Nursing Elites

1. Which of the following are the primary bacteria involved in the initiation of dental caries?

• A. Streptococcus mutans and Lactobacillus species
• B. Salmonella and Listeria species
• C. Streptococcus, Lactobacillus, and Salmonella species
• D. Listeria, Botulinum species, and Escherichia coli

Correct answer: A

Rationale: The correct answer is A: Streptococcus mutans and Lactobacillus species. These bacteria are primarily responsible for initiating dental caries by fermenting carbohydrates and producing acids that demineralize enamel. Choice B, Salmonella and Listeria species, are not the primary bacteria involved in dental caries. Choice C includes Salmonella which is not a primary culprit in dental caries. Choice D lists Listeria, Botulinum species, and Escherichia coli, none of which are the primary bacteria associated with initiating dental caries.

2. Which vitamin is primarily obtained from sunlight exposure?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D is synthesized in the skin when it is exposed to sunlight. This process allows the body to produce Vitamin D naturally. Vitamin A (Choice A) is found in foods like liver and carrots and is not primarily obtained from sunlight. Vitamin C (Choice B) is commonly found in fruits and vegetables. Vitamin E (Choice D) is present in foods like nuts and seeds and is not primarily obtained from sunlight.

3. A nurse is caring for an older adult client who reports difficulty chewing due to ill-fitting dentures. Which of the following foods should the nurse recommend for the client?

• A. Dried fruit
• B. Roast beef
• C. Tuna fish
• D. Apple slices

Correct answer: C

Rationale: The correct answer is C: Tuna fish. Tuna fish is a soft and easy-to-chew option, suitable for clients with ill-fitting dentures. Dried fruit (choice A) can be tough to chew and may stick to the dentures, causing discomfort. Roast beef (choice B) requires significant chewing effort and may not be suitable for someone with difficulty chewing. Apple slices (choice D) are crunchy and hard, which can be challenging for individuals with ill-fitting dentures.

4. During operation, who manages the lighting, noise, temperature and other factors in the operating room suite?

• A. Nurse Supervisor
• B. Surgeon
• C. Circulating Nurse
• D. Scrub Nurse

Correct answer: C

Rationale: In an operating room, the circulating nurse is responsible for managing environmental factors such as lighting, noise, and temperature. This role includes ensuring the comfort and safety of the patient, as well as the efficiency of the team. While the Nurse Supervisor, Surgeon, and Scrub Nurse also have crucial roles during an operation, they do not directly manage the environmental conditions of the operating room. The rationale provided does not directly address the question asked, and appears to relate more to the broader role of nursing in patient care.

5. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:

• A. Cold compress reduces blood viscosity in the affected area
• B. It is safer to apply than a hot compress
• C. Cold compress prevents edema and reduces pain
• D. It eliminates toxic waste products due to vasodilation

Correct answer: C

Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.
