Which artery, when punctured for an arterial blood gas (ABG) sample, is most commonly associated with injury to the median nerve?

Explanation

Among the arteries commonly used for ABG sampling, the brachial artery is located close to the median nerve, making it more susceptible to nerve injury during puncture. The radial artery is generally safer due to its anatomical position, while the external carotid and femoral arteries are less frequently used for ABG and have different anatomical considerations.
