ATI Nutrition Proctored Exam 2019 Answers
1. The type of protein-energy malnutrition that results in edema, hypoalbuminemia, skin lesions, and fatty liver is:
- A. cachexia.
- B. marasmus.
- C. kwashiorkor.
- D. sarcopenia.
Correct answer: C
Rationale: The correct answer is C, kwashiorkor. Kwashiorkor is a type of protein-energy malnutrition characterized by edema, hypoalbuminemia, skin lesions, and fatty liver. Edema is a key feature of kwashiorkor due to hypoalbuminemia, which leads to decreased oncotic pressure. Marasmus (choice B) is a form of severe malnutrition characterized by energy deficiency without significant protein deficiency, resulting in severe wasting. Cachexia (choice A) is a syndrome characterized by weight loss, muscle atrophy, fatigue, weakness, and loss of appetite in someone who is not actively trying to lose weight. Sarcopenia (choice D) is the age-related loss of muscle mass and function.
2. Most fat replacers are made from:
- A. proteins.
- B. carbohydrates.
- C. cholesterol.
- D. monoglycerides.
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.
3. Plasma lipoproteins contain varying amounts of:
- A. ascorbic acid.
- B. triglycerides.
- C. lecithin.
- D. glucose.
Correct answer: B
Rationale: The correct answer is B: triglycerides. Plasma lipoproteins, such as LDL and HDL, contain triglycerides, cholesterol, and other fats. Ascorbic acid (choice A) is not typically found in plasma lipoproteins; it is a form of vitamin C. Lecithin (choice C) is a phospholipid found in cell membranes but is not a major component of plasma lipoproteins. Glucose (choice D) is a type of sugar and is not a primary component of plasma lipoproteins.
4. Which of the following monosaccharides is considered one of the most important in human nutrition along with glucose and fructose?
- A. Lactose.
- B. Galactose.
- C. Maltose.
- D. Sucrose.
Correct answer: B
Rationale: The most important monosaccharides in human nutrition are glucose, fructose, and galactose. Galactose is crucial as it is one of the main components of lactose, a disaccharide sugar found in milk. Therefore, choices A, C, and D are incorrect as lactose, maltose, and sucrose are disaccharides composed of two monosaccharide units.
5. Where is Vitamin B12 found?
- A. Whole grains.
- B. Nuts.
- C. Meats.
- D. Legumes.
Correct answer: C
Rationale: Vitamin B12 is primarily found in animal-derived foods like meats. Choices A, B, and D are incorrect as whole grains, nuts, and legumes do not naturally contain significant amounts of Vitamin B12. Therefore, the correct answer is 'C: Meats.'
