A 56-year-old man is brought to the emergency department 25 minutes after he was involved in a high-speed motor vehicle collision where he was the unrestrained passenger. He has severe lower abdominal and pelvic pain. On arrival, he is alert and oriented. His pulse is 95/min, respirations are 22/min, and blood pressure is 106/62 mm Hg. Examination shows severe tenderness to palpation over the lower abdomen and over the left anterior superior iliac spine. There is no limb length discrepancy. Application of downward pressure over the pelvis shows no springy resistance or instability. Rectal examination is unremarkable. A focused assessment with sonography shows no free fluid in the abdomen. There is no blood at the urethral meatus. Placement of a Foley catheter shows gross hematuria. An x-ray of the pelvis shows a fracture of the left pelvic edge. Which of the following is the most appropriate next step in management?
AIntravenous pyelography
BExternal fixation of the pelvis
CCystoscopy
DRetrograde urethrography
ERetrograde cystography
A 50-year-old male presents to the emergency with abdominal pain. He reports he has had abdominal pain associated with meals for several months and has been taking over the counter antacids as needed, but experienced significant worsening pain one hour ago in the epigastric region. The patient reports the pain radiating to his shoulders. Vital signs are T 38, HR 120, BP 100/60, RR 18, SpO2 98%. Physical exam reveals diffuse abdominal rigidity with rebound tenderness. Auscultation reveals hypoactive bowel sounds. Which of the following is the next best step in management?
AAdmission and observation
BChest radiograph
C12 lead electrocardiogram
DAbdominal CT scan
EAbdominal ultrasound
A 41-year-old man is admitted to the emergency room after being struck in the abdomen by a large cement plate while transporting it. On initial assessment by paramedics at the scene, his blood pressure was 110/80 mm Hg, heart rate 85/min, with no signs of respiratory distress. On admission, the patient is alert but in distress. He complains of severe, diffuse, abdominal pain and severe weakness. Vital signs are now: blood pressure 90/50 mm Hg, heart rate 96/min, respiratory rate 19/min, temperature 37.4℃ (99.3℉), and oxygen saturation of 95% on room air. His lungs are clear on auscultation. The cardiac exam is significant for a narrow pulse pressure. Abdominal examination reveals a large bruise over the epigastric and periumbilical regions. The abdomen is distended and there is diffuse tenderness to palpation with rebound and guarding, worst in the epigastric region. There is hyperresonance to percussion in the epigastric region and absence of hepatic dullness in the right upper quadrant. Aspiration of the nasogastric tube reveals bloody contents. Focused assessment with sonography for trauma (FAST) shows free fluid in the pelvic region. Evaluation of the perisplenic and perihepatic regions is impossible due to the presence of free air. Aggressive intravenous fluid resuscitation is administered but fails to improve upon the patient’s hemodynamics. Which of the following is the next best step in management?
AEmergency laparoscopy
BAbdominal ultrasound
CDiagnostic peritoneal lavage (DPL)
DEmergency laparotomy
ECT scan
