1. What is the primary function of antioxidants in the diet?

• 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. Which of the following is a common sign of vitamin D deficiency?

• A. Brittle nails
• B. Muscle weakness
• C. Night blindness
• D. Hair loss

Correct answer: B

Rationale: Muscle weakness is a common sign of vitamin D deficiency. Vitamin D is essential for calcium absorption and bone health, and its deficiency can lead to muscle weakness. Brittle nails (Choice A) are not typically associated with vitamin D deficiency. Night blindness (Choice C) is related to vitamin A deficiency, not vitamin D deficiency. Hair loss (Choice D) can be linked to various factors, but it is not a common sign of vitamin D deficiency.

3. A healthcare professional has just inserted an NG tube for a client who is to start enteral tube feedings. Which of the following actions should the healthcare professional take to verify tube placement?

• A. Measure the tube length.
• B. Obtain an abdominal x-ray.
• C. Flush the tube with 20 mL of water.
• D. Auscultate the client’s lungs.

Correct answer: B

Rationale: Obtaining an abdominal x-ray is the most accurate method to verify the correct placement of an NG tube. Measuring the tube length is not a reliable method to confirm placement as it may vary among individuals. Flushing the tube with water and auscultating the client's lungs are not definitive methods to ensure proper NG tube placement.

• A. reorganization
• B. reorienting
• C. demineralizing
• D. remodeling

Rationale: The correct answer is D, 'remodeling.' Remodeling is the process by which bones continuously lose and gain minerals, maintaining bone strength and integrity over time. 'Reorganization' (choice A), 'reorienting' (choice B), and 'demineralizing' (choice C) do not accurately describe the process of bones continuously losing and gaining minerals.
