This PDF is an educational practice quiz created by NursingSOS for nursing students and professionals. It contains ten multiple‑choice or select‑all‑that‑apply questions covering the core concepts of pneumothorax and tension pneumothorax, followed by an answer key with rationales. The content reviews the fundamental distinction between simple and tension pneumothorax, typical symptoms and signs (chest pain, tachycardia, unequal chest expansion, tracheal deviation, hypotension, hyperresonance), assessment techniques (percussion, palpation for subcutaneous emphysema), immediate interventions (three‑sided occlusive dressing for open pneumothorax, supplemental oxygen), optimal patient positioning, and the underlying pathophysiology of air entering the pleural space. The quiz aims to reinforce nursing assessment, prioritization, and emergency management skills while providing clear explanations for each answer.
Questions this document answers
C) The ability of air to escape the pleural space (or not). The rationale: In a pneumothorax, air enters and leaves the pleural space; in a tension pneumothorax, air enters but cannot escape, leading to increased pressure.
2, 3, 5 – Chest pain, increased heart rate (tachycardia), unequal chest wall expansion. Rationale: These are typical; tracheal deviation and hypotension suggest tension pneumothorax.
A) Improve tissue oxygenation. Rationale: Oxygen increases the amount of O₂ in the blood, compensating for reduced lung function.
C) Hyperresonance. Rationale: Air in the pleural space produces a louder, lower‑pitched sound.
D) Application of a three‑sided occlusive dressing. Rationale: Creates a flutter‑valve allowing air out but not in, preventing tension.
