Answer 1

During a venipuncture, blood flow stops when the second tube is attached. To address this, the PCT should ask the patient to open and close their fist.

Step-by-step explanation:

During a venipuncture, blood flow stops when the second tube is attached. The reason for this is that attaching the second tube creates a closed system, preventing blood from flowing out of the vein. To address this, the PCT should ask the patient to open and close their fist. This action helps to increase the blood flow by contracting the muscles and generating pressure to push the blood through the tube.
