What is the expected hematocrit range for a patient with a hemoglobin level of 8.0 g/dL?

To determine the expected hematocrit range for a patient with a hemoglobin level of 8.0 g/dL, it is important to understand the relationship between hemoglobin and hematocrit. Hematocrit is typically about three times the hemoglobin level in healthy individuals. This ratio helps guide estimates of the percentage of blood volume that is occupied by red blood cells.

For a hemoglobin level of 8.0 g/dL, you would expect the hematocrit to be approximately three times that value. Multiplying 8.0 g/dL by 3 gives a hematocrit estimate of about 24%. This serves as a baseline to understand the expected range.

Considering the variability in individual laboratory results and physiological differences, the expected hematocrit would often be reported within a broader range around this estimate, rather than as an exact figure. The range from 21% to 27% accommodates these variations, thus making it a reasonable expectation for a patient with a hemoglobin level of 8.0 g/dL.

The other options provide narrower ranges or do not align with the expected calculations, which makes them less applicable given the typical hemoglobin to hematocrit correlation. The selected range effectively captures the anticipated
