A nurse is monitoring a client who reports having chills and back pain during a blood transfusion. Which of the following actions is the nurse's priority?

Choice A rationale Notifying the provider is an important subsequent step, but it is not the immediate priority when a client experiences chills and back pain during a blood transfusion. These symptoms are indicative of a potential transfusion reaction, which requires immediate cessation of the transfusion to prevent further complications and potential harm to the client. Choice B rationale Covering the client with a blanket addresses the symptom of chills but does not stop the underlying cause or progression of a potential transfusion reaction. While comfort measures are important, the priority is to halt the administration of the causative agent to prevent further immunological or physiological responses that could escalate to a life-threatening event. Choice C rationale Stopping the transfusion is the immediate priority. Chills and back pain are classic signs of an acute hemolytic transfusion reaction, an immune-mediated response that can rapidly progress to severe complications, including renal failure, disseminated intravascular coagulation, and shock. Prompt cessation minimizes the volume of incompatible blood transfused and limits the severity of the reaction. Choice D rationale Assessing the client's skin for a rash is part of a comprehensive assessment for a transfusion reaction. However, stopping the transfusion takes precedence over this assessment. While a rash can indicate an allergic reaction, chills and back pain are more suggestive of a serious hemolytic reaction, demanding immediate interruption of the blood product.
