A nurse is caring for a client who has a prescription for one unit of packed RBCs. The nurse should plan to remain in the room with the client at which of the following times during the infusion to observe for a transfusion reaction?

Rationale:A. Observing the final 2 minutes is not sufficient for detecting acute transfusion reactions, which can occur at any time during the transfusion.B. Observing the final 15 minutes is also not adequate; reactions can occur earlier.C. The first 15 minutes is the most critical time for observing for transfusion reactions, as most reactions occur during this period.D. The first 2 minutes are too brief to detect potential transfusion reactions, which typically manifest within the first 15 minutes.
