What is the function of a call light in a healthcare setting?

The function of a call light in a healthcare setting is to signal for help. A call light system is essential in hospitals, nursing homes, and other healthcare facilities as it enables patients to alert nursing staff or caregivers when they need assistance. This may include requests for help with personal care, medication, or emergencies. The prompt response facilitated by the call light can significantly impact patient comfort, safety, and overall care quality.

In contrast, providing light in dark areas, monitoring patient health, and controlling room temperature do not accurately capture the primary purpose of a call light. While lighting may be important for visibility, call lights specifically serve the function of communication between patients and healthcare staff, ensuring that patients can easily request help as needed.
