1. Which of the following statements is false?

• A. People with a vitamin K deficiency experience increased clotting time
• B. The major function of vitamin E is promoting vision
• C. Vitamin D functions as a hormone
• D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash

Correct answer: B

Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.

2. Lynn is an older adult who lives alone and has requested advice on how to eat a nutritious diet as cheaply as possible. One useful, practical tip for Lynn might be to _____.

• A. buy just a few pieces of fresh fruit at a time, in different stages of ripeness
• B. choose small boxes of frozen vegetables instead of large bags
• C. purchase pre-sliced or shredded cheese rather than whole pieces
• D. avoid buying certain foods in bulk, such as beans or dried legumes

Correct answer: A

Rationale: Buying a few pieces of fresh fruit at different stages of ripeness ensures that Lynn will have ripe fruit available over several days, reducing waste and cost. Choice B focuses on frozen vegetables but doesn't address the variety and ripeness factor like Choice A. Choice C is about cheese, which may not be as essential for a nutritious diet compared to fresh fruit. Choice D suggests avoiding certain foods in bulk, which might not be as relevant for maintaining a nutritious diet economically as the strategy in Choice A.

3. A patient who is recovering from surgery should increase their intake of which nutrient to promote healing?

• A. Fats
• B. Carbohydrates
• C. Protein
• D. Fiber

Correct answer: C

Rationale: Protein is crucial for tissue repair and recovery after surgery. Proteins provide the building blocks necessary for tissue healing and regeneration. Fats are important for various bodily functions but are not as directly involved in tissue repair as proteins. Carbohydrates provide energy but do not play a primary role in tissue healing. Fiber is essential for digestive health but is not a nutrient that directly promotes tissue repair.

4. A nurse is caring for a client who has cancer and is receiving total parenteral nutrition (TPN). Which of the following lab values indicates the treatment is effective?

• A. Hct 43%
• B. WBC 8,000/uL
• C. Albumin 4.2 g/dL
• D. Calcium 9.4 mg/dL

Correct answer: C

Rationale: The correct answer is Albumin 4.2 g/dL. Albumin is a protein produced by the liver and is a key indicator of nutritional status. In a client receiving total parenteral nutrition (TPN), an increase in albumin level indicates that the treatment is effective in providing adequate nutrition support. Hct (hematocrit), WBC (white blood cell count), and calcium levels are not direct indicators of the effectiveness of TPN in this context.

5. A woman who has been following a vegan diet may need ____ supplements.

• A. vitamin C and vitamin A
• B. vitamin D and vitamin B12
• C. vitamin E and K
• D. vitamin D and niacin

Correct answer: B

Rationale: The correct answer is B: vitamin D and vitamin B12. Vegans may need to supplement vitamin D and B12 as these nutrients are mainly found in animal products. While choices A, C, and D are essential vitamins, they are not typically lacking in a vegan diet. Vitamin C can be obtained from various plant sources, vitamin A can be derived from beta-carotene in plants, and vitamin E and K are also found in plant-based foods. Niacin, although important, can be sourced from plant-based sources and is not a common deficiency in vegan diets.
