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. One of the most common factors that compromise the vitamin D status of older adults, particularly those living in assisted living communities is _____.

• A. decreased intake of fruits and vegetables
• B. lack of physical activity
• C. malabsorption due to atrophic gastritis
• D. lack of exposure to sunlight

Correct answer: D

Rationale: The correct answer is 'D: lack of exposure to sunlight.' Older adults, especially those in assisted living communities, are at risk of vitamin D deficiency due to spending most of their time indoors, which reduces their exposure to sunlight. Sunlight is essential for the body to produce vitamin D. Choices A, B, and C are less likely to be major factors in compromising vitamin D status. While a decreased intake of fruits and vegetables and lack of physical activity can impact overall health, they are not as directly related to vitamin D status. Malabsorption due to atrophic gastritis may affect the absorption of certain nutrients, but vitamin D synthesis primarily depends on sunlight exposure.

3. Which vitamin acts most like a hormone?

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

Correct answer: C

Rationale: The correct answer is Vitamin D. Although vitamin D, also known as calciferol, has been called a vitamin, it is more appropriately classified as a hormone. Like hormones, vitamin D acts to control the function of other cell types. For example, it helps the body absorb and regulate skeletal calcium and phosphorus levels. Choice A (Vitamin A) plays a crucial role in vision and immune function. Choice B (Vitamin B) is a complex of different vitamins that play various roles in the body. Choice D (Vitamin C) is important for collagen production and acts as an antioxidant.

4. A healthcare provider is providing teaching about nutrition to a group of clients. The healthcare provider should include that which of the following foods contains the highest level of thiamine per serving?

• A. 1 hard-boiled egg
• B. 1 cup dried pears
• C. 1 cup whole grain wheat flour
• D. 1 cup Brussels sprouts

Correct answer: C

Rationale: Whole grain wheat flour contains the highest level of thiamine per serving compared to the other options provided. Thiamine, also known as Vitamin B1, is essential for energy metabolism. While eggs, dried pears, and Brussels sprouts are nutritious foods, they do not contain as high a level of thiamine as whole grain wheat flour. Therefore, the correct choice is whole grain wheat flour in this case.

5. Select all that apply. Which of the following oils contain high levels of unsaturated fatty acids and low levels of saturated and trans fats?

• A. vegetable oil
• B. palm oil
• C. coconut oil
• D. canola oil

Correct answer: A

Rationale: Vegetable, canola, and olive oils are high in unsaturated fats and low in saturated and trans fats, making them heart-healthy choices.
