1. Which of the following foods or beverages would offer the most nutrients per calorie?

A. chicken
B. wine
C. white bread
D. broccoli

Correct answer: D

Rationale: Broccoli is indeed the correct answer. Broccoli is considered nutrient-dense, meaning it provides a significant amount of essential nutrients like vitamins, minerals, and fiber while being relatively low in calories. On the other hand, choices A, B, and C are not as nutrient-dense as broccoli. Chicken can be nutritious but may vary in nutrient content depending on the cut and preparation method. Wine, although containing antioxidants like resveratrol, is not a significant source of essential nutrients. White bread is often low in nutrients and fiber compared to whole grain options, making it less nutrient-dense than broccoli.

2. 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.

3. Persons experiencing crisis becomes passive and submissive. As a nurse, you know that the best approach in crisis intervention is to be:

A. Active and Directive
B. Passive friendliness
C. Active friendliness
D. Firm kindness

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.
