ATI Detailed Answer Key Medical Surgical

Correct Answer: B

Rationale: Continuous bubbling in the water-seal chamber indicates an air leak, which can compromise the system's integrity and affect the client's respiratory status. The other options are expected findings in a client with a chest tube drainage system: constant bubbling in the suction-control chamber indicates proper suction function, bloody drainage in the collection chamber is expected in the immediate postoperative period, and fluid-level fluctuations in the water-seal chamber demonstrate normal drainage and lung re-expansion.

Correct Answer: C

Rationale: Chronic bronchitis is often linked to smoking. Smoking cessation is the most effective preventive measure to reduce the risk of developing chronic bronchitis. Smoking damages the airways and leads to inflammation, making individuals more susceptible to chronic bronchitis. While maintaining an ideal weight, getting an annual influenza vaccine, and engaging in regular moderate exercise are beneficial for overall health, the most crucial intervention to prevent chronic bronchitis is quitting smoking.

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: B

Rationale: When caring for a client with burns, especially burns to the face and chest, the priority action for the nurse is to inspect the mouth for signs of inhalation injuries. Inhalation injuries can be life-threatening and may not be immediately apparent. Identifying these injuries early allows for prompt intervention and can significantly impact the client's outcomes. While other actions such as pain management and blood tests are important, assessing for inhalation injuries takes precedence due to its critical nature.

Correct Answer: A

Rationale: Fluctuation of the fluid level within the water seal chamber indicates proper functioning of the chest tube. This fluctuation reflects the normal ebb and flow of air and fluid in the pleural space, demonstrating that the system is maintaining the appropriate pressure. Continuous bubbling in the water seal chamber may indicate an air leak, absence of fluid in the drainage tubing suggests a blockage, and equal amounts of fluid drainage in each collection chamber are not expected in this system.
