1. Which of the following microorganisms are considered normal body flora?

A. staphylococcus on the skin
B. streptococcus in the nares
C. candida albicans in the vagina
D. pseudomonas in the blood

Correct answer: A

Rationale: Staphylococcus is considered normal body flora as it is commonly found on the skin, being a part of the normal microbiota. While streptococcus in the nares can be part of the normal flora of the upper respiratory tract, it is not as common or as widespread as staphylococcus on the skin. Candida albicans in the vagina is not considered normal flora; it is a common opportunistic pathogen in the vagina. Pseudomonas in the blood is also not considered normal body flora; pseudomonas is not typically found in the blood as part of the normal microbiota.

2. The healthcare provider sustains a needle puncture that requires HIV prophylaxis. Which of the following medication regimens should be used?

A. an antibiotic such as Metronidazole and a protease inhibitor (Saquinavir)
B. two non-nucleoside reverse transcriptase inhibitors
C. one protease inhibitor such as Nelfinavir
D. two protease inhibitors

Correct answer: B

Rationale: In the scenario of a needle puncture requiring HIV prophylaxis, the CDC recommends initiating treatment with two non-nucleoside reverse transcriptase inhibitors, unless there is drug resistance. This regimen is preferred over other options such as a single protease inhibitor or two protease inhibitors due to its effectiveness and safety profile in this specific context. Non-nucleoside reverse transcriptase inhibitors are commonly used in post-exposure prophylaxis due to their activity against HIV and lower risk of resistance development compared to other antiretroviral drug classes.

3. How many temporary teeth should the nurse expect to find in a 5-year-old client's mouth?

A. up to 10
B. up to 15
C. up to 20
D. up to 32

Correct answer: C

Rationale: A 5-year-old child can have up to 20 temporary (deciduous or baby) teeth. The first tooth usually erupts by age 6 months, and the last by age 30 months. All temporary teeth are usually shed between 6 and 13 years of age. Therefore, a 5-year-old child should have up to 20 temporary teeth. The correct answer is 'up to 20.' Choices A, B, and D are incorrect because the correct number of temporary teeth in a 5-year-old child's mouth is up to 20, not 10, 15, or 32.

4. A licensed practical nurse (LPN) works on an adult medical/surgical unit and has been pulled to work on the burn unit, which cares for clients of all ages. What should the LPN do?

A. The LPN should take the assignment, but make it clear they will only care for adult clients.
B. The LPN should take the assignment, but explain the situation to the charge nurse and ask for a quick orientation before starting.
C. The LPN should refuse to take the assignment, as caring for the infant and child population is not within their scope of practice.
D. The LPN should take the assignment, but ask to be paired with a more experienced LPN.

Correct answer: B

Rationale: In this scenario, it is crucial for the LPN to demonstrate flexibility and a willingness to adapt to the new assignment that involves caring for clients of all ages. While the LPN may have expertise in a specific nursing area, it is essential to be able to provide care to diverse client populations. Accepting the assignment reflects a commitment to teamwork and patient care. However, to ensure safe and competent care, the LPN should communicate with the charge nurse about the situation. Requesting a quick orientation will help the LPN familiarize themselves with the burn unit's specific requirements, equipment, and protocols. This proactive approach allows the LPN to address any concerns, ask questions, and seek necessary support, ultimately ensuring the best care for all clients in the burn unit. Choice A is incorrect because limiting care to only adult clients may not be feasible in a unit that cares for clients of all ages. Choice C is incorrect as refusing the assignment outright may not be the best approach without considering alternatives. Choice D is not the most effective option as asking to be paired with a more experienced LPN does not address the need for a quick orientation to the new unit.

5. How does cancer affect pain tolerance in elderly clients?

A. Remain constant.
B. Decrease.
C. Increase.
D. Cancer has no impact on pain tolerance in elderly clients.

Correct answer: B

Rationale: Pain tolerance in elderly clients with cancer is likely to decrease due to factors such as diminished adaptative capacity, increased physical discomfort, and the psychological impact of the disease. Cancer is known to cause various physical and emotional stressors that can lower the pain threshold, leading to a decrease in pain tolerance. Choices A, C, and D are incorrect because cancer and its associated effects typically result in a decrease in pain tolerance rather than remaining constant, increasing, or having no impact.
