The nurse suspects that a client has carpal tunnel syndrome and prepares to conduct the Phalen test. What instructions should the nurse give the client to perform the Phalen test?

Plantarflex the foot

Dorsiflex the foot

Hold both hands back to back while flexing the wrists 90 degrees for 60 seconds

Hyperextend the wrists with the palmar surface of both hands touching, and wait for 60 seconds

Answer and Explanation

The Correct Answer is C

A.   Plantarflexion and dorsiflexion refer to movements of the foot and are unrelated to the Phalen test.
B.   Hyperextension of the wrists with the palmar surfaces touching is not the correct maneuver for the Phalen test.
C.   The Phalen test involves holding both hands back to back while flexing the wrists at a 90- degree angle for about 60 seconds, which may induce symptoms of carpal tunnel syndrome in those affected.
D.   Hyperextending the wrists with the palms together doesn’t simulate the stress on the median nerve in the same way as the Phalen test.

A. Motor component of CN X and sensory component of CN VII B. Motor and sensory component of CN XI C. Motor component of CN IV D. Motor component of CN VII

Correct Answer is D

Explanation

A. Dysfunction of the motor component of CN X (vagus nerve) and sensory component of CN VII (facial nerve) would present with different symptoms, such as difficulty swallowing and impaired taste sensation, not the observed facial asymmetry and puffing of cheeks.
B. CN XI (accessory nerve) dysfunction primarily affects the sternocleidomastoid and trapezius muscles and wouldn't cause the observed facial asymmetry.
C. Dysfunction of CN IV (trochlear nerve) leads to issues with downward and inward eye movement, not the facial asymmetry described.
D. Dysfunction of the motor component of CN VII (facial nerve) leads to facial asymmetry during expressions and difficulty controlling facial muscles, which matches the observed findings.
