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

• A. 5
• B. 5.5
• C. 6
• D. 6.5

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.

2. Which of the following categories identifies the focus of community/public health nursing practice?

• A. Promoting and maintaining the health of populations and preventing and minimizing the progress of disease
• B. Rehabilitation and restorative services
• C. Adaptation of hospital care to the home environment
• D. Hospice care delivery

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.

3. Which set of guidelines is intended to assess nutrient adequacy or plan intakes of population groups, not individuals?

• A. Old Recommended Dietary Allowances (RDA)
• B. Estimated Average Requirement (EAR)
• C. New Recommended Dietary Allowances (RDA)
• D. Tolerable Upper Intake Level (UL)

Correct answer: B

Rationale: The Estimated Average Requirement (EAR) is specifically designed to assess nutrient adequacy or plan intakes for population groups, not for individuals. The Old and New Recommended Dietary Allowances (RDA) are meant for individuals, not groups, as they provide guidelines for specific nutrient intake levels for healthy individuals. The Tolerable Upper Intake Level (UL) is used to set the highest level of nutrient intake that is likely to pose no risk of adverse health effects for most individuals in a group, which is different from assessing nutrient adequacy for groups.

4. Which type of bath would you recommend for a patient experiencing pruritus?

• A. Saline
• B. Colloidal (oatmeal)
• C. Water
• D. Sodium bicarbonate

Correct answer: B

Rationale: The best choice for a pruritus (itching) patient is a colloidal (oatmeal) bath, as it is known for its soothing effect on itchy, irritated skin. Saline, water, and sodium bicarbonate baths may not provide the same level of relief for pruritus. The nursing care should involve comprehensive assessments and appropriate interventions to optimize patient outcomes. In this case, a colloidal bath is the most suitable intervention for a patient experiencing pruritus.

5. Which of the following amino acids are considered indispensable?

• A. Lysine
• B. Methionine
• C. Tryptophan
• D. Valine

Correct answer: A

Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.
