Final answer:
Based on the symptoms, the patient may have suffered a pneumothorax or collapsed lung and further examination is needed to confirm the diagnosis.
Step-by-step explanation:
Based on the symptoms, it is likely that the patient has suffered a pneumothorax or collapsed lung, which can result from an injury to the chest. The difficulty breathing and chest pain indicate a potential lung injury. Cyanosis, the bluish discoloration of the skin and mucous membranes, suggests a lack of oxygen. To further assess the extent of the injury and provide appropriate treatment, the next step would be to perform a focused physical examination of the chest and potentially order imaging tests such as a chest X-ray to confirm the diagnosis.
