NREMT Paramedic Cognitive ExamOperationsHard
A paramedic is transporting a critically ill patient who requires continuous positive pressure ventilation via an endotracheal tube. The patient's condition suddenly deteriorates, and during assessment, the paramedic notes absent breath sounds on the left side, tracheal deviation to the right, and increasing difficulty with ventilations. What is the most appropriate immediate action?
- AIncrease the ventilatory rate and tidal volume.
- BDeflate the endotracheal tube cuff and reposition the tube.
- CPerform needle decompression on the left side of the chest.
- DAdminister a bronchodilator via nebulizer.
Show answer & explanationAnswer & explanation
Correct answer: C. Perform needle decompression on the left side of the chest.
The signs and symptoms (absent breath sounds on the left, tracheal deviation to the right, increasing difficulty with ventilations) are classic for a tension pneumothorax. This is a life-threatening condition that requires immediate needle decompression to relieve the pressure and restore lung function.
Why the other options are wrong
- A. Increasing ventilatory support will worsen a tension pneumothorax by forcing more air into the pleural space.
- B. While tube displacement is a consideration, tracheal deviation and absent breath sounds on one side with difficulty ventilating point strongly to tension pneumothorax, not just tube issues.
- D. A bronchodilator is for bronchospasm, not for a mechanical issue like a tension pneumothorax.
Tension Pneumothorax
A life-threatening condition where air enters the pleural space but cannot escape, building up pressure that collapses the lung and shifts mediastinal structures, impairing cardiac output.
- Absent breath sounds on affected side.
- Tracheal deviation (late sign, away from affected side).
- Increasing respiratory distress, hypotension, difficulty ventilating.
- Requires immediate needle decompression.
Memory trick: Tracheal shift, no breath, needle's gift, or face death.
