해설
Patient safety is the highest priority in blood transfusion administration. Proper patient identification and blood compatibility verification prevent potentially fatal transfusion reactions.
Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing intervention before administering a blood transfusion, specifically for a pediatric patient with β-thalassemia major. This condition requires lifelong, regular transfusions to manage severe anemia. The core principle is patient safety, with the prevention of Key Point!acute hemolytic transfusion reactions being the most critical concern. These reactions, often due to ABO incompatibility, can be life-threatening and are primarily prevented by meticulous verification procedures.
Answer Rationale: The correct answer is ① Verify the child's identity and blood compatibility using two patient identifiers and cross-check with another qualified nurse. This is the Key Point!universal and non-negotiable first step in any blood transfusion protocol. It directly addresses the greatest risk. Using two unique patient identifiers (e.g., name and medical record number) and a double-check by another qualified nurse is the standard of care mandated by organizations like The Joint Commission to prevent clerical errors that could lead to administering incompatible blood.
Distractor Analysis:
Watch out for confusion!② Administer premedication with acetaminophen to prevent transfusion reactions: Premedication (often with acetaminophen and/or diphenhydramine) is sometimes used to prevent febrile or allergic reactions, but it is not a universal requirement nor the priority. It is typically ordered for patients with a history of such reactions. More importantly, premedication does not prevent the most dangerous acute hemolytic reaction, which is why verification comes first.
Watch out for confusion!③ Ensure the child has voided within the past hour to monitor for hemoglobinuria: Monitoring urine output and color (for hemoglobinuria) is an important assessment during and after the transfusion to detect signs of a hemolytic reaction. However, ensuring voiding before the transfusion is not a standard priority intervention. The focus before starting is on prevention through verification.
Watch out for confusion!④ Start the transfusion at a rapid rate to minimize the time the blood is outside refrigeration: This is incorrect and dangerous. Blood transfusions, especially in pediatric patients, must be started slowly (e.g., 2 mL/kg/hr for the first 15 minutes) while closely monitoring for any adverse reaction. A rapid start could overwhelm the patient if a reaction occurs. While blood should not be left at room temperature indefinitely, a slow, monitored start is the safe standard.
Related Concepts: For patients with thalassemia on chronic transfusion therapy, long-term complications like iron overload and alloimmunization (developing antibodies to donor blood) are major concerns. Nursing care also includes monitoring for signs of transfusion reactions, assessing for effectiveness (reduced fatigue, improved activity tolerance), and educating the family about the need for iron chelation therapy.

Side-by-Side Comparison!
Intervention
Timing (Priority Order)
Purpose/Rationale
1. Verify ID & Compatibility
First / Before anything else
Prevents life-threatening hemolytic reactions. Absolute priority for safety.
2. Obtain Baseline Vital Signs
Second / Before initiation
Provides comparison data to identify reactions during transfusion.
3. Administer Premeds (if ordered)
Third / Before initiation
May reduce fever/allergy symptoms; does not prevent hemolytic reactions.
4. Start Transfusion SLOWLY
Fourth / Initiation phase
Allows for early detection of a reaction before a large volume is infused.
5. Monitor for Reactions
Ongoing / During & after
Early recognition and intervention for any adverse event.
Anatomy, Physiology & Pharmacology Points
Pathophysiology of Thalassemia: Deficiency in β-globin chain synthesis leads to ineffective erythropoiesis, hemolysis, and severe anemia (low Hgb). Transfusions provide healthy RBCs to improve oxygen-carrying capacity.
Transfusion Reaction Mechanism: ABO incompatibility causes donor RBCs to be attacked by the recipient's antibodies (IgM), leading to intravascular hemolysis, hemoglobin release, and potential for acute kidney injury.
Premedication: Acetaminophen is an antipyretic/analgesic. Diphenhydramine is an antihistamine. They manage symptoms of febrile non-hemolytic or mild allergic reactions but do not treat or prevent hemolytic reactions.
Memory Tips
ABCs of Transfusion: Always Be Certain → Always verify with a Buddy (another nurse) and Check the ID/compatibility.
Priority Order Mnemonic: "Verify Before You Pour" → Verify ID, Baseline VS, Your premeds (if ordered), then Pour slowly.
High-Frequency NCLEX Topics
The NCLEX heavily tests safety and priority-setting. Blood administration is a classic topic. Remember: Assessment and verification for safety always come before implementation of a procedure. You will also be tested on recognizing signs of different transfusion reactions (hemolytic vs. febrile vs. allergic).
Watch Out for Question Variations!
Instead of "priority before," the question could ask: "Which action by the nurse requires immediate intervention?" The correct answer would be a nurse failing to verify ID or starting the transfusion too fast.
The scenario could shift to a patient during a transfusion showing symptoms (e.g., chills, low back pain). The priority then becomes: STOP the transfusion, keep the IV line open with normal saline, notify the physician, and monitor vital signs.
Nursing Clinical Practice GuideClinical Scenario: You are preparing to administer a unit of packed red blood cells (PRBCs) to Liam, a 6-year-old with β-thalassemia major who is in the pediatric outpatient infusion center for his monthly transfusion. His mother is present. He has an IV saline lock in his left hand.
Nursing Intervention Strategy:
Assessment & Preparation:
Review the physician's order and transfusion consent.
Assess the IV site for patency and signs of inflammation.
Safety Verification (The Critical Step):
With another RN/LPN, go to the patient's bedside.
Ask the child (and confirm with the parent) to state his full name and date of birth. Do not ask "Are you Liam?" (leading question).
Compare this information with his ID band and the blood product tag.
Together, verify the:
Patient's name and medical record number on the ID band match the blood product tag and the requisition form.
Blood group (ABO) and Rh type on the product match the patient's confirmed type.
Unit number on the blood bag.
Expiration date and time.
Both nurses sign the verification form.
Implementation:
Administer ordered premedications (if any) and allow time for them to take effect.
Prime the blood administration set with 0.9% Normal Saline (NS).
Start the transfusion SLOWLY. For a child, this often means using a syringe pump or volume-controlled set. A common order is to infuse the first 50 mL (or 2 mL/kg) over the first 15-30 minutes while remaining at the bedside.
Re-assess vital signs 15 minutes after starting.
If no reaction, you may increase the rate to complete the transfusion within the ordered time (usually 2-4 hours for PRBCs).
Monitoring & Evaluation:
Stay with the patient for the first 15 minutes.
Monitor for any signs of reaction: fever, chills, rash, itching, respiratory distress, back pain, anxiety.
Take vital signs per protocol (e.g., every 15 min x 2, then every hour until 1 hour post-transfusion).
Document everything: verification, start time, vital signs, patient tolerance, completion time, and any interventions.
Patient Safety and Precautions:
Never add medications to a blood product.
Use only 0.9% NS to prime the line or flush. Other solutions (like Lactated Ringer's or solutions containing dextrose) can cause hemolysis.
Blood must be infused within 4 hours of leaving controlled refrigeration to prevent bacterial growth.
For chronic transfusion patients, be aware of the signs of transfusion-associated circulatory overload (TACO)—cough, dyspnea, crackles—and transfusion-related acute lung injury (TRALI).
Use a Y-type blood administration set with filter.
Filter traps clots and aggregates.
3. Priming
Prime with 0.9% Normal Saline only.
Prevents hemolysis of RBCs.
4. Start Rate
2 mL/kg/hr for first 15-30 min (pediatric).
Example: 20 kg child → 40 mL/hr initial rate.
5. Maintenance Rate
Calculate to complete within 4 hours.
Rate (mL/hr) = Volume (mL) / Time (hr). Monitor for TACO.
6. Post-Transfusion
Flush line with 0.9% NS. Monitor for delayed reactions.
Document completion and patient response.
A Word from Your Senior Nurse
"In the hustle of a busy unit, it can be tempting to skip the 'annoying' double-check or to hurry a transfusion along. Don't. That verification process is your patient's lifeline. I've seen near-misses caught because two nurses took that extra 60 seconds. For our thalassemia kids who will have hundreds of transfusions in their lifetime, building a routine of impeccable safety from the start is part of our trust contract with them and their families. On the NCLEX, they are testing if you have this safety mindset hardwired. It's not just a test answer—it's the foundation of safe nursing practice."
