I have been a caregiver since 2006 when my mother had a bleeding stroke and still am a caregiver 20 hours, some days more.

You will have to learn hundreds of challenging “skills”.

Sadly, you now need to pay a lawyer to educate you on USA laws and state laws.

Look for an “Elder Care” lawyer.
Expect to pay $400 or more, but in your situation your mother needs you to know this “skill.”

Consider taking a 2nd job for 90 days at a nursing home.
This is a way to be paid to “learn the ropes”.
Prior to doing this you need to pass the “Certified Nursing Assistant” or CNA exam, which is doable.

You need to understand what goes on in a nursing home from 10 PM to 6 AM.
