Answer to Question 1

B
Antioxidants are substances such as vitamins C and E, beta-carotene, and selenium, which prevent or inhibit oxidation; they prevent tissue damage related to free radicals, which are unstable molecules that alter genetic codes and can trigger cancer cell growth. Free radicals are also associated with cardiovascular disease.

Answer to Question 2

D
Phytochemicals are nonnutritive, physiologically active compounds present in small amounts in plants. They store nutrients and provide structure, aroma, flavor, and color. Phytochemicals are found in fruits such as cantaloupe, oranges and other citruses, grapes, strawberries, raspberries, and cherries, and in vegetables such as onions, garlic, carrots, sweet potatoes, squash, and pumpkin; they can protect people from cancer and prevent heart disease, stroke, and cataracts. Because no single fruit or vegetable contains all phytochemicals, it is important for nurses to encourage clients to eat a wide variety of fruits and vegetables daily.
