• A. Provide energy
• B. Support muscle growth
• C. Neutralize free radicals
• D. Increase blood sugar

Correct answer: C

Rationale: The primary function of antioxidants in the diet is to neutralize free radicals. Free radicals can cause cellular damage, leading to various chronic diseases. Antioxidants help combat this oxidative stress by neutralizing free radicals. Choices A, B, and D are incorrect because antioxidants do not provide energy, support muscle growth, or increase blood sugar; their main role is in combating oxidative stress.

2. Salome was fitted a hearing aid. She understood the proper use and wear of this device when she says that the battery should be functional, the device is turned on and adjusted to a:

• A. therapeutic level
• B. comfortable level
• C. prescribed level
• D. audible level

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

3. A nurse at a provider's office is providing teaching to a client who is taking chemotherapy and losing weight. Which of the following should the nurse recommend to increase calorie and protein intake? (Select one that does not apply.)

• A. Top yogurt with fruits.
• B. Add cream to soups.
• C. Use milk instead of water in recipes.
• D. Increase fluids during meals.

Correct answer: D

Rationale: The correct recommendation to increase calorie and protein intake for a client taking chemotherapy and losing weight is to add cream to soups (choice B), as it provides additional calories and proteins. Using milk instead of water in recipes (choice C) can also increase the calorie and protein content. Topping yogurt with fruits (choice A) can be a healthy choice but may not significantly increase calorie and protein intake. Increasing fluids during meals (choice D) may fill up the stomach, potentially reducing the intake of solid foods, which is not ideal when trying to increase calorie and protein consumption.

4. The dietary guidelines for Americans recommend consuming:

• A. nutrient dense foods
• B. non-essential amino acids
• C. energy dense foods
• D. organically grown foods

Rationale: The guidelines emphasize nutrient-dense foods that provide essential vitamins, minerals, and other nutrients without excessive calories, sugars, or unhealthy fats.

5. Which item is typically fortified with iodine to address iodine deficiency in the population?

• A. Flour
• B. Salt
• C. Canned vegetables
• D. Drinking water

Correct answer: B

Rationale: Iodized salt is the correct answer. Iodine deficiency can lead to thyroid problems, so iodine is added to salt to ensure an adequate intake of this essential nutrient. Flour is often fortified with other nutrients like folic acid, iron, and niacin, but not iodine. Canned vegetables and drinking water are not typically fortified with iodine to address deficiency in the population.
