1. What is the most significant dietary influence on the development of dental caries?

• A. Carbohydrates
• B. Vitamins
• C. Minerals
• D. Fats

Correct answer: A

Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.

2. A client is being prepared for placement of a catheter for total parenteral nutrition. Which of the following access sites should be planned for catheter insertion?

• A. Left antecubital vein
• B. Right subclavian vein
• C. Right femoral artery
• D. Left arm radial artery

Correct answer: B

Rationale: The correct answer is the Right subclavian vein. When preparing a client for placement of a catheter for total parenteral nutrition, the preferred access site for catheter insertion is the subclavian vein due to its large size, central location, and lower risk of infection compared to peripheral veins. The other options provided (Left antecubital vein, Right femoral artery, and Left arm radial artery) are not suitable access sites for central venous catheter insertion for total parenteral nutrition.

3. A nurse is providing dietary teaching to a client who has a new diagnosis of gastroesophageal reflux disease. Which of the following foods or beverages should the nurse recommend to minimize heartburn?

• A. Orange juice
• B. Decaffeinated coffee
• C. Peppermint
• D. Potatoes

Correct answer: D

Rationale: Potatoes are bland and less likely to relax the lower esophageal sphincter, making them a suitable choice to minimize heartburn in clients with gastroesophageal reflux disease. Orange juice and peppermint are acidic and can exacerbate GERD symptoms, while coffee, even decaffeinated, can stimulate acid production and worsen heartburn.

4. You are on duty in the medical ward. You were asked to check the narcotics cabinet. You found out that what is on record does not tally with the drugs used. What will you do first?

• A. Write an incident report and refer the matter to the nursing director
• B. Keep your findings to yourself
• C. Report the matter to your supervisor
• D. Find out from the endorsement any patient who might have been given narcotics

Correct answer: C

Rationale: In this situation, the first step should be to report the matter to your supervisor. It is essential to notify the appropriate authority immediately to address the discrepancy in the narcotics cabinet. Choice A is not the first step as reporting to the nursing director should follow after informing the supervisor. Keeping the findings to yourself (Choice B) is not appropriate as it may jeopardize patient safety and is against ethical standards. While finding out which patient received narcotics (Choice D) is important, it is not the immediate action to take in this scenario.

5. What is the digestive action of lipase?

• A. It breaks down carbohydrates
• B. It breaks down proteins
• C. It breaks down lipids
• D. It aids in fat digestion

Correct answer: C

Rationale: Lipase is an enzyme that specifically breaks down lipids (fats) during the process of digestion, converting them into fatty acids and glycerol. This is why option C is the correct answer. Although option D is partially correct, it's less specific than option C. Lipase does not break down carbohydrates or proteins, so options A and B are incorrect.
