A patient prescribed to receive two units of packed red blood cells is to receive a dose of intravenous medication between the two units. How would the nurse administer the medication?

Administering intravenous medication to a patient who is receiving packed red blood cells requires careful consideration to ensure safety and maintain the effectiveness of both the blood transfusion and the medication. Using another IV line is the most appropriate method in this context. This approach prevents any potential interactions between the blood product and the medication, which could compromise the safety of the transfusion and lead to adverse reactions.

Additionally, using a separate IV line ensures that the flow rates of both the transfusion and the medication can be managed effectively without affecting each other. It also mitigates the risk of contamination and helps maintain the integrity of the packed red blood cells. This method aligns with best practices in nursing care and transfusion protocols to prioritize patient safety.

Flushing the same line between units is generally discouraged for medications, especially those that could potentially alter the properties of the blood product or risk incompatibility. Administering the medication intramuscularly would not be appropriate in this situation, as the medication is intended to be given intravenously. Delivering the medication during the transfusion could interfere with the blood product's infusion, which is not advisable.
