| What is the most important step when drawing blood from a patient? | Identify the patient |
| Name 3 things you need to know about ID bands. | Always compare the band with the requisition They must be worn by the patient Do not trust room and bed signs |
| Name the 4 steps in preparing a patient to have their blood drawn. | Reassure the patient. Explain blood draw procedure. Do not explain the test! Do not say procedure is painless! |
| Name 4 conditions you must verify with the patient before performing the blood draw. | Fasting Medications Activities Notice any unusual conditions FAMN (Famine) |
| When drawing blood, there are 3 things you can do to ensure the patient has been positioned comfortably and that the site of blood draw is well supported. What are they? | Place pillow under arm Place fist under elbow Place arm at downward angle to prevent reflux |
| Name 3 things you can do to ensure the safety of the patient when drawing blood? | Patient is sitting or lying down Remove objects from patient’s mouth Be alert for syncope (signs of fainting) |
| Name 5 things to keep close at hand when drawing blood from a patient. | Antiseptic pads Gauze Bandage Needle disposal system Examination requisition form Extra tubes in case of loss of vacuum Attach needle to adapter |
| Name five steps in applying a tourniqet to a patient when drawing blood. | Apply tourniqet for no more than 1 minute Apply tourniquet for site selection Release it for 2 minutes Reapply the tourniquet when ready to draw blood Release when blood flows |
