A) A patient's risk of developing delirium is directly related to his or her coping ability.
B) Delirium must be differentiated from dementia because the two disorders do not coexist.
C) Inpatient treatment is often the trigger that initiates an individual's dementia.
D) A majority of elderly patients experience some form of delirium during inpatient treatment.
Ans: D
Feedback:
Delirium is the most common psychiatric syndrome in general hospitals, occurring in as many as 54% of elderly inpatients. Individuals with dementia are not immune to delirium and neither problem is related to inadequate coping. Dementia is not caused by stressors such as hospital treatment, though such circumstances may exacerbate symptoms of preexisting dementia.
