A nurse in an outpatient mental health facility is assessing a child who has autism spectrum disorder. Which of the following manifestations should the nurse expect?

- A is incorrect because massaging bony prominences on the client's left side can increase the risk of skin breakdown and pressure ulcers. The nurse should avoid applying pressure to areas with impaired circulation or sensation.

- B is correct because supporting the client's left arm on a pillow while sitting can prevent edema, contractures, and nerve damage. The nurse should also encourage the client to perform active and passive range of motion exercises on their left arm.

- C is incorrect because positioning the bedside table on the client's left side can discourage the client from using their right side, which can lead to neglect and learned nonuse. The nurse should position the bedside table on the client's right side and encourage them to reach for items with their right hand.

- D is incorrect because placing the client's cane on their left side while ambulating can cause instability and falls. The nurse should place the cane on the client's right side and instruct them to move their left leg and cane together, followed by their right leg.

- A. Incorrect. The nurse should check the functioning of oxygen equipment daily, not weekly, to ensure safety and proper delivery of oxygen.

- B. Correct. The nurse should instruct the client to wear clothing made with cotton fabrics while oxygen is in use, as synthetic fabrics can generate static electricity and cause sparks that could ignite the oxygen.

- C. Incorrect. The nurse should instruct the client to avoid petroleum-based lubricants, such as Vaseline, as they are flammable and could cause burns if exposed to oxygen. The nurse should recommend water-soluble lubricants, such as K-Y jelly, instead.

- D. Incorrect. The nurse should instruct the client to store full oxygen tanks upright, not on their side, to prevent them from rolling and damaging the valve or regulator.
