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 type of nutritional deficiency results from inadequate absorption?

• A. Unmeasurable
• B. Primary deficiency
• C. Secondary deficiency
• D. Codependent

Correct answer: C

Rationale: The correct answer is C: Secondary deficiency. A nutritional deficiency resulting from decreased intake is called a primary deficiency. On the other hand, a secondary deficiency refers to a vitamin deficiency caused by inadequate absorption or use, increased requirements, excretion, or destruction. Choice A, 'Unmeasurable,' is incorrect as it does not describe a type of nutritional deficiency. Choice B, 'Primary deficiency,' is incorrect as it refers to a deficiency caused by decreased intake, not inadequate absorption. Choice D, 'Codependent,' is incorrect as it is unrelated to the context of nutritional deficiencies.

3. You will give health instructions to Carlo, a case of bronchial asthma. The health instruction will include the following, EXCEPT:

• A. Avoid emotional stress and extreme temperature
• B. Avoid pollution like smoking
• C. Avoid pollens, dust, seafood
• D. Practice respiratory isolation

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. Overdosage of medication or anesthetic can happen even with the aid of technology like infusion pumps, sphygmomanometer, and similar devices/machines. As a staff member, how can you improve the safety of using infusion pumps?

• A. Check the functionality of the pump before use
• B. Select the brand of infusion pump carefully
• C. Allow the technician to set the infusion pump before use
• D. Verify the flow rate against your calculation

Correct answer: D

Rationale: To enhance the safety of using infusion pumps, it is crucial to verify the flow rate against your calculation. This step ensures that the prescribed dosage is being delivered accurately, reducing the risk of medication errors. Checking the functionality of the pump before use (Choice A) is also important to ensure it is working properly. Allowing the technician to set the pump (Choice C) may not always guarantee the correct settings. Selecting the brand of infusion pump carefully (Choice B) is not directly related to the safe use of the pump.

5. Which of the following interventions should be considered the highest priority when caring for June, who has hemiparesis secondary to a stroke?

• A. Position June in an upright lateral position
• B. Perform range of motion exercises
• C. Apply antiembolic stockings
• D. Use hand rolls or pillows for support

Correct answer: C

Rationale: The correct answer is C, 'Apply antiembolic stockings'. In the case of a patient who has experienced a stroke and is suffering from hemiparesis, the highest priority intervention is to prevent further complications such as deep vein thrombosis (DVT), which can be life-threatening. Antiembolic stockings are used to increase venous blood flow velocity and reduce the risk of DVT. Choice 'A', positioning June in an upright lateral position, while important for overall care, is not the highest priority. Choice 'B', performing range of motion exercises, is an important part of recovery but not the immediate priority. Choice 'D', using hand rolls or pillows for support, is also a valuable intervention but does not address the most pressing risk of further complications.
