Venipuncture Steps Checklist
Tick each step as you practice. This is the order certification exams test.
- Review the requisition for tests, timing, fasting and special handling, then assemble supplies.
- Identify the patient with two identifiers: they state full name and date of birth; match both to the wristband and requisition.
- Perform hand hygiene, introduce yourself, explain the procedure, and ask about latex allergy and fainting history.
- Position the patient seated in a phlebotomy chair with an armrest, or lying down, arm extended downward.
- Apply the tourniquet 3–4 inches (7.5–10 cm) above the site for no longer than 1 minute; the patient makes a fist without pumping.
- Select the vein by palpating with your index finger. The median cubital vein is the first choice.
- Put on gloves, cleanse the site with 70% isopropyl alcohol, and let it air dry completely.
- Inspect and assemble the needle, then anchor the vein by pulling the skin taut below the site with your thumb.
- Insert the needle bevel up at a 15–30 degree angle in one smooth motion.
- Fill tubes in the order of draw. Release the tourniquet and have the patient open the fist as soon as blood flow is established.
- Gently invert each additive tube as soon as it comes off the holder.
- Remove the last tube, place gauze over the site, withdraw the needle, activate the safety device, and discard it in the sharps container.
- Apply pressure until bleeding stops, then bandage.
- Label every tube in the presence of the patient before leaving, then remove gloves and perform hand hygiene.
Key numbers
- Tourniquet: 3–4 in (7.5–10 cm) above the site, on 1 minute max. Over 1 minute: release it and wait 2 minutes before reapplying.
- Needle: 15–30°, bevel up.
- Vein choice: median cubital first, then cephalic; basilic last (near the brachial artery and median nerve).
- Palpate with the index finger, never the thumb (it has its own pulse).
Sites to avoid
- Arm with a fistula or graft
- Same side as a mastectomy
- Above an IV (if unavoidable: below it, and document)
- Edema, hematoma, scars or burns
- Areas that feel hard or pulsate
