Which divisor is correct for the mass-based blood volume calculation?

• A. Mass divided by 0.015
• B. Mass divided by 0.025
• C. Mass divided by 0.02
• D. Mass divided by 0.01

Answer: (A)

The calculation relies on a fixed conversion factor that turns body mass into blood volume. In this setup, dividing by 0.015 is the correct way to apply that factor, because 0.015 is the specific constant the problem uses to convert mass into the desired volume units. Using this divisor yields a result that fits the expected range and units for blood volume in the given context. The other divisors correspond to different conversion factors and would produce volumes that don’t align with the problem’s specified units or the typical ranges used in these calculations. So dividing by 0.015 is the correct approach.
