1. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.

2. Fatty acids may differ from one another:

• A. in chain length
• B. in degree of saturation
• C. in number of calories
• D.

Correct answer: D

Rationale: Fatty acids vary in chain length and degree of saturation, affecting their physical properties and health effects.

3. 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.

4. Which food items should be consumed with nonheme iron to increase its absorption, according to a nurse's education plan for clients?

• A. Kiwi
• B. Strawberries
• C. Coffee
• D. Kiwi and Strawberries

Correct answer: D

Rationale: The correct answer is D: Kiwi and Strawberries. Both of these fruits are high in vitamin C, a nutrient known to enhance the absorption of nonheme iron. Vitamin C facilitates the conversion of nonheme iron into a form that is more readily absorbed by the body, thereby enhancing iron intake. In contrast, coffee (Choice C) contains certain compounds that can actually inhibit the absorption of iron, making it a less desirable choice when the goal is to increase iron absorption. Consequently, Choices A (Kiwi), B (Strawberries), and C (Coffee) were specifically picked to highlight the varying effects of different food items on nonheme iron absorption.

5. After consuming a meal high in fat, the _____ releases _______ to aid in digestion.

• A. stomach, acid
• B. liver, bile
• C. pancreas, bicarbonate
• D. gallbladder, bile

Correct answer: D

Rationale: The gallbladder releases bile into the small intestine to help digest fats. Bile emulsifies fats, breaking them down into smaller droplets for easier digestion. The stomach primarily releases gastric acid, the liver produces bile but stores it in the gallbladder, and the pancreas secretes bicarbonate to neutralize stomach acid in the small intestine. Therefore, choices A, B, and C are incorrect.
