What is the priority action for a nurse when a client vomits bright red blood after eating?

The priority action for a nurse when a client vomits bright red blood after eating revolves around the critical assessment of the situation, as the presence of fresh blood in vomit indicates potential upper gastrointestinal bleeding. Drawing blood for typing and crossmatching is vital because it prepares for the possibility of a blood transfusion if the client requires it due to significant blood loss. The immediate collection of this blood type information allows for rapid response in case the physician orders a transfusion, which is a common intervention in cases of substantial bleeding to restore blood volume and prevent shock.

While notifying the physician is important, the timing of blood typing and crossmatching provides the necessary information to act swiftly if blood products are needed. Monitoring vital signs closely is crucial as well, as it helps to assess the client's hemodynamic status; however, it doesn't directly address the urgent need for typing and crossmatching that may be necessary for treatment. Providing IV fluids is also a supportive measure but does not replace the need for blood products in the event of significant blood loss. In summary, promptly drawing blood for typing and crossmatching is a critical step to prepare for any interventions that might arise due to the client's condition.
