Key Takeaways
- Blood products must be verified by two licensed nurses at the bedside: check patient ID, blood type, Rh factor, expiration, and unit number
- Only 0.9% Normal Saline is compatible with blood products - never use dextrose solutions or LR
- Blood must be transfused within 4 hours of leaving blood bank to prevent bacterial growth
- Acute hemolytic reaction presents with fever, chills, flank pain, and hemoglobinuria - stop transfusion immediately
- Use an 18-20 gauge catheter for blood transfusion; smaller gauges cause hemolysis
Blood Product Administration
Blood transfusion is a potentially life-saving intervention that carries significant risks. The NCLEX heavily tests your knowledge of safe transfusion practices and recognition of transfusion reactions.
Blood Products
| Product | Contains | Indications |
|---|---|---|
| Packed Red Blood Cells (PRBCs) | RBCs with minimal plasma | Anemia, blood loss |
| Fresh Frozen Plasma (FFP) | Clotting factors | Coagulopathy, warfarin reversal |
| Platelets | Platelet concentrate | Thrombocytopenia, bleeding |
| Cryoprecipitate | Fibrinogen, Factor VIII | DIC, hemophilia A |
| Whole Blood | All components | Massive hemorrhage (rare) |
| Albumin | Plasma protein | Volume expansion, hypoalbuminemia |
Pre-Transfusion Requirements
Before Blood Leaves Blood Bank:
- Order verified
- Type and crossmatch completed
- Patient consent obtained
- Baseline vital signs documented
- Patent IV access confirmed (18-20 gauge)
The Two-Person Verification
Both nurses at the bedside verify:
| Verification Point | What to Check |
|---|---|
| Patient identification | Name and DOB (ask patient to state) |
| Armband matches | Blood bank slip matches armband |
| Blood type | ABO and Rh compatible |
| Unit number | Blood bag matches slip |
| Expiration date | Product not expired |
| Visual inspection | No clots, discoloration, or leaks |
Both nurses sign documentation before transfusion begins.
Blood Type Compatibility
ABO Compatibility:
| Patient Blood Type | Can Receive |
|---|---|
| Type O | O only (Universal donor for RBCs) |
| Type A | A, O |
| Type B | B, O |
| Type AB | A, B, AB, O (Universal recipient) |
Rh Compatibility:
- Rh negative patients should receive Rh negative blood
- Rh positive patients can receive either
Administration Protocol
Equipment:
- Blood administration set with in-line filter
- IV pump (if approved for blood)
- 0.9% Normal Saline (only compatible solution)
- 18-20 gauge IV catheter (larger for rapid transfusion)
Procedure:
- Prime tubing with Normal Saline
- Start transfusion slowly: 2 mL/min for first 15 minutes
- Stay with patient for first 15 minutes
- Take vital signs: baseline, 15 min, 30 min, end of transfusion
- Complete transfusion within 4 hours of leaving blood bank
- Document per facility policy
Rate Guidelines:
- PRBCs: Usually over 2-4 hours
- Platelets: Usually over 15-30 minutes
- FFP: Usually over 30 minutes to 2 hours
- Adjust based on patient tolerance
Transfusion Reactions
Acute Hemolytic Reaction (Most Severe)
Cause: ABO incompatibility - immune destruction of transfused cells
Onset: Within minutes to hours
| Signs/Symptoms | Pathophysiology |
|---|---|
| Fever, chills | Immune response |
| Flank/back pain | RBC destruction in kidneys |
| Chest pain, dyspnea | Intravascular hemolysis |
| Hypotension | Shock response |
| Hemoglobinuria | Free hemoglobin in urine |
| DIC | Coagulation cascade activated |
Intervention:
- STOP transfusion immediately
- Keep IV line open with NEW tubing and saline
- Stay with patient
- Notify provider and blood bank STAT
- Send blood bag and tubing to lab
- Draw blood samples as ordered
- Monitor urine output (renal failure risk)
- Prepare for emergency intervention
Febrile Non-Hemolytic Reaction (Most Common)
Cause: Antibodies against donor WBCs
Signs: Temperature rise > 1°C (1.8°F), chills, mild dyspnea
Intervention:
- Stop transfusion
- Notify provider
- Rule out hemolytic reaction
- Antipyretics as ordered
- May be able to resume with leukocyte-reduced blood
Allergic Reaction
Cause: Sensitivity to donor plasma proteins
Mild Signs: Urticaria (hives), itching, flushing
Intervention for Mild Reaction:
- Stop transfusion temporarily
- Notify provider
- Administer antihistamine (diphenhydramine) as ordered
- May resume if symptoms resolve
Anaphylactic Reaction (Severe):
- Bronchospasm, stridor
- Angioedema
- Hypotension, shock
Intervention:
- Stop transfusion permanently
- Maintain airway
- Epinephrine as ordered
- Full resuscitation if needed
Transfusion-Related Acute Lung Injury (TRALI)
Cause: Donor antibodies attack recipient lung tissue
Signs: Within 6 hours of transfusion
- Acute respiratory distress
- Pulmonary edema (non-cardiogenic)
- Hypoxia
- Fever
Intervention:
- Stop transfusion
- Supportive respiratory care
- May require mechanical ventilation
Circulatory Overload (TACO)
Risk Factors: Elderly, heart failure, renal failure
Signs:
- Dyspnea, orthopnea
- Jugular vein distension
- Crackles in lungs
- Hypertension
Prevention: Slow infusion rate, may give furosemide between units
Quick Response Guide
| If You Observe | Action |
|---|---|
| Any reaction signs | STOP transfusion |
| Fever, chills | Rule out hemolytic reaction |
| Hives only | May continue after antihistamine |
| Respiratory distress | Stop permanently, call RRT |
| Flank pain, hemoglobinuria | Emergency - hemolytic reaction |
Documentation Requirements
- Consent obtained
- Pre-transfusion vital signs
- Two-nurse verification (both signatures)
- Time transfusion started
- Vital signs at 15 min, 30 min, end
- Volume transfused
- Any reactions and interventions
- Post-transfusion assessment
On the Exam
- Know the verification process
- Only Normal Saline with blood
- Complete within 4 hours
- Recognize hemolytic reaction signs
- First action for any reaction: STOP the transfusion
During a blood transfusion, the patient develops fever, chills, low back pain, and reports blood-tinged urine. The nurse should FIRST:
Which IV solution is compatible with blood product administration?
A unit of PRBCs has been out of the blood bank refrigerator for 4.5 hours and is only half infused. The nurse should:
A patient with blood type AB positive can safely receive which of the following blood products?
