Final answer:
In a healthcare setting, wheelchairs not in use should be locked and have their leg rests removed to ensure safety and prevent obstructions.
Step-by-step explanation:
In a healthcare setting, when wheelchairs are not in use, the appropriate action is to lock them and remove leg rests. This precaution ensures that the wheelchair remains safe and does not pose a tripping hazard or obstruct pathways. Removing the leg rests helps to prevent potential injuries that can occur if someone were to bump into them, and it makes the wheelchair more compact for storage. Locking the wheelchair also prevents it from rolling away or causing an accident.
