Nursing Elites

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. A nurse is providing discharge teaching for a client who has acute pancreatitis and has a prescription for fat-soluble vitamin supplements. The nurse should instruct the client to take a supplement for which of the following?

• A. Vitamin A
• B. Vitamin B1
• C. Vitamin C
• D. Vitamin B12

Correct answer: A

Rationale: In acute pancreatitis, malabsorption of fat-soluble vitamins can occur due to pancreatic enzyme insufficiency. Vitamin A is a fat-soluble vitamin that may need supplementation in this case. Vitamin B1 (thiamine), Vitamin C, and Vitamin B12 are water-soluble vitamins and are not typically affected by pancreatic enzyme insufficiency in acute pancreatitis. Therefore, the correct supplement for the client with acute pancreatitis is Vitamin A.

3. All of the following are contraindications when giving Immunization except:

• A. BCG Vaccine can be given to a child with AIDS
• B. BCG Vaccine can be given to a child with Hepatitis B
• C. DPT can be given to a child that had convulsion 3 days after being given the first DPT dose
• D. DPT can be given to a child with active convulsion or other neurological disease

Correct answer: B

Rationale: The correct answer is B. BCG vaccine can be given to a child with Hepatitis B, as there is no contraindication for this. Choice A, C, and D all present contraindications for administering immunizations. Choice A is incorrect because giving BCG vaccines to a child with AIDS is a contraindication. Choice C is incorrect as convulsions after the first DPT dose indicate a contraindication to subsequent doses. Choice D is incorrect because active convulsions or other neurological diseases are contraindications to receiving the DPT vaccine.

4. For a patient on a ketogenic diet, which macronutrient is primarily increased?

• A. Carbohydrates
• B. Protein
• C. Fats
• D. Fiber

Correct answer: C

Rationale: The correct answer is C: Fats. A ketogenic diet is characterized by high fat intake, moderate protein intake, and very low carbohydrate intake. This diet aims to shift the body's metabolism to use fat as the primary source of energy instead of carbohydrates. Increasing fat intake while reducing carbohydrates is essential for achieving and maintaining a state of ketosis. Therefore, choices A, B, and D are incorrect as they do not align with the macronutrient adjustments required for a ketogenic diet.

5. The RR nurse should monitor for the most common postoperative complication of:

• A. hemorrhage
• B. endotracheal tube perforation
• C. osopharyngeal edema
• D. epiglottis

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
