Claiming your parent as your dependent does not legally obligate you to pay their medical bills, although if you paid them you can enter them into the medical expense section on your own tax return.
When you claim an adult dependent you get a $500 credit for other dependents. You do not receive a stimulus check for claiming them---and the dependent adult does not receive a stimulus check because dependents are not eligible for stimulus checks. So you need to be sure of what you are doing when you say that a parent is your dependent and know that you are really providing over half their support.
