1. Match protease with its digestive action:

Correct answer: B

Rationale: Proteases are enzymes that break down proteins into smaller peptides and amino acids.

2. Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?

Correct answer: B

Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.

3. What type of drug is lamivudine, used for the management of HIV infection?

Correct answer: C

Rationale: Lamivudine belongs to the class of nucleoside reverse transcriptase inhibitors (NRTIs), making choice C the correct answer. NRTIs like lamivudine work by inhibiting the reverse transcriptase enzyme, an essential component for the HIV virus to replicate. Choices A, B, and D are incorrect because lamivudine does not function as a CCR5 antagonist, fusion inhibitor, or protease inhibitor in the management of HIV infection.

4. What is the main function of dietary fiber in managing cholesterol levels?

Correct answer: D

Rationale: Dietary fiber helps lower cholesterol levels by binding to bile acids and reducing cholesterol absorption.

5. A client with a large lower-leg ulcer needs protein for wound healing. Which of the following foods should the nurse suggest?

Correct answer: B

Rationale: Grilled salmon is the best choice for providing high-quality protein for wound healing. Salmon is rich in essential amino acids, omega-3 fatty acids, and vitamin D, which can help promote tissue repair and reduce inflammation. Kidney beans, peanut butter, and raw spinach are good protein sources but do not offer the same level of high-quality protein and nutrients needed specifically for wound healing.
