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

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. Which factor has been shown to increase the risk of development of atherosclerosis?

Correct answer: A

Rationale: The correct answer is A: Menopause. Menopause is associated with an increased risk of atherosclerosis due to hormonal changes that affect lipid profiles and vascular health. Conversely, B: Age older than 35 is not necessarily a risk factor for atherosclerosis on its own, though atherosclerosis risk does generally increase with age. C: Increased levels of arachidonic acid is not specifically linked to atherosclerosis; it's a fatty acid that can be both beneficial and harmful to health depending on its metabolic pathway. D: Elevated HDL cholesterol is actually beneficial rather than harmful because HDL cholesterol is known as 'good' cholesterol that helps to reduce the risk of heart disease and atherosclerosis.

3. Transmission of HIV from an infected individual to another person occurs:

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. Nonnutritive sweeteners are not metabolized by microorganisms and do not promote dental caries. Products made with a nonnutritive sweetener can be used as frequently as 8 to 10 times per day.

Correct answer: C

Rationale: The first statement is true; nonnutritive sweeteners do not promote caries. However, the second statement is false because products with nonnutritive sweeteners should still be consumed in moderation.

5. A patient with an ileostomy is suffering from frequent diarrhea. The clinician should advise the patient to increase his intake of what food to thicken stool output?

Correct answer: C

Rationale: Potatoes are starchy and can help thicken stool output, making them beneficial for patients with an ileostomy experiencing diarrhea.
