ATI Nutrition Proctored Exam 2019 Answers
1. Where does the major portion of the chemical digestion of lipids occur?
- A. Mouth.
- B. Stomach.
- C. Small intestine.
- D. Large intestine.
Correct answer: C
Rationale: The correct answer is C: Small intestine. The majority of lipid digestion occurs in the small intestine, where bile and pancreatic lipase are active. Lipids are broken down into fatty acids and glycerol in the small intestine. Choices A, B, and D are incorrect because the mouth and stomach play minor roles in lipid digestion, and the large intestine is mainly responsible for absorbing water and electrolytes from the indigestible food residues.
2. A physical science that contributes to understanding how nutrition relates to health and well-being is:
- A. anatomy
- B. biochemistry
- C. physics
- D. pharmacology
Correct answer: B
Rationale: Biochemistry is the correct answer because it focuses on understanding the chemical processes related to nutrition and how nutrients affect the body. Anatomy (choice A) primarily deals with the structure of organisms, not the chemical processes of nutrition. Physics (choice C) deals with energy and matter, not specifically related to nutrition. Pharmacology (choice D) focuses on drugs and their interactions with the body, not directly related to nutrition and its effects on health.
3. Which age group is particularly vulnerable to malnutrition?
- A. Infants
- B. Teenagers
- C. Young adults
- D. Middle-aged adults
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.
4. Exchange Lists for Meal Planning was originally intended as a meal-planning tool for people who have:
- A. cancer.
- B. diabetes.
- C. hypertension.
- D. heart disease.
Correct answer: B
Rationale: The correct answer is B: diabetes. Exchange Lists for Meal Planning were originally created to assist individuals with diabetes in managing their diet by providing a structured approach to balanced food exchanges. This system helps individuals regulate their blood sugar levels and maintain overall health. Choices A, C, and D are incorrect because Exchange Lists for Meal Planning were not primarily developed for individuals with cancer, hypertension, or heart disease.
5. In addition to calcium, the major minerals needed to build and maintain bone tissue include:
- A. potassium
- B. iron
- C. phosphorus
- D. fluoride
Correct answer: C
Rationale: The correct answer is C: phosphorus. Phosphorus, along with calcium, is essential for bone health and maintenance. Potassium (choice A) is important for muscle function, iron (choice B) is crucial for red blood cell production, and fluoride (choice D) helps prevent tooth decay but is not a major mineral needed for bone tissue.
