A gurney is kind of like a bed on wheels that doctors and nurses use to move people around who can't walk or stand up. Let's say someone gets really sick or hurt and they can't move around by themselves. The doctors and nurses might put them on a gurney so they can be taken from one place to another, like from their hospital room to get some tests done. The gurney has wheels on the bottom so it can roll around, and there are usually straps and rails to keep the person safe and comfortable. Think of it like a special bed that can go for a ride and keep you safe too!
