Study Notes
Blood Sample Collection
- The specific order of draw is crucial when collecting multiple blood samples to avoid cross-contamination of additives between tubes and ensure accurate test results.
- The order of draw helps prevent carryover of additives from one tube to another, which can affect test outcomes.
- Correct ordering also ensures that the blood samples are not compromised, maintaining the integrity of the testing process.
Preparation for Venipuncture
- Verify patient's identification and test request
- Review medical history for bleeding disorders or medications affecting blood clotting
- Wash hands thoroughly and wear gloves
- Choose a suitable vein for venipuncture (median cubital or cephalic vein)
Venipuncture Equipment
- Needles (21-23 gauge)
- Syringes or vacuum tubes
- Tourniquet
- Gauze
- Antiseptic wipe
- Bandage or cotton ball
Venipuncture Procedure
- Restrict blood flow with a tourniquet 3-4 inches above the venipuncture site
- Clean the skin with an antiseptic wipe
- Insert needle at a 15-30° angle, bevel up, into the vein
- Collect blood slowly by pulling back the plunger or using a vacuum tube
- Remove the needle and apply gentle pressure to the site with a gauze or cotton ball
- Release the tourniquet after the needle is removed
- Label the sample with the patient's identification and test request
Post-Procedure Care
- Apply a bandage to the site
- Monitor the patient for bleeding, discomfort, or other complications
- Dispose of used needles and equipment properly
Venipuncture Complications
- Hematoma (bleeding under the skin)
- Nerve damage
- Infection
- Fainting (vasovagal response)
- Allergic reactions to equipment or cleaning agents
