The nurse is reviewing assessment data for a group of patients. Which patient's findings are consistent with a Type II cytotoxic hypersensitivity reaction?
1. Patient A
2. Patient B
3. Patient C
4. Patient D
Correct Answer: 4
A hemolytic transfusion reaction to blood of an incompatible type is characteristic of a type II or cytotoxic hypersensitivity reaction. IgG or IgM type antibodies are formed to a cell-bound antigen such as the ABO or Rh antigen. When these antibodies bind with the antigen, the complement cascade is activated, resulting in destruction of the target cell. The other patients are not demonstrating signs of a type II hypersensitivity reaction.
