b. tingling or pricking sensation of the hand, thumb, index, and middle fingers
c. sudden onset of numbness of the little finger

B
A tingling or pricking sensation that occurs in the hand, thumb, index, and middle fingers when the median nerve is tapped is indicative of median nerve compression (carpal tunnel syndrome). Ulnar nerve injury causes the inability of the patient to prevent the spread fingers from moving together. Numbness in the first three fingers (not the little finger) that occurs when the nurse taps the median nerve over the center of the wrist is one sign of carpal tunnel syndrome.
