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. Overdosage of medication or anesthetic can happen even with the aid of technology like infusion pumps, sphygmomanometer, and similar devices/machines. As a staff member, how can you improve the safety of using infusion pumps?

• A. Check the functionality of the pump before use
• B. Select the brand of infusion pump carefully
• C. Allow the technician to set the infusion pump before use
• D. Verify the flow rate against your calculation

Correct answer: D

Rationale: To enhance the safety of using infusion pumps, it is crucial to verify the flow rate against your calculation. This step ensures that the prescribed dosage is being delivered accurately, reducing the risk of medication errors. Checking the functionality of the pump before use (Choice A) is also important to ensure it is working properly. Allowing the technician to set the pump (Choice C) may not always guarantee the correct settings. Selecting the brand of infusion pump carefully (Choice B) is not directly related to the safe use of the pump.

3. Which of the following foods provides the most protein?

• A. Beans
• B. Red peppers
• C. Asparagus
• D. Celery

Correct answer: A

Rationale: The correct answer is 'Beans.' Beans are a rich source of plant-based protein, making them the best option among the listed foods for protein content. Red peppers, asparagus, and celery are not significant sources of protein compared to beans, hence they are incorrect choices for this question.

4. Each statement is true of rickets, except one. Which is the exception?

• A. Rickets is being diagnosed more frequently in the United States.
• B. Rickets is caused by vitamin C deficiency.
• C. Tachetic deformities such as bow legs or knock-knees develop.
• D. A narrow and distorted chest occurs.

Correct answer: B

Rationale: Rickets is caused by vitamin D deficiency, not vitamin C deficiency. It usually occurs in children who are 1 to 3 years old. The name rickets came from the word 'wrikken,' meaning 'to bend or twist.' Common manifestations of rickets include tachetic deformities like bow legs or knock-knees, a narrow and distorted chest, and failure of the epiphyses of bones to develop normally, resulting in twisted and warped bones. While the diagnosis of rickets may be increasing in the United States, it is not caused by a lack of vitamin C.

5. Which mental health disorder can lead to the erosion of lingual enamel, enlarged parotid glands, palatal bruising, and dentinal hypersensitivity?

• A. Bulimia
• B. Anorexia nervosa
• C. Depression
• D. Schizophrenia

Correct answer: A

Rationale: The correct answer is A: Bulimia. Bulimia involves repeated episodes of binge eating followed by purging, which can lead to the erosion of lingual enamel, enlarged parotid glands, palatal bruising, and dentinal hypersensitivity. This behavior exposes the teeth to stomach acid during purging, causing damage to the enamel. Choices B, C, and D are incorrect because these conditions are not typically associated with the specific oral health issues mentioned in the question.
