Correct Answer: B

Rationale: The most important nursing intervention when caring for a patient with a wound is to clean the wound with normal saline. This is crucial for preventing infection and promoting healing. Applying an occlusive dressing (Choice A) can be important but should come after cleaning the wound. Administering antibiotics (Choice C) is not the first-line intervention for all wounds and should be based on the healthcare provider's prescription. Reassessing the wound (Choice D) is essential but not the most important initial intervention.

Correct Answer: A

Rationale: Auscultating the entire lung region is the most appropriate action when assessing a patient for respiratory complications related to immobility. This approach helps the nurse identify any abnormalities in lung sounds, such as diminished breath sounds or the presence of secretions. Assessing the patient at regular intervals (choice B) is important but does not specifically address the respiratory assessment needed in this situation. Focusing auscultation on the upper lung fields (choice C) may miss potential issues in other areas. Inspecting chest wall movements primarily during the expiratory cycle (choice D) is not the most effective way to assess lung sounds and identify respiratory complications.

Correct Answer: B

Rationale: When a nurse observes a colleague behaving strangely, the best course of action is to report the behavior to the supervisor. Unusual behavior by a healthcare professional could compromise patient safety and should be addressed promptly. Ignoring the behavior (Choice A) could potentially lead to negative outcomes for patients. Asking the colleague directly (Choice C) may not be appropriate if the behavior poses a risk. Discussing the behavior with other colleagues (Choice D) may not directly address the issue and could lead to gossip rather than a resolution.

Correct Answer: B

Rationale: If a nurse manager assigns a nursing assistant a task that is outside of their role, the nursing assistant should report the task to the charge nurse. This is important because the charge nurse can provide guidance on whether the task is appropriate for the nursing assistant to perform. Choice A is incorrect because blindly following a directive that is outside of the nursing assistant's scope could lead to negative consequences. Choice C might not be the best course of action initially, as it's important to seek clarification first. Choice D is also not the best option because performing a task outside of one's role without proper authorization can pose risks to both the patient and the nursing assistant.

Correct Answer: B

Rationale: During a fire emergency, it is crucial to close all doors to contain smoke and fire, helping to protect the patients. This action can prevent the spread of fire and smoke to the area where patients are located. Identifying evacuation routes is also important for a timely and orderly evacuation if necessary. Waiting for the fire department to arrive before taking action (Choice A) can waste valuable time and put patients at risk. Moving bedridden patients in their beds (Choice D) can be dangerous during a fire and should be avoided as it can expose patients and staff to more risks.
