The patient is undergoing in-patient physical therapy with increasing ambulation on the third day after a myocardial infarction. Which clinical manifestation would indicate to the nurse the patient should not be advanced to the next rehabilitation process?

A. Reinsert the tube into the chest tube insertion site: Reinserting a chest tube that has become dislodged is outside the scope of nursing practice and risks introducing infection and causing further trauma. Re-insertion must be performed by a qualified provider using sterile technique under appropriate conditions.

B. Insert the end of the chest tube in a container of sterile water: Placing the end of a dislodged chest tube into sterile water is appropriate only if the tube has disconnected from the drainage system but remains in the patient’s chest. In this scenario, the tube is lying on the floor, indicating it has been removed from the patient, so this action is not appropriate.

C. Auscultate the lung sounds in bilateral lung fields: Assessing lung sounds is important, but it is not the first priority. When a chest tube becomes dislodged from the patient, there is an immediate risk of air entering the pleural space and causing a tension pneumothorax. The insertion site must be addressed before further assessment.

D. Apply a sterile dressing to the chest tube insertion site: The priority is to immediately cover the insertion site with a sterile occlusive dressing (often taped on three sides) to prevent air from entering the pleural cavity and causing a life-threatening tension pneumothorax. This intervention directly addresses the most immediate physiological threat.

A. Call the provider: Notifying the provider may eventually be necessary, but immediate assessment is required first to determine the cause of constant bubbling. Calling the provider without assessing the system does not address the potential underlying problem.

B. Apply a sterile dressing to the chest tube insertion site: Applying a dressing is important for preventing infection but will not stop or explain constant bubbling in the water seal chamber. The priority is identifying whether the bubbling is due to an air leak.

C. Assess the chest tube connections: Constant bubbling in the water seal chamber usually indicates an air leak. The nurse should first inspect all tubing connections, insertion site, and the drainage system to locate and correct any leaks before notifying the provider or taking further action. Proper assessment ensures patient safety and prevents loss of negative pressure.

D. Place the patient on oxygen: Oxygen supplementation may be indicated for hypoxemia but does not address the cause of constant bubbling in the chest tube system. The immediate priority is identifying and correcting any mechanical or tubing-related issues.
