Which test result should the nurse review to determine the compatibility of blood from two different donors?
- A. Rh factor
- B. ABO typing
- C. Direct Coombs'
- D. Indirect Coombs'
Correct Answer: D
Rationale: The indirect Coombs' test detects circulating antibodies against red blood cells (RBCs) and is the screening component of a prescription to 'type and screen' a client's blood. This test is used in addition to the ABO typing, which is normally done to determine blood type. The Rh factor is determined at the same time as the ABO type. The direct Coombs' test is used to detect idiopathic hemolytic anemia by detecting the presence of autoantibodies against the client's RBCs.
