Medical term for suppression of the bone marrow.
Myelosuppression.
Conditions where there is an increase in Hemoglobin.
High altitudes, COPD, smokers, pregnant women.
Why with certain conditions is there an increase in hemoglobin?
The body attempts to provide more oxygen to the cells.
Identify conditions that can cause a decrease in the hemoglobin and the
hematocrit.
Fluid volume overload, Heart Failure, blood loss.
What are the dangers of a low hemoglobin?
Decreased oxygen on the RBC and thus can put an additional strain on the heart
muscle when pumping.

Bleeding.
The patient with a platelet count of 600,000mm3 is at risk for what?
