NREMT Emergency Medical Technician (EMT) Cognitive ExamAirway, Respiration & VentilationHard
A 68-year-old male complains of sudden onset of severe shortness of breath and sharp chest pain that worsens with inhalation. On examination, you find diminished breath sounds on the right side, tracheal deviation to the left, and jugular venous distension. His skin is cool, pale, and diaphoretic. What is the most likely underlying condition?
- ACongestive heart failure.
- BTension pneumothorax.
- CPulmonary embolism.
- DAcute myocardial infarction.
Show answer & explanationAnswer & explanation
Correct answer: B. Tension pneumothorax.
The combination of sudden shortness of breath, pleuritic chest pain, diminished breath sounds on one side, tracheal deviation, and jugular venous distension is the classic presentation of a tension pneumothorax. This is a life-threatening condition where air accumulates in the pleural space under pressure, collapsing the lung and shifting mediastinal structures.
Why the other options are wrong
- A. Congestive heart failure typically presents with progressive shortness of breath, crackles (rales) in both lungs, and JVD, but not unilateral diminished breath sounds or tracheal deviation.
- C. Pulmonary embolism can cause sudden shortness of breath and pleuritic chest pain, but rarely causes tracheal deviation or jugular venous distension unless it leads to severe right heart failure and shock.
- D. Myocardial infarction typically presents with crushing chest pain, often radiating, and possibly shortness of breath, but usually without tracheal deviation or unilateral diminished breath sounds.
Tension Pneumothorax
A life-threatening condition where air accumulates in the pleural space under positive pressure, causing lung collapse, mediastinal shift, impaired venous return, and cardiovascular compromise.
- Key signs: sudden dyspnea, pleuritic chest pain, diminished/absent breath sounds on affected side, tracheal deviation (late sign), JVD, hypotension, tachycardia.
- Requires immediate decompression (needle thoracostomy) to relieve pressure.
- Often results from trauma but can occur spontaneously.
Memory trick: Unilateral breath sounds with a shifted trachea means tension's got ya!
