The adverse effects of xanthene are related to the theophylline levels in the blood and include brain damage.
True.
False.
The Correct Answer is A
Choice A rationale
True. Xanthine derivatives like theophylline can cause serious adverse effects, including brain damage, when blood levels become too high. It is critical to monitor theophylline levels to prevent toxicity and associated neurological complications.
Choice B rationale
False. If xanthine levels remain within therapeutic ranges, the risk of brain damage is minimized. However, this statement is incorrect as it does not acknowledge the potential severity of the adverse effects linked to elevated theophylline levels.

Correct Answer is C
Explanation
Choice A rationale
Exhibiting the ability to provide self-care may not be realistic for a patient with advanced Alzheimer’s disease. Cognitive decline may impair their ability to perform daily activities independently, necessitating assistance from caregivers.
Choice B rationale
Improving memory for recent events is unlikely in advanced Alzheimer’s disease, as the condition typically involves progressive memory loss and cognitive decline. New medications may help manage symptoms, but reversing memory loss is not a realistic goal.
Choice C rationale
Receiving appropriate assistance for care needs is a realistic and achievable goal for patients with advanced Alzheimer’s disease. As the disease progresses, patients will require increasing levels of support to ensure their safety and well-being.
Choice D rationale
Demonstrating improved cognitive function is unlikely in advanced Alzheimer’s disease. While medications may help manage symptoms, the progressive nature of the disease means that cognitive decline will continue, and improvement is not a realistic expectation.
