Correct answer: A — Ulnar nerve
The ulnar nerve is vulnerable behind the medial epicondyle. Inferior border of the rib is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Sacral epidural space is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Median nerve is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Pleural dome near subclavian vein is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. In Primary FRCA anatomy, the tested structure should explain the block, airway sign or regional complication in the stem.
