Relevant risk context includes delayed source control. What is the most likely diagnosis? A. Multiorgan dysfunction syndrome B. Septic shock C. Severe diabetic ketoacidosis in ICU D. Cardiac tamponade after trauma E. Acute respiratory distress syndrome Show Answer & Explanation Correct Answer: D Explanation: The pattern of hypotension with distended neck veins and muffled heart sounds with risk factors such as delayed source control is most consistent with Cardiac tamponade after trauma.
