An 8-year-old 2/N cocker spaniel was presented to an emergency clinic for lethargy, anorexia, and abdominal distention from a fall from a two-story window 7 days ago. The dog initially presented to the clinic for ascites with a balloted fluid wave and dyspnea. The acute hemoabdomen was resolved with an abdominal exploratory to control
bleeding from the liver and spleen. Hemorrhaging was controlled at that time, and blood was suctioned from the abdomen. The dog also received a blood transfusion. Upon arriving at the clinic today it was noted on PE that the dog had pale pink mm, prolonged CRT, and was tachypnic and dyspneic. A chest radiograph revealed pneumothorax as the cause of tachypnea and dyspnea. A chest tube was placed in the dog pending surgical repair of the chest. 2/N lethargy anorexia abdominal distention ascites balloted dyspnea acute hemoabdomen abdominal exploratory transfusion PE mm CRT tachypnic chest radiograph pneumothorax chest tube What will be an ideal response?
