What should a healthcare provider do if a transfusion reaction is suspected?

When a transfusion reaction is suspected, stopping the transfusion immediately is crucial because it minimizes the risk of further complications and allows for a timely assessment and management of the patient's condition. This action is fundamental in ensuring patient safety, as continuing the transfusion could worsen the reaction and lead to severe adverse outcomes.

Notifying the physician right away is also essential because they can provide further instructions based on the patient's clinical presentation and the type of reaction suspected. This facilitates prompt medical intervention, which could include supportive care and additional testing.

Other options, such as continuing the transfusion while monitoring the patient or giving additional fluids, could aggravate the situation and delay appropriate treatment. Documenting the reaction is important, but it should come after immediate interventions have been taken to safeguard the patient's health. Thus, stopping the transfusion and notifying the physician represent the correct initial response in handling a suspected transfusion reaction.
