Answer to Question 1

Ans: B
Sundown syndrome may be caused by a misinterpretation of the environment, lower tolerance for stress at the end of the day, or overstimulation due to increased environmental activity later in the day. Clients may exhibit altered sleep patterns, such as sleeping throughout the day. Agnosia is the failure to recognize or identify objects despite intact sensory function. Confabulation is the filling in of memory gaps with false but sometimes plausible content to conceal the memory deficit. Preservation is the inappropriate continuation or repetition of a behavior.

Answer to Question 2

Ans: C
The predominate finding of bilateral posterior temporal and parietal perfusion defects is thought to be highly predictive of DAT. Parkinson's disease is due to the presence of neurohistologic lesions in the basal ganglia. Binswanger's disease is a type of vascular dementia that is characterized by the presence of many small infarctions affecting the white matter of the brain. Vascular dementia is thought to result from infraction of small- and medium-sized vessels causing parenchymal lesions to occur over wide areas of the brain.
