A nurse is planning to teach an adolescent who is lactose intolerant about dietary guidelines. Which of the following instructions should the nurse include in the teaching?

A. “You might tolerate plain milk better than chocolate milk.”: Both plain and chocolate milk contain lactose, and intolerance is related to lactose content rather than added flavoring. Changing the type of milk does not reliably reduce gastrointestinal symptoms associated with lactose intolerance. B. “You can drink milk on an empty stomach”: Consuming milk on an empty stomach often worsens symptoms because lactose is rapidly delivered to the intestine without other foods to slow digestion. This can increase bloating, cramping, and diarrhea in individuals with lactose intolerance. C. “You can replace milk with nondairy sources of calcium”: Nondairy calcium sources such as fortified soy or almond milk, leafy green vegetables, and calcium-fortified cereals help meet nutritional needs without causing symptoms. This approach supports bone health while avoiding lactose exposure. D. “You should consume generous amounts of plain yogurt.”: Although yogurt may be better tolerated due to bacterial lactase, consuming generous amounts can still trigger symptoms in some adolescents. Tolerance varies, so recommending large quantities is not appropriate as a general guideline.
