A nurse is monitoring a client who is receiving packed RBCs. The nurse identifies which of the following as an expected finding?
A The drip chamber with filter is filled completely with blood.
B The blood has been infusing steadily for 5 hr with no client symptoms.
C A medication is being administered IV through the injection site closest to the client.
D The packed RBCs are connected by Y tubing to normal saline.
The Correct Answer and Explanation is :
The correct answer is:
D. The packed RBCs are connected by Y tubing to normal saline.
Explanation:
When administering packed red blood cells (RBCs), it is essential to follow proper procedures to ensure the safety and effectiveness of the transfusion. The connection of packed RBCs to normal saline using Y tubing is a standard practice for several reasons:
- Normal Saline as a Diluent: Normal saline (0.9% sodium chloride) is used in conjunction with packed RBCs to maintain venous access and to help prevent hemolysis. Saline serves as a diluent that facilitates the smooth flow of blood through the intravenous (IV) tubing, reducing the risk of clot formation and ensuring the transfusion proceeds without interruption.
- Preventing Blood Clotting: The Y tubing setup allows the blood to be administered through one arm of the Y while normal saline is infused through the other. This helps to keep the blood flowing and prevents clotting in the IV line, which can occur if blood is left to sit in the tubing without continuous infusion.
- Minimizing Complications: Using Y tubing and normal saline helps to minimize complications such as hemolysis or reactions that can occur if blood is mixed with other medications or solutions. Saline ensures that the packed RBCs are delivered effectively and safely.
- Following Protocols: This practice aligns with standard transfusion protocols and guidelines, which recommend using normal saline to flush the IV line before and after the transfusion and to keep the blood from clotting in the tubing.
In contrast:
- A: The drip chamber should not be completely filled with blood; it should be partially filled to allow for proper monitoring of the blood flow.
- B: The transfusion time should not exceed 4 hours to reduce the risk of bacterial growth and other complications.
- C: No medications should be administered through the same IV line used for blood transfusion, as this can cause reactions or interfere with the blood product.
Overall, connecting packed RBCs with Y tubing to normal saline is a crucial step in ensuring the transfusion is performed safely and effectively.
