1. Which food is recommended for a client trying to increase their intake of calcium?

• A. Apples
• B. Yogurt
• C. Chicken
• D. Pasta

Correct answer: B

Rationale: Yogurt is high in calcium, which is essential for bone health.

2. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

3. How is the stomach protected from damage by gastric acid?

• A. enzymes present in the stomach
• B. a protective bacteria in the stomach
• C. bicarbonate present in the stomach
• D. the mucus lining of the stomach

Correct answer: D

Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.

4. Which is most likely to initiate periodontal disease?

• A. Nutrient deficiencies
• B. Nutrient excesses
• C. Nutrient imbalances
• D. Plaque biofilm

Correct answer: D

Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.

5. A healthcare provider is providing teaching about nutrition to a group of clients. The healthcare provider should include that which of the following foods contains the highest level of thiamine per serving?

• A. 1 hard-boiled egg
• B. 1 cup dried pears
• C. 1 cup whole grain wheat flour
• D. 1 cup Brussels sprouts

Correct answer: C

Rationale: Whole grain wheat flour contains the highest level of thiamine per serving compared to the other options provided. Thiamine, also known as Vitamin B1, is essential for energy metabolism. While eggs, dried pears, and Brussels sprouts are nutritious foods, they do not contain as high a level of thiamine as whole grain wheat flour. Therefore, the correct choice is whole grain wheat flour in this case.
