1. How would protein deficiency likely affect dental tissues?
- A. Decreased resistance to dental caries
- B. Increased tooth size
- C. Delayed tooth development
- D. Increased enamel mineralization
Correct answer: C
Rationale: Protein deficiency can lead to delayed tooth development as the body may not have enough resources to form teeth properly. This delay can make the teeth more susceptible to dental issues due to incomplete formation. Choices A, B, and D are incorrect. Decreased resistance to dental caries is more related to factors like poor oral hygiene and sugary diets, increased tooth size is not a common effect of protein deficiency on dental tissues, and increased enamel mineralization is not typically associated with protein deficiency.
2. Each statement is true of rickets, except one. Which is the exception?
- A. Rickets is being diagnosed more frequently in the United States.
- B. Rickets is caused by vitamin C deficiency.
- C. Tachetic deformities such as bow legs or knock-knees develop.
- D. A narrow and distorted chest occurs.
Correct answer: B
Rationale: Rickets is caused by vitamin D deficiency, not vitamin C deficiency. It usually occurs in children who are 1 to 3 years old. The name rickets came from the word 'wrikken,' meaning 'to bend or twist.' Common manifestations of rickets include tachetic deformities like bow legs or knock-knees, a narrow and distorted chest, and failure of the epiphyses of bones to develop normally, resulting in twisted and warped bones. While the diagnosis of rickets may be increasing in the United States, it is not caused by a lack of vitamin C.
3. 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.
4. Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.
- A. Both statements are true.
- B. Both statements are false.
- C. The first statement is true; the second is false.
- D. The first statement is false; the second is true.
Correct answer: C
Rationale: The first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.
5. For patients with anemia, which vitamin is crucial for the absorption of iron?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin E
Correct answer: B
Rationale: The correct answer is Vitamin C. Vitamin C enhances the absorption of non-heme iron, which is crucial for patients with anemia. Vitamin A (Choice A) is not directly involved in iron absorption. Vitamin D (Choice C) helps with calcium absorption, not iron. Vitamin E (Choice D) does not have a significant role in iron absorption.
