Review Question - QID 217917

A 42-year-old teacher presents with one-week history of new onset weakness in her right hand. She first noticed when she was having difficulty writing on the chalk board during class. The treating orthopedic surgeon observes the patient’s difficulty performing flexion at her thumb interphalangeal joint and index finger distal interphalangeal joint. She denies any numbness or tingling to her hand and denies any trauma or injuries that she can recall. She recently saw her primary care provider for flu-like symptoms 3 weeks prior, but otherwise rarely goes to the doctor. Electrodiagnostic testing shows fibrillations and positive sharp waves in the index finger flexor digitorum profundus and flexor pollicis longus, otherwise no abnormalities. What is the best next step in management and expected sequelae?
