This question tests chest tube monitoring and troubleshooting skills, specifically infection prevention at the chest tube insertion site. The key assessment findings are signs of infection including erythema, warmth, purulent drainage, and fever (38.6°C), requiring proper wound care interventions. Changing the dressing using sterile technique and performing hand hygiene before and after care (A) is the correct intervention because it follows infection control principles and prevents further contamination. Milking the chest tube (B) is contraindicated as it can cause tissue damage and increased negative pressure, applying petroleum gauze with an open dressing (C) would not properly protect the site from contamination, and delegating insertion site assessment to UAP (D) is inappropriate as this requires nursing assessment skills. The fundamental principle is that chest tube insertion sites require meticulous sterile technique and regular assessment to prevent and manage infections, which can lead to empyema or sepsis. When caring for chest tube sites with signs of infection, always use strict sterile technique, obtain cultures as ordered, and monitor for systemic infection while maintaining the integrity of the drainage system.

This question tests chest tube monitoring and troubleshooting skills. Key assessment findings include rapid drainage of dark red blood with signs of shock like hypotension and tachycardia. The finding of 250 mL drainage in 30 minutes with hypotension and tachycardia best indicates a complication, as it suggests hemorrhage. No bubbling at rest (B) can be normal if the hemothorax is resolving, tidaling (C) is expected, and 30 mL serosanguineous drainage (D) is typical. Excessive output signals ongoing bleeding that may require surgical intervention. The rationale is monitoring for drainage exceeding 200 mL/hour to prevent hypovolemia. A transferable strategy is to correlate drainage trends with vital signs for early detection of bleeding.

This question tests chest tube monitoring and troubleshooting skills. Key assessment findings include sustained high drainage with instability indicating need for escalation. Notifying the provider of excessive output and continuing monitoring is the best action, as it prompts intervention. Lowering suction (B) may not control bleeding, flushing (C) is contraindicated, and documenting without action (D) is inadequate. Persistent high output signals complication. The rationale is early reporting prevents shock. A transferable strategy is to trend drainage and vital signs hourly.

This question tests chest tube monitoring and troubleshooting skills. Key assessment findings include abrupt cessation of drainage with kinked tubing and signs of distress indicating obstruction. Straightening the tubing to remove the kink and reassessing is the best action, as it restores patency. Clamping (B) worsens obstruction, measuring length (C) is irrelevant, and pain medication (D) delays correction. Kinks prevent drainage, causing pressure buildup. The rationale is ensuring unobstructed flow. A transferable strategy is to secure tubing to avoid kinks during positioning.

This question tests chest tube monitoring and troubleshooting skills. Key assessment findings include excessive bright red drainage with signs of hemodynamic instability like tachycardia and hypotension, indicating potential hemorrhage. The finding of 350 mL bright red blood in 1 hour with worsening tachycardia is the best indicator of a complication, as it suggests active bleeding requiring immediate intervention. Tidaling (A) is normal, small intermittent bubbling with coughing (C) is expected in hemothorax, and 200 mL serosanguineous drainage over 8 hours (D) is within normal limits post-trauma. Excessive drainage can lead to hypovolemic shock if not addressed promptly. The rationale is that chest tube output greater than 200-300 mL/hour signals a complication like vascular injury. A transferable strategy is to monitor drainage volume, color, and vital signs hourly in the initial postoperative period to detect complications early.

This question tests chest tube monitoring and troubleshooting skills. Key assessment findings include continuous bubbling in the water-seal chamber post-thoracic surgery, suggesting a possible system air leak. Assessing tubing connections and insertion-site dressing for loose seals is the best action, as it identifies and corrects external leaks. Notifying the provider without assessment (A) delays troubleshooting, adding water to the suction chamber (C) addresses the wrong chamber, and increasing oxygen (D) treats symptoms but not the cause. Continuous bubbling can indicate a breach in the closed system, leading to ineffective drainage. The principle is to ensure system integrity for proper pleural evacuation. A transferable strategy is to inspect all connections and dressings first when bubbling is abnormal.

This question tests chest tube monitoring and troubleshooting skills. Key interventions include immediate coverage of the dislodged chest tube site to prevent air entry while allowing escape to avoid tension pneumothorax. Applying a sterile occlusive dressing taped on three sides is the best action, as it creates a one-way valve for air exit. High-Fowler position (B) does not address the open wound, clamping (C) is unnecessary since the tube is dislodged, and obtaining a chest x-ray (D) delays urgent intervention. This prevents atmospheric air from entering the pleural space, which could collapse the lung. The principle is based on maintaining negative intrapleural pressure. A transferable strategy is to always have emergency supplies like occlusive dressings ready for chest tube dislodgement.

This question tests chest tube monitoring and troubleshooting skills. Key assessment findings include continuous bubbling suggesting a possible external air leak. Checking for loose connections and ensuring the dressing is occlusive is the best action, as it locates and fixes system breaches. Documenting as expected (B) ignores potential issues, emptying the chamber (C) is incorrect, and antibiotics (D) are unrelated. Continuous bubbling post-op may indicate unresolved leaks. The principle is maintaining a sealed system. A transferable strategy is to systematically trace the tubing for defects when bubbling is continuous.

This question tests chest tube monitoring and troubleshooting skills. Key interventions include covering the open site to prevent air entry while allowing exit during exhalation. Covering with sterile petrolatum gauze taped on three sides is the best action, as it acts as a flutter valve. Firm pressure on all sides (B) traps air, reinserting (C) is unsafe, and supine position (D) does not address the wound. This prevents tension pneumothorax. The principle is one-way air flow. A transferable strategy is to use vented dressings for dislodgement emergencies.

This question tests chest tube monitoring and troubleshooting skills. Key assessment findings include dependent loops causing obstruction, leading to backed-up fluid and dyspnea. A dependent loop with obstruction and worsening oxygenation best indicates a complication, as it prevents proper drainage. No bubbling at rest (B) is normal, upright system (C) is correct, and changing drainage color (D) is expected. Obstructions can cause tension hemothorax. The rationale is that gravity-dependent positioning ensures flow. A transferable strategy is to coil excess tubing without loops to maintain patency.
