Occupational health nursing is when a nurse helps businesses make sure that their employees are healthy and safe while they are working. This means that the nurse makes sure that the employees aren't getting sick from things that they are exposed to at work like chemicals or heavy lifting. The nurse also makes sure that the employees understand how to stay safe and healthy while they work. They may give them training on how to lift things properly, wear safety equipment, and avoid accidents. They might also help with things like regular health checks, immunizations, and managing injuries that happen at work. Overall, occupational health nurses are like protectors of worker's health and safety.
