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.

Correct Answer is B

Explanation

A. The Glasgow Coma Scale assesses a patient's level of consciousness, not specifically limb weakness.
B. A complete neurological examination would involve assessing cranial nerves, motor and sensory functions, reflexes, coordination, and gait, which are essential when a client presents with unilateral weakness in the arm and leg.
C. A muscular examination might focus more on muscle strength and tone but might not cover the breadth of neurological assessment needed in this scenario.
D. Neurologic recheck examination suggests a reassessment after an initial neurological exam but doesn’t specify the need for a comprehensive evaluation.

A. estimate the degree of flexion and extension in each joint. B. measure the degree of force that it takes to overcome joint flexion or extension. C. apply an opposing force when the individual puts a joint in flexion or extension. D. observe muscles for the degree of contraction when the individual lifts a heavy object.

Correct Answer is C

Explanation

A. Estimating the degree of flexion and extension in each joint primarily assesses the range of motion, not specifically muscle strength.
B. Measuring the degree of force required to overcome joint flexion or extension may assess resistance but doesn't directly evaluate muscle strength.
C. Applying an opposing force when the individual puts a joint in flexion or extension is an accurate method to assess muscle strength, as it evaluates the force the muscle can generate against resistance.
D. Observing muscles for contraction while lifting a heavy object evaluates muscle usage but doesn’t offer a standardized way to assess muscle strength.
