1. Fat-soluble vitamins are different from water-soluble vitamins because the body is able to store only small amounts of fat-soluble vitamins.

• 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: C

Rationale: The statement is correct, but the reason is not correct. A major difference between fat-soluble and water-soluble vitamins is that the body is able to store larger amounts of fat-soluble vitamins. Vitamins A and D are stored for long periods; therefore, minor shortages might not be identified until drastic depletion has occurred. Observable signs and symptoms of a dietary deficiency are often not identified until they are in an advanced state. Water-soluble vitamins, on the other hand, are not stored in the body and are excreted in the urine if taken in excess, making it harder to reach toxic levels.

2. Select all that apply. You are interested in learning about the effect of eating diet soft drinks on your health. Your internet search leads you to a website with the ending .com, which tells you that diet soft drinks contain sugar alcohols that can cause harm. Which of the following actions are logical?

• A. notice if there are any ads on the page that suggest conflicts of interest
• B. read about consuming diet soft drinks in the dietary guidelines for Americans
• C. visit a more credible website and compare information
• D. all of the above

Correct answer: D

Rationale: Logical steps include evaluating the credibility of the website, reading official guidelines, comparing information from credible sources, and verifying the author's qualifications.

3. What would you do to increase the amount of iron absorbed from a meal?

• A. Drink plenty of coffee before each meal
• B. Avoid eating foods rich in vitamin C with the meal
• C. Eat a calcium-rich food with the meal
• D. Consume orange juice as a beverage with a meal

Correct answer: D

Rationale: The correct answer is D: 'Consume orange juice as a beverage with a meal'. This is because Vitamin C significantly enhances the absorption of non-heme iron, a form of iron found in plant-based foods. Therefore, consuming orange juice, which is rich in vitamin C, with a meal can effectively increase iron absorption. On the contrary, choices A, B, and C are incorrect. Coffee (Choice A) contains polyphenols that can inhibit iron absorption. Avoiding vitamin C-rich foods (Choice B) would decrease iron absorption, not increase it. While calcium (Choice C) is essential for many bodily processes, it can actually inhibit iron absorption when consumed together.

4. Almost all (99%) of the calcium in the body is used for?

• A. regulating the transmission of nerve impulses
• B. providing energy for cells
• C. providing rigidity for the bones
• D. regulating muscle contraction

Correct answer: C

Rationale: The correct answer is C: providing rigidity for the bones. Almost all of the calcium in the body is utilized for maintaining the strength and structure of bones and teeth. Calcium plays a crucial role in skeletal health by providing rigidity and support to the skeletal system. Choices A, B, and D are incorrect because while calcium is essential for various physiological functions like nerve transmission, cell energy production, and muscle contraction, the majority of calcium in the body is primarily allocated for bone health.

5. Amy is a 68-year-old patient who has rheumatoid arthritis affecting her hands and feet. Which substance has been shown to reduce joint tenderness and improve mobility in some people with this type of arthritis?

• A. Alfalfa Tea
• B. Cod Liver Oil
• C. Lecithin
• D. Fish Oil

Correct answer: D

Rationale: Fish oil has been identified as a substance that can help reduce joint tenderness and improve mobility in individuals with rheumatoid arthritis, as it is rich in omega-3 fatty acids. Omega-3 fatty acids have anti-inflammatory properties that can help alleviate the symptoms of rheumatoid arthritis. On the other hand, while Alfalfa Tea, Cod Liver Oil, and Lecithin have various health benefits, there isn't substantial evidence to suggest that they can improve conditions associated with rheumatoid arthritis.
