1. What is the term for a barrier that prevents the normal emptying of stomach contents into the duodenum?

• A. Dumping syndrome
• B. Gastritis
• C. Gastric outlet obstruction
• D. Hypochlorhydria

Correct answer: C

Rationale: Gastric outlet obstruction refers to a condition where the opening between the stomach and the duodenum is blocked, preventing the normal passage of food. This is why choice 'C' is correct. 'A: Dumping syndrome' is incorrect because it is a condition where stomach contents move too quickly through the small intestine, not a barrier preventing emptying. 'B: Gastritis' is inflammation of the stomach lining, not a blockage of the outlet. 'D: Hypochlorhydria' refers to low stomach acid, which may affect digestion but does not create a physical barrier blocking the outlet of the stomach.

2. Can soluble fibers be fermented by gut bacteria?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: Soluble fibers can indeed be fermented by gut bacteria in the large intestine, leading to the production of beneficial short-chain fatty acids. This fermentation process is important for gut health and provides various health benefits. Therefore, the statement is true. Choice B is incorrect as it contradicts the known scientific fact that soluble fibers can be broken down by gut bacteria through fermentation.

3. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

4. After reviewing the health and dental histories, the dental hygienist has adequate information to begin dietary counseling with the patient. Providing a standardized, low-carbohydrate menu is sufficient for most patients with a high caries rate.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: Both statements are false. Dietary counseling should be personalized, and a standardized low-carbohydrate menu is not sufficient for all patients.

5. An elderly man is hospitalized with a diagnosis of malnutrition three months following his wife's death. What risk factor for malnutrition does this scenario illustrate?

• A. A history of chronic illness
• B. Depression or social isolation
• C. Age
• D. Impaired mobility

Correct answer: B

Rationale: This scenario illustrates depression or social isolation as a risk factor for malnutrition. After the death of his wife, the elderly man may have experienced depression or social isolation, which can lead to decreased food intake and poor nutritional status. Although age, chronic illness, and impaired mobility can also contribute to malnutrition, they are not the primary factors described in this scenario. The history of chronic illness (Choice A) and impaired mobility (Choice D) were not mentioned in the scenario, and while age (Choice C) is a factor, it's not the main factor depicted in this case.
