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.

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.

Correct Answer: B

Rationale: Engorgement occurs when the breasts become overly full, leading to discomfort and sometimes difficulty with latching. It can be relieved by feeding or expressing milk. Mastitis, choice A, is characterized by breast inflammation usually caused by an infection. Letdown, choice C, refers to the release of milk from the breast. Galactorrhea, choice D, is the spontaneous flow of milk from the breast unassociated with childbirth or nursing.

Correct Answer: D

Rationale: The correct answer is 'antioxidants and phytochemicals'. Antioxidants and phytochemicals help reduce oxidative damage in the body, contributing to healthy aging and a lower risk of chronic diseases. This is the same effect observed in animals when their energy intake is restricted. The other choices are incorrect as there is no direct evidence connecting reduced oxidative damage with diets high in fiber and carbohydrates, fatty acids and protein, or probiotics.

Correct Answer: D

Rationale: The DASH Eating Plan is designed to lower blood pressure and is most effective when daily sodium intake is limited to 1500 milligrams or less. Therefore, choice D is the correct answer. Choices A (1000 milligrams), B (2500 milligrams), and C (3000 milligrams) are incorrect because they either fall below or exceed the recommended daily sodium intake for the DASH Eating Plan.

Correct Answer: A

Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.

Correct Answer: C

Rationale: People who adhere to a vegan diet might indeed be deficient in vitamins A and D, which are primarily found in animal-derived foods. While vitamin B12 and calcium can also be lacking in a vegan diet, these were not choices given that would correctly answer the question. Vitamin C, on the other hand, is widely available in numerous plant-based foods, making it less likely for vegans to be deficient in it. Therefore, the correct answer is 'Vitamins A and D'. It's important to note that deficiencies can be avoided through careful meal planning or supplementation.

Correct Answer: A

Rationale: Both statements are indeed true. Many adolescents undergoing orthodontic treatment often neglect proper nutrition and oral hygiene, leading to subpar practices in these areas. It's common for them to be less attentive to these aspects due to various factors. A dental hygienist's role includes motivating these patients towards better self-care practices. One effective approach is by emphasizing that good nutrition and oral hygiene can significantly enhance their appearance. This approach is particularly effective for adolescents as they are often highly conscious about their looks. The other choices are incorrect because they suggest that one or both of the statements are false, which is not the case.

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.
