ATI Nutrition Proctored Exam 2023
1. Are the following statements both true: 'Most excess energy intake, whether from protein, carbohydrate, alcohol, or fat, is stored in the liver' and 'Fat is a good source of energy, but the preferred fuel is protein'?
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true, but the second is false
- D. The first statement is false, but the second is true
Correct answer: B: Both statements are false
Rationale: Both of the given statements are false. The first statement is inaccurate because the primary location for excess energy storage is not the liver, but rather adipose tissue where it is stored as fat. While the liver does have a role in energy storage and metabolism, it is not the main storage site for excess intake. The second statement is also incorrect. Although fat and protein can be used as sources of energy, the body's preferred source of energy is carbohydrates. They break down more efficiently and are easier for the body to use. The body prefers to conserve protein for other essential functions, such as tissue repair and the production of enzymes. Therefore, protein is not the preferred fuel source.
2. You are a researcher testing out the effects of a new food molecule—MEGA—on bone health. In order to know if it actually travels to bone cells in the body, you first need to find out if it gets absorbed in the bloodstream. You eat a food containing MEGA, and you measure the molecule in your urine and feces. You only detect MEGA in the feces. Was MEGA absorbed?
- A. No—absorbed compounds show up in urine, not feces
- B. Yes—absorbed compounds show up in feces, not urine
- C.
- D.
Correct answer: A
Rationale: If MEGA was only detected in feces and not in urine, it was not absorbed into the bloodstream. Absorbed compounds typically appear in urine after processing by the body. The correct answer is A because the presence of a compound in feces indicates that it was not absorbed by the body and passed through the digestive system. Choices B, C, and D are incorrect as they do not align with the process of absorption and excretion in the body.
3. During the later stages of chronic kidney disease, what is the recommended protein intake in grams per kilogram of body weight per day?
- A. 0.6 to 0.75
- B. 1.2 to 1.55
- C. 1.0 to 1.2
- D. 0.8 to 1.0
Correct answer: A
Rationale: In the later stages of chronic kidney disease, the recommended protein intake is typically restricted to 0.6 to 0.75 grams per kilogram of body weight per day. This lower protein intake helps reduce the workload on the kidneys, as excessive protein can be challenging for the kidneys to process. Choice B (1.2 to 1.55) is incorrect as it suggests a higher protein intake, which is not recommended for individuals with advanced kidney disease. Choices C (1.0 to 1.2) and D (0.8 to 1.0) also advocate for protein intakes higher than what is typically advised for individuals in later stages of chronic kidney disease.
4. Riboflavin
- A. Vitamin B1
- B. Vitamin B2
- C. Vitamin B3
- D. Vitamin B12
Correct answer: B
Rationale: Riboflavin is also known as Vitamin B2, which is important for energy production and the metabolism of fats, drugs, and steroids.
5. Which nutrient is most important for wound healing in a patient post-surgery?
- A. Vitamin C
- B. Protein
- C. Iron
- D. Calcium
Correct answer: B
Rationale: Protein is essential for tissue repair and wound healing.
