Question 1 of 5
The main reason a transfusion should be completed in a 4 hour period is that:
Correct Answer: D
Rationale: Blood transfusions must conclude within 4 hours because blood, once removed from refrigeration, risks bacterial growth if left at room temperature too long. Red cells, plasma, and platelets become susceptible to contamination (e.g., from IV lines), potentially causing sepsis. Breakdown of components (e.g., hemolysis) occurs over days, not hours, less urgent than infection risk. Coagulation isn't immediate post-4 hours; it's a slower process unless clotted pre-transfusion. Evaporation isn't plausible blood is sealed in bags. The 4-hour limit, per transfusion standards (e.g., AABB), balances delivery with safety, prioritizing bacterial proliferation prevention, making this the primary reason in nursing practice.
