patient complains of tingling and pain in the thumb, index finger, and middle finger, which worsens during the day and improves with rest/sleep. Which condition is most likely?

1. A

   Ulnar neuropathy

2. B

   Cervical radiculopathy

3. C

   Peripheral neuropathy

4. D

   Carpal tunnel syndrome

Appeared in: AIIMS M.Sc. Nsg Entrance exam-2026

Explanation

• Carpal Tunnel Syndrome (CTS) is caused by the compression of the median nerve as it passes through the carpal tunnel in the wrist.
• The median nerve provides sensation to the thumb, index finger, middle finger, and the radial half of the ring finger.
• The patient's symptoms of tingling and pain in the first three fingers align perfectly with the sensory distribution of the median nerve.
• Symptoms of CTS characteristically worsen with activities that involve wrist movement and are often relieved by rest or shaking the hand.

Why Other Options Were Wrong

• Option A: Ulnar neuropathy involves the ulnar nerve, which provides sensation to the little finger and the ulnar half of the ring finger. The patient's symptoms are not in this distribution.
• Option B: Cervical radiculopathy is a pinched nerve in the neck. While it can cause symptoms in the hand, it is typically associated with neck pain that may radiate down the arm, and the sensory pattern might not be confined to a single peripheral nerve distribution.
• Option C: Peripheral neuropathy is a generalized nerve condition. It usually presents symmetrically, affecting both feet and then both hands in a 'stocking-glove' pattern, rather than being limited to the distribution of a single nerve in one hand.

• Visual 2: Anatomical Illustration - An illustration of the carpal tunnel in the wrist, showing the median nerve and flexor tendons passing through the narrow space, which helps to explain the mechanism of compression.
• Visual 3: Illustration - Illustrations of Phalen's test and Tinel's sign, demonstrating how these physical examination maneuvers are performed.

Clinical Relevance

• Nursing practice connection: Use the key finding related to Differential diagnosis of hand paresthesia based on nerve distribution to guide bedside assessment, documentation, and the next nursing action.
• Early identification of Carpal Tunnel Syndrome is crucial to prevent permanent nerve damage and muscle atrophy (especially of the thenar muscles at the base of the thumb).
• Nurses play a key role in patient education, teaching about wrist splinting (especially at night), ergonomic modifications at work, and exercises to reduce symptoms.
• What if? If the patient's symptoms were primarily in the little finger and the adjacent half of the ring finger, the most likely diagnosis would shift to Ulnar Neuropathy (Cubital Tunnel Syndrome if compressed at the elbow).

How to Approach the Question

• First, identify the key symptoms from the question stem: tingling and pain in the thumb, index, and middle fingers.
• Second, analyze the pattern of the symptoms: it worsens with activity ('during the day') and improves with rest.
• Third, recall the sensory nerve distribution of the hand. The thumb, index, and middle fingers are supplied by the median nerve.
• Fourth, evaluate the options based on this anatomical knowledge. Carpal Tunnel Syndrome is the compression of the median nerve. Ulnar neuropathy affects the other fingers. Cervical radiculopathy involves the neck. Peripheral neuropathy is more generalized.
• Finally, conclude that the symptoms described are a classic presentation of Carpal Tunnel Syndrome.

Concept Tested & Keywords

• Concept Tested: Differential diagnosis of hand paresthesia based on nerve distribution.
• Stem keywords: tingling, pain, thumb, index finger, middle finger, worsens during the day, improves with rest
• Lead-in keywords: most likely
• Clinical cues: Symptom location (thumb, index, middle finger) is a classic sign of median nerve involvement.
• Clinical cues: Symptom pattern (worse with activity, better with rest) is typical for a compression neuropathy like CTS.
