How to care for a resident who doesn't speak English?

So I have a resident that only speaks Spanish, he does not speak English at all. Hes easily agitated (yesterday he threw all 3 of his meal trays at me as well as his cup of ice water), hes also a very high fall risk (yesterday he rolled out of bed about 15 minutes after I rounded on him). Yesterday was my first day on my own and off orientation, it was also my first day working with this assignment. Today i have the same assignment, but im struggling with this resident in particular bc of the language barrier.

I feel guilty bc yesterday when he rolled out of bed, one of my coworkers who does speak Spanish helped me w the hoyer to get him back in bed. She asked why he got on the floor and he said bc he was trying to turn the heat on bc he was cold. When I checked on him b4 he fell, he kept saying "ocho uno" and thinking back on it i believe he was asking for the heat to be turned to 81, but for some reason I had assumed he was talking about he wanted the TV to be turned to 81.

Anyway, today is pretty much the same deal. Hes agitated, I dont know what he wants, and he keeps trying to tell me. My facility just says use translating apps, but theyre not picking up what he says. The only thing I know to do is to constantly get my coworker who speaks Spanish to help me but she has her own assignment and is busy and I hate to keep bothering her every time I need help with this resident.

Does anyone have any tips or experience with dealing with a language barrier for someone youre trying to care for?
