"I'll verify the physician's order for the specific blood product."

Choice A rationale:

Selecting any available intravenous site for the transfusion without verifying the physician's order is unsafe and can lead to administering the wrong blood product or causing an adverse reaction in the patient.

Verifying the order is a critical step in ensuring patient safety during a blood transfusion.

Choice B rationale:

Using a blood administration set with additives may be necessary in some cases, but it is not the primary action the nurse should take before starting the transfusion.

Verifying the physician's order is the first and most crucial step.

Choice C rationale:

Verifying the physician's order for the specific blood product is essential to confirm that the correct blood type and unit are being administered to the patient.

This step ensures ABO and Rh compatibility and minimizes the risk of transfusion reactions.

Choice D rationale:

Administering the transfusion as quickly as possible is not appropriate and can be dangerous.

Transfusions should be administered at a controlled and appropriate rate to monitor for any adverse reactions.

Rushing the transfusion can increase the risk of complications.
