A nursing instructor is teaching about donepezil (Aricept). A student asks, "How does this work? Will this cure Alzheimer's disease (AD)?" Which appropriate statement will the instructor make?
"Donepezil (Aricept) encourages production of acetylcholine, a chemical in the brain necessary for memory processes. It delays the progression of the disease."
"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."
"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."
"Donepezil (Aricept) encourages production of dopamine, a chemical in the brain necessary for memory processes. It delays the progression of the disease."
The Correct Answer is C
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.
