1. Cyanocobalamin is a form of which vitamin?

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

Correct answer: D

Rationale: Cyanocobalamin is a synthetic form of Vitamin B12. Vitamin B12 is essential for various bodily functions, including red blood cell formation, neurological function, and DNA synthesis. It is not to be confused with Vitamin B1, B2, or B3, which are separate vitamins with different roles in the body.

2. What is a major feature of the therapeutic lifestyle changes (TLC) recommended for the treatment of high blood cholesterol?

• A. Avoiding all foods that contain cholesterol
• B. Reducing sodium intake to less than 2 g/day
• C. Limiting total fat intake to less than 30% of energy intake
• D. Limiting saturated fat intake to less than 7% of energy intake

Correct answer: D

Rationale: The correct answer is D, 'Limiting saturated fat intake to less than 7% of energy intake.' This is a central feature of the therapeutic lifestyle changes (TLC) recommended for treating high blood cholesterol. Saturated fats can increase low-density lipoprotein (LDL) cholesterol, a significant risk factor for heart disease. Choice A is incorrect because while it is recommended to limit cholesterol intake, it's not suggested to avoid all foods containing cholesterol entirely in the TLC. Choice B is also incorrect as although reducing sodium intake is beneficial for controlling blood pressure, it's not specifically targeted in the TLC for managing high cholesterol. Lastly, while limiting total fat intake is a healthy guideline, it's not as specific or effective as limiting saturated fat intake, making choice C also incorrect.

3. Any disease that produces ____ malabsorption can bring about deficiencies of vitamins A, D, E, and K.

• A. water
• B. protein
• C. fat
• D. carbs

Correct answer: C

Rationale: Vitamins A, D, E, and K are fat-soluble, meaning they require fat for absorption. Diseases that cause fat malabsorption can lead to deficiencies in these vitamins.

4. Nutritional goals for a patient wishing to modify eating patterns should adhere to each, except one. Which is the exception?

• A. Measurable
• B. Immediate
• C. Realistic
• D. Achievable

Correct answer: B

Rationale: Nutritional goals should be measurable, realistic, and achievable. They should not be immediate, as sustainable changes take time.

5. In kidney disease, which mineral should a patient limit intake of?

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

Correct answer: C

Rationale: In kidney disease, patients are advised to limit the intake of phosphorus. High levels of phosphorus can be problematic as the kidneys may not be able to effectively filter it out, leading to bone health issues. Calcium (Choice A) is important for bone health, but its restriction is not typically necessary in kidney disease. Magnesium (Choice B) and potassium (Choice D) restrictions may be required in certain cases of kidney disease, but phosphorus is the mineral most commonly limited due to its impact on bone health.
