Nutrition ATI Proctored Exam Questions
Question 1 of 5
What is the preferred fuel for the cells lining the colon?
Correct Answer: A
Rationale: Short-chain fatty acids are the preferred fuel for the cells lining the colon. They provide energy and support gut health by serving as a fuel source for these cells. Long-chain fatty acids are not the preferred fuel for colon cells as they are harder to digest and absorb in this part of the digestive system. Amino acids are the building blocks of proteins and not the primary energy source for colon cells. Glucose is the main energy source for most cells in the body, but colon cells prefer short-chain fatty acids.
Question 2 of 5
The major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet.
Correct Answer: B
Rationale: It is false that the major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet. While dietary cholesterol can have some impact on total cholesterol levels, it is not the major determinant. The amount and types of fats consumed, particularly saturated and trans fats, have a more significant impact on blood cholesterol levels. Therefore, a diet high in these types of fats can lead to high cholesterol, irrespective of the amount of dietary cholesterol consumed. This is why it is essential to maintain a balanced diet with a limited intake of saturated and trans fats.
Question 3 of 5
A common comorbidity in patients with Chronic Kidney Disease (CKD) is:
Correct Answer: B
Rationale: Malnutrition is a common comorbidity in patients with Chronic Kidney Disease (CKD). This is mainly due to factors such as dietary restrictions, poor appetite, and the body's increased nutritional needs as it struggles to deal with the disease. Liver disease (Choice A) is not typically associated directly with CKD, although both conditions may coexist in some patients. Acute renal failure (Choice C) is not a comorbidity but a severe and potentially lethal progression of CKD. Difficulty breathing (Choice D) is not a comorbidity but can be a symptom of severe kidney disease or other underlying conditions. However, malnutrition is more commonly observed in CKD patients compared to difficulty breathing.
Question 4 of 5
Why are diets that contain less than 10% of kcalories as fat not recommended?
Correct Answer: D
Rationale: Diets that contain less than 10% of kcalories as fat are not recommended because they would lead to inadequate intake of essential fatty acids, which are crucial for various bodily functions like hormone production, brain function, and cell membrane structure. Option A is incorrect because reducing fat intake does not necessarily mean increasing carbohydrate intake excessively. Option B is incorrect as it introduces a new concept of using fat replacers, which is not directly related to the issue of essential fatty acid intake. Option C is incorrect as the primary concern with low-fat diets is the insufficiency of essential fatty acids, not the adequacy of them.
Question 5 of 5
During lactation, where is lactose synthesized in the body?
Correct Answer: B
Rationale: The correct answer is B: Breast. Lactose is synthesized in the breast during lactation to produce breastmilk. The liver is responsible for various metabolic functions but does not synthesize lactose. The kidney's primary role is in filtering blood and regulating electrolytes, not lactose synthesis. The pancreas is involved in producing digestive enzymes and insulin, not lactose synthesis.
