NHA Certified Phlebotomy Technician (CPT)Patient PreparationHard
A phlebotomy technician is preparing to draw blood from a patient's arm. Upon palpation, the technician identifies a vein that feels hard, cord-like, and lacks resilience. What is the MOST appropriate action?
- AAttempt to draw from the vein using a smaller gauge needle.
- BApply a warmer compress to the arm to soften the vein.
- CSelect an alternative venipuncture site.
- DProceed with the draw, as it may still yield a sample.
Show answer & explanationAnswer & explanation
Correct answer: C. Select an alternative venipuncture site.
A vein that feels hard, cord-like, and lacks resilience is likely sclerosed or thrombosed. Attempting to draw from such a vein is often unsuccessful, painful for the patient, and can lead to damage, hematoma, or nerve injury. The most appropriate action is to select an alternative, healthier site.
Why the other options are wrong
- A. A smaller gauge needle won't change the condition of a sclerosed vein and will likely still be unsuccessful or cause damage.
- B. A warm compress helps distend healthy veins but will not soften a sclerosed or thrombosed vein.
- D. Proceeding with a compromised vein is unprofessional and risks patient harm and an unsuccessful draw.
Sclerosed/Thrombosed Veins
Veins that are hardened or clotted, often due to repeated venipuncture, inflammation, or disease.
- Feel hard, cord-like, and lack resilience.
- Unsuitable for venipuncture.
- Can lead to unsuccessful draws, pain, and complications.
Memory trick: Hard and cordy? That vein's no good, buddy!
