Final answer:
Nurses can reposition the client's arm or adjust the IV solution height to at least 0.24 meters above the entry point to ensure an adequate flow of fluids into the arm, which differs from blood collection practices where the bag is below the donor's arm.
Step-by-step explanation:
When administering intravenous (IV) therapy and there is no infiltration, a nurse may need to adjust the position of the client's arm or the height of the IV solution to ensure proper flow. The pressure necessary for the fluid to enter the arm can be achieved if the IV bottle's surface is at a certain height above the entry point of the needle. According to the provided reference, the IV bag must be placed at least 0.24 meters above the entry point into the arm for the fluid to just enter the arm. However, it is common practice to position IV bags higher than the minimum requirement to ensure a consistent flow. In contrast to this, blood collection bags are often placed below the level of the donor's arm, facilitating the flow of blood from the arm to the bag, which is the reverse of the infusion process.
