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 dietary supplement is often recommended for patients taking statins to lower cholesterol?

• A. Iron
• B. Coenzyme Q10
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: Coenzyme Q10 is often recommended for patients on statins because it may help reduce muscle pain, a common side effect of these medications. Iron (Choice A) is not typically recommended for patients taking statins to lower cholesterol. Calcium (Choice C) and Magnesium (Choice D) are not specifically indicated for addressing muscle pain associated with statin use, making them less suitable choices in this scenario.

3. In a patient with chronic kidney disease, which dietary modification is recommended?

• A. Increase protein intake
• B. Reduce potassium intake
• C. Increase sodium intake
• D. Reduce fiber intake

Correct answer: B

Rationale: Reducing potassium intake is important for patients with chronic kidney disease to prevent hyperkalemia.

4. A breastfeeding mother complains that she missed her son's last two feedings and now her breasts have become full, hard, and uncomfortable. This condition is known as _____.

• A. mastitis
• B. engorgement
• C. letdown
• D. galactorrhea

Correct answer: B

Rationale: Engorgement occurs when the breasts become overly full, leading to discomfort and sometimes difficulty with latching. It can be relieved by feeding or expressing milk. Mastitis, choice A, is characterized by breast inflammation usually caused by an infection. Letdown, choice C, refers to the release of milk from the breast. Galactorrhea, choice D, is the spontaneous flow of milk from the breast unassociated with childbirth or nursing.

5. 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.
