What should you do if a patient has an intravenous infusion in progress on one arm?
Avoid performing venepuncture on that arm.
Why should areas where two veins join be avoided for venepuncture?
Valves are often present in those areas.
What should you do if a vein feels hard during palpation for venepuncture?
Avoid that vein as it might be sclerosed, thrombosed, or inflamed.

Fully extended for adequate access to the planned site.
How far above the planned venepuncture site should you apply the tourniquet?
4-5 finger-widths above.
Why should you release the tourniquet temporarily after identifying a suitable vein?
To avoid constriction of blood flow for too long.
What is the recommended way to send blood samples to the lab for analysis?
In a plastic leak-proof bag with a completed laboratory request form

Using handwritten or preprinted labels
What information should be documented in the patient's notes after collecting blood samples?
Reason for sample, time, date and site, your name, signature and contact details
Study Notes
Blood Culture Collection Procedure
Preparation
- Cleaning the top of blood culture bottles with a separate swab before inoculation is crucial to prevent contamination.
- Maintaining aseptic non-touch technique (ANTT) when assembling equipment for blood culture collection is vital to minimize the risk of infection.
- Cleaning a procedure tray with an antiseptic wipe before starting blood culture collection ensures a sterile environment.
Patient Preparation
- Confirming the patient's name and date of birth before the procedure is essential for accurate identification.
- Adequately exposing the patient's arms is necessary for the procedure.
- Patients prone to vasovagal syncope may need to lay down during the procedure to prevent fainting.
- Asking the patient about pain and allergies (e.g., latex) beforehand is important for their safety and comfort.
Hand Hygiene
- Healthcare providers should wash their hands with alcohol gel before the blood culture collection procedure to maintain hand hygiene.
Venepuncture
- Avoid areas where two veins join for venepuncture as they may be more prone to hematoma formation.
- If a vein feels hard during palpation, it may be unsuitable for venepuncture.
- Apply the tourniquet 2-3 inches above the planned venepuncture site.
- Release the tourniquet temporarily after identifying a suitable vein to confirm patency.
- Use the cephalic or median cubital veins for venepuncture, and avoid veins with intravenous infusions in progress.
Blood Collection
- Use a tourniquet during blood culture collection to help locate the vein and facilitate blood flow.
- Add the recommended volume of 8-10 mL of blood to each blood culture bottle.
- Anchor the needle to the skin when switching between blood culture bottles to prevent blood from flowing out.
Post-Procedure Care
- If no blood flows into the bottles, stop the procedure and consult a supervisor.
- Apply gentle pressure to the venepuncture site after withdrawing the needle and apply a dressing.
- Instruct the patient to seek review if the venepuncture site becomes painful or inflamed.
- Document the patient's details on the blood sample bottles using a permanent marker, including the patient's name, date of birth, and date and time of collection.
- Record the blood sample collection in the patient's notes, including any complications or issues that arose during the procedure.
Laboratory Analysis
- Send blood samples to the lab for analysis in a timely manner, ensuring proper storage and transportation.
