Fever, chills, flank/back pain, hypotension, or dark urine → stop immediately (hemolytic reaction).
Before you read
Test yourself first: 5 questions
Question 1 of 5
A nurse is starting a blood transfusion. Which initial action is most important for patient safety?
Answer: B. Two qualified staff must verify the blood product against the order and the patient's identity at the bedside before starting, because a clerical mismatch is the leading cause of fatal hemolytic transfusion reactions. Blood is administered with normal saline only, and the nurse stays for the first 15 minutes; verification comes first.
Question 2 of 5
During a transfusion, a client develops hives, itching, and flushing but no fever or respiratory distress. After stopping the infusion, which intervention does the nurse anticipate for this mild allergic reaction?
Answer: A. Urticaria, itching, and flushing without other systemic signs indicate a mild allergic (urticarial) reaction. The transfusion is stopped, and an antihistamine such as diphenhydramine is given. If symptoms resolve, the transfusion may sometimes be cautiously resumed per protocol.
Question 3 of 5
During a blood transfusion the client develops fever, chills, and back pain. What does the nurse do FIRST?
Answer: B. Stop the transfusion immediately (this could be an acute hemolytic reaction), keep the line open with normal saline via new tubing, and notify the provider/blood bank.
Question 4 of 5
Which finding in a client receiving a blood transfusion most strongly suggests an acute hemolytic reaction?
Answer: B. Fever, chills, low back/flank pain, dark urine, and hypotension shortly after starting blood suggest acute hemolytic reaction (ABO incompatibility) — STOP the transfusion immediately and keep the line open with saline.
Question 5 of 5
Fifteen minutes into a blood transfusion the client reports chills, back pain, and feels feverish. The nurse's FIRST action is:
Answer: B. Stop the transfusion immediately and keep the line open with normal saline via new tubing — a possible hemolytic reaction. Then notify the provider and blood bank.
Keep the streak going with more questions like these, each with a full rationale.
What is blood transfusion safety?
Two-person verification, a dedicated saline line and close early monitoring are the safety backbone. Before the transfusion, consent, a current type and crossmatch, a working IV (20-gauge or larger in adults) and baseline vital signs are confirmed; during it, the first 15 minutes carry the highest risk of an acute hemolytic reaction, so the nurse stays at the bedside and starts slowly.
Key points to remember
- Two RNs verify ID, type, unit #
- Large-bore IV, NS only
- Baseline vitals
- Stay first 15 min, slow start
- Finish within 4 hours
- Fever, chills, flank pain, dark urine
- Stop, keep line open w/ NS, notify
- Verify the order, consent, the patient's identity with two identifiers, ABO/Rh compatibility and the unit number with a second qualified person at the bedside.
- Use a blood administration set with a filter, and prime and flush with 0.9% sodium chloride only.
- Start within 30 minutes of picking the unit up from the blood bank, and finish each unit within 4 hours.
- Take vital signs before, 15 minutes after the start, per policy during, and after the transfusion.
- Reaction types: acute hemolytic (fever, chills, flank pain, low blood pressure, dark urine), febrile (fever, chills), allergic (hives, itching; anaphylaxis if severe), circulatory overload (shortness of breath, crackles, high blood pressure), and sepsis from a contaminated unit (high fever, shock).
Nursing priorities
- If a reaction occurs, STOP the transfusion first, then keep the line open with normal saline and notify the provider/blood bank.
- Only 0.9% normal saline may run with blood.
- For any reaction: stop the transfusion, disconnect the blood tubing, keep the vein open with saline through new tubing, stay with the patient, notify the provider and blood bank, and return the bag and tubing.
- Watch older adults and patients with heart failure for fluid overload; a slower rate or a diuretic may be ordered.
Labs & values
Patient teaching
- Two RNs verify patient ID, blood type, and unit number at the bedside before starting.
- Start slowly and stay with the patient for the first 15 minutes; complete each unit within 4 hours.
- Tell the nurse right away about chills, itching, back pain, trouble breathing or feeling unwell during the transfusion.
Red flags: report now
- Fever, chills, flank/back pain, hypotension, or dark urine → stop immediately (hemolytic reaction).
- Never infuse blood with dextrose or LR — it hemolyzes/clots the cells.
- Shortness of breath, crackles, rising blood pressure and distended neck veins during a transfusion suggest circulatory overload — stop or slow the infusion, sit the patient up and notify the provider.
