I'm working on a nursing multi-part question and need an explanation and answer to help me learn.

Question 1: Lester is a 67-year-old male who is prescribed Warfarin for his new onset atrial fibrillation. He is concerned about starting this medication and admits he is forgetful about taking meds and doesn’t understand why he has to have follow-up blood tests. Discuss the patient education you would offer about Warfarin (include side effects). How would you address his concerns and questions? How can you ensure your patient education information is accurate and up to date?

Question 2: Define dementia of Alzheimer type (DAT) and describe the pathophysiology, clinical manifestations, evaluation and treatment.
