ATI Nutrition Proctored Exam 2023
1. Which of the following statements are true about iron?
- A. The iron needs of vegans are 20% higher, and the needs of endurance athletes are 10% lower.
- B. It is one of the most common nutrient deficiencies in the world.
- C. Its absorption is increased by Vitamin C and during pregnancy.
- D. Its absorption is increased by tannic acid and calcium in milk.
Correct answer: C
Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.
2. What is the primary purpose of dietary fiber in the diet?
- A. Improving digestion
- B. Providing energy
- C. Aiding in the absorption of vitamins
- D. Reducing cholesterol
Correct answer: D
Rationale: The primary purpose of dietary fiber in the diet is to reduce cholesterol levels. While it does aid in digestion by promoting regular bowel movements, its main role is in lowering cholesterol. Choice A is partially correct but not the primary purpose. Choice B is incorrect as fiber is not a direct source of energy. Choice C is also incorrect as the primary role of fiber is not in the absorption of vitamins.
3. What chronic disease has been associated with increased risks of dental problems?
- A. diabetes mellitus
- B. chronic obstructive pulmonary disease
- C. Addison's disease
- D. asthma
Correct answer: A
Rationale: Diabetes mellitus is associated with an increased risk of dental problems, including gum disease and tooth loss, due to high blood sugar levels. While chronic obstructive pulmonary disease (COPD), Addison's disease, and asthma may have oral health implications, diabetes mellitus is specifically known for its strong association with dental issues.
4. Which type of assessment evaluates a person's risk of malnutrition by ranking key variables from the medical history and physical examination?
- A. Katz index
- B. integrated assessment
- C. subjective global assessment
- D. nutrition care plan
Correct answer: C
Rationale: The Subjective Global Assessment (SGA) is the correct choice. SGA is a comprehensive tool used to assess an individual's risk of malnutrition by integrating key variables from the medical history, physical examination, and other relevant factors. The Katz index is used to assess activities of daily living, not malnutrition risk. An integrated assessment refers to the overall evaluation process involving multiple assessments. A nutrition care plan is a personalized plan developed based on assessment findings, not the assessment itself.
5. Cancers that arise from epithelial tissues are known as:
- A. Leukemias
- B. Myelomas
- C. Carcinomas
- D. Sarcomas
Correct answer: C
Rationale: The correct answer is C: Carcinomas. Carcinomas are cancers that originate from epithelial tissues, which are the tissues lining the surfaces of organs and structures in the body. Leukemias (choice A) are cancers of the blood-forming cells, not epithelial tissues. Myelomas (choice B) are cancers that develop in plasma cells in the bone marrow, not epithelial tissues. Sarcomas (choice D) are cancers that arise from connective tissues like bone, cartilage, or muscle, not epithelial tissues. Therefore, choices A, B, and D are incorrect in the context of cancers originating from epithelial tissues.
