Hands-on Care Needed For My Father In Green Valley

About who needs care: My father has cardiomyopathy / heart failure. Is coming home from the hospital today or tomorrow and is going to be wearing a difibrillator "life vest" until they get him a pace maker installed. My mom needs to go to her appointments periodically and we need a licensed nurse to stay with him while she is away on appointments, etc. About the care needs: He is frustrated with his new situation and needs a sweet and gentle yet very confident seasoned nurse / helper. He might need absolutely nothing at all, but may need help with his oxygen or to be reminded to keep his vest on at all times. He has no mental impairment whatsoever. He is 83. Services needed include: meal preparation, errands / shopping, light housekeeping, feeding, and bathing / dressing.
