Final answer:
The nurse should include that impairments in daily functioning are evident at stage 2 Alzheimer's disease, and emphasize that while treatments may slow progression, cognitive decline is not reversible.
Step-by-step explanation:
When educating the family of a client with stage 2 Alzheimer's disease (AD), it is important to note that impairments in daily functioning are evident at this stage of the condition.
At this moderate stage of AD, individuals experience disruptive memory loss, difficulties with language, and significant cognitive deficits which may lead to not recognizing family members, wandering, inappropriate behaviors, agitation, and challenges in carrying out daily activities such as dressing.
It is also important to understand that, currently, the cognitive decline associated with Alzheimer's disease is not reversible, and while there are treatments that may slow its progression, such as cholinesterase inhibitors, they do not restore lost memories or cognitive function.
