  B)

Answer to Question 1

Ans:
A

Feedback:

The CSFs that act on committed progenitor cells include erythropoietin (EPO), which stimulates RBC production. TPO stimulates platelets. Neupogen is for white blood cell production. Interleukin is a cytokine utilized as an immune response agent.

Answer to Question 2

Ans:
A

Feedback:

Increases in erythropoietin production are associated with secondary polycythemia, and not polycythemia vera, a health problem that can be induced by the hypoxia resulting from smoking and lung disease. Dehydration is associated with relative polycythemia, and sudden blood loss would not manifest in increased erythropoietin production.
