ATI Nutrition Practice A

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.

Correct Answer: D

Rationale: Malnutrition is often associated with a weakened immune system. This is because when the body is not sufficiently nourished, it lacks the necessary nutrients to maintain a well-functioning immune system, making patients more vulnerable to infections and other health complications. This can potentially increase mortality rates and prolong hospital stays, contrary to choice C. Choices A and B are incorrect as malnutrition does not lead to decreased health care costs or high blood pressure. In fact, it may increase health care costs due to the potential for increased complications and extended hospital stays.

Correct Answer: D

Rationale: Coconut oil is a plant-based oil that is high in saturated fat, unlike most other plant oils, which are typically unsaturated.

Correct Answer: D

Rationale: The correct answer is 'D. All of the above'. This is because, according to regulations, food labels must include the information on total fat, saturated fat, and trans fat. These types of fats are crucial for consumers to monitor, as they can significantly affect heart health. Choices A, B, and C are all correct, but they are only parts of the total information that must be provided. Therefore, the most comprehensive answer is 'D. All of the above'.

Correct Answer: B

Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.
