ATI Nutrition Proctored Exam 2019 Answers
1. Which condition may benefit from branched chain amino acids (leucine, isoleucine, and valine)?
- A. cancer-related malnutrition
- B. marasmus
- C. cardiovascular disease
- D. severe depression
Correct answer: A
Rationale: Branched chain amino acids, such as leucine, isoleucine, and valine, are essential in preventing muscle breakdown. Therefore, they may be particularly important for a patient with cancer-related malnutrition, where maintaining muscle mass is crucial. Marasmus is a severe form of malnutrition characterized by energy deficiency, not specifically related to cancer. Cardiovascular disease and severe depression do not have a direct correlation with the need for branched chain amino acids to prevent muscle breakdown.
2. What types of muscular movement occur in the intestine?
- A. Longitudinal and circular.
- B. Expulsion and traction.
- C. Tonus and clonus.
- D. Intermittent and continuous.
Correct answer: A
Rationale: The correct answer is A: Longitudinal and circular. Longitudinal and circular muscles are responsible for the movements that help propel food through the intestine. Choice B, expulsion and traction, is incorrect as these terms do not specifically relate to the types of muscular movement in the intestine. Choice C, tonus and clonus, refers to different types of muscle contractions and are not the primary movements in the intestine. Choice D, intermittent and continuous, does not accurately describe the specific types of muscular movement that occur in the intestine.
3. A characteristic of saturated fats is that they are:
- A. mostly found in animal products.
- B. solid at room temperature.
- C. composed of many double bonds.
- D. found primarily in vegetable products.
Correct answer: A
Rationale: The correct answer is A: 'mostly found in animal products.' Saturated fats are primarily found in animal products such as meat, dairy, and eggs. They are typically solid at room temperature. Choice B is incorrect because saturated fats are solid at room temperature, not liquid. Choice C is incorrect because saturated fats do not have double bonds; they have single bonds between carbon atoms. Choice D is incorrect because saturated fats are mainly found in animal products, not vegetable products.
4. The process of breaking down body protein into amino acids for energy is known as:
- A. Deamination.
- B. Transamination.
- C. Transcription.
- D. Catabolism.
Correct answer: D
Rationale: The correct answer is D: Catabolism. Catabolism involves the breakdown of body proteins into amino acids to be used as energy when there is an inadequate dietary intake. Choices A and B, deamination and transamination, involve the removal and transfer of amino groups, respectively, but not the breakdown of body proteins. Choice C, transcription, is a process in genetics where DNA is used to create mRNA, not related to breaking down body proteins.
5. Exchange Lists for Meal Planning group foods that are equivalent in their:
- A. weight.
- B. serving size.
- C. micronutrient content.
- D. macronutrient content.
Correct answer: D
Rationale: The Exchange Lists for Meal Planning categorize foods based on their macronutrient content, such as carbohydrate, protein, and fat. These lists help individuals make food choices while ensuring similar amounts of macronutrients are consumed. Therefore, the correct answer is D. Choices A, B, and C are incorrect because Exchange Lists focus on macronutrient content, not weight, serving size, or micronutrient content.
