Which of the following is an example of a protective transfer device?

A gait belt is specifically designed to assist in the safe transfer of patients, making it a protective transfer device. It is used to provide caregivers with a secure grip while moving or assisting patients, which helps prevent falls and injuries during transfers. The use of a gait belt promotes safety by allowing for better control and support, ensuring both the patient's and the caregiver's well-being.

In contrast, a wheelchair is primarily used for mobility rather than transferring patients; it does not offer the same level of safety support during transfers. Gloves are a personal protective item that provides infection control but do not assist with patient transfer. Bed rails are safety features on beds that may prevent falls but are not designed to facilitate the movement of a patient from one surface to another. Therefore, the gait belt stands out as the best example of a protective transfer device among the options provided.
