A nurse is admitting a client to the hospital unit. Which one of the following elements of the client's history and physical assessment increases the risk for the development of delirium?

A. Persistent headache and aggression: While persistent headache and aggression can occur following a traumatic brain injury (TBI), these symptoms are not specific to mild TBI. Aggression is more commonly associated with severe TBI, and persistent headache can occur across the spectrum of TBI severity.

B. Headache and confusion: Headache and confusion are common manifestations of mild TBI. Following a mild TBI, individuals often experience headache, which may be mild to moderate in intensity. Confusion, disorientation, and difficulty concentrating are also typical symptoms of mild TBI due to the transient disruption of cognitive function.

C. Loss of vision and depression: Loss of vision and depression are less commonly associated with mild TBI. These manifestations may occur in more severe cases of TBI or with specific types of brain injury affecting visual pathways. However, they are not typically indicative of mild TBI.

D. Seizures and extremity weakness: Seizures and extremity weakness are more indicative of moderate to severe TBI rather than mild TBI. While mild TBI may result in brief loss of consciousness, seizures and significant extremity weakness are less characteristic of mild TBI and are more commonly observed with more severe brain injuries.

A. Restlessness: Restlessness is a common behavioral manifestation in clients with Alzheimer's disease. It can be caused by various factors, including confusion, agitation, discomfort, or unmet needs. Restlessness may manifest as pacing, fidgeting, or difficulty sitting still.

B. Aggression: Aggression, including verbal or physical aggression, is a behavioral manifestation that can occur in clients with Alzheimer's disease. Aggression may result from frustration, confusion, fear, or other underlying factors. It can present challenges for both the individual with Alzheimer's and their caregivers.

C. Depression: Depression is a mood disorder that can occur in individuals with Alzheimer's disease. Symptoms of depression may include persistent sadness, feelings of hopelessness, social withdrawal, and loss of interest in previously enjoyed activities. Depression can exacerbate cognitive decline and functional impairment in individuals with Alzheimer's.

D. Hyperactivity: Hyperactivity, characterized by excessive or restless activity, can occur in some individuals with Alzheimer's disease. Hyperactivity may be a manifestation of agitation, anxiety, or other underlying factors. It can present challenges for caregivers and may require interventions to manage.

E. Lethargy: Lethargy, or extreme fatigue and lack of energy, can also occur in individuals with Alzheimer's disease. Lethargy may result from physical and cognitive decline, medication side effects, depression, or other medical conditions. It can contribute to decreased engagement in activities and worsening of cognitive function.
