Injury to the median nerve occurs frequently when following artery is used for taking an ABG sample _____________?
Correct answer: B. Brachial artery
- A. Radial artery
- B. Brachial artery
- C. External carotid artery
- D. Femoral artery
Explanation
The brachial artery lies close to the median nerve in the arm and cubital fossa, so brachial arterial puncture can injure it. The radial artery is preferred for ABG sampling, but its main nearby nerve risk is not the median nerve.
