Final answer:
The acceptable hematocrit range for blood donation is typically 37-47 percent for females and 42-52 percent for males, corresponding to normal hematocrit values. For a hematocrit of 42 percent, 58 percent of the blood would be plasma.
Step-by-step explanation:
The acceptable hematocrit range for blood donation generally falls within the normal hematocrit values, which for females range from 37 to 47 percent, with a mean value of 41 percent; for males, hematocrit ranges from 42 to 52 percent, with a mean of 47 percent. For blood donation, exact acceptable values can vary slightly between different donation centers and organizations, but they typically require that a donor's hematocrit be within these normal ranges to ensure the safety and effectiveness of the blood donation process.
Moreover, answering critical thinking question number 27, if a patient's hematocrit is 42 percent, approximately 58 percent of the patient's blood is plasma (100 percent minus 42 percent).
