Final answer:
The nurse should explain that eating alone may not meet all of the client's nutritional needs, and that TPN is a temporary measure.
Step-by-step explanation:
The nurse should respond with option B) "Eating alone may not meet all of your nutritional needs right now."
TPN stands for Total Parenteral Nutrition, which is a method of providing nutrition directly into the bloodstream when the digestive system is unable to absorb nutrients. While the client is able to eat, TPN may still be necessary to ensure that all nutritional needs are being met.
It is important for the nurse to explain to the client that TPN is a temporary measure, and they will be able to stop it once their oral intake is sufficient to meet their nutritional needs.
