A male client is admitted to the unit with a possible diagnosis of delirium. Which statement by the client's wife best supports the diagnosis?

Choice A Reason:Grief following the death of a loved one can lead to a variety of emotional and physical symptoms, but it does not typically result in delirium. The symptoms of grief can include sadness, difficulty sleeping, and a loss of interest in activities, but these do not align with the acute cognitive changes seen in delirium.Choice B Reason:Chronic forgetfulness that has been present for years suggests a progressive cognitive decline rather than delirium, which is characterized by a sudden onset. Conditions such as Alzheimer's disease or other forms of dementia are more likely to cause long-term memory issues.Choice C Reason:The sudden onset of behavioral changes is a hallmark of delirium. Delirium is an acute confusional state that typically occurs rapidly and can fluctuate throughout the day. It is often caused by a medical condition, medication, infection, or substance withdrawal.Choice D Reason:While it is true that the risk of delirium increases with age, it is not a normal part of aging. Delirium is always considered a medical emergency that requires immediate attention to identify and treat the underlying cause.
