The nurse is providing instructions about a client's new medications. How should the nurse explain the purpose of probenecid, a uricosuric drug?

Choice A reason: Baclofen is a muscle relaxant that can cause drowsiness, dizziness, and orthostatic hypotension. These side effects can increase the risk of falls and injuries for the client. Therefore, the nurse should advise the client to move slowly and cautiously when rising and walking, and to use assistive devices if needed.

Choice B reason: Evaluating muscle strength every 4 hours is not the most important intervention for the nurse to implement, as baclofen does not affect muscle strength directly. It may reduce muscle spasticity and stiffness, but it does not improve muscle function or coordination.

Choice C reason: Monitoring intake and output every 8 hours is not the most important intervention for the nurse to implement, as baclofen does not have a significant effect on fluid balance or renal function. However, the nurse should monitor the client for signs of urinary retention, which is a rare but possible adverse effect of baclofen.

Choice D reason: Ensuring the client knows to stop baclofen before using other antispasmodics is not the most important intervention for the nurse to implement, as baclofen can be used in combination with other antispasmodics under medical supervision. However, the nurse should educate the client about the potential drug interactions and contraindications of baclofen, and to consult the prescriber before taking any new medications.

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.
