ATI Detailed Answer Key Medical Surgical

Correct Answer: A

Rationale: Arterial blood gases are crucial to assess postoperatively in a client who has undergone thoracotomy and lobectomy to monitor oxygenation and ventilation status. Changes in arterial blood gases can indicate respiratory complications or inadequate gas exchange, which are critical issues that need prompt intervention to prevent further complications. While urinary output, chest tube drainage, and pain level are important assessments, monitoring arterial blood gases takes precedence in this specific postoperative scenario to ensure optimal respiratory function and overall patient well-being.

Correct Answer: A

Rationale: An increased respiratory rate from 18 to 44/min is a significant change that should alert the healthcare professional to a potential serious complication. Such a drastic increase in respiratory rate may indicate respiratory distress or hypoxia, which are critical conditions requiring immediate attention. The other options show minor changes in vital signs that are within normal limits and are less likely to indicate a serious complication.

Correct Answer: A

Rationale: In a closed chest drainage system, slow, steady bubbling in the suction control chamber is an expected finding, indicating proper functioning of the system. There is no immediate need for intervention as this indicates the system is working as intended. The nurse should continue to monitor the client's respiratory status for any signs of distress or changes. Checking tubing connections for leaks or clamping the chest tube are unnecessary actions based on the information provided. Checking the suction control outlet on the wall is also not indicated in this scenario.

Correct Answer: A

Rationale: Preventing aspiration is the priority for a client with intermaxillary fixation following mandibular surgery. Aspiration can occur due to difficulty swallowing or improper positioning, posing a serious risk to the client's respiratory status. It is crucial for the nurse to ensure that the client's airway is clear and that they are positioned correctly to prevent any potential aspiration events.

Correct Answer: B

Rationale: Emphysema is a chronic lung condition characterized by shortness of breath (dyspnea), a barrel-shaped chest due to hyperinflation of the lungs (barrel chest), and clubbing of the fingers (enlargement of fingertips). Bradycardia (slow heart rate) is not typically associated with emphysema. In emphysema, the primary focus is on respiratory complications rather than cardiac issues.
