The nurse observes air bubbles in a patient's chest tube water seal chamber. How should the nurse interpret this finding?
1. normal
2. an emergency
3. an indication that the pneumothorax is worsening
4. an indication to remove the chest tube
Correct Answer: 1
Periodic air bubbles in the water-seal chamber are normal and indicate that trapped air is being removed from the chest. This is not an emergency situation, or one that indicates a worsening condition. The nurse would need a physician's order to remove a chest tube. The patient still needs the chest tube in place.
