49. A phlebotomist is obtaining a venipuncture specimen and has decided to use the vein which lies on the outer edge of the arm. Which of the following veins has the phlebotomist selected?
Answer: A
The phlebotomist has selected the Cephalic vein.
The Cephalic vein is located on the outer edge of the arm, making it the correct choice for the phlebotomist's selection in this scenario.
A) Cephalic
This option is correct as the Cephalic vein is indeed situated on the outer side of the forearm and is commonly used for venipuncture due to its accessibility and size. It runs along the radial side of the arm, making it a suitable choice for drawing blood.
B) Median cubital
The Median cubital vein, while often the first choice for venipuncture due to its central location in the antecubital fossa, is not located on the outer edge of the arm. This vein lies more centrally and is not the correct vein selected by the phlebotomist.
C) Basilic
The Basilic vein is found on the inner side of the arm, closer to the body. Although it can be used for venipuncture, it does not correspond to the outer edge location specified in the question, making it an incorrect choice.
D) Dorsal
The Dorsal veins refer to those located on the back of the hand and wrist, rather than on the arm itself. This option does not align with the description of the vein selected by the phlebotomist and is therefore incorrect.
Conclusion
The Cephalic vein is the only option that fits the description of being located on the outer edge of the arm, which is why it is the correct answer. The other options do not match this anatomical location, confirming that they are not suitable choices for the phlebotomist's selection.
