1. Riboflavin

A. Vitamin B1
B. Vitamin B2
C. Vitamin B3
D. Vitamin B12

Correct answer: B

Rationale: Riboflavin is also known as Vitamin B2, which is important for energy production and the metabolism of fats, drugs, and steroids.

2. Is it correct that eliminating sucrose from the diet leads to a significant reduction in dental caries, and that the best advice is to consume sugar in moderation and limit the frequency of sugar exposure?

A. Both statements are true
B. Both statements are false
C. The first statement is true; the second is false
D. The first statement is false; the second is true

Correct answer: D

Rationale: The first statement is incorrect because dental caries are not solely caused by sucrose. They are the result of a complex interaction of multiple factors, including the type of bacteria in the mouth, the host's diet, oral hygiene, and salivary flow. The second statement is correct as consuming sugar in moderation and limiting the frequency of sugar exposure are indeed effective strategies to prevent dental caries. Therefore, the answer is option D: The first statement is false; the second is true.

3. A client has a small-bore jejunostomy and is receiving a continuous tube feeding with a high-viscosity formula. Which of the following actions should the nurse take to prevent the tubing from clogging?

A. Replace the bag and tubing every 24 hours
B. Flush the tubing with 10 mL water every 6 hours
C. Administer the feeding by gravity drip
D. Heat the formula prior to infusion

Correct answer: B

Rationale: To prevent clogging when using high-viscosity formulas in a small-bore jejunostomy, the nurse should flush the tubing with 10 mL of water every 6 hours. This action helps maintain tube patency and prevent blockages. Replacing the bag and tubing every 24 hours (Choice A) is unnecessary and does not specifically address preventing clogging. Administering the feeding by gravity drip (Choice C) or heating the formula prior to infusion (Choice D) are not effective interventions for preventing tubing clogging.

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

A. Menopause
B. Age older than 35
C. Increased levels of arachidonic acid
D. Elevated HDL cholesterol

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.
