Explanation:

1. If a stat test is ordered and the patient is not in their room, the appropriate action is to leave the request at the nurse's station for the nurse to perform the draw. This is standard hospital - protocol to ensure proper communication and patient - care coordination.
2. The blood bank may require special patient ID due to the critical nature of blood transfusions and the need to prevent transfusion errors.
3. Collapsed veins can be caused by a too - large needle for the vein, too much vacuum asserted on the vessel, or the plunger being pulled too quickly as all these factors can disrupt the integrity and pressure within the vein.
4. When an artery is inadvertently stuck during collection, the sample should not be labeled as usual because arterial and venous samples have different characteristics and uses.
5. Hemolysis can be caused by vigorously mixing the tubes as this can damage the red blood cells.
