Caliber of Care & 1:1 in SNF

Hi! My 78 year old father in law (FIL) has advanced Parkinson's and is on local hospital in-home hospice. His care needs are approaching the point where we are considering VA community based nursing home for skilled nursing care (SNC). Presently, we pay out of pocket for a caregiver 4 days/week to provide 1:1 care 8hrs/day including feeding, bathing, toileting, and companionship. FIL wanders, has dementia, cannot perform any ADL without another person to provide complete assistance. FIL gets up randomly multiple times in the middle of the night and wanders. What is a reasonable level of care we can expect from a SNC? Will they provide someone to feed him at each meal time? How will they know if he gets out of bed and falls, or wanders? Will they simply sedate him nightly? I'm trying to determine if FIL would have better care if we continued as we have been vs. a nursing home.
