ATI Nutrition Proctored Exam 2019 Answers
1. Infections are common in people who have inadequate protein intake because of an insufficient quantity of:
- A. insulin.
- B. lipoprotein.
- C. antibodies.
- D. albumin.
Correct answer: C
Rationale: Inadequate protein intake can lead to a decrease in antibody production, making individuals more susceptible to infections. Insulin (Choice A) is a hormone involved in regulating blood sugar levels, not related to protein intake. Lipoprotein (Choice B) is a type of lipid-protein complex involved in lipid transport, not directly related to antibody production. Albumin (Choice D) is a protein that helps maintain oncotic pressure and carries various substances in the blood, but it is not primarily responsible for fighting infections like antibodies.
2. An example of government nutrition policy is:
- A. MyPlate Food Guidance System.
- B. Dietary Guidelines for Americans 2010.
- C. Healthy People 2020.
- D. Dietary Reference Intakes (DRIs).
Correct answer: C
Rationale: The correct answer is C: Healthy People 2020. Healthy People 2020 is a government initiative that sets goals for improving the health of Americans, including specific nutritional objectives. Choices A, B, and D are not examples of government nutrition policies. MyPlate Food Guidance System is a visual tool to help individuals make healthy food choices, Dietary Guidelines for Americans 2010 provide evidence-based advice for Americans two years and older, and Dietary Reference Intakes (DRIs) are a set of nutrient reference values.
3. In the most recent edition of Choose Your Foods: Exchange List for Diabetes, the three groups into which foods are arranged are:
- A. fruits and vegetables, breads, and meats.
- B. fats, starches and sugars, and meat and milk.
- C. fruits and vegetables, meat and milk, and starches.
- D. carbohydrates, meat and meat substitutes, and fats.
Correct answer: D
Rationale: The correct answer is D: carbohydrates, meat and meat substitutes, and fats. The most recent edition of Choose Your Foods: Exchange List for Diabetes categorizes foods into these three groups for easier meal planning. Choice A is incorrect because it does not include carbohydrates and groups bread with fruits and vegetables. Choice B is incorrect because it separates carbohydrates into starches and sugars, which are usually counted together in diabetes meal planning. Choice C is incorrect as it does not specifically categorize foods into carbohydrates, meat, and fats as per the latest edition.

- A. 9
- B. 10
- C. 12

These amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices B, C, and D are incorrect as the number of essential amino acids is specifically 9, as they are crucial for various bodily functions.
5. How many different amino acids make up human proteins?
- A. 9
- B. 13
- C. 15
- D. 20
Correct answer: D
Rationale: The correct answer is D: 20. There are 20 different amino acids that combine to form proteins in the human body. Each amino acid has a unique side chain that determines its properties.
