Rivastigmine, a cholinesterase inhibitor, is prescribed for a female client with early stage Alzheimer's disease. The client's daughter tells the nurse that she plans to start administering the drug when her mother's symptoms are no longer manageable, in hopes that her mother will not have to go to a nursing home. How should the nurse respond?

Choice A reason: Confirming that the daughter is aware of the progressive nature of the disease is not the best response, as it does not address the daughter's misconception about the drug. The nurse should educate the daughter that rivastigmine does not cure or stop the progression of Alzheimer's disease, but only slows down the cognitive decline.Choice B reason: Affirming the decision to use the medication when the symptoms start to worsen is not appropriate, as it contradicts the evidence-based practice. The nurse should inform the daughter that rivastigmine is most effective when used in the early stages of Alzheimer's disease, as it can delay the need for institutionalization and improve the quality of life.Choice C reason: Explaining that the drug should be used early in the course of the disease process is the best response, as it corrects the daughter's misunderstanding and provides accurate information. The nurse should explain that rivastigmine works by inhibiting the enzyme that breaks down acetylcholine, a neurotransmitter that is involved in memory and learning. By increasing the level of acetylcholine in the brain, rivastigmine can improve the cognitive function and behavior of the client.Choice D reason: Assessing the client's current mental status before deciding to support the decision is not relevant, as it does not address the daughter's concern or the rationale for the drug. The nurse should already have the client's baseline mental status from the initial assessment and diagnosis. The nurse should focus on educating the daughter about the benefits and risks of rivastigmine and encouraging her to follow the prescribed regimen.
