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.

Explanation
A. Family conflict: Family conflict can contribute to suicidal ideation, but the presence of an active psychiatric disorder is a more direct risk factor.
B. Homosexuality: Sexual orientation itself is not a risk factor for suicide, but discrimination and lack of acceptance related to sexual orientation can contribute to risk.
C. Availability of firearms: Access to firearms increases the lethality of suicide attempts but is not as significant as the presence of an active psychiatric disorder.
D. Active psychiatric disorder: This is the correct answer. Conditions such as depression, bipolar disorder, and substance use disorders significantly increase the risk of suicide in adolescents.
Correct Answer is ["B","C","E"]
Explanation
A. Stand directly in front of the client when talking. Standing directly in front of a client with a history of anger and aggression can be perceived as confrontational and may escalate the situation. It's better to stand at an angle and maintain an open posture to appear less threatening. Therefore, this choice is incorrect.
B. Avoid wearing necklaces during client care. Wearing necklaces or other loose jewelry can pose a safety risk if a client becomes aggressive and grabs them. Avoiding such items is a precaution to prevent potential harm. This choice is correct.
C. Provide immediate verbal feedback for escalating behavior. Providing immediate verbal feedback is important to de-escalate aggressive behavior by addressing it promptly and setting clear boundaries. This helps in managing the client's behavior effectively. This choice is correct.
D. Bring security with you for all client interactions. While bringing security can be necessary in certain high-risk situations, it is not appropriate or practical for all interactions and can increase the client's anxiety or aggression. Instead, security should be involved based on risk assessment and the specific context. Therefore, this choice is incorrect.
E. Review the layout of the facility. Knowing the layout of the facility is important for ensuring safety and planning escape routes if a situation becomes unsafe. It helps staff navigate the environment efficiently in case of an emergency. This choice is correct.
