Without full lung expansion, which symptom is commonly experienced by the patient?

• A. Pain
• B. Great difficulty breathing
• C. Nausea
• D. Dizziness

Answer: (B)

When the lung hasn’t fully re-expanded, ventilation is compromised and the most common sign is trouble breathing. Incomplete expansion reduces the amount of air reaching the alveoli, which lowers oxygenation and increases the work of breathing. The body responds with rapid, shallow breaths and often use of accessory muscles, so the patient feels short of breath or breathless. Pain can occur, but it’s not as consistently linked to incomplete lung expansion as dyspnea. Nausea or dizziness may appear with hypoxia or other factors, but difficulty breathing remains the most typical and direct symptom.
