1. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?

• A. Longer exposure leads to an increased risk of demineralization
• B. Longer exposure increases the opportunity for remineralization
• C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
• D. The critical pH at which enamel decalcification occurs is 5.5 or less

Correct answer: B

Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.

2. A nurse is planning teaching for the parents of a toddler who follows a vegetarian diet. The nurse should plan to include which of the following foods as the best source of dietary protein for the child?

• A. Soy milk
• B. Peanut butter
• C. Dried beans
• D. Whole grains

Correct answer: C

Rationale: Dried beans are the best source of dietary protein for a toddler following a vegetarian diet. They are rich in protein and other essential nutrients. Soy milk, while a good source of protein, may not provide as much protein density as dried beans. Peanut butter is a good source of protein but may not be as protein-dense as dried beans. Whole grains are not as high in protein content compared to dried beans, making them a less optimal choice for meeting the toddler's protein needs.

3. For patients with hypertension, which dietary change is most recommended?

• A. Increase salt intake
• B. Reduce fiber intake
• C. Increase potassium intake
• D. Reduce sugar intake

Correct answer: C

Rationale: Increasing potassium intake can help reduce blood pressure in hypertensive patients.

4. What goal should an overweight woman include in her lifestyle for a healthy pregnancy?

• A. Aim to lose 11 to 20 pounds during pregnancy
• B. Increase protein intake to 35% of total calories
• C. Delay weight loss until after pregnancy
• D. Increase daily energy intake by 550 calories

Correct answer: C

Rationale: The healthiest approach for an overweight pregnant woman is to delay weight loss until after pregnancy. During pregnancy, the body needs sufficient nutrition and energy to support the growth and development of the baby. Attempting to lose weight during pregnancy, especially significant amounts, may compromise the health of both the mother and the baby. Increasing protein intake to 35% of total calories or energy intake by 550 calories per day without professional guidance may lead to an unbalanced diet, which is not optimal for pregnancy. The focus should be on maintaining a balanced, nutrient-rich diet and appropriate weight gain during pregnancy.

5. In consideration of the steps in applying the bag technique, which side of the paper lining of the CHN bag is considered clean to make a non-contaminated work area?

• A. The lower lip
• B. The outer surface
• C. The upper tip
• D. The inside surface

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
