In a physical assessment, which measurement is typically used to assess body mass?

• A. Height
• B. Waist circumference
• C. Temperature
• D. Weight

Answer: (D)

Measuring body mass is about how much matter is in the body, and the most direct measure is weight. Height indicates how tall someone is and is used with weight to estimate BMI, but it doesn't measure mass itself. Waist circumference gauges abdominal fat distribution, not total body mass. Temperature is a vital sign reflecting the body's heat and is unrelated to mass. In a physical assessment, a scale provides weight in kilograms or pounds, which is the body’s mass. If BMI is needed, you combine that weight with height, but the actual mass measurement remains weight.
