4. A nurse is completing an admission assessment on an adolescent client who is a vegetarian. He eats milk products but does not like beans. Which of the following items should the nurse suggest the client order for lunch to provide the nutrients most likely to be lacking in his diet?

• A. Peanut butter and jelly sandwich
• B. Baked potato topped with sour cream
• C. Bagel with cream cheese
• D. Fruit salad

Correct answer: D

Rationale: The correct answer is 'Fruit salad.' Since the adolescent client is a vegetarian who eats milk products but does not like beans, suggesting a fruit salad for lunch would provide essential nutrients like vitamins, minerals, and fiber that are commonly found in fruits. Fruit salad can help supplement the nutrients that may be lacking in his diet. Choices A, B, and C do not offer the same variety and quantity of nutrients as a fruit salad, making them less optimal choices for meeting the client's dietary needs.

The alimentary canal is involved in the digestive process and includes structures like the oral cavity (mouth), pharynx, and esophagus. Choices A, B, and D are parts of the alimentary canal, where digestion occurs, making them incorrect answers.
