CHAPTER 2 Respiratory System^119
- Mediastinal shift and tracheal deviation toward the unaffected side with ten-
sion pneumothorax 
INTERPRETING TEST RESULTS
- Shadows on chest x-ray, indicating a collapsed lung.
 - Increased carbon dioxide shown in arterial blood gas.
 - Low oxygen saturation on pulse oximetry.
 
TREATMENT
Once identified, a pneumothorax can be treated and completely resolved. A ten-
sion pneumothorax can become a life-threatening condition. Careful monitoring
and early intervention is critical for these patients. A small area may resolve with-
out intervention, but the patient will still be monitored until resolution.
- Bedrest.
 - Supplemental oxygen if needed.
 - Chest tube connected to suction to re-expand lung if needed.
 - Administer analgesic if needed:
- morphine
 
 
NURSING DIAGNOSES
- Acute pain
 - Ineffective breathing
 - Impaired gas exchange
 
NURSING INTERVENTION
- Place patient in high Fowler’s or semi-Fowler’s position to ease respiratory
effort. - Monitor drainage of the chest tube for amount and characteristics of output.
Note changes. - Monitor vital signs for changes.
