Final answer:
The correct order of vein selection for venipuncture in the antecubital fossa is the median cubital vein first, followed by the basilic vein, and the cephalic vein last (option 3).
Step-by-step explanation:
When inspecting the antecubital fossa to select a vein for venipuncture, the correct order of vein selection is usually the median cubital vein, followed by the basilic vein, and lastly the cephalic vein. Therefore, the correct answer is option 3) Median cubital vein, Basilic vein, Cephalic vein. This sequence is generally preferred because the median cubital vein is often the most superficial and easiest to palpate; it is located in the antecubital fossa, making it a common site for drawing venous blood since it is less likely to roll and has fewer nerves nearby. The basilic vein is considered next as it is also easily accessible, though care should be taken due to its proximity to nerves and arteries. The cephalic vein, though also superficial, is often the last choice as it may be smaller and more difficult to palpate in some individuals.
