Patient Ertha has shown some marked deterioration since Henry died 3 months ago. She is unkempt, more confused and agitated, cries frequently, and looks everywhere for Henry. We called her daughter-in-law Betty and she will be here shortly. Ertha was diagnosed with major neurocognitive impairment, Alzheimer's vs. Vascular etiology, about 2 years ago. Discuss the safety issues you considered when implementing care for a patient with Alzheimer's disease. What measures did you implement to ensure safe patient care? How would you assess the quality of care provided?
