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. Nurse DMLM is correct in identifying the correct sequence of events during abdominal assessment if she identifies which of the following?

• A. Inspection, Auscultation, Percussion, Palpation
• B. Inspection, Percussion, Palpation, Auscultation
• C. Inspection, Palpation, Percussion, Auscultation
• D. Inspection, Auscultation, Palpation, Percussion

Correct answer: D

Rationale: The correct sequence for abdominal assessment is Inspection, Auscultation, Percussion, Palpation. Start with Inspection to observe any visible abnormalities, followed by Auscultation to listen for bowel sounds, then Percussion to assess the density of underlying structures, and finally Palpation to feel for any tenderness or masses. Choices A, B, and C have the incorrect sequence of assessment techniques.

3. A nurse is completing an admission assessment on an adolescent client who is vegan. Which breakfast item should the nurse recommend as a protein combination with their diet restriction?

• A. Bagel with cream cheese
• B. Wheat toast with jelly
• C. Oatmeal pancakes with peanut butter
• D. Eggs with tofu bacon

Correct answer: C

Rationale: The correct answer is C: Oatmeal pancakes with peanut butter. For a vegan client, it is important to recommend plant-based protein sources. Oatmeal pancakes with peanut butter offer a good protein combination that aligns with their dietary restriction. Choices A, B, and D are not suitable as they all contain animal-derived products, which are not suitable for a vegan diet.

4. What is the purpose of a chest tube after a lobectomy procedure, as understood by the nurse?

• A. Prevent mediastinal shift
• B. Promote chest expansion of the remaining lung
• C. Drain fluids and blood accumulated post-operatively
• D. Remove the air in the lungs to promote lung expansion

Correct answer: C

Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.

5. What is the digestive action of bile?

• A. It breaks down carbohydrates
• B. It breaks down proteins
• C. It breaks down lipids
• D. It aids in fat digestion

Correct answer: D

Rationale: Bile, which is produced by the liver and stored in the gallbladder, aids in the digestion of fats. It does this by emulsifying the fats, which makes them easier for the digestive enzymes, such as lipase, to break down. While choices A, B, and C could be seen as partially correct since fats are a type of lipid and the process of breaking down fats could be seen as breaking down lipids, the most accurate answer is D, as the primary function of bile is to aid in fat digestion, not the digestion of all types of lipids or the digestion of proteins or carbohydrates.
