ATI Nutrition Proctored Exam 2019 Answers
1. Which of the following is an example of a complete protein?
- A. Milk
- B. Soy
- C. Sesame seeds
- D. Sweet potato
Correct answer: A
Rationale: The correct answer is A, Milk. Milk is considered a complete protein as it contains all the essential amino acids required by the body. Soy (choice B) is also a complete protein, containing all essential amino acids. Sesame seeds (choice C) and sweet potato (choice D) are not complete proteins as they lack one or more essential amino acids needed by the body.
2. The major focus of nutritional recommendations in this century has shifted to:
- A. prevention and control of chronic diseases.
- B. improved sanitation and public health.
- C. prevention and control of infectious diseases.
- D. development of healthful foods using food technology.
Correct answer: A
Rationale: The correct answer is A: prevention and control of chronic diseases. In this century, nutritional recommendations have increasingly emphasized the importance of preventing and managing chronic diseases like obesity, diabetes, cardiovascular diseases, and cancer. Lifestyle factors such as diet play a significant role in the development of these conditions. Option B, improved sanitation and public health, although important for overall health, is not the primary focus of nutritional recommendations. Option C, prevention and control of infectious diseases, is also crucial but does not reflect the current major focus of nutritional recommendations. Option D, development of healthful foods using food technology, is a valid area of interest but is not the primary shift in focus observed in nutritional recommendations.
3. Amino acids that can be synthesized by the body in sufficient amounts are known as:
- A. indispensable.
- B. dispensable.
- C. simple.
- D. complex.
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.
4. Major nutrients supplied by foods in the Vegetables group of MyPlate include:
- A. potassium and vitamin A.
- B. iron and vitamin C.
- C. calcium and vitamin B12.
- D. sodium and vitamin E.
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. Where does gluconeogenesis occur?
- A. Muscles.
- B. Pancreas.
- C. Liver.
- D. Spleen.
Correct answer: C
Rationale: Gluconeogenesis mainly occurs in the liver. It is a process where glucose is synthesized from non-carbohydrate sources such as amino acids and glycerol. The liver is the primary site for gluconeogenesis due to the presence of key enzymes and substrates required for this process. Muscles do not play a significant role in gluconeogenesis, making choice A incorrect. The pancreas is involved in the regulation of blood sugar levels through insulin and glucagon but is not the primary site for gluconeogenesis, so choice B is incorrect. The spleen is not a major organ involved in glucose metabolism, making choice D incorrect.
