Rationale: The correct answer is B: 'Ensure the cane has a rubber tip.' This instruction is essential for safety as the rubber tip prevents slipping, providing stability. Choice A is incorrect because the cane should be held on the stronger side to provide better support and balance. Choice C is incorrect as the cane should be used on the stronger, more dominant side. Choice D is also incorrect as a cane is not only used on stairs but also for general support and mobility.

Rationale: The correct answer is to apply a moisture-retentive dressing. This type of dressing promotes a moist wound environment, which is crucial for wound healing. Applying a heating pad can lead to tissue damage, while daily wound irrigation can disrupt the wound healing process. Applying an ice pack is not recommended for promoting wound healing in this scenario.

Decreased respiratory rate (choice D) is not a typical finding in COPD and could indicate respiratory depression.

Correct Answer: C

Rationale: The correct action for the nurse to take when administering medications through an NG tube is to dissolve each medication separately and flush with water between medications. This practice helps prevent interactions between medications and ensures that each medication is delivered effectively. Option A is incorrect as mixing all medications together can lead to chemical interactions or alter the effectiveness of the medications. Option B is incorrect because flushing the NG tube with air is not recommended and may cause harm. Option D is incorrect as administering all medications at the same time does not allow for proper absorption and interaction control.

Correct Answer: B

Rationale: When admitting a client with meningococcal meningitis, the nurse's priority should be to place the client on droplet precautions. This is crucial to prevent the spread of the infection to others. Administering antibiotics, performing a lumbar puncture, and initiating seizure precautions are important interventions but should come after implementing droplet precautions to ensure the safety of both the client and others.
