The adult child of an older adult client who has Parkinson's disease, calls the clinic and reports that the client has been confused for the past week. What action(s) should the nurse take? Select all that apply.

A. Falls can lead to head injuries or subdural hematomas, which can cause confusion in older adults. It is important to assess for recent trauma as a possible cause of the confusion. B. An elevated temperature can indicate an infection, such as a urinary tract infection (UTI) or pneumonia, which are common causes of acute confusion in older adults. C. Pain with urination is a symptom of a UTI, which can lead to confusion, especially in elderly patients with Parkinson's disease. D. While maintaining adequate nutrition is important, increasing protein intake does not directly address the sudden onset of confusion. E. New medications or allergic reactions can lead to confusion. A medication interaction or an allergic reaction to a new food could be a contributing factor.
