Which type of protective device is commonly found in bathrooms and wet locations within a medical facility?

The correct choice, ground-fault circuit-interrupter (GFCI), is specifically designed to protect individuals from electric shock in areas where water and electricity may come into contact, such as bathrooms and wet locations. GFCIs are sensitive devices that quickly interrupt the electrical circuit when they detect an imbalance between the outgoing and incoming electrical current, which often indicates that current is flowing through an unintended path, such as through a person who may be standing on a wet surface.

In medical facilities, where patient safety is critical, the installation of GFCIs in bathrooms and similar environments is essential to prevent electrical hazards. Their use significantly reduces the risk of severe injury or electrocution, making them a core safety feature in areas prone to moisture.

Other devices listed, such as an uninterrupted power supply, line isolation monitor, and surge suppressor, serve different purposes. An uninterrupted power supply provides backup power to critical equipment, a line isolation monitor helps detect faults in electrical systems, and a surge suppressor protects equipment from voltage spikes. However, none of these devices specifically address the direct need for electrical safety in wet locations, making them less suitable for this particular context.
