Question 13

Hemoglobin (anemia vs dehydration)

Answer 13

Decreased HGB = decreased RBC or anemia

Increased HGB = increased RBC production or decreased volume (dehydration)

Question 14

Hematocrit

Answer 14

Measures % of RBCs in blood
Increased HCT = increased marrow production
Decreased HCT = blood loss or increased RBC destruction

Answer 17

Dehydration
Exogenous testosterone or hormone use
Hypoxia
Respiratory dx
Smoking
Polycythemia Vera
Spleen hypofxn

Answer 23

Mean capsular volume
Measures volume or size of RBC

Indicates: cell is normal, microcytic or macrocytic

May be normal with folic acid or iron deficiency anemia
