In the ED, blood is withdrawn from the vein and into a test tube. The packed cell volume (RBCs) is 1.45 ml, and the plasma volume is 3.55 ml. Calculate Maggie's hematocrit in the ED. CHEGG

Explanation:

HCT is calculated as:

HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100  

1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT  ranges from 38 to 46% (some sources claim 34.9-44.5%).

*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.

Total blood volume = Packed cell volume + plasma volume.

the answer is b. glad to .

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
