A nurse is reviewing a client's medication list. Which medication has been indicated for improvement in cognitive functioning in mild to moderate Alzheimer's disease?

A. History of abuse: A history of physical, emotional, or sexual abuse is a significant risk factor for developing conduct disorder. Children who have experienced abuse may exhibit aggressive and defiant behaviours as a means of coping with their trauma.

B. Has more than three siblings: Having a large number of siblings alone is not directly associated with conduct disorder. Family dynamics and individual relationships are more relevant than the number of siblings.

C. A structured household environment: A structured household environment, typically characterized by consistent rules and supportive parenting, is generally protective against behavioural disorders like conduct disorder.

D. Diagnosis of many chronic medical illnesses: Chronic medical illnesses are not typically linked to conduct disorder. Risk factors for CD are more commonly related to psychosocial and environmental issues rather than medical conditions

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.
