A medical assistant is preparing to perform a venipuncture on a patient. Which of the following veins is the most commonly used for routine venipuncture?
- AFemoral vein
- BMedian cubital vein
- CCephalic vein
- DBasilic vein
Show answer & explanationAnswer & explanation
Correct answer: B. Median cubital vein
The median cubital vein is the most commonly used and preferred site for routine venipuncture due to its accessibility, size, and typically being well-anchored.
Why the other options are wrong
- A. The femoral vein is located in the groin area and is generally reserved for emergency situations or when other sites are inaccessible, not routine venipuncture.
- C. The cephalic vein is another alternative, often used when the median cubital is not suitable, but it can be more prone to rolling.
- D. The basilic vein is an alternative but is often closer to nerves and arteries, making it less preferred.
Median Cubital Vein
The large, superficial vein located in the antecubital fossa (inner elbow) that is the primary site for routine venipuncture.
- Most accessible and visible vein.
- Typically well-anchored and less likely to roll.
- Fewer nerves and arteries nearby compared to other arm veins.
Memory trick: Many Choices, Best Choice: Median Cubital.
