During a home visit, the nurse assesses a client with Alzheimer's Di’ease who recently started a new prescription for rivastigmine. The caregiver reports that the client seems to be thinking more clearly but is not sleeping well at night. Which action should the nurse take?

A) Instruct the caregiver to withhold the medication until the dosage can be decreased to ensure the client's sa’ety: Withholding the medication without consulting the healthcare provider may not be appropriate, especially if the client is experiencing improvements in cognitive function. The insomnia may be a temporary side effect that could resolve with continued use or adjustment of the dosage. B) Notify the healthcare provider that the dosage of the medication may need to be increased to manage the client's in’omnia: Increasing the dosage of rivastigmine to manage insomnia may not be the most appropriate action. It's es’ential to assess the client further and explore other interventions before considering a dosage adjustment. C) Advise the caregiver that the purpose of the medication is to promote sleep, so a change in medication may be needed: Rivastigmine is not typically used to promote sleep. It is a cholinesterase inhibitor used to treat cognitive symptoms associated with Alzheimer's di’ease. Therefore, advising a change in medication solely based on the client's in’omnia is not appropriate. D) Explain to the caregiver that insomnia is a common and temporary side effect when the medication is first started: Rivastigmine and other cholinesterase inhibitors may cause insomnia, especially when therapy is initiated. Educating the caregiver about this common side effect helps manage expectations and provides reassurance that the insomnia may improve over time as the client's bo’y adjusts to the medication.
