Correct Answer: B

Rationale: Applying the AED pads is the immediate next step after obtaining the AED in a cardiac arrest situation. Placing the pads correctly on the client's chest is crucial for the AED to analyze the heart rhythm accurately and deliver a shock if needed. Following the prompts of the AED comes after the pads are in place. Wiping the client's chest dry or moving the client from the bathroom are not priorities at this critical moment and may delay life-saving interventions.

Correct Answer: B

Rationale: When implementing a disaster intervention plan, the first step the nurse should take is to identify a command center where activities are coordinated. This step is crucial for ensuring an organized and effective disaster response. Option A, initiating the discharge of stable clients, is not a priority during the initial phase of disaster response. Option C, assessing community safety needs, usually follows setting up a command center. Option D, instructing off-duty personnel to report, may be necessary but is not the primary intervention at the beginning of a disaster situation.

Correct Answer: B

Rationale: The correct action for the nurse to implement immediately upon identifying clear fluid on the surgical dressing post-lumbar surgery is to test the fluid for glucose. Clear fluid could indicate cerebrospinal fluid (CSF) leakage, and testing for glucose can help confirm this. Changing the dressing using a compression bandage (Choice A) without further assessment could lead to complications. Documenting the findings (Choice C) is important but not as immediate as confirming the presence of CSF. Marking the drainage area with a pen and monitoring (Choice D) does not address the need for immediate confirmation of CSF leakage.

Correct Answer: B

Rationale: The most important action to take in this situation is to record 'no known drug allergies' on the preoperative checklist. This ensures that all healthcare staff involved in the surgery are aware of the client's stated lack of drug allergies, helping to prevent any potential adverse reactions. Assessing the client's knowledge of an allergic response (Choice A) may be valuable but is not the most crucial action at this point. Flagging 'no known drug allergies' on the front of the chart (Choice C) is less practical and visible compared to documenting it on the preoperative checklist. Assessing the client's allergies to non-drug substances (Choice D) is not the priority in this scenario where the focus is on medications due to the upcoming surgery.
