Q

if you had a high hematocrit, would you expect your hemoglobin determination to be high or low? Why?

A

high; increase hematocrit, increase RBC count, and high hemoglobin

Q

what blood type is theoretically considered the universal donor? Why?

27
Q

a permanent move from sea level to high-altitude area
