Relevant risk context includes major trauma. What is the most likely diagnosis? A. Severe diabetic ketoacidosis in ICU B. Cardiac tamponade after trauma C. Acute respiratory distress syndrome D. Multiorgan dysfunction syndrome E. Ventilator-associated pneumonia concern Show Answer & Explanation Correct Answer: C Explanation: The pattern of refractory hypoxemia with bilateral infiltrates with risk factors such as major trauma is most consistent with Acute respiratory distress syndrome. This answer best matches the expected diagnostic framework for Intensive Care. Reference: SCCM Critical Care Guidelines Comments & Discussion No comments yet. Be the first to comment!
