ATI Nutrition Proctored Exam 2019 Answers
1. To prevent symptoms of fatigue, dehydration, and energy loss, what is the daily recommended minimum intake of carbohydrates?
- A. 130 g.
- B. 230 g.
- C. 330 g.
- D. 430 g.
Correct answer: A
Rationale: The correct answer is A: 130 g. The recommended minimum intake of carbohydrates to prevent fatigue, dehydration, and energy loss is 130 grams per day. Consuming an adequate amount of carbohydrates provides the body with energy and helps prevent symptoms associated with insufficient carbohydrate intake. Choices B, C, and D are incorrect as they suggest higher amounts of carbohydrate intake, which may not necessarily align with the recommended daily minimum intake for preventing symptoms of fatigue, dehydration, and energy loss.
2. What is the chemical structure that forms the base component of an amino acid?
- A. carboxyl group
- B. carbon chain
- C. radicals
- D. amino group
Correct answer: D
Rationale: The correct answer is the amino group. Amino acids consist of an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and a variable side chain attached to a central carbon atom. The amino group is essential for the formation of proteins. The carboxyl group is not the base component but another important functional group in amino acids. Carbon chain and radicals are not specific chemical structures that form the base component of an amino acid.
3. 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.
4. What is a major function of glucose?
- A. Produce energy.
- B. Transport oxygen to cells.
- C. Convert fat to glycogen.
- D. Maintain body weight.
Correct answer: A
Rationale: Glucose serves as a primary source of energy for the body, especially for the brain and muscles. Choice B is incorrect because glucose itself is not responsible for transporting oxygen to cells. Choice C is incorrect as glucose is converted to glycogen, not the other way around. Choice D is incorrect as glucose itself does not play a direct role in maintaining body weight.
5. Which mineral helps strengthen tooth enamel and prevent dental caries?
- A. Calcium
- B. Phosphorus
- C. Fluoride
- D. Zinc
Correct answer: C
Rationale: The correct answer is C, Fluoride. Fluoride is a mineral known for its ability to strengthen tooth enamel and prevent dental caries. While calcium (Choice A) is essential for strong bones and teeth, it is not specifically known for preventing dental caries. Phosphorus (Choice B) is crucial for bone health but is not directly associated with preventing dental caries. Zinc (Choice D) is not typically recognized for strengthening tooth enamel or preventing dental caries.
