A nurse is reinforcing teaching with an adolescent client who has a new diagnosis of lactose intolerance. Which of the following instructions should the nurse include in the teaching?

A. "You should gradually increase lactose products in your diet." For adolescents with lactose intolerance, gradually increasing lactose products may worsen symptoms. The goal is to reduce or avoid lactose-containing foods to prevent discomfort. B. "You should drink rice milk instead of cow's milk." Rice milk is lactose-free and can be a suitable alternative to cow's milk for someone with lactose intolerance. It is an appropriate recommendation for managing the condition. C. "You should limit your intake of calcium-fortified orange juice." Calcium-fortified orange juice is a good source of calcium, and it can be consumed without concern for lactose intolerance. It can help provide calcium, especially if dairy intake is limited. D. "You should eat flavored yogurt instead of plain yogurt." Flavored yogurt may contain added sugar and artificial ingredients, which are not necessarily better than plain yogurt. Plain yogurt can be easier to digest.
