Final answer:
To assist individuals who are weak or have mobility concerns, a walker is the common safety device employed to provide support and stability when transferring or moving.
Step-by-step explanation:
The common safety device used to transfer residents who are weak, unsteady, or uncoordinated is typically a walker. A walker provides a stable frame that a person can grasp and use for support while moving. It enhances balance by increasing the base of support. As infants learn to hold their bodies erect, they might use aids like a push toy for support, similar to how a walker operates for adults requiring assistance. Additionally, stability can be improved by widening the stance, lowering the center of gravity, and using devices like canes and crutches to aid in movement for those with compromised mobility.
