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. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.

• A. 4%
• B. 21%
• C. 34%
• D. 49%

Correct answer: B

Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.

3. The lobe of the brain that contains the auditory receptive areas is the ____________ lobe.

• A. temporal
• B. frontal
• C. parietal
• D. occipital

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.

4. During an initial visit with an older adult client living alone and having difficulty preparing meals, what should the home health nurse do first?

• A. Discuss nutritional requirements with the client.
• B. Refer the client to a senior citizen center.
• C. Arrange for a home-delivered meal program.
• D. Perform a nutrition screening.

Correct answer: D

Rationale: Performing a nutrition screening is the most appropriate action for the nurse to take first. This allows the nurse to assess the client's current nutritional status and identify any specific needs. Discussing nutritional requirements with the client (Choice A) may be important but should come after the initial assessment. Referring the client to a senior citizen center (Choice B) or arranging for a home-delivered meal program (Choice C) are actions that may be considered later based on the findings of the nutrition screening.

5. Discharge plans of diabetic clients include injection site rotation. You should emphasize that the space between sites should be:

• A. 6.0 cm.
• B. 5.0 cm.
• C. 2.5 cm.
• D. 4.0 cm.

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
