The nurse planning care for a client who has been hospitalized for two weeks selects the nursing diagnosis Risk for Disuse Syndrome. While assisting the client with a bath, the nurse plans full range of motion in all the client's joints
The activity that would best support range of motion in the hand and arm is to: 1. Give the client a washcloth to wash her face. 2. Move the wash basin farther toward the foot of the bed so the client must reach. 3. Have the client brush her own hair and teeth. 4. Move each of the client's hand and arm joints through passive range of motion.
