A nurse is caring for a client in an adolescent unit. What is the nurse's priority when caring for a client with Asperger's disorder?

A. Early-stage dementia: At this stage, individuals might have some memory problems but can generally maintain independence. The symptoms described (significant memory loss, confusion, difficulty with language, and struggles with daily tasks) are more advanced than what is typically seen in early-stage dementia.

B. Mild cognitive impairment: This is a transitional stage between normal cognitive aging and dementia. It involves some memory problems and cognitive changes but not severe enough to impact daily functioning to the extent described.

C. Severe dementia: In this stage, individuals typically require assistance with most activities of daily living, have severe memory loss, and may not recognize close family members or understand their surroundings. The described symptoms do not yet indicate this level of severity.

D. Moderate dementia: This stage is characterized by more pronounced memory loss, confusion, difficulty with language, and an increasing need for help with daily tasks such as dressing and bathing, matching the client's symptoms.

A. "Donepezil (Aricept) encourages production of acetylcholine, a chemical in the brain necessary for memory processes. It delays the progression of the disease.": This statement is partially correct. Donepezil inhibits the breakdown of acetylcholine rather than encouraging its production. However, it correctly states that it delays the progression of Alzheimer's disease.

B. "Donepezil (Aricept) delays the destruction of dopamine, a chemical in the brain necessary for memory processes. Although most effective in the early stages, it serves to delay, but not stop, the progression of the disease.": This is incorrect because Alzheimer's disease primarily involves acetylcholine, not dopamine.

C. "Donepezil (Aricept) delays the destruction of acetylcholine, a chemical in the brain necessary for memory processes. Although most effective in the early stages, it serves to delay, but not stop, the progression of the disease.": This is the correct statement. Donepezil is a cholinesterase inhibitor that helps maintain acetylcholine levels in the brain, which is important for memory and cognitive function. It does not cure Alzheimer's disease but can slow its progression.

D. "Donepezil (Aricept) encourages production of dopamine, a chemical in the brain necessary for memory processes. It delays the progression of the disease.": This is incorrect because donepezil does not affect dopamine levels significantly in the context of Alzheimer's disease.
