1. _____ 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.
2. A pregnant woman has applied to use WIC services to supplement her food intake. The WIC program would provide vouchers for _____ in this situation.
- A. lean beef
- B. fruit-flavored yogurt
- C. whole grain bread
- D. refried beans
Correct answer: C
Rationale: The correct answer is C: whole grain bread. The WIC program aims to provide nutritious foods to support a healthy diet during pregnancy. Whole grain bread is a good source of fiber and essential nutrients. Choice A, lean beef, is a protein source but may not be as versatile as whole grain bread in providing a variety of nutrients essential during pregnancy. Choice B, fruit-flavored yogurt, may contain added sugars and may not offer the same level of essential nutrients as whole grain bread. Choice D, refried beans, is a good source of protein and fiber, but whole grain bread is often a staple recommended in pregnancy for its nutritional benefits.
3. Which food item should be recommended to prevent choking in toddlers?
- A. Banana slices
- B. Popcorn
- C. Hot dogs
- D. Carrot sticks
Correct answer: A
Rationale: Banana slices are less likely to cause choking compared to other options.
4. Which of the following statements is false?
- A. People with a vitamin K deficiency experience increased clotting time
- B. The major function of vitamin E is promoting vision
- C. Vitamin D functions as a hormone
- D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash
Correct answer: B
Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.
5. Characteristics of type two diabetes include all of the following except:
- A. insulin resistance
- B. blood glucose levels that rise too high
- C. blood insulin levels that rise too high
- D. rapid destruction of the pancreas
Correct answer: D
Rationale: Type 2 diabetes is characterized by insulin resistance, high blood glucose levels, and high blood insulin levels. Rapid destruction of the pancreas is not a feature of this condition. The destruction of pancreatic beta cells is more commonly associated with type 1 diabetes, not type 2 diabetes. Therefore, option D is the correct answer. Options A, B, and C are all characteristic features of type 2 diabetes, making them incorrect choices.
