The nurse is assessing a client with a new diagnosis of Listeria food poisoning. What action should the nurse take first?
Correct Answer: D
Rationale: The correct first action for the nurse to take when assessing a client with a new diagnosis of Listeria food poisoning is to inquire if the client has consumed any unpasteurized products. This is crucial because Listeria contamination is often associated with unpasteurized dairy products and undercooked meats. Educating the client on safe food practices (Choice A) is important but not the priority at this initial assessment stage. Starting a traceback to identify the source of the outbreak (Choice B) and reporting the case to the county board of health (Choice C) are necessary actions but should come after gathering information directly from the client regarding potential exposure to high-risk foods.
