ATI Nutrition Practice Questions Questions
Question 1 of 9
Which biomolecule is responsible for the storage and transfer of genetic information?
Correct Answer: D
Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
Question 2 of 9
Select all that apply. Characteristics of the 2 main types of essential fatty acids discussed in class include:
Correct Answer: A
Rationale: The correct answer is A: 'they must be supplied by the diet.' Essential fatty acids, like omega-3 and omega-6, cannot be produced by the body and must be obtained through the diet. They are polyunsaturated fatty acids, playing vital roles in inflammation and cell membrane structure. Choice B is incorrect because essential fatty acids cannot be produced by dehydrogenation, a process of removing hydrogen. Choice C is incorrect as not all essential fatty acids are anti-inflammatory; some have pro-inflammatory roles. Choice D is incorrect because not all essential fatty acids are polyunsaturated; omega-9, for example, is a monounsaturated essential fatty acid.
Question 3 of 9
What food would most likely be included in Level 1 of the National Dysphagia Diet?
Correct Answer: D
Rationale: The correct answer is D, plain yogurt. Level 1 of the National Dysphagia Diet includes pureed or smooth foods that are easy to swallow. Plain yogurt fits this criteria as it is smooth and can be easily consumed without posing a risk of choking. Choices A, B, and C are not typically included in Level 1 of the diet. Peanut butter, oatmeal, and fruit preserves are not usually suitable for individuals on Level 1 of the National Dysphagia Diet as they may present a choking hazard or are not in a pureed or smooth form.
Question 4 of 9
Which nutrient is most important for the prevention of osteoporosis?
Correct Answer: C
Rationale: Calcium is the most important nutrient for bone health and the prevention of osteoporosis. Calcium plays a crucial role in maintaining bone density and strength. Vitamin A is important for vision and immune function but is not directly related to bone health. Iron is essential for oxygen transport in the blood, while protein is important for muscle growth and repair. However, in the context of preventing osteoporosis, calcium is the key nutrient.
Question 5 of 9
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 6 of 9
Although a balanced diet is essential for tissue healing and repair, which of the following should the dental hygienist identify as the nutrient of highest priority for a patient with gingivitis or periodontal disease?
Correct Answer: B
Rationale: Vitamin C is crucial for collagen production and connective tissue repair, making it a key nutrient for healing gingival tissues in patients with gingivitis or periodontal disease. Carbohydrates are a source of energy and not directly related to tissue repair. Vitamin D is important for bone health but is not the highest priority for gingival tissue healing. Monosaccharides are simple sugars and not as essential for tissue repair as Vitamin C.
Question 7 of 9
What are the potential consequences of damage to the stomach?
Correct Answer: C
Rationale: Damage to the stomach can lead to a reduced ability to produce gastric acid (Choice C) and intrinsic factor, the latter of which is crucial for vitamin B12 absorption (Choice D). That's why these two choices are correct. The stomach doesn't play a direct role in the digestion of carbohydrates (Choice A) as this process primarily occurs in the small intestine with the help of pancreatic enzymes. Similarly, bile is produced by the liver and stored in the gallbladder, not the stomach, hence stomach damage wouldn't lead to an inability to produce or secrete bile (Choice B).
Question 8 of 9
A condition that often progresses to become type 2 diabetes mellitus is:
Correct Answer: D
Rationale: Impaired glucose tolerance is a pre-diabetic state characterized by higher than normal blood sugar levels. It is often associated with insulin resistance and can progress to type 2 diabetes mellitus. Type 1 diabetes mellitus (Choice A) is an autoimmune condition where the body attacks insulin-producing cells, leading to a lack of insulin production. High blood pressure (Choice B) and chronic pancreatitis (Choice C) are not directly linked to the progression to type 2 diabetes mellitus.
Question 9 of 9
Individuals who use antiretroviral drugs frequently develop insulin resistance and _____.
Correct Answer: C
Rationale: The correct answer is C: hyperlipidemia. Antiretroviral drugs can often lead to elevated lipid levels (hyperlipidemia), which is a common side effect of this therapy. This increase in lipids can contribute to cardiovascular risk. Hypertension (choice A) is not typically associated with antiretroviral drug use. Hypothyroidism (choice B) and fluid retention (choice D) are also not commonly linked to antiretroviral therapy.
