When it comes to the maximum amount of time for the transfusion of a unit of packed red blood cells, four hours is the tops. Around 30 minutes is the minimum amount of time. What this four hour maximum rule means is that in order for the blood transfusion to be done correctly and effeciently that the transfusion should be done within four hours of the blood pack being brought out of its cold storage unit.

There have been numerous studies done by medical research companies from all over the world and the consensus is that in order for a unit of packed red blood cells to be able to work properly they need to be transfused within four hours. This makes sure that the blood cells will not coagulate and gell together and the most important thing is that they will be able to be safely transferred and transfused to a needed patient.

According to the rules, the maximum amount of time needed for red blood cells is 4 hours. The answer to this question is letter C. If the pack will be removed for more than 4 hours, then it may not be effective anymore when it is transferred to someone who would need the red blood cells.

There is also another rule that should be followed: the “30-minute rule” states that if the pack has been removed for more than 30 minutes from the controlled storage, it cannot be returned anymore as its quality has already deteriorated at that point. It is important that these rules will be followed to ensure that transfusion will take place correctly and effectively.

4 hours.-rationale: a unit of packed rbcs may be transfused over a period of between 1 and 4 hours. it shouldnt infuse for longer than 4 hours because the risk of contamination and sepsis increases after that time. the nurse should discard any blood not given within this time, or return it to the blood bank, in accordance with facility policy.client needs category: physiological integrityclient needs subcategory: pharmacological and parenteral therapiescognitive level: knowledgereference: taylor, c., et al. fundamentals of nursing: the art and science of nursing care, 6th ed. philadelphia: lippincott williams & wilkins, 2008, p. 1739.
