Question

Match List I (Clinical Conditions) with List II (Nerves involved) and select the correct answer using the codes given below the lists:

List I (Clinical Conditions)	List II (Nerves involved)
A. Wrist drop	1. Ulnar nerve
B. Winging of Scapula	2. Radial nerve
C. Pointing index	3. Long Thoracic nerve
D. Claw hand	4. Median nerve

Codes:

• A. A-2, B-3, C-4, D-1
• B. A-1, B-4, C-3, D-2
• C. A-2, B-4, C-3, D-1
• D. A-1, B-3, C-4, D-2

Hint:

Radial nerve gives wrist drop, long thoracic nerve gives winging of scapula, median nerve gives a pointing index, ulnar nerve gives a claw hand.

Answer 1

The Correct Option is A

This question links four hand or shoulder deformities to the nerve that causes each one, then asks which answer code lists all four pairs correctly.

1. Wrist drop: The wrist and fingers cannot extend because the radial nerve, which supplies the extensor muscles of the forearm, is damaged. So this pairs with the radial nerve.
2. Winging of Scapula: The shoulder blade sticks out backward because the long thoracic nerve, which supplies serratus anterior, is injured, so this pairs with the long thoracic nerve.
3. Pointing index: When trying to make a fist, the index finger stays pointed straight because the median nerve, which flexes the index and middle fingers, is damaged, so this pairs with the median nerve.
4. Claw hand: The ring and little fingers curl into a claw shape because the ulnar nerve, which controls most small hand muscles, is damaged, so this pairs with the ulnar nerve.

Putting the four pairs together gives wrist drop with radial nerve (A-2), winging of scapula with long thoracic nerve (B-3), pointing index with median nerve (C-4), and claw hand with ulnar nerve (D-1). This exact set of pairs is code (a).

Let's summarize:

• Radial nerve damage gives wrist drop, long thoracic nerve damage gives scapular winging.
• Median nerve damage gives a pointing index, ulnar nerve damage gives a claw hand.

So the correct code is A-2, B-3, C-4, D-1.
