Sample item

For hand and forearm surgery, local anaesthetic is deposited around the median, ulnar and radial nerves near the artery at the armpit, and the musculocutaneous nerve is blocked separately in the coracobrachialis. Which block is this?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Axillary block

This approach is at the terminal branch level, so it spares the shoulder and avoids phrenic nerve palsy. The musculocutaneous nerve leaves the sheath early and needs a separate injection.

Option by option

  • A. Axillary block (correct)

    Correct. The terminal-nerve approach at the armpit fits.

  • B. Cervical plexus block

    Cervical plexus block supplies the neck.

  • C. Supraclavicular block

    Supraclavicular block is at trunk-division level above the clavicle.

  • D. Interscalene block

    Interscalene block anaesthetises the shoulder and often causes phrenic palsy.
