the days per week and the minutes per day of moderate exercise, practitioners can gain valuable insights into a person's overall activity level and adherence to recommended guidelines. This approach is effective because it enables health professionals to evaluate whether individuals are meeting the standard physical activity recommendations, which typically suggest engaging in at least 150 minutes of moderate-intensity exercise per week.

Other answer choices involve elements relevant to physical activity assessment but do not directly capture the core frequency and duration metrics. For instance, while understanding the type of exercise and intensity are important, knowing how many days per week and how many minutes per day someone exercises provides a clearer picture of their overall activity level. Similarly, daily steps and active minutes may indicate physical activity but do not directly address the recommended guidelines as effectively as the combination of days and minutes does.
