Question

A bottle is hung at a higher position next to the patient’s bed during the blood transfusion.​

Answer 1

It is standard practice at many hospitals to follow blood component transfusions with a normal saline (0.9% NaCl) flush. This serves the dual purpose of administering to the patient any residual blood left in the administration set (up to 40 mL), and it flushes the line for later use.
