Blood Product Transfusion Monitoring - NCLEX Pn
- Which vital sign schedule is standard during initiation of a blood transfusion?
- Baseline, 15 min after start, then per policy (often hourly), and at end. Allows early detection of reactions, as most occur soon after initiation, with ongoing monitoring for changes.
- What is the hallmark nursing finding that suggests circulatory overload during transfusion (TACO)?
- Dyspnea with hypertension and crackles (fluid overload). Indicates pulmonary edema from excessive volume overwhelming cardiac capacity in at-risk patients.
- Identify the classic early signs of an acute hemolytic transfusion reaction.
- Fever/chills, flank/back pain, hypotension, hemoglobinuria. These symptoms result from ABO incompatibility causing rapid red cell destruction and systemic response.
- Which documentation is essential during blood transfusion monitoring?
- Start/stop times, product ID, rate, vital signs, and patient response. Provides legal record of procedure adherence and early detection of adverse events for quality care.
- What is the maximum time blood may remain at room temperature before transfusion should begin?
- Begin within 30 minutes of receiving the unit (per common policy). Prevents bacterial growth by limiting exposure time outside controlled refrigeration.
- Which symptom indicates anaphylaxis during transfusion and requires emergency response?
- Wheezing/stridor with hypotension. Represents severe allergic response with airway compromise and shock, necessitating immediate epinephrine and support.
- What finding most strongly suggests TRALI rather than TACO during transfusion monitoring?
- Acute hypoxemia with hypotension and noncardiogenic pulmonary edema. TRALI involves immune-mediated lung injury without cardiac involvement, differing from TACO's volume-related hypertension.
- Which IV solution is compatible with packed red blood cells for transfusion monitoring?
- 0.9% normal saline only. Isotonic saline prevents hemolysis or clotting, unlike other solutions that may damage red cells.
- Which patient statement during transfusion requires stopping the infusion: "I feel back pain" or "I am tired"?
- "I feel back pain." Back pain signals possible hemolytic reaction from kidney involvement, unlike fatigue which may be nonspecific.
- Which blood product is most associated with allergic reactions such as urticaria and pruritus?
- Plasma-containing products (especially platelets or plasma). These products contain donor proteins that can trigger IgE-mediated hypersensitivity in recipients.
- What is the correct action for the IV line after stopping a suspected transfusion reaction?
- Keep IV open with 0.9% normal saline using new tubing. Maintains venous access for emergency interventions while avoiding further blood infusion and contamination.
- Which IV gauge is typically preferred for adult packed red blood cell transfusion?
- Large-bore IV, typically 18–20 gauge. Facilitates adequate flow rate without causing red cell hemolysis from excessive pressure in smaller gauges.
- After stopping a transfusion reaction, what should be done with the blood bag and tubing?
- Send blood bag and tubing to the blood bank per protocol. Allows laboratory analysis to identify reaction cause and prevent future errors.
- What specimen is commonly obtained after a suspected hemolytic transfusion reaction?
- Blood and urine samples for hemolysis workup per protocol. Detects free hemoglobin and other markers confirming intravascular hemolysis from incompatibility.
- What is the key difference between febrile nonhemolytic reaction and acute hemolytic reaction?
- Febrile: fever/chills only; hemolytic: hypotension, back pain, hemoglobinuria. Febrile reactions are benign cytokine-mediated, while hemolytic involves destructive antibody response with systemic effects.
- What bedside check must be completed immediately before starting a blood transfusion?
- Two-identifier patient match to blood product label and compatibility. Ensures prevention of clerical errors, the most common cause of hemolytic reactions, through dual verification.
- What is the priority nursing action when a transfusion reaction is suspected?
- Stop the transfusion immediately. Prevents further antigen exposure and potential worsening of the reaction, prioritizing patient safety.
- Which assessment finding during transfusion most strongly suggests sepsis from contaminated blood?
- High fever with rigors and hypotension during transfusion. Indicates bacterial endotoxin release causing septic shock, a rare but life-threatening complication.
- What is the correct tubing requirement when administering blood products?
- Use blood administration set with in-line filter. Filters remove microaggregates and debris, reducing risk of reactions while ensuring safe administration.
- What is the appropriate action for mild urticaria during transfusion when no respiratory symptoms occur?
- Stop temporarily; give antihistamine per order; restart if symptoms resolve. Mild allergic reactions can often be managed without permanent discontinuation if symptoms abate after treatment.
- What is the most critical monitoring period for acute transfusion reactions?
- The first 15 minutes of the transfusion. Most acute reactions manifest early due to rapid antigen-antibody interactions upon blood introduction.
- What is the maximum time a unit of packed red blood cells should hang once started?
- Complete within 4 hours. Minimizes bacterial proliferation risk in blood at room temperature, adhering to safety standards.
- Which intervention is expected for suspected TACO during a transfusion?
- Stop transfusion, place upright, administer oxygen and diuretic as ordered. Reduces fluid overload effects by stopping infusion, improving breathing, and promoting diuresis as needed.
- Identify the correct immediate action if the patient develops new dyspnea and crackles mid-transfusion.
- Stop transfusion and assess for TACO/TRALI; apply oxygen. Addresses potential pulmonary complications like overload or injury by halting cause and supporting oxygenation.
- Which patient report during transfusion requires immediate action: itching, chills, or mild hunger?
- Chills. Chills may indicate a febrile or hemolytic reaction requiring prompt intervention, unlike mild hunger which is unrelated.
