You have taken a new position as a home health nurse. One of your patients is an elderly woman who has a leg ulcer and a long history of diabetes. Your role is to assess the patient in relationship to her diabetic management and wound care and teach as needed. While you are in the home, her husband tells you that he has been having pain in his knee and asks if you would examine it and tell him whether it is all right to use a heating pad on it, and whether he should take ibuprofen or some Tylenol. Do you have a duty to help him? Why or why not? What will your response be? What legal issues are involved in this situation? If you advise him and your advice turns out to be incorrect, what legal action could he take?
