Final answer:
A 37-year-old obese female typist with symptoms and nerve conduction studies indicative of median nerve compression would likely show atrophy of the thenar eminence, a clinical finding consistent with Carpal Tunnel Syndrome. The correct option A) Atrophy of the thenar eminence
Step-by-step explanation:
The symptoms described by this 37-year-old obese female typist, such as pain in her left wrist and numbness, burning, and tingling sensation in her thumb, index, and middle fingers, along with some part of her ring finger, are indicative of Carpal Tunnel Syndrome (CTS).
This condition is caused by compression of the median nerve as it travels through the carpal tunnel in the wrist. Considering the nerve conduction studies reveal nerve compression, and given the occupation and symptoms of the patient, the additional clinical finding that would likely be present in this patient is A) Atrophy of the thenar eminence.
The thenar eminence muscles are innervated by the median nerve, and prolonged compression can lead to their atrophy due to inadequate nervous stimulation. This symptom matches with the typical manifestations of CTS. Radial and ulnar nerve damage would not produce the symptoms that are localized specifically to the median nerve distribution.
The additional clinical finding that would be present in this patient is A) Atrophy of the thenar eminence.
Carpal tunnel syndrome is characterized by compression of the median nerve in the wrist. The symptoms include pain, numbness, and tingling in the thumb, index, and middle fingers. The atrophy of the thenar eminence, which is the wasting away of the muscles at the base of the thumb, is a common finding in carpal tunnel syndrome.
Example: The patient may have difficulty gripping objects or experience weakness in their thumb due to the atrophy of the thenar eminence.
The correct option A) Atrophy of the thenar eminence
