A Incorrect. These qualities are characteristic of Lewy body dementia.
B Incorrect. These qualities are characteristic of Parkinson's disease dementia.
C Incorrect. These qualities are characteristic of frontotemporal lobe dementia.
D Correct. The nurse assesses the patient for failing memory and incoordination characteristic of Creutzfeldt-Jakob disease (CJD) or bovine spongiform ence-phalopathy (also known as mad cow disease). This type of dementia began ap-pearing in adults living in the British Isles who reported eating beef from local breeders. The nurse assesses for these qualities because the age of onset is usually 60 years. This form of dementia progresses rapidly to death, so the nurse anticipates that this man will deteriorate rapidly and must be prepared to antic-ipate changes in motor activities and memory to maintain his safety and prevent injury.
Answer to Question 2
B, C
Medication therapy is complicated and must be closely supervised. Hypotension, dyskinesias (involuntary movements), dystonia (lack of control of movement), hallucinations, sleep disorders, and depression are common side effects of both the disease and the medications used to treat it. Nausea is not a side effect of PD.
