ATI Nutrition Practice Questions Questions
Question 1 of 5
Each of the following foods has cariostatic properties, with one exception. Which food is the exception?
Correct Answer: B
Rationale: Cariostatic foods are those that contribute to the prevention of tooth decay. Eggs, cheese, and seafood are all cariostatic foods, as they can aid in protecting against tooth decay. On the contrary, instant oatmeal does not possess these cariostatic properties. Due to its processed nature, it is more fermentable and cariogenic, which means it can encourage cavity formation. Although it is not directly harmful to the teeth, it does not provide the same defensive benefits against tooth decay as the other choices do. Therefore, 'Instant oatmeal' is the exception among these foods and is the correct answer.
Question 2 of 5
Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?
Correct Answer: B
Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.
Question 3 of 5
Because of increasing cases of fluorosis, low levels of fluoride are added to commercial infant formula. Breast milk provides low levels of fluoride.
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
What is the most common nutritional disorder for the older adult?
Correct Answer: A
Rationale: The correct answer is A: Obesity. Among older adults, obesity is the most common nutritional disorder. This is often attributed to reduced physical activity levels and changes in metabolism that occur with aging. Choice B (Underweight) is less common among older adults as compared to obesity. While choices C (Vitamin deficiency) and D (Dehydration) are important nutritional issues, they are generally not as prevalent as obesity in the older adult population.
Question 5 of 5
The purpose of the health history is to identify health-related considerations and medications that may cause nutritional risk. Many medications, such as prednisone, have drug-nutrient interactions that can influence nutrient needs.
Correct Answer: A
Rationale: Both statements are true. The health history aims to uncover health-related factors that could pose nutritional risks, including medications like prednisone that may have interactions affecting nutrient requirements. Choice B is incorrect as both statements are accurate, emphasizing the significance of health history in assessing nutritional concerns.
