ATI Nutrition Proctored Exam 2023

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.

Correct Answer: A

Rationale: Acquired Immunodeficiency Syndrome (AIDS) is known for a variety of oral manifestations such as oral candidiasis, hairy leukoplakia, herpetic ulcerations, Kaposi's sarcoma, xerostomia, and severe periodontal disease. These symptoms are not typically associated with acute leukemia, anorexia nervosa, or bulimia. Acute leukemia usually presents with symptoms like fatigue, frequent infections, and easy bruising. Anorexia nervosa and bulimia are eating disorders, thus their primary symptoms are primarily associated with eating habits and body weight, not oral health.

Correct Answer: D

Rationale: The primary purpose of dietary fiber in the diet is to reduce cholesterol levels. While it does aid in digestion by promoting regular bowel movements, its main role is in lowering cholesterol. Choice A is partially correct but not the primary purpose. Choice B is incorrect as fiber is not a direct source of energy. Choice C is also incorrect as the primary role of fiber is not in the absorption of vitamins.

Correct Answer: C

Rationale: Mechanical digestion involves physical movements that break down food in the digestive tract. Segmentation (choice B) and peristalsis (choice D), which are both movements of the muscles in the digestive tract, are examples of this type of digestion. Heat (choice A), on the other hand, is related to chemical digestion, not mechanical digestion. Therefore, choice C (Option B and D) is the correct answer as it includes both examples of mechanical digestion provided in the choices. Choices A and D are incorrect because heat (choice A) is not a mechanical digestion process, and peristalsis (choice D) is a movement that helps propel food along the digestive tract but is not directly involved in breaking down food physically.

Correct Answer: D

Rationale: The correct answer is D. Contrary to the statement, bone loss begins earlier in women, particularly after menopause, due to the decrease in estrogen levels. This drop in estrogen accelerates bone loss, contributing to the higher prevalence of osteoporosis in women. Choices A, B, and C are more likely reasons for the increased prevalence of osteoporosis in women. Women generally have smaller bodies, lower bone mass compared to men, and may consume less calcium, all of which are significant factors contributing to the higher incidence of osteoporosis in women.
