The nurse suspects that the client is experiencing a reaction to a specific antigen. Which laboratory result supports the conclusion made by the nurse?
A) Indirect Coombs' showing no agglutination
B) Patch test with a 1-inch area of erythema
C) 2% eosinophils in the WBC count
D) Rh antigen with negative results
Answer: B
An area of erythema after a patch test indicates a positive response to a specific antigen. Indirect Coombs' test detects the presence of circulating antibodies against RBCs. No agglutination is considered a normal finding. An eosinophil count of 2% is within the normal range. An Rh antigen with a negative result indicates that the client does not carry the antigen and is not an indicator of a reaction to a specific antigen.
