Abdominal compartment syndrome — MCQs

A 67-year-old woman has fallen from the second story level of her home while hanging laundry. She was brought to the emergency department immediately and presented with severe abdominal pain. The patient is anxious, and her hands and feet feel very cold to the touch. There is no evidence of bone fractures, superficial skin wounds, or a foreign body penetration. Her blood pressure is 102/67 mm Hg, respirations are 19/min, pulse is 87/min, and temperature is 36.7°C (98.0°F). Her abdominal exam reveals rigidity and severe tenderness. A Foley catheter and nasogastric tube are inserted. The central venous pressure (CVP) is 5 cm H2O. The medical history is significant for hypertension. Which of the following is best indicated for the evaluation of this patient?

Ten days after undergoing emergent colectomy for a ruptured bowel that she sustained in a motor vehicle accident, a 59-year-old woman has abdominal pain. During the procedure, she was transfused 3 units of packed red blood cells. She is currently receiving total parenteral nutrition. Her temperature is 38.9°C (102.0°F), pulse is 115/min, and blood pressure is 100/60 mm Hg. Examination shows tenderness to palpation in the right upper quadrant of the abdomen. Bowel sounds are hypoactive. Serum studies show: Aspartate aminotransferase 142 U/L Alanine aminotransferase 86 U/L Alkaline phosphatase 153 U/L Total bilirubin 1.5 mg/dL Direct bilirubin 1.0 mg/dL Amylase 20 U/L Which of the following is the most likely diagnosis?

A 35-year-old man is brought to the emergency department from a kitchen fire. The patient was cooking when boiling oil splashed on his exposed skin. His temperature is 99.7°F (37.6°C), blood pressure is 127/82 mmHg, pulse is 120/min, respirations are 12/min, and oxygen saturation is 98% on room air. He has dry, nontender, and circumferential burns over his arms bilaterally, burns over the anterior portion of his chest and abdomen, and tender spot burns with blisters on his shins. A 1L bolus of normal saline is administered and the patient is given morphine and his pulse is subsequently 80/min. A Foley catheter is placed which drains 10 mL of urine. What is the best next step in management?

A 23-year-old patient presents to the emergency department after a motor vehicle accident. The patient was an unrestrained driver involved in a head-on collision. The patient is heavily intoxicated on what he claims is only alcohol. An initial trauma assessment is performed, and is notable for significant bruising of the right forearm. The patient is in the trauma bay, and complains of severe pain in his right forearm. A physical exam is performed and is notable for pallor, decreased sensation, and cool temperature of the skin of the right forearm. Pain is elicited upon passive movement of the right forearm and digits. A thready radial pulse is palpable. A FAST exam is performed, and is negative for signs of internal bleeding. The patient's temperature is 99.5°F (37.5°C), pulse is 100/min, blood pressure is 110/70 mmHg, respirations are 12/min, and oxygen saturation is 98% on room air. Radiography of the right forearm is ordered. The patient is still heavily intoxicated. Which of the following is the best next step in management?

A 43-year-old man is brought to the emergency department 30 minutes after falling from the roof of a construction site. He reports abdominal and right-sided flank pain. His temperature is 37.1°C (98.8°F), pulse is 114/min, and blood pressure is 100/68 mm Hg. Physical examination shows numerous ecchymoses over the trunk and flanks and a tender right abdomen without a palpable mass. Focused assessment with sonography for trauma (FAST) shows no intraperitoneal fluid collections. His hemoglobin concentration is 7.6 g/dL. The most likely cause of his presentation is injury to which of the following organs?

A 27-year-old-man is brought to the emergency department 30 minutes after being involved in a motorcycle accident. He lost control at high speed and was thrown forward onto the handlebars. On arrival, he is alert and responsive. He has abdominal pain and superficial lacerations on his left arm. Vital signs are within normal limits. Examination shows a tender, erythematous area over his epigastrium. The abdomen is soft and non-distended. A CT scan of the abdomen shows no abnormalities. Treatment with analgesics is begun, the lacerations are cleaned and dressed, and the patient is discharged home after 2 hours of observation. Four days later, the patient returns to the emergency department with gradually worsening upper abdominal pain, fever, poor appetite, and vomiting. His pulse is 91/min and blood pressure is 135/82 mm Hg. Which of the following is the most likely diagnosis?

A 68-year-old male with past history of hypertension, hyperlipidemia, and a 30 pack/year smoking history presents to his primary care physician for his annual physical. Because of his age and past smoking history, he is sent for screening abdominal ultrasound. He is found to have a 4 cm infrarenal abdominal aortic aneurysm. Surgical repair of his aneurysm is indicated if which of the following are present?

A 36-year-old man comes to the emergency department 4 hours after a bike accident for severe pain and swelling in his right leg. He has not had a headache, nausea, vomiting, abdominal pain, or blood in his urine. He has a history of gastroesophageal reflux disease and allergic rhinitis. He has smoked one pack of cigarettes daily for 17 years and drinks an average of one alcoholic beverage daily. His medications include levocetirizine and pantoprazole. He is in moderate distress. His temperature is 37°C (98.6°F), pulse is 112/min, and blood pressure is 140/80 mm Hg. Examination shows multiple bruises over both lower extremities and the face. There is swelling surrounding a 2 cm laceration 13 cm below the right knee. The lower two-thirds of the tibia is tender to palpation and the skin is pale and cool to the touch. The anterior tibial, posterior tibial, and dorsalis pedis pulses are weak. Capillary refill time of the right big toe is 4 seconds. Dorsiflexion of his right foot causes severe pain in his calf. Cardiopulmonary examination is normal. An x-ray is ordered, which is shown below. Which of the following is the most appropriate next step in management?

A 35-year-old man is referred to a physical therapist due to limitation of movement in the wrist and fingers of his left hand. He cannot hold objects or perform daily activities with his left hand. He broke his left arm at the humerus one month ago. The break was simple and treatment involved a cast for one month. Then he lost his health insurance and could not return for follow up. Only after removing the cast did he notice the movement issues in his left hand and wrist. His past medical history is otherwise insignificant, and vital signs are within normal limits. On examination, the patient’s left hand is pale and flexed in a claw-like position. It is firm and tender to palpation. Right radial pulse is 2+ and left radial pulse is 1+. The patient is unable to actively extend his fingers and wrist, and passive extension is difficult and painful. Which of the following is a proper treatment for the presented patient?

Three hours later, the patient is reassessed. Her right arm is put in an elevated position and physical examination of the extremity is performed. The examination reveals reduced capillary return and peripheral pallor. Pulse oximetry of her right index finger on room air shows an oxygen saturation of 84%. Which of the following is the most appropriate next step in management?
