Correct Answer: B

Rationale: Verifying the patient's identity using two identifiers is crucial to ensure the right patient receives the right medication. This process helps prevent medication errors by confirming the patient's identity through at least two unique identifiers, such as name, date of birth, or medical record number. Choice A is not directly related to ensuring patient safety during medication administration. Choice C is incorrect as medications should be prepared in a sterile environment, not just at the healthcare professional's station. Choice D is not a safe practice as medications should be administered at the scheduled time to maintain therapeutic effectiveness.

Correct Answer: B

Rationale: The correct first course of action for a nurse suspecting a colleague of diverting narcotics is to report the suspicion to the nurse manager. Confronting the colleague directly may not be safe and could compromise the investigation. Ignoring the situation is not appropriate as it can pose risks to patient safety. Keeping a record of the colleague's actions is not the primary action to take when drug diversion is suspected; reporting to the nurse manager is crucial for proper investigation and ensuring patient safety.

Correct Answer: A

Rationale: The correct answer is A. The sink is considered a contaminated area. When hand hygiene is compromised during the process, it is essential to repeat handwashing using antiseptic soap to ensure proper hygiene. Choice B is incorrect because the situation can be managed by proper handwashing. Choice C is incorrect as extending the handwashing procedure to 5 minutes is not necessary in this scenario. Choice D is incorrect as the hands need to be properly cleaned before assisting the healthcare provider.

Correct Answer: A

Rationale: The correct answer is A. Providing oral care every 4 hours helps prevent ventilator-associated pneumonia by reducing the buildup of bacteria in the mouth that can be aspirated into the lungs. Repositioning the patient every 2 hours is important for preventing pressure ulcers but is not directly related to preventing VAP. Suctioning the patient as needed is essential for maintaining airway patency but does not specifically prevent VAP. Administering antibiotics as prescribed is a treatment for infections but does not prevent VAP.

Correct Answer: A

Rationale: The correct answer is to turn and reposition the patient every 2 hours. This intervention is crucial in preventing pressure ulcers and maintaining skin integrity by relieving pressure on bony prominences. Applying a moisture barrier (Choice B) is important for moisture-associated skin damage but is not the priority in this case. Massaging the patient's skin (Choice C) can potentially cause friction and shear, increasing the risk of skin breakdown. Applying a heating pad (Choice D) can lead to burns or thermal injuries, exacerbating skin integrity issues.
