The correct answer to this question is option B – Diminished breath sounds Pneumothorax is the term used to describe the presence of air inside the pleural cavity (space between the lungs and the chest wall), usually caused by injury either to the lungs or to the chest wall. Air escape from the lungs to the pleural space causing the insufficient supply of air, the abnormal accumulation of air in the pleural space pushes the lungs causing the affected lung to collapse.
The symptoms of pneumothorax include shortness of breath, diminished breath sounds, sudden sharp chest pain. Option A is incorrect because, in most cases, pneumothorax leads to a higher respiratory rate rather than a low respiratory rate. Barrel chest is a condition where the rib cage broadens. This is commonly seen in obstructive pulmonary disease such as emphysema. A sucking sound at the site of injury is often observed in an open chest injury.
B is the answer to this question. For those who are not familiar with what Pneumothorax is, this actually means a collapsed lung. This can happen when the air that is supposed to stay in the lungs starts to leak and spread in between the lung and the chest wall. The air from the outside can push the lung until such time that it has already collapsed.
The man has sustained a strong and critical chest injury. The air pressure should be removed immediately so that the patient will be able to breathe. There are various methods for the air to be removed. The most common in inserting a tube to remove the pressure from time to time. In more severe cases wherein the air would need to be completely removed by surgery.
This client has sustained a blunt or a closed chest injury. Basic symptoms of a closed pneumothorax are shortness of breath and chest pain. A larger pneumothorax may cause tachypnea. cyanosis. diminished breath sounds. and subcutaneous emphysema. Hyperresonance also may occur on the affected side. A sucking sound at the site of injury would be noted with an open chest injury.
