1. Which individual would be at the greatest risk for deficiencies in water-soluble vitamins?

• A. An individual who regularly consumes fruits and vegetables.
• B. An individual with a high intake of dairy products.
• C. An individual who consumes a diet high in processed foods.
• D. An individual who frequently eats organ meats.

Correct answer: C

Rationale: The correct answer is 'An individual who consumes a diet high in processed foods.' Processed foods are often deficient in water-soluble vitamins such as vitamin C and B vitamins, which can lead to deficiencies. On the other hand, fruits, vegetables, and organ meats are rich sources of these vitamins, so individuals who consume these regularly are less likely to develop deficiencies. While dairy products do contain some water-soluble vitamins, they are not depleted as quickly as they are in a diet high in processed foods, making a deficiency less likely.

2. Why is atherosclerosis dangerous to arterial function?

• A. It diminishes central circulation
• B. It causes decreased blood pressure on artery walls
• C. It narrows the arterial lumen so a clot can easily block it
• D. It increases arterial elasticity

Correct answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.

3. Which of the following is not a desirable blood lipid value?

• A. low total cholesterol
• B. high LDL
• C. high HDL
• D. low blood triglycerides

Correct answer: B

Rationale: The correct answer is B. High levels of LDL (low-density lipoprotein) cholesterol are undesirable as they are associated with an increased risk of cardiovascular disease. Therefore, low total cholesterol (choice A), high HDL (choice C), and low blood triglycerides (choice D) are considered desirable blood lipid values. Low total cholesterol is beneficial as high levels can increase the risk of heart disease. High HDL cholesterol is considered good as it helps remove LDL cholesterol from the arteries. Low blood triglycerides are also preferred as high levels are associated with an increased risk of heart disease.

4. What chronic disease has been associated with increased risks of dental problems?

• A. diabetes mellitus
• B. chronic obstructive pulmonary disease
• C. Addison's disease
• D. asthma

Correct answer: A

Rationale: Diabetes mellitus is associated with an increased risk of dental problems, including gum disease and tooth loss, due to high blood sugar levels. While chronic obstructive pulmonary disease (COPD), Addison's disease, and asthma may have oral health implications, diabetes mellitus is specifically known for its strong association with dental issues.

5. Which type of bread, cereal, or pasta would most likely be recommended for a patient on a fat-restricted diet?

• A. popcorn
• B. fried rice
• C. English muffins
• D. granola

Correct answer: C

Rationale: English muffins would be the most suitable option for a patient on a fat-restricted diet. They are typically lower in fat compared to fried rice, granola, and popcorn with butter. Popcorn, fried rice, and granola are higher in fat content and may not be the best choice for individuals on a fat-restricted diet.
