NHA Certified Phlebotomy Technician (CPT)Patient PreparationMedium
A phlebotomy technician is preparing to perform venipuncture on a patient with visible scarring in the antecubital areas of both arms. Which of the following sites should the technician consider next?
- AThe brachial artery.
- BThe ventral side of the forearm.
- CThe ipsilateral antecubital area.
- DThe dorsal side of the hand.
Show answer & explanationAnswer & explanation
Correct answer: D. The dorsal side of the hand.
Scarred areas should be avoided for venipuncture due to altered tissue, poor circulation, and increased patient discomfort. The dorsal side of the hand is a common alternative site when antecubital veins are unsuitable.
Why the other options are wrong
- A. The brachial artery is not a venipuncture site; arterial punctures are typically performed for arterial blood gas analysis and require specialized training.
- B. The ventral side of the forearm often has smaller, less prominent veins and is generally not preferred over hand veins.
- C. The ipsilateral (same side) antecubital area is already stated to have scarring, making it an unsuitable choice.
Alternative Venipuncture Sites
When primary venipuncture sites (antecubital fossa) are unsuitable, alternative sites like the dorsal hand veins must be considered, following specific guidelines to ensure patient safety and specimen integrity.
- Avoid scarred, burned, or compromised areas.
- Dorsal hand veins are a common alternative.
- Foot veins may be used with physician approval, especially for adults.
Memory trick: Select the best site, avoid the bad, for a good blood draw.
