Answer 1

If a blood draw is needed from a patient with an open IV line, the sample is typically obtained below the IV.

Step-by-step explanation:

If a blood draw is needed from a patient with an open IV line, the sample would typically be obtained below the IV. The reason for this is that IV bags are usually placed higher than the entry point into the arm to allow the fluid to enter the arm. However, for blood collection, the bag is placed below the donor to allow blood to flow easily from the arm to the bag. This is the opposite direction of flow compared to the IV fluids.
