1. A vegan patient might be at risk for deficiency in which of the following nutrients?
- A. Vitamin B12
- B. Vitamin C
- C. Carbohydrates
- D. Fiber
Correct answer: A
Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.
2. In the following ingredient list, which is the most abundant by weight? Ingredients: enriched flour, sugars, eggs, soy lecithin, artificial colors, natural flavors, milk.
- A. milk
- B. eggs
- C. sugar
- D. enriched flour
Correct answer: D
Rationale: The correct answer is 'enriched flour.' In ingredient lists, items are typically listed by weight in descending order. Therefore, the first ingredient, in this case, 'enriched flour,' is the most abundant by weight. Choice A, 'milk,' is not the most abundant as it appears last in the list. Choice B, 'eggs,' and choice C, 'sugar,' also rank lower in the list compared to 'enriched flour,' making them less abundant by weight.
3. What best describes a task of the registered dietitian?
- A. administering total parenteral nutrition
- B. administering formula through feeding tubes
- C. prescribing diet orders
- D. conducting nutrition assessments
Correct answer: D
Rationale: The correct answer is D, conducting nutrition assessments. Registered dietitians are responsible for assessing an individual's nutritional status, dietary intake, and health needs. This assessment forms the basis for developing personalized nutrition care plans. Choices A and B involve the administration of specialized nutrition support, which is typically done by healthcare providers with specific training in those areas. Choice C, prescribing diet orders, may fall outside the scope of practice for a dietitian as they focus more on assessment, education, and counseling related to nutrition rather than prescribing medical treatments.
4. 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.
5. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?
- A. hemoglobin
- B. transferrin
- C. myoglobin
- D. hepcidin
Correct answer: A
Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.
