What are the basilic veins commonly used for?

1. Blood donation

2. Drug administration

3. Blood clotting tests

4. Sample collection

The correct answer is: Sample collection

The basilic veins are primarily utilized for sample collection due to their anatomical location and size, which provide easy access for venipuncture. These veins are situated deeper within the arm, close to the brachial artery, and are larger than other veins in the forearm and hand, making them suitable for drawing blood. When performing venipuncture for blood samples, healthcare professionals often choose veins that are not only accessible but also have sufficient diameter to accommodate the volume of blood needed for various laboratory tests. This vein allows for the efficient collection of blood without risking damage to surrounding tissues, which is crucial for maintaining the integrity of the sample. In contrast, while the basilic vein could potentially be used for drug administration, it is less common due to its deeper location and potential proximity to arteries and nerves. Blood donation generally involves larger veins such as the median cubital vein, which is typically more visible and accessible. Blood clotting tests may require specific sample collection protocols, but the basilic vein's primary role remains in routine blood sampling.
