Place the nursing actions in order after a client receiving a red-blood-cell transfusion develops acute dyspnea, crackles, and an oxygen saturation of 86%.

Quick answer
Stop the transfusion, then apply oxygen and elevate the head of the bed, then notify the provider, then obtain vital signs and a chest X-ray order, then return the blood product to the blood bank.

Why this is correct
The priority is to stop the infusion causing the overload. Oxygen and positioning address hypoxemia. The provider must be notified to direct further treatment. Vital signs and diagnostic tests help confirm TACO. The blood product is returned after the client is stabilized and the reaction is documented.

Clinical picture
TACO is a transfusion reaction characterized by acute respiratory distress, crackles, hypertension, and hypoxemia due to volume overload. Immediate management includes stopping the transfusion, sitting the client upright, administering oxygen, and notifying the provider. Diuretics may be ordered. The blood product and tubing are sent to the blood bank for investigation.

Memory hook
In any transfusion reaction, the first step is always to stop the transfusion. Then assess and support ABCs, notify the provider, and preserve the product for investigation.

NCLEX decision rule
Prioritize airway, breathing, and circulation. Stop the source of the problem before further assessment or intervention.

Why the alternatives are wrong
Applying oxygen before stopping the transfusion would allow continued fluid administration and worsen overload. Notifying the provider before stopping the transfusion delays critical intervention. Returning the blood product before stabilizing the client is unsafe.
