1. Clients with type 2 diabetes are most likely to achieve metabolic control if they:
- A. lose weight
- B. use self-monitoring of blood glucose
- C. eliminate all dietary sugars
- D. eat three regular meals daily
Correct answer: A

2. _____ neutralizes stomach acid in the small intestine:
- A. saliva
- B. gastric mucus
- C. bicarbonate ions
- D. enzymes
Correct answer: C
Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.
3. A nurse is caring for a 30-month-old toddler and is preparing a nutritional snack. Which of the following foods is appropriate for the nurse to offer the toddler?
- A. Plain popcorn
- B. Grapes
- C. Raw carrots
- D. Cheese
Correct answer: D
Rationale: Cheese is a safe and nutritious option for toddlers as it provides calcium and protein without posing choking hazards. Plain popcorn, grapes, and raw carrots are not recommended for toddlers due to the potential choking risks they present, especially at a young age.
4. What is the function of villi and microvilli in the GI tract?
- A. produce bile
- B. kill bacteria
- C. produce vitamin K
- D. increase the surface area for absorption
Correct answer: D
Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.
5. Match the energy-yielding nutrient to the amount of energy it provides to the body: Carbs, Fats, Proteins.
- A. Carbs - 4kcal/g
- B. Fats - 9kcal/g
- C. Proteins - 4kcal/g
- D. All of the above
Correct answer: D
Rationale: The correct answer is D, All of the above. Carbohydrates and proteins provide 4 kcal per gram, while fats provide 9 kcal per gram. Therefore, all three energy-yielding nutrients provide different amounts of energy to the body. Choice A, B, and C are incorrect because each of them individually provides a specific amount of energy per gram, but when considering all nutrients together, they collectively cover the spectrum of energy provision to the body.
