ATI Nutrition Proctored Exam 2023 Test Bank Questions
Question 1 of 5
For a patient on a ketogenic diet, which macronutrient is primarily increased?
Correct Answer: C
Rationale: The correct answer is C: Fats. A ketogenic diet is characterized by high fat intake, moderate protein intake, and very low carbohydrate intake. This diet aims to shift the body's metabolism to use fat as the primary source of energy instead of carbohydrates. Increasing fat intake while reducing carbohydrates is essential for achieving and maintaining a state of ketosis. Therefore, choices A, B, and D are incorrect as they do not align with the macronutrient adjustments required for a ketogenic diet.
Question 2 of 5
Each statement is true of swallowing and processing food, except one. Which is the exception?
Correct Answer: C
Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.
Question 3 of 5
The term associated with loss of taste is:
Correct Answer: B
Rationale: The correct answer is B, 'Hypogeusia.' Hypogeusia refers to a diminished sense of taste, which can impact nutritional intake, especially in older adults. Xerostomia (choice A) is dry mouth, Dysphagia (choice C) is difficulty swallowing, and Anosmia (choice D) is the loss of the sense of smell. These conditions are different from loss of taste, making them incorrect choices for this question.
Question 4 of 5
Where does most nutrient digestion and absorption occur?
Correct Answer: B
Rationale: The small intestine is the correct answer. It is the primary site for nutrient digestion and absorption in the digestive system. The small intestine plays a crucial role in breaking down carbohydrates, proteins, and fats into forms that can be absorbed by the body. While the large intestine absorbs water and electrolytes, the majority of nutrient absorption occurs in the small intestine. The stomach primarily functions in the initial digestion of proteins, and the mouth begins the mechanical breakdown of food through chewing.
Question 5 of 5
Carmen discovers that the DASH diet contains more fiber and ____ compared to that of the typical American diet.
Correct Answer: C
Rationale: The correct answer is C: 'potassium.' The DASH diet is rich in potassium, which helps lower blood pressure, making it more effective than the typical American diet, which is often low in this essential mineral. Choice A, 'vitamin C,' is incorrect as the comparison is about fiber and another nutrient, not vitamin C. Choice B, 'iron,' is incorrect as the discussion is about fiber and a mineral that helps lower blood pressure, not iron. Choice D, 'sodium,' is incorrect as the DASH diet actually focuses on reducing sodium intake for better blood pressure control, so it wouldn't be a nutrient found in higher amounts compared to the typical American diet.
