Correct Answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.

Correct Answer: B

Rationale: The correct answer is B: Emulsify fats in the small intestine. Bile emulsifies fats in the small intestine, breaking them down into smaller droplets that can be more easily digested by enzymes like lipase. Choice A is incorrect as fats are not digested in the stomach but rather in the small intestine. Choice C is incorrect as fats are transported through the lymphatic system instead of the circulatory system. Choice D is incorrect as fats are broken down into smaller components through emulsification, not splitting.

Correct Answer: C

Rationale: The correct answer is C. The first statement is true; retentive carbohydrates promote bacterial growth and plaque formation. However, the second statement is false; gingivitis is not irreversible and is often reversible with proper care. Gingivitis is the inflammation of the gums due to plaque buildup and poor oral hygiene. With good oral hygiene practices and professional dental care, gingivitis can be reversed. The other choices are incorrect because gingivitis is not irreversible, making statement two false.

Correct Answer: A

Rationale: Excessive supplementation of calcium and vitamin D beyond the upper intake level is not recommended unless under medical supervision, as it can cause adverse health effects.

Correct Answer: D

Rationale: The correct answer is D, conducting nutrition assessments. Registered dietitians are responsible for assessing an individual's nutritional status, dietary intake, and health needs. This assessment forms the basis for developing personalized nutrition care plans. Choices A and B involve the administration of specialized nutrition support, which is typically done by healthcare providers with specific training in those areas. Choice C, prescribing diet orders, may fall outside the scope of practice for a dietitian as they focus more on assessment, education, and counseling related to nutrition rather than prescribing medical treatments.
