Clinical context Twelve minutes after a red-blood-cell transfusion begins, a client develops sudden chills, severe low-back pain, chest tightness, hypotension, tachycardia, and dark-red urine, requiring an immediate response for a serious transfusion reaction with hemolysis and shock risk. Review the trend and select the best interpretation and next plan.
Trend
Choose your responses, then check the answer.
Explanation
Blood pressure has improved, but falling urine output, rising creatinine, elevated lactate dehydrogenase, low haptoglobin, and hemoglobinuria show ongoing intravascular hemolysis with kidney-injury risk. Renal perfusion, coagulation, and urine output require continued support and reassessment.
Quick answer Do not mistake partial hemodynamic recovery for resolution of hemolysis and renal risk.
Why this is correct Free hemoglobin, shock, and possible disseminated coagulation can injure the kidneys even after the suspect component has been stopped.
Easy analogy or mental picture Treat every infusion as a controlled clinical system: verify the product and access, recognize a changing cue, stop preventable exposure, stabilize the client, and confirm the response.
NCLEX decision rule Choose the action that prevents the most immediate infusion-related harm while preserving vascular access and the ordered diagnostic evidence.
Why the other choices are wrong Options that restart a suspect product, bypass a safety device, force an occluded tube, or delay reassessment can convert a reversible warning into serious harm.
