Which laboratory test will the nurse use to determine whether filgrastim (Neupogen) is effective for a patient with acute lymphocytic leukemia who is receiving chemotherapy?
Reticulocyte count
White blood count / Absolute neutrophil count
Total lymphocyte count
Platelet count
The Correct Answer is B
A. Reticulocyte count: Reticulocyte count measures immature red blood cells and is not the primary measure for the effectiveness of filgrastim, which is used to boost white blood cells.
B. White blood count / Absolute neutrophil count: Filgrastim (Neupogen) is used to increase white blood cells, specifically neutrophils. Therefore, monitoring the white blood count (WBC) and absolute neutrophil count (ANC) is the appropriate way to determine the effectiveness of the drug.
C. Total lymphocyte count: While lymphocytes are a type of white blood cell, filgrastim primarily affects neutrophils, making WBC/ANC a better indicator.
D. Platelet count: Filgrastim does not directly impact platelet production, so platelet count is not the primary measure of its effectiveness.
