Question 1 Which of the following is the primary goal of Trauma Care After Resuscitation (TCAR)? A. Immediate surgical intervention for all trauma patients B. Optimization of patient outcomes after initial resuscitation C. Rapid discharge from the emergency department D. Elimination of all invasive monitoring Correct Answer: B Rationale: TCAR focuses on the critical period after initial resuscitation, emphasizing prevention of secondary injury, ongoing assessment, and optimization of recovery. Question 2 The leading cause of preventable death after successful trauma resuscitation is: A. Allergic reaction B. Secondary injury and physiologic deterioration C. Appendicitis D.
