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?

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. How are lipids carried in the bloodstream?

Correct answer: D

Rationale: Lipids are carried in the bloodstream in the form of lipoproteins. Lipoproteins are complexes of proteins and lipids that transport fats to various parts of the body. While micelles, glycolipids, and lecithin are all related to lipid metabolism, they are not the primary carriers of lipids in the bloodstream. Micelles are small lipid clusters in the intestines, glycolipids are lipids with a carbohydrate attached, and lecithin is a type of phospholipid. Therefore, lipoproteins are the correct answer as they are specifically designed for transporting lipids through the bloodstream.

3. Which compound is necessary for emulsification of fat in the body?

Correct answer: A

Rationale: Bile salts are essential for emulsifying fats in the body. They break down fats into smaller droplets, increasing the surface area for enzymes to work on during digestion. Cholecystokinin is a hormone that stimulates the release of bile and pancreatic enzymes, but it is not directly involved in emulsification. Chyme is the semi-fluid mass of partly digested food that moves from the stomach to the small intestine and does not play a role in emulsifying fats. Trypsin is an enzyme produced by the pancreas that acts on proteins, not fats.

4. Major nutrients supplied by foods in the Vegetables group of MyPlate include:

Correct answer: A

Rationale: The correct answer is A: potassium and vitamin A. Vegetables are an excellent source of potassium and vitamin A, both essential for maintaining overall health. Iron and vitamin C (choice B) are commonly found in foods from the Protein and Fruits groups, respectively. Calcium and vitamin B12 (choice C) are more abundant in dairy products and animal-based foods. Sodium and vitamin E (choice D) are not the major nutrients typically supplied by vegetables.

5. A chemical feature that distinguishes a saturated fatty acid from an unsaturated fatty acid is the:

Correct answer: C

Rationale: The correct answer is C. Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds. Therefore, the number of double bonds is the chemical feature that distinguishes a saturated fatty acid from an unsaturated fatty acid. Choices A, B, and D are incorrect because the distinguishing factor between saturated and unsaturated fatty acids lies in the presence or absence of double bonds, not in the arrangement of carbon atoms, number of oxygen molecules, or food source.
