Question

Answer 1

A unit of red cells removed from a blood fridge for transfusion must be used within 4 hours to ensure safety and viability.

Step-by-step explanation:

When a unit of red cells is removed from a blood fridge for transfusion to an adult patient, it is important to remember that the transfusion must be completed within a set time frame to ensure the safety and viability of the blood product. For a unit of blood, this time frame is 4 hours, as red blood cells (erythrocytes) have a limited lifespan once out of storage and the risk of bacterial contamination increases the longer the blood is at room temperature. Considering both the patient's well-being and the integrity of the blood transfusion process, it is crucial to complete the transfusion within the 4-hour window.
