Which of the following is a lifting and moving device used in emergency medical services?

The correct choice, which indicates that all options listed are lifting and moving devices used in emergency medical services, is accurate because each of these tools serves a specific purpose within this context.

A wheeled stretcher is commonly utilized in emergency situations to transport patients who may be unconscious, injured, or unable to walk. Its design allows for smooth movement and ensures the patient remains stable and supported during transit.

A stair chair is specifically designed for safely transporting patients up and down stairs. It features a lightweight structure and a design that allows for easy maneuverability in tight spaces while providing support to the patient.

The scoop (or orthopedic) stretcher is another essential device that can be split into two halves, enabling it to be placed around the patient without the need for lifting the entire body. This is particularly beneficial for patients with suspected spinal injuries, allowing for safe and effective immobilization and transfer.

Each of these devices plays a vital role in ensuring safe transport and movement of patients by emergency medical responders. Therefore, acknowledging all of them as lifting and moving devices used in EMS reflects a comprehensive understanding of the tools available in emergency medical situations.
