1. Which nutrient is most important for the prevention of osteoporosis?

• A. Vitamin A
• B. Iron
• C. Calcium
• D. Protein

Correct answer: C

Rationale: Calcium is the most important nutrient for bone health and the prevention of osteoporosis. Calcium plays a crucial role in maintaining bone density and strength. Vitamin A is important for vision and immune function but is not directly related to bone health. Iron is essential for oxygen transport in the blood, while protein is important for muscle growth and repair. However, in the context of preventing osteoporosis, calcium is the key nutrient.

2. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?

• A. Spinach
• B. Cantaloupe
• C. Chicken
• D. Lentils

Correct answer: C

Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.

3. What is the function of villi and microvilli in the GI tract?

• A. produce bile
• B. kill bacteria
• C. produce vitamin K
• D. increase the surface area for absorption

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

4. A nurse provides discharge instructions to a client about the food items that interact with warfarin effectiveness. Which food item indicates that the teaching was effective?

• A. Cauliflower
• B. Zucchini
• C. Green beans
• D. Broccoli

Correct answer: A

Rationale: Cauliflower is high in vitamin K, which can interact with warfarin.

5. When assessing for criteria that signify malnutrition risk, which element would most likely be included as part of the functional assessment data?

• A. severity of illness
• B. presence of pressure sores
• C. localized edema
• D. generalized weakness

Correct answer: D

Rationale: Generalized weakness is a key indicator of malnutrition and is often assessed as part of functional status, reflecting muscle wasting and reduced physical function. The other choices, such as severity of illness, presence of pressure sores, and localized edema, are important factors to consider in a clinical assessment but are not primarily indicative of malnutrition risk. Generalized weakness directly relates to the functional impact of malnutrition on physical performance.
