healthcare workers and isolation

Mackenzie
Hi everyone! I'm a physical therapist and I work in a nursing home. I can't seem to find a definitive list of the types of precautions to avoid being pregnant. I know about TB, shingles, meningitis, but what are others? Should I avoid all respiratory-associated precautions or just airborne? 
I ask because we have a droplet patient who just came in and I'm the only PT here and I want to know for sure if I can't see them before I tell my boss no.
