I work in LTC with geriatric patients, I've had incidents where I've been hit by residents and it usually doesnt faze me. But recently I was screamed as and hit, also water thrown at me while trying to bring a resident her pills. I had asked her earlier what time and she agreed to the time. When I arrived she wanted to keep the pills on her bed and take them later. I nicely asked her to please return the pills as it is against policy for nurses to leave pills with residents. At this point she started to yell and hit me. When speaking to her with another staff present 30 minutes later, the resident agreed that yes she did hit me and she was not sorry, that we cant control her. Keep in mind I had used a very gentle approach with this resident. Looking for some advice on how not to take incidents like this personal and how I can keep these incidents from happening in the future. Thank you
