1. Which two dietary components may help decrease blood cholesterol levels?

• A. Omega-3 fatty acids and soluble fiber
• B. Short-chain fatty acids and insoluble fiber
• C. Trans fatty acids and potassium
• D. Cis fatty acids and calcium

Correct answer: A

Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.

2. Which of the following are the primary bacteria involved in the initiation of dental caries?

• A. Streptococcus mutans and Lactobacillus species
• B. Salmonella and Listeria species
• C. Streptococcus, Lactobacillus, and Salmonella species
• D. Listeria, Botulinum species, and Escherichia coli

Correct answer: A

Rationale: The correct answer is A: Streptococcus mutans and Lactobacillus species. These bacteria are primarily responsible for initiating dental caries by fermenting carbohydrates and producing acids that demineralize enamel. Choice B, Salmonella and Listeria species, are not the primary bacteria involved in dental caries. Choice C includes Salmonella which is not a primary culprit in dental caries. Choice D lists Listeria, Botulinum species, and Escherichia coli, none of which are the primary bacteria associated with initiating dental caries.

3. The home health nurse visits older adult clients at an assisted living center. Which foods should the nurse recommend to correct the main nutrient deficits for this population?

• A. Carbohydrates
• B. Oily fish and krill oil
• C. Yellow vegetables
• D. Dairy products

Correct answer: D

Rationale: The correct answer is D: Dairy products. Older adults are often deficient in calcium and vitamin D, which are abundant in dairy products. These nutrients are essential for maintaining bone health. Choice A (Carbohydrates) is incorrect because while carbohydrates are an essential nutrient, they are not specifically addressing the main nutrient deficits for older adults. Choice B (Oily fish and krill oil) is incorrect as these foods are sources of omega-3 fatty acids and not specifically addressing the main nutrient deficits common in older adults. Choice C (Yellow vegetables) is incorrect because although vegetables are important for overall health, they do not directly address the main nutrient deficits typically seen in older adults.

4. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?

• A. triglycerides > 150 mg/dL
• B. BMI > 31
• C. LDL cholesterol < 128 mg/dL
• D. blood pressure of 128/82 mmHg

Correct answer: B

Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.

5. Which nutrients might people who follow a vegan diet be deficient in?

• A. Vitamin B12
• B. Vitamin C
• C. Vitamins A and D
• D. Calcium

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.
