If 92yo mom in nursing home reports symptoms to me and has some worrisome speech should i call their rns or her md? prior ischemic cva, mild htn, utis

Depends: The issue here is how much intensive care your 92 year old mother wants to undergo. This is always a difficult decision since however much you are a realist and know that everyone dies, it is always difficult to let go. If the speech is changing in clarity and appropriateness and you want care, call her doctor. Nurses may or may not transmit this info to her doctors, or may or may not care.
