Answer 1

The tourniquet should be placed above the wrist but below the intended venipuncture site when collecting blood from a vein in the back of the hand.

Step-by-step explanation:

In blood collection from a vein in the back of the hand, the tourniquet should be placed above the wrist but below the intended venipuncture site. This positioning helps to occlude the superficial veins and engorge the deep veins, making it easier to locate and access the intended vein. Placing the tourniquet too close to the wrist may not provide enough venous engorgement, while placing it too close to the intended venipuncture site may lead to discomfort or hinder blood flow during the collection process.
