Question

Why is the cephalic vein a less desirable site for injection than the basilic vein?

1) it is usually a very small vein with poor blood flow
2) the blood must traverse the vessels in the head before reaching the heart
3) it is a deep vein and not easily catheterized
4) flow may be impeded as the patients arms are raised

Answer 1

The cephalic vein is a less desirable site for injection than the basilic vein due to its small size, longer blood route to the heart, difficult catheterization, and potential flow obstruction when the arms are raised.

Step-by-step explanation:

The cephalic vein is considered a less desirable site for injection compared to the basilic vein for several reasons:

1. It is usually a very small vein with poor blood flow. This means that there is a higher chance of difficulty in accessing the vein and a slower injection process.
2. The blood must traverse the vessels in the head before reaching the heart. This can potentially lead to a longer route for the medication to reach its intended target.
3. It is a deep vein and not easily catheterized. Deep veins are more challenging to access and carry a higher risk of complications such as infection or damage to surrounding structures.
4. Flow may be impeded as the patient's arms are raised. The cephalic vein is located in the arm, and when the arms are raised, blood flow can be partially restricted, making it more difficult to inject medication.
