1. Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?
- A. 5
- B. 5.5
- C. 6
- D. 6.5
Correct answer: B
Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.
2. What food would most likely be included in Level 1 of the National Dysphagia Diet?
- A. peanut butter
- B. oatmeal
- C. fruit preserves
- D. plain yogurt
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.
3. What can be a potential consequence of consuming insufficient fat?
- A. constipation
- B. marasmus
- C. infertility
- D. diverticulitis
Correct answer: C
Rationale: The correct answer is C. Fat is crucial for the production of hormones, including reproductive hormones. Consuming too little fat can lead to hormonal imbalances, affecting fertility. Choices A, B, and D are incorrect. Constipation is more commonly associated with insufficient fiber intake, marasmus is severe malnutrition due to overall calorie deficiency, and diverticulitis is often related to low fiber intake and not specifically low fat consumption.
4. Which nutrient is most important for the prevention of osteoporosis?
- A. Vitamin A
- B. Iron
- C. Calcium
- D. Protein
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.
5. With which type of cancer is asbestos exposure most strongly associated?
- A. Liver cancer
- B. Peritoneal cancer
- C. Skin cancer
- D. Esophageal cancer
Correct answer: B
Rationale: Asbestos exposure is most strongly associated with peritoneal cancer, a type of cancer that affects the lining of the abdomen. While asbestos can potentially contribute to other types of cancer, there is a significant body of research indicating a robust correlation between asbestos exposure and peritoneal cancer. Asbestos exposure can also lead to mesothelioma, a cancer that affects the lining of the chest. The other options - liver cancer, skin cancer, and esophageal cancer - are not typically associated with asbestos exposure.
