1. Digestible carbs are absorbed as ___ through the small intestinal wall and are delivered to the liver, which releases ___ into the bloodstream.

• A. glucose
• B. monosaccharides
• C. galactose
• D. disaccharides

Correct answer: B

Rationale: Digestible carbohydrates are absorbed as monosaccharides (simple sugars) like glucose, which the liver can release into the bloodstream for energy.

2. Which vitamin is primarily obtained from sunlight exposure?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D is synthesized in the skin when it is exposed to sunlight. This process allows the body to produce Vitamin D naturally. Vitamin A (Choice A) is found in foods like liver and carrots and is not primarily obtained from sunlight. Vitamin C (Choice B) is commonly found in fruits and vegetables. Vitamin E (Choice D) is present in foods like nuts and seeds and is not primarily obtained from sunlight.

3. A nurse is teaching a client about strategies to prevent constipation. Which of the following statements by the client indicates an understanding of the teaching?

• A. Drinking four to five glasses of water per day will prevent constipation.
• B. I should consume mineral oil once per day.
• C. Eating foods high in fiber will make elimination easier.
• D. I can skip a meal if I feel bloated.

Correct answer: C

Rationale: The correct answer is C. Eating foods high in fiber increases stool bulk and promotes easier elimination, thus preventing constipation. Choices A, B, and D are incorrect. Drinking water is important, but the emphasis should be on high-fiber foods. Mineral oil is not a recommended first-line treatment for constipation, and skipping meals can disrupt regular bowel movements, potentially leading to constipation.

4. Are the following statements both true: 'Most excess energy intake, whether from protein, carbohydrate, alcohol, or fat, is stored in the liver' and 'Fat is a good source of energy, but the preferred fuel is protein'?

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

Correct answer: B

Rationale: Both of the given statements are false. The first statement is inaccurate because the primary location for excess energy storage is not the liver, but rather adipose tissue where it is stored as fat. While the liver does have a role in energy storage and metabolism, it is not the main storage site for excess intake. The second statement is also incorrect. Although fat and protein can be used as sources of energy, the body's preferred source of energy is carbohydrates. They break down more efficiently and are easier for the body to use. The body prefers to conserve protein for other essential functions, such as tissue repair and the production of enzymes. Therefore, protein is not the preferred fuel source.

5. 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.
