1. Milk and other dairy products are preferred sources of calcium because lactose enhances calcium absorption.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. Milk and other dairy products are indeed preferred sources of calcium because they supply most of the available calcium. Additionally, lactose present in dairy products enhances calcium absorption, making them even more efficient sources of this essential mineral. The statement correctly identifies dairy products as preferred sources of calcium, and the reason explains how lactose contributes to better calcium absorption. The other choices are incorrect as they do not accurately assess the relationship between lactose, calcium absorption, and the preference for dairy products as sources of calcium.

2. The substance that is most supportive of bones and teeth is:

• A. Hemoglobin
• B. Collagen
• C. Insulin
• D. Pepsin

Correct answer: B

Rationale: Collagen is a key structural protein in bones and teeth, providing support and strength.

3. What is considered an acceptable LDL cholesterol level for children and adolescents?

• A. Less than 70 mg/dL
• B. Less than 110 mg/dL
• C. Less than 129 mg/dL
• D. Less than 170 mg/dL

Correct answer: B

Rationale: An LDL cholesterol level of less than 110 mg/dL is considered acceptable and healthy for children and adolescents. This level helps reduce the risk of cardiovascular diseases. Choices A, C, and D are incorrect because an LDL cholesterol level below 110 mg/dL is the recommended target for children and adolescents to maintain good heart health.

4. You are teaching your clients the difference between Type I (IDDM) and Type II (NDDM) diabetes. Which of the following statements is true?

• A. Both types of diabetes mellitus clients are prone to developing ketosis.
• B. Type II (NIDDM) is more common and preventable compared to Type I (IDDM) diabetes, which is genetic.
• C. Type I (IIDM) is characterized by fasting hyperglycemia.
• D. Type II (NIDDM) is characterized by abnormal immune response.

Correct answer: D

Rationale: The correct answer is D. Type II diabetes (NIDDM) is characterized by insulin resistance and a relative lack of insulin. It is not primarily characterized by an abnormal immune response. Option A is incorrect because only Type I diabetes clients are prone to developing ketosis due to a lack of insulin. Option B is incorrect because while Type II diabetes is more common and often preventable through lifestyle changes, it is not solely genetic. Option C is incorrect because Type I diabetes, not Type II, is characterized by fasting hyperglycemia due to an absolute lack of insulin production.

5. Inadequate intake of vitamin A occurs in lower socioeconomic groups due to a lack of resources to purchase and consume vegetables and fruits.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. Inadequate intake of vitamin A in lower socioeconomic groups is due to a lack of resources to purchase and consume vegetables and fruits. This is supported by the fact that the average intake in the United States meets the Recommended Dietary Allowance (RDA) for vitamin A intake, except in lower socioeconomic groups. These individuals often lack the financial means to buy, prepare, and eat a variety of fruits and vegetables, leading to deficiencies. It's important to note that because vitamin A can be stored in the liver, most adults have sufficient quantities to maintain health. Choices B, C, and D are incorrect because the statement and reason are both accurate and logically connected, as the lack of resources directly impacts the ability to obtain necessary sources of vitamin A.
