Final answer:
A phlebotomist should assemble a winged infusion set and adapter (option B) for a hand draw. The winged infusion set is used because it allows for a more delicate venipuncture in the hand, suitable for difficult or fragile veins.
Step-by-step explanation:
A phlebotomist is preparing to perform a hand draw. The correct equipment for this procedure is a winged infusion set and adapter.
In a phlebotomy setting, a phlebotomist is a professional trained to draw blood. There are different types of blood collection techniques. When a phlebotomist performs a venipuncture, typically of a surface vein in the arm, they may use an evacuated tube system (ETS) with a needle and adapter, or a syringe and vacutainer, which allows for multiple tubes of blood to be collected during one puncture.
For a hand draw, particularly when veins may be difficult to access or are fragile, a winged infusion set (also known as a butterfly needle) is often used because its design allows for more delicate access to the veins in the hand. This is coupled with an adapter to allow the blood to flow into the collection tube.
If only a small quantity of blood is required for the test, such as in a capillary stick, then a lancet and microtainer would be appropriate. This method is commonly used for fingerstick or heelstick blood samples in infants.
