Radtech Simulation Examination 3

1. The person accredited with the initial descovery of x ray is

Dr. Otto Walkhoff

William D. Coolidge

Wilhelm Conrad Roentgen

Thomas alva Edison

Dr. C. Edmond Kells

Wilhelm Conrad Roentgen is credited with the initial discovery of X-rays. In 1895, while conducting experiments with cathode rays, Roentgen noticed a fluorescent glow coming from a nearby screen. He deduced that this glow was caused by a new type of ray that was being emitted from the cathode tube. Roentgen called these rays "X-rays" due to their unknown nature. He went on to conduct further experiments and published his findings, which revolutionized the field of medicine and led to the development of X-ray imaging technology.

This can occur due to trauma or injury to the chest, causing blood vessels to rupture and bleed into the pleural space. Symptoms of a hemothorax may include chest pain, difficulty breathing, and decreased breath sounds on the affected side. Treatment typically involves draining the blood from the pleural cavity and addressing the underlying cause of the bleeding.
