Surgery EOR Exam PA Easy Questions and Answers 100% Correct A 54-year-old man presents to the emergency department with crampy abdominal pain, nausea, and vomiting. The patient has not passed gas or had a bowel movement for at least 10 hours. On examination, the abdomen is distended and there are high-pitched bowel sounds with rushes. A plain radiograph of the abdomen reveals cecal distension to 12 cm. What is the most appropriate definitive management for this patient? A Intravenous fluids B Nasogastric suction C Observation D Surgical exploration - Answer- The Correct Answer is: D Massive distention of the cecum, as detected on plain radiograph, is typically seen in "closed loop" obstructions where the ileocecal valve is competent. When distention approaches 12 cm, there is an increased risk of perforation and/or gangrene. Expedient surgical intervention is indicated. Although observation with intravenous fluids and nasogastric decompression are important adjuncts to management, surgical exploration is the only way to rapidly address this emergent situation. When a bone is fractured, there are the 3 stages of healing. What is the proper order in which the healing occurs? A Inflammatory, Remodeling, Reparative B Inflammatory, Reparative, Remodeling C Remodeling, Inflammatory, Reparative D Remodeling, Reparative, Inflammatory E Reparative, Inflammatory, Remodeling - Answer- The Correct Answer is: B Inflammatory changes happen after fractures and this is followed by a reparative phase and ultimately, a remodeling phase. The healing from acute injuries generally starts with inflammation,. Once the integrity of the bone has been restored on the macro level, bone remodeling continues until full healing has occurred. What is the most common embolic source of acute arterial occlusion in the lower extremities? A Atrial fibrillation B Aortic aneurysm C Myocardial infarction D Prosthetic cardiac valve E Iliac artery thrombus - Answer- The Correct Answer is: A The heart accounts for 80% of all emboli, with atrial fibrillation making up 70% of that. Aortic aneurysms are frequently lined with thrombus but infrequently embolize; aneurysmal disease only accounts for 6% of all acute arterial occlusion. Acute myocardial infarction (especially those associated with left ventricular thrombus) accounts for 25% of cardioembolism, with peripheral embolization often the first sign of a previously "silent" MI. Prosthetic cardiac valves make up a still small but increasingly prevalent source of emboli. Peripheral arterial thrombi account for only 3% of acute occlusion. Following emergent appendectomy, a 58-year-old obese male develops a temperature of 102.4˚F, 18 hours postoperatively. His respiratory rate is 26 and his pulse is 116bpm. A physical exam reveals scattered fine rales. What is the
