What should the nurse do next if the client's oral temperature is 100.0° F before hanging a blood transfusion?

When a client's oral temperature registers at 100.0° F before initiating a blood transfusion, the most appropriate action for the nurse is to call the healthcare provider. This is because a mild fever can indicate a potential reaction to the transfusion, such as a transfusion reaction or other underlying issues that need to be addressed before proceeding.

Identifying and reporting a fever prior to a transfusion is vital, as it prompts further assessment of the client’s condition and ensures their safety. The healthcare provider may need to evaluate whether to proceed with the transfusion or investigate further, such as checking vital signs or considering premedication to mitigate possible reactions. This proactive step ensures that the patient is appropriately monitored and treated, reducing the risk of complications.

Other options like continuing with the transfusion without further assessment could lead to serious adverse events. Documenting the findings alone does not address the immediate clinical implications of a fever. Asking the client how they feel, while it may provide subjective insight into their symptoms, does not replace the necessary evaluation and decision-making that should involve the healthcare provider to ensure safety during the transfusion process.
