ATI Nutrition Proctored Exam
1. Which set of guidelines is intended to assess nutrient adequacy or plan intakes of population groups, not individuals?
- A. Old Recommended Dietary Allowances (RDA)
- B. Estimated Average Requirement (EAR)
- C. New Recommended Dietary Allowances (RDA)
- D. Tolerable Upper Intake Level (UL)
Correct answer: B
Rationale: The Estimated Average Requirement (EAR) is specifically designed to assess nutrient adequacy or plan intakes for population groups, not for individuals. The Old and New Recommended Dietary Allowances (RDA) are meant for individuals, not groups, as they provide guidelines for specific nutrient intake levels for healthy individuals. The Tolerable Upper Intake Level (UL) is used to set the highest level of nutrient intake that is likely to pose no risk of adverse health effects for most individuals in a group, which is different from assessing nutrient adequacy for groups.
2. Is it a good idea for an athlete to eliminate all fat from his diet in order to stay lean?
- A. yes, because dietary fat is stored easily in fat cells and can't be used for energy
- B. no, because fats provide energy during prolonged exercise
- C. yes, because fat is stored under the skin and causes the body to overheat
- D. no, because excess fat is converted to glycogen and stored in the muscles
Correct answer: B
Rationale: Fat is an essential energy source during prolonged exercise, so eliminating it entirely from the diet is not advisable for athletes.
3. Toilet training occurs in the anal stage of Freud’s psychosexual development. This is equivalent to Erikson’s:
- A. Trust vs. Mistrust
- B. Autonomy vs. Shame and Doubt
- C. Initiative vs. Guilt
- D. Industry vs. Inferiority
Correct answer: A
Rationale: The correct answer is A: Trust vs. Mistrust. In Freud's psychosexual development theory, the anal stage is where toilet training occurs, focusing on issues of control and independence. This stage is parallel to Erikson's Trust vs. Mistrust stage, where infants learn to trust or mistrust their caregivers based on the consistency of care they receive. Choices B, C, and D are incorrect as they correspond to different stages in Erikson's psychosocial development theory, not related to toilet training or the anal stage of Freud's theory.
4. Who most often prescribes a patient's diet order?
- A. Registered Nurse
- B. Physician
- C. Registered Dietetic Technician
- D. Occupational Therapist
Correct answer: B
Rationale: A patient's dietary order is most frequently prescribed by a physician. This is because the physician has a comprehensive understanding of the patient's medical condition and can thus determine the most suitable dietary plan. Registered dietitians often collaborate with physicians in this process, but the final prescription is made by the physician. Although registered nurses, dietetic technicians, and occupational therapists play significant roles in patient care, they typically do not prescribe diet orders.
5. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?
- A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
- B. Viscous fiber binds with bile in the intestine and is excreted in feces
- C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
- D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol
Correct answer: B
Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.
