ATI Nutrition Proctored Exam 2019 Answers

1. Most fat replacers are made from:

Correct answer: B

Rationale: Most fat replacers are made from carbohydrates. Carbohydrates are utilized to mimic the texture of fats in food products. Proteins (Choice A) are not commonly used as fat replacers and are more often associated with other functions in food. Cholesterol (Choice C) is a type of fat and not used to replace fat in food products. Monoglycerides (Choice D) are sometimes used as emulsifiers or stabilizers in food products but are not the primary source of fat replacers.

2. Amino acids that can be synthesized by the body in sufficient amounts are known as:

Correct answer: B

Rationale: The correct answer is B, 'dispensable.' Dispensable amino acids are those that the body can synthesize in sufficient amounts, so they are not required to be obtained from the diet. Indispensable amino acids, on the other hand, are essential and must be obtained from the diet because the body cannot produce them in sufficient quantities. Choices C and D, 'simple' and 'complex,' are incorrect as they do not accurately describe amino acids in terms of synthesis by the body.

3. How many kilocalories are provided by 15 grams of protein?

Correct answer: C

Rationale: Protein provides 4 kcal per gram. Therefore, 15 grams of protein will provide 15 grams x 4 kcal/gram = 60 kcal. Choices A, B, and D are incorrect because they do not consider the caloric value of protein correctly.

4. During the process of deamination, the nitrogen portion of amino acids is converted to:

Correct answer: A

Rationale: During the process of deamination, the nitrogen portion of amino acids is converted to ammonia. This occurs in the liver as part of the process to remove excess nitrogen from the body. Choice B, 'protein,' is incorrect as deamination breaks down amino acids rather than synthesizing proteins. Choice C, 'purines,' is incorrect as purines are a type of nitrogenous base found in DNA and RNA, not a product of deamination. Choice D, 'glycogen,' is incorrect as glycogen is a storage form of glucose and not a product of amino acid deamination.

5. The professional primarily responsible for the application of nutrition science in clinical practice settings is the:

Correct answer: D

Rationale: The correct answer is D: registered dietitian. A registered dietitian is a healthcare professional with specialized training in nutrition and dietetics, making them primarily responsible for applying nutrition science in clinical practice settings. Nurses (choice A) and physicians (choice B) may have some knowledge of nutrition, but a registered dietitian has specific expertise in this area. Public health nutritionists (choice C) typically focus on community nutrition and public health programs, rather than clinical practice settings.
