Question 3 of 5

After receiving five doses of filgrastim, the nurse notes that the client's white blood cell count has increased from 2,500/mm3 (2.5 x 109/L) to 5,000/mm3 (5 x 109/L). Which action should the nurse implement?

Correct Answer: B

Rationale: Filgrastim stimulates white blood cell production. An increase to 5,000/mm3 (
B) indicates effectiveness (matches 55-Q11). Neutropenic precautions (

Topical antibiotics (
