Companion Care Needed

My mother will be coming out of a major surgery to remove her cancer. I basically just need someone to check on her, make sure she ate and took her pills and isn't in need of anything while she recovers. At the moment, I am unsure when she will be released from the hospital after surgery- and how much care and kind of care she will need till closer to surgery date and after. I will most likely be making a decision last minute and will need someone to work very urgently. Depending on how she is after- will outline what we need in a caregiver and frequency could change as well.
