PN Nutrition Assessment ATI
1. 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.
2. What is the primary function of protein in the diet?
- A. supply energy.
- B. synthesize vitamins.
- C. build and repair tissue.
- D. store glycogen.
Correct answer: C
Rationale: The primary function of protein in the diet is to build and repair tissues. Proteins are essential for the growth, maintenance, and repair of body tissues like muscles, skin, and organs. While proteins can be a source of energy, their primary role is not to supply energy, making choice A incorrect. Choice B is also incorrect as proteins do not synthesize vitamins; rather, they are essential nutrients themselves. Choice D is inaccurate because glycogen is a form of stored glucose in the body, not a function of protein.
3. Where are sugar alcohols most likely to be found?
- A. Fermented foods.
- B. Low-calorie foods.
- C. Fruits and vegetables.
- D. Fiber supplements.
Correct answer: B
Rationale: Sugar alcohols are commonly found in low-calorie foods as sweetening agents without the calorie content of regular sugars. Choices A, C, and D are incorrect because sugar alcohols are not typically found in fermented foods, fruits, vegetables, or fiber supplements. Therefore, the correct answer is B.
4. How can cholesterol absorption be decreased?
- A. Vitamin K.
- B. Plant sterols.
- C. Trans fats.
- D. Phospholipids.
Correct answer: B
Rationale: The correct answer is B: Plant sterols. Plant sterols can reduce cholesterol absorption by competing with cholesterol for absorption sites. Vitamin K, choice A, does not have a significant impact on cholesterol absorption. Trans fats, choice C, are known to increase cholesterol levels rather than decrease absorption. Phospholipids, choice D, play a role in cell structure and are not directly involved in reducing cholesterol absorption.
5. After absorption, the end products of carbohydrate and protein digestion enter the:
- A. enterohepatic circulation.
- B. gastrointestinal circulation.
- C. common bile duct.
- D. portal blood system.
Correct answer: D
Rationale: The correct answer is D: portal blood system. After absorption, carbohydrates and proteins are transported via the portal blood system to the liver for further processing and distribution to the rest of the body. Choices A, B, and C are incorrect. Enterohepatic circulation refers to the recycling of compounds between the liver and the intestines, not the direct route for absorbed nutrients. Gastrointestinal circulation is a vague and non-specific term, not specifically related to the transport of absorbed nutrients. The common bile duct is involved in transporting bile from the liver and gallbladder to the small intestine, not the end products of carbohydrate and protein digestion.
