The nurse provides a postoperative client with an analgesic medication and darkens the room before the client goes to sleep for the night. The nurse's actions:

Correct Answer: A

Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

Correct Answer: B

Rationale: The correct answer is B. Incident reports play a crucial role in risk management by providing data for analysis to prevent future problems. They are not primarily for liability protection (A) or disciplining staff (C). Therefore, choice B is the most appropriate answer. Choosing option D is incorrect because incident reports do not solely exist for all the mentioned purposes, but primarily to provide data for analysis and preventive actions.

Correct Answer: C

Rationale: The scenario describes classic impetigo, characterized by maculopapular lesions with honey-colored drainage, typically caused by Staphylococcus aureus or Streptococcus pyogenes. Antibiotic therapy is usually indicated for impetigo. Chickenpox, a highly contagious disease, presents with a history of high fever followed by a vesicular rash, different from the described maculopapular lesions with honey-colored drainage. Choice A is incorrect as the presentation is not consistent with chickenpox. Choice B is incorrect because impetigo is contagious, especially through direct contact. Choice D is also incorrect as impetigo is a contagious skin infection regardless of others having open wounds or lesions.

Correct Answer: D

Rationale: All of the provided choices are antiviral drug classes used in the treatment of HIV/AIDS. Nucleoside reverse transcriptase inhibitors, such as tenofovir and emtricitabine, work by interfering with the virus's ability to replicate. Protease inhibitors, like atazanavir and darunavir, block an enzyme that HIV needs to make copies of itself. HIV fusion inhibitors, for instance, enfuvirtide, prevent HIV from entering human cells. Therefore, 'all of the above' is the correct answer as all the listed drug classes are commonly used in managing HIV infections. Choices A, B, and C are all essential components of antiretroviral therapy for HIV, targeting different stages of the virus's life cycle. The combination of drugs from these classes is often recommended to effectively control HIV replication and reduce viral load.

Correct Answer: C

Rationale: Toradol is the correct answer because it is an NSAID known for its effectiveness in managing acute pain for short durations. It can be administered via intramuscular (IM), intravenous (IV), or oral (PO) routes. Advil (choice A) and Aleve (choice B) are commonly used for mild to moderate pain but may not be as effective for acute pain requiring immediate relief. Bextra (choice D) was withdrawn from the market due to safety concerns, making it an inappropriate choice for acute pain management.
