You are caring for a 92-year-old female patient who was admitted to the hospital 1 day after outpatient cataract surgery. The patient who lives in an assisted living facility became very confused and agitated and was found wandering in the lobby of the building in her nightgown. The patient refused to return to their room and stated that there were "bad men" in the room. The patient has a history of dementia, diabetes, heart failure, and is on seven different medications. The patients lost their spouse 1 year ago. The nurse suspects that the patient is experiencing delirium. What are the patient's risk factors for delirium? (Select all that apply.)

A. Recent cataract surgery is a risk factor because acute illness, surgical procedures, and changes in routine or environment can trigger postoperative delirium, especially in older adults. B. History of dementia is one of the strongest risk factors for developing delirium due to decreased cognitive reserve. C. Age of 92 increases vulnerability to delirium due to general age-related changes in the brain and increased susceptibility to stressors. D. Female gender is not an independent risk factor for delirium; both men and women can be equally affected, though some studies suggest slightly higher risk in men. E. Residing in an assisted living facility may be associated with other risks, but it is not a direct risk factor for delirium. The environmental change (e.g., hospitalization) is more relevant.
