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. Where in the body are microvilli located, facilitating the absorption of most nutrients?

• A. Stomach
• B. Pancreas
• C. Large Intestine
• D. Small Intestine

Correct answer: D

Rationale: The correct answer is D: Small Intestine. Microvilli are present in the small intestine, significantly increasing its surface area for efficient absorption of nutrients. The small intestine is the primary site for nutrient absorption in the body. The stomach (choice A) primarily functions to break down food with its acidic environment but is not where most nutrients are absorbed. The pancreas (choice B) produces enzymes to aid in digestion but does not directly absorb nutrients. The large intestine (choice C) mainly absorbs water and electrolytes from undigested food, rather than nutrients.

3. Can bacterial plaque metabolize sucrose, lactose, and fructose? Is fructose, also known as levulose and found naturally in honey, less cariogenic than sucrose and lactose?

• A. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
• B. No, bacterial plaque cannot metabolize these sugars, and fructose is not less cariogenic.
• C. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
• D. No, bacterial plaque cannot metabolize these sugars, but yes, fructose is less cariogenic.

Correct answer: A

Rationale: The first statement is correct as bacterial plaque can indeed metabolize sucrose, lactose, and fructose. However, the second statement is inaccurate. Fructose, despite being found naturally in honey and known also as levulose, is not less cariogenic than either sucrose or lactose. This means that its consumption does not result in fewer cavities or tooth decay. Therefore, the correct answer is that bacterial plaque can metabolize these sugars, but fructose is not less cariogenic. Choices B, C, and D are incorrect because they either wrongly assert that bacterial plaque cannot metabolize these sugars or wrongly claim that fructose is less cariogenic.

4. In a patient with osteoporosis, which mineral is essential to prevent further bone loss?

• A. Iron
• B. Phosphorus
• C. Magnesium
• D. Calcium

Correct answer: D

Rationale: Calcium is crucial in preventing bone loss in patients with osteoporosis.

5. Which assessment finding indicates effective treatment for hyperemesis gravidarum?

• A. The client's glucose is within the normal range.
• B. The client ate 80% of their breakfast tray.
• C. There is no protein in the client's urine.
• D. The client's blood pressure is 145/75 mmHg.

Correct answer: B

Rationale: Improved appetite and food intake is an indication of effective treatment.
