A nurse is assisting a client with range-of-motion exercises of the hands and wrists. Which of the following terms should the nurse use when documenting the client making a fist with her hand?

A. Flexion refers to decreasing the angle between two body parts. Making a fist involves bending the fingers toward the palm, which is flexion. B. Adduction refers to moving a body part toward the midline of the body, which does not describe making a fist. C. Extension is the opposite of flexion, increasing the angle between body parts; opening the hand from a fist would be extension. D. Abduction is moving a body part away from the midline, which does not describe making a fist.
