A medical assistant is preparing to perform a venipuncture on a patient. Which of the following veins is the first choice for venipuncture due to its accessibility and low risk of complications?
- ACephalic vein
- BFemoral vein
- CMedian cubital vein
- DBasilic vein
Show answer & explanationAnswer & explanation
Correct answer: C. Median cubital vein
The median cubital vein is the preferred site for venipuncture because it is typically large, well-anchored, and has the lowest risk of nerve or artery damage compared to other common venipuncture sites.
Why the other options are wrong
- A. The cephalic vein is a good alternative but can be more mobile and prone to rolling than the median cubital.
- B. The femoral vein is located in the leg and is reserved for emergency situations or when other sites are inaccessible, due to higher risks.
- D. The basilic vein is often smaller and lies closer to nerves and arteries, making it a second choice.
Venipuncture Site Selection
The process of choosing the most appropriate vein for drawing blood, prioritizing patient safety and successful collection.
- Median cubital is first choice.
- Cephalic and basilic are secondary options.
- Avoid areas with scarring, hematomas, or IVs.
