Correct Answer: B

Rationale: The correct answer is B: Assess for compartment syndrome. Severe unrelieved pain in a limb with traction can be a sign of compartment syndrome, a surgical emergency. Prompt assessment is crucial to prevent potential complications. Increasing pain medication dosage without addressing the underlying cause may delay necessary interventions. Waiting for the healthcare provider may lead to a critical delay in treatment. Repositioning the client may not alleviate the pain if it is due to compartment syndrome, and it is crucial to assess for this condition first.

Correct Answer: D

Rationale: In a postoperative patient, an oxygen saturation level of 88% on room air indicates a significant drop below the normal range, suggesting potential respiratory distress. This finding requires immediate intervention by the nurse to ensure the patient receives adequate oxygenation. A heart rate of 88 beats per minute is within the normal range, making it a less concerning finding. A blood pressure of 130/80 mmHg falls within the normal range for blood pressure and does not require immediate intervention. Crackles heard in the lung bases may indicate fluid accumulation but may not always require immediate intervention unless accompanied by other concerning signs or symptoms.

Correct Answer: B

Rationale: Correctly positioning a patient to reduce the risk of pressure ulcers involves using pillows to support bony prominences. This helps to relieve pressure from vulnerable areas and prevent the development of pressure ulcers. Choice A is incorrect because keeping a patient in the supine position for extended periods can increase the risk of pressure ulcers. Choice C is incorrect as turning the patient every 2 hours, rather than every 4 hours, is recommended to prevent pressure ulcers. Choice D is not the best option mentioned for positioning a patient to reduce pressure ulcer risk; although alternating pressure mattresses can be beneficial, using pillows for support is a more direct and commonly used method.

Correct Answer: B

Rationale: In a disaster situation like a building collapse, the nurse should attend to the victim with a partial amputation of a leg who is bleeding profusely first. This victim is at immediate risk of severe blood loss, which can be life-threatening. It is crucial to address life-threatening injuries like severe bleeding before attending to other less urgent cases. The victim with the amputation requires immediate intervention to control bleeding and stabilize their condition. Victims who are already deceased or have less urgent injuries can be attended to after addressing the critical cases.

Correct Answer: B

Rationale: The correct answer is to contact the stoma nurse to assist the client with care. Stoma nurses are specially trained to provide guidance on stoma care, especially for clients with new ostomies. Instructing the client to care for the stoma independently (Choice A) may not be appropriate initially as they may need professional guidance. Delegating the care of the stoma to a nursing assistant (Choice C) is not recommended as specialized care is required. Waiting until the next shift (Choice D) is not ideal as stoma care should not be delayed.
