During platelet administration, which action should a nurse take first if a client reports lower back pain and feeling chilled and itchy?

When a client reports symptoms such as lower back pain, feeling chilled, and itchiness during platelet administration, the most immediate and appropriate action is to stop the infusion. This is because these symptoms are often indicative of a transfusion reaction, which can range from mild to severe and potentially life-threatening. Stopping the infusion halts the introduction of any further transfusion-related substances into the bloodstream, minimizing the risk of harm.

Immediately ceasing the infusion allows for the assessment and management of the client’s symptoms, as well as safeguarding their wellbeing. It also provides time to initiate any necessary medical interventions according to institutional protocols.

Following this action, it would be appropriate to notify the healthcare provider and take other necessary steps, such as collecting a urine sample or returning the blood product for further investigation, but the priority is ensuring the transfusion does not continue. Promptly stopping the infusion is essential in a situation like this, where transfusion reactions can escalate rapidly.
