Nursing Elites

1. Which of the following groups of vitamins are fat-soluble?

• A. vitamins B and C
• B. vitamins A and C
• C. vitamins B, E, K, D
• D. vitamins A, E, K, D

Correct answer: D

Rationale: The correct answer is D: vitamins A, E, K, and D. Fat-soluble vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamins B and C are water-soluble vitamins and are not stored in the body; any excess amounts are usually excreted in the urine. Therefore, choices A, B, and C are incorrect.

2. 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.

3. A patient who is recovering from surgery should increase their intake of which nutrient to promote healing?

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

Correct answer: C

Rationale: Protein is crucial for tissue repair and recovery after surgery. Proteins provide the building blocks necessary for tissue healing and regeneration. Fats are important for various bodily functions but are not as directly involved in tissue repair as proteins. Carbohydrates provide energy but do not play a primary role in tissue healing. Fiber is essential for digestive health but is not a nutrient that directly promotes tissue repair.

4. A nurse is preparing a teaching plan for a client who has neutropenia as a result of radiation therapy for the treatment of lung cancer. Which of the following should the nurse plan to include in the teaching?

• A. Bottled water is an appropriate choice to increase fluid intake.
• B. The salad bar is a healthy choice when dining out.
• C. Soft-boiled eggs are an appropriate source of protein.
• D. Eating at a buffet is a good choice to increase caloric intake.

Correct answer: A

Rationale: In neutropenia, which is a low count of neutrophils, the client is at a high risk of infection. It is crucial to emphasize the importance of proper hydration to maintain overall health. Bottled water is a safe choice as it reduces the risk of exposure to contaminants that could further compromise the client's immune system. The other options, like the salad bar, soft-boiled eggs, and eating at a buffet, may not be suitable for a client with neutropenia due to the risk of bacterial contamination or exposure to pathogens that could lead to infections, which should be avoided.

5. Which is most likely to initiate periodontal disease?

• A. Nutrient deficiencies
• B. Nutrient excesses
• C. Nutrient imbalances
• D. Plaque biofilm

Correct answer: D

Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.
