1. How many calories are contained in a food that has 15 grams of carbohydrates, 4 grams of protein, and 10 grams of fat?

• A. 106
• B. 124
• C. 166
• D. 202

Correct Answer: C: 166

Rationale: To calculate the total calories in a food item, you can use the following conversions: every 1 gram of carbohydrate provides 4 calories, 1 gram of protein provides 4 calories, and 1 gram of fat provides 9 calories. Therefore, for this food item, multiply 15 grams of carbohydrates by 4 calories/gram, 4 grams of protein by 4 calories/gram, and 10 grams of fat by 9 calories/gram. The calculation would be (15 * 4) + (4 * 4) + (10 * 9) = 60 + 16 + 90 = 166 calories. Choice A (106) is incorrect because it does not consider the calories from fat. Choice B (124) is incorrect as it underestimates the calories by not including all macronutrients. Choice D (202) is incorrect as it overestimates the calories by adding up the values incorrectly.

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: Chicken

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. A client who is postoperative following a liver transplant and weighs 65 kg. Which of the following actions should the nurse plan to take?

• A. Keep the client NPO for the first week postoperative.
• B. Limit caloric content once the client resumes eating.
• C. Stress the importance of safe food-handling practices.
• D. Decrease foods high in carbohydrates once the client resumes eating.

Correct Answer: Stress the importance of safe food-handling practices.

Rationale: After a liver transplant, it is crucial to stress the importance of safe food-handling practices to prevent foodborne illnesses, especially due to the client's altered immune system. Keeping the client NPO for the first week postoperative is not recommended as early nutrition support is essential for recovery. Limiting caloric content once the client resumes eating may not be appropriate as they need adequate nutrition for healing. Decreasing foods high in carbohydrates without a specific indication may lead to inadequate nutrient intake, which is not ideal for the client's recovery.

4. A nurse is providing teaching to the parent of a toddler about appropriate snacks. Which of the following foods should the nurse include?

• A. Sliced bananas
• B. Raw celery
• C. Peanut butter
• D. Grapes

Correct Answer: Sliced bananas

Rationale: The correct answer is sliced bananas. Bananas are a good choice for toddlers as they are easy to chew, rich in potassium, and generally well-tolerated. Raw celery (Choice B) may pose a choking hazard due to its fibrous nature. Peanut butter (Choice C) should be avoided as it can also be a choking hazard and may cause an allergic reaction in some children. Grapes (Choice D) are a choking hazard for toddlers due to their size and shape, so they should be cut into smaller pieces or avoided altogether.

5. A nurse is caring for an antepartum client who has iron-deficiency anemia. When teaching the client about nutrition, the nurse should emphasize the need for an increased intake of which of the following foods?

• A. Milk and cheese
• B. Red meat and organ meat
• C. Fresh fruits
• D. Whole grain breads

Correct Answer: Red meat and organ meat

Rationale: The correct answer is red meat and organ meat. These foods are rich sources of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Red meat and organ meat can significantly help in increasing the iron levels in individuals with iron-deficiency anemia, especially in antepartum clients. Fresh fruits, while nutritious, do not provide high amounts of iron. Milk and cheese are not the best sources of iron for individuals with iron-deficiency anemia. Whole grain breads also do not contain as much bioavailable iron as red meat and organ meat.
