Hands-on Care Needed For My Father In Los Angeles

I'm looking for overnight care for my father in his 70s who lives with my mother (from around 10 p.m. to 6AM). Usually they are sleeping but we need someone to make sure my father doesn't wander at night. Most of the job will just be sitting outside their room and making sure he doesn't leave the bedroom. Important - experience with managing and administering medication is required. Assistance with bathing is one of our requirements. Looking for a caring and compassionate companion. Preferences for a caregiver who is comfortable with pets and CPR / first-aid trained.
