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.

Correct Answer is ["A","B","E"]
Explanation
A. Necklace: This can be a strangulation risk and should be removed from the client’s belongings.
B. Lace-up tennis shoes: The laces can be used for self-harm or strangulation and should be removed.
C. Nylon ankle socks: These are generally safe and do not pose a risk.
D. Cotton underwear: This is also considered safe and does not pose a significant risk.
E. Glass framed picture of the client's partner: The glass can be broken and used for self-harm, making it unsafe for a client with recent suicidal behavior.
Correct Answer is D
Explanation
. Use physical restraints during severe outbursts to ensure safety. Physical restraints are not appropriate for managing behavioural issues in children with ODD. They can escalate the situation, cause physical harm, and damage the trust between the child and caregivers.
B. Assign daily chores that are challenging to encourage discipline. While chores can teach responsibility, assigning challenging tasks is not appropriate for managing ODD and could lead to frustration and further defiance.
C. Encourage solitary play to reduce social stressors. Solitary play might reduce social stress but does not address the underlying behavioural issues of ODD. Social skills and interactions need to be improved rather than avoided.
D. Put into practice consistent consequences for rule-breaking behaviour. Consistent consequences help the child understand the link between behaviour and outcomes, which is crucial for managing ODD. It provides structure and clear expectations, which are essential for children with behavioral issues.
