A nurse is administering a unit of packed RBCS to a client and notes that there are several small clots floating in the IV bag. Which of the following actions should the nurse take?

Nursing care during administration of blood products such as Packed red blood cell transfusion requires strict adherence to safety protocols to prevent transfusion reactions and complications. Blood transfusion is a high-alert procedure because any contamination, abnormal appearance, or incompatibility can lead to life-threatening reactions. Proper inspection of the blood product before administration is a critical nursing responsibility. Any abnormalities must be acted upon immediately according to transfusion safety guidelines. Rationale: A. Injecting heparin into the unit of packed RBCs is inappropriate because blood products must not be mixed with medications unless specifically ordered and compatible. Heparin is an anticoagulant and is not used to treat clots already present in a blood bag. This action could compromise blood safety and increase the risk of adverse transfusion reactions. B. Returning the unit of packed RBCs to the blood bank is the correct action because the presence of clots indicates that the blood product is compromised and unsafe for administration. Clot formation may suggest improper storage, contamination, or product degradation. Administering such blood could lead to embolic complications or transfusion reactions, so it must be rejected and replaced. C. Placing the unit of packed RBCs in a warming unit is incorrect because warming blood does not resolve clot formation or make the product safe for infusion. Blood warmers are only used under specific clinical indications to prevent hypothermia during rapid or large-volume transfusions. This action would not address the safety issue and could worsen product integrity. D. Diluting the unit of packed RBCs with lactated Ringer’s solution is unsafe because blood products should not be mixed with most IV solutions unless explicitly compatible. Lactated Ringer’s contains calcium, which can cause clotting and further compromise the blood product. Additionally, altering the blood unit violates transfusion protocols and increases the risk of adverse reactions.
