The daughter of an older woman who has Parkinson's disease, calls the clinic and reports that her mother has been confused for the past week. Which action(s) should the nurse take? (Select all that apply.)

A. Confusion can be a sign of a concussion or other injury resulting from a fall, which is a common risk for individuals with Parkinson's disease. B. Reviewing the client's current food and medication allergies is important as allergies can contribute to confusion if the client is exposed to an allergen. C. Encouraging increased intake of high protein foods is generally recommended for individuals with Parkinson's disease, but it is not directly related to the acute onset of confusion. D. Checking the mother's temperature is a direct action to assess for infection, which can be a cause of acute confusion, especially in older adults. E. Pain with urination could indicate a urinary tract infection, which is another common cause of confusion in the elderly. It is important to assess for this possibility.
