ATI Nutrition Practice Questions Questions
Question 1 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 2 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 3 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.
Question 4 of 5
Which neuromuscular disease is characterized by abnormal chewing and swallowing patterns, tremors of the mandible, lip, and tongue, frequent drooling, and holding food in the mouth for extended periods?
Correct Answer: B
Rationale: The correct answer is B, Parkinson's disease. Parkinson's disease is characterized by abnormal chewing and swallowing patterns, tremors of the mandible, lip, and tongue, frequent drooling, and difficulties in oral functions like holding food in the mouth. Developmental disabilities (Choice A) do not specifically cause these symptoms related to neuromuscular function. Epilepsy (Choice C) is a neurological disorder characterized by recurrent seizures and does not typically present with the described symptoms. Diabetes mellitus (Choice D) is a metabolic disorder that affects blood sugar regulation and does not directly cause the neuromuscular symptoms mentioned in the question.
Question 5 of 5
Each of the following is a function of the liver except one. Which one is the exception?
Correct Answer: B
Rationale: The correct answer is B. The liver does not convert monosaccharides to triglycerides; instead, it converts monosaccharides to glucose or glycogen. Choice A is correct because the liver plays a role in regulating the levels of various nutrients in the bloodstream. Choice C is correct as the liver breaks down stored glycogen into glucose to maintain blood sugar levels. Choice D is correct as the liver oxidizes digestive end products to provide energy. Therefore, only choice B is incorrect as the liver does not convert monosaccharides to triglycerides.
