Question 1 of 5
The client who received 50 mL from a unit of whole blood has low back pain. In response to this client’s symptom, which action should be taken by the nurse first?
Correct Answer: D
Rationale: A. Repositioning focuses on treating the client’s back pain and not on the blood transfusion, which could be the cause of the back pain. B. Further assessment should occur after stopping the blood transfusion. C. The client may need an analgesic for pain control, but this should occur after stopping the blood transfusion. D. Low back pain is a symptom of a potentially life-threatening acute hemolytic reaction. The pain is caused from agglutination of RBCs in the kidneys and renal vasoconstriction. Hemolytic reactions occur most often within the first 50 mL of the infusion.
Question 2 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.
