One of the most critical responsibilities for nursing homes that choose to accept cognitively impaired patients is to pro-actively do everything and anything it takes to protect them.
Many studies show that approximately 80% of nursing home residents suffer from at least some degree of cognitive impairment.  Many suffer in more profound ways.  Quality nursing homes engage in regular assessments and supervision to protect all residents.  When residents either display violent tendencies or the potential for violence, they must be supervised, treated and have constant attention made to their care plans.  Many times, there are solutions to such behavior and staff must always be on the lookout for new or changing issues.
