The device that is MOST likely to be considered a physical restraint is:
B. Lap belt
Explanation:
1. A lap belt is a type of physical restraint used to limit a person's movement by securing them in a seated position. It is commonly used in vehicles, wheelchairs, and certain medical settings to prevent falls or injuries by restricting the person's ability to stand or move freely.
2. Non-skid socks (Option A) are not typically considered physical restraints as they are designed to provide traction and prevent slipping, rather than restricting movement.
3. A call light (Option C) is a communication device that allows individuals to call for assistance but does not physically restrain a person.
4. A walker (Option D) is an assistive device used for support and mobility but is not a physical restraint as it is meant to aid movement rather than restrict it.
In summary, a lap belt is the most likely device among the options provided to be considered a physical restraint due to its function of restricting movement and confining a person to a specific position.
