ATI Nutrition Proctored Exam 2019 Answers
1. Which of the following foods is high in indispensable amino acids?
- A. Lentils
- B. Tofu
- C. Peanuts
- D. Eggs
Correct answer: D
Rationale: The correct answer is D, eggs. Eggs are considered a high-quality protein source as they are rich in indispensable amino acids. Lentils, tofu, and peanuts also contain protein but are not as high in indispensable amino acids as eggs, making them less complete protein sources.
2. Which hormone is responsible for stimulating the gallbladder to contract and release bile?
- A. gastric lipase
- B. cholecystokinin
- C. vitamin D
- D. enterokinin
Correct answer: B
Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone responsible for stimulating the gallbladder to contract and release bile to aid in fat digestion. Gastric lipase (Choice A) is an enzyme that breaks down fats in the stomach, not a hormone involved in gallbladder function. Vitamin D (Choice C) is important for calcium absorption and bone health, but it is not directly related to gallbladder function. Enterokinin (Choice D) is a peptide hormone that affects smooth muscle contractions in the gastrointestinal tract, but it is not specifically responsible for stimulating the gallbladder to release bile.
3. What is the preferred fuel for the cells lining the colon?
- A. Short-chain fatty acids.
- B. Long-chain fatty acids.
- C. Amino acids.
- D. Glucose.
Correct answer: A
Rationale: Short-chain fatty acids are the preferred fuel for the cells lining the colon. They provide energy and support gut health by serving as a fuel source for these cells. Long-chain fatty acids are not the preferred fuel for colon cells as they are harder to digest and absorb in this part of the digestive system. Amino acids are the building blocks of proteins and not the primary energy source for colon cells. Glucose is the main energy source for most cells in the body, but colon cells prefer short-chain fatty acids.
4. A food choice equivalent to one serving from the Grains group of MyPlate is:
- A. one slice of bread
- B. 2 cups of rice
- C. 3 cups of spaghetti
- D. 4 oz of ready-to-eat cereal
Correct answer: A
Rationale: One slice of bread is a standard serving from the Grains group in MyPlate. This choice aligns with the recommended portion size for grains. Choices B, C, and D are excessive portions that do not represent a single serving according to MyPlate guidelines. 2 cups of rice, 3 cups of spaghetti, and 4 oz of ready-to-eat cereal exceed the standard serving size for grains and would provide more than one serving from this food group.
5. Which of the following foods are major sources of starch?
- A. Fruits
- B. Meats
- C. Legumes
- D. Milk
Correct answer: C
Rationale: The correct answer is C: Legumes. Legumes, such as beans and lentils, are major sources of starch, providing complex carbohydrates. Fruits (choice A) mainly provide sugars rather than starch. Meats (choice B) and milk (choice D) are not significant sources of starch as they mainly provide protein and fats, respectively. Therefore, choices A, B, and D are incorrect.
