I used to work at a hospital where Chinese languages and Spanish were the most common languages. I already speak English and Spanish but I used my basic Mandarin only for introductions to bridge the distance between us before th use of an interpreter.

Hello! My name is NAME, I am a speech-language pathologist and I am here to do an X evaluation that your doctor ordered. Do you have any questions before we start?

Buenos días me llamo X, soy terapeuta del habla y del lenguaje y vengo a completar una evaluación de X que su médico ordenó. Tiene alguna pregunta antes de que empecemos? (Pretty much the same as above)

你好！我叫NAME，我是語言治療師，我要做X的評估，我現在要給翻譯打電話幫助我們 (this is me introducing myself and saying I'm gonna call the interpreter to help us because my Mandarin is crapola; my multilingual coworkers vetted my introduction as well)

I would never advocate using a language you're not comfortable with for your evaluation/treatment, but I find that doing a short introduction or greeting tends to exude more warmth and shows that you're not as impersonal as some of the staff who don't speak their language

Overall, keep it short and sweet cause you rarely have the luxury of time in acute care
