KROK 1 2021 – Question 73 · KROK (Medicine) · Human Anatomy
A 37-year old woman complains of severe pain in her left wrist and tingling sensation in her left thumb, index finger, middle finger, and a part of her ring finger. The pain started as an occasional throb that she could ignore or relieve with ibuprofen, but now the pain is much worse and wakes her up at night. She works as a typist and the pain often increases after typing all day. Her right wrist and fingers are fine. Nerve conduction studies reveal nerve compression. Which of the following nerves is most likely compressed in this patient?
- A. Ulnar nerve
- B. Musculocutaneous nerve
- C. Median nerve
- D. Axillary nerve
- E. Radial nerve
Hint
Match the area of tingling to the cutaneous territory of a nerve in the hand, then consider which nerve is vulnerable to compression at the wrist with repetitive motion such as typing.
