Answer:
Call light
Step-by-step explanation:
Residents in hospital sometimes do not have the luxury to move freely. There are occurrences when they felt so weak to the point where they can't talk or stand on their own legs. So, when residents suddenly need something, they might need the help of other people.
So, every hospitals will provide a call light on their hand. The call light contains buttons that will notify the nurses so they can come to the resident's room and take care of their needs.
