ATI Nutrition Proctored Exam 2019 Answers

1. The type of protein-energy malnutrition that results in edema, hypoalbuminemia, skin lesions, and fatty liver is:

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. Which age group is particularly vulnerable to malnutrition?

Correct answer: A

Rationale: Infants are particularly vulnerable to malnutrition due to their high growth rate and specific nutrient requirements. During the first year of life, infants experience rapid growth and development, requiring essential nutrients for proper physical and cognitive development. Teenagers, young adults, and middle-aged adults have more stable nutritional needs compared to infants, making them less vulnerable to malnutrition. Therefore, infants are the most susceptible age group when it comes to malnutrition.

3. The lining of the stomach and intestine is protected from self-digestion by:

Correct answer: C

Rationale: The correct answer is C: mucus. Mucus forms a protective barrier that prevents the stomach and intestine from digesting themselves. Pepsinogen (choice A) is an inactive form of pepsin, a digestive enzyme, and does not protect the stomach lining. Bile (choice B) aids in the digestion and absorption of fats but does not protect the stomach lining. Fat (choice D) is a nutrient and energy source; it does not play a role in protecting the stomach and intestine from self-digestion.

4. What are the rhythmic contractions that propel food through the intestinal tract called?

Correct answer: B

Rationale: Peristalsis is the correct answer because it refers to the rhythmic contractions that propel food through the intestinal tract by pushing it along the digestive system. Segmentation, on the other hand, refers to the mixing movements in the intestines rather than the forward movement of food. Cardiospasm is a condition characterized by difficulty swallowing due to the inability of the esophagus to relax, and pendular movements are a type of motility found in the small intestine but do not specifically refer to the propulsion of food.

5. What is the main body storage form of carbohydrates?

Correct answer: A

Rationale: The correct answer is A: Glycogen. Glycogen is the stored form of carbohydrates in the body, primarily found in the liver and muscles. Starch (choice B) is a carbohydrate storage molecule in plants, not in the human body. Fat (choice C) is a different macronutrient and not the main storage form of carbohydrates. Glucose (choice D) is a simple sugar that serves as an energy source, not the main storage form of carbohydrates.
