Question 1 of 5
The client diagnosed with leukemia has received a bone marrow transplant. The nurse monitors the client’s absolute neutrophil count (ANC). What is the client’s neutrophil count if the WBCs are 2.2 (x103/mm3), neutrophils are 25%, and bands are 5%?
Correct Answer: 660
Rationale: ANC = WBC × (neutrophils% + bands%). WBC = 2,200/mm3, neutrophils = 25%, bands = 5%. ANC = 2,200 × (0.25 + 0.05) = 2,200 × 0.3 = 660/mm3.
