Companion Care Needed

About who needs care: My father in law is currently in a memory care facility but just had a fall with 5 night hospitalization. He has been discharged back to his facility but is having major cognitive changes. We are hoping these changes are due to the significant amounts of sedatives he was administered in the hospital, and hoping that given a few days that he will clear back to baseline. Looking for 1:1 supervision for a week for safety. Will pay out of pocket without insurance. About the care needs: Familiarity with dementia- communication with facilities staff and our family.
