Correct Answer: C

Rationale: The appropriate nursing response in this situation is to ask the client if there are any concerns about the procedure. By doing so, the nurse acknowledges the client's distress and opens up a dialogue to address any anxieties or misconceptions. Option A is incorrect as ignoring the client's discomfort can lead to increased anxiety and potential harm. Option B is not ideal as reassuring the client without addressing specific concerns may not alleviate the client's distress. Option D is incorrect because proceeding with the procedure without addressing the client's unspoken concerns can further escalate the client's distress.

Correct Answer: A

Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.

Correct Answer: D

Rationale: The correct answer is D: Joint contractures. When a healthcare provider performs passive ROM and splinting on a patient, the goal is to prevent joint contractures. Joint contractures result from immobility and can lead to permanent stiffness and decreased range of motion. Atelectasis (choice A) is a condition where there is a complete or partial collapse of the lung, commonly due to immobility, but not directly related to passive ROM or splinting. Renal calculi (choice B) are kidney stones and are not typically associated with ROM exercises. Pressure ulcers (choice C) result from prolonged pressure on the skin and are prevented by repositioning the patient, not specifically addressed by ROM and splinting exercises.

Correct Answer: A

Rationale: If an NG tube is obstructed and cannot be irrigated successfully, notifying the healthcare provider is the appropriate action to take for further management. This is crucial as the healthcare provider may need to assess the situation, provide guidance, or intervene with specific interventions. Attempting to irrigate the tube with a larger volume of saline (Choice B) may exacerbate the situation if the tube is truly obstructed. Replacing the NG tube with a new one (Choice C) should not be the initial action unless advised by the healthcare provider. Repositioning the client (Choice D) may not necessarily resolve the tube obstruction and should not be the primary intervention in this scenario.

Correct Answer: B

Rationale: In a mass casualty scenario, the triage nurse would prioritize the toddler with severe deep abrasions covering over 98% of the body for treatment last. This child is categorized as 'expectant' due to the extensive injuries, which are unlikely to be survivable even with immediate treatment. The other choices describe injuries that are serious but have a higher likelihood of survival with appropriate and timely intervention. The infant with an intermittent bulging anterior fontanel may have increased intracranial pressure requiring urgent evaluation, the preschooler with leg fractures can be stabilized and treated effectively, and the school-age child with singed hair likely has superficial burns which can be managed promptly.
