What is a criterion defining adult major trauma victims?

• A. GCS less than 16
• B. Systolic blood pressure less than 90
• C. Respiratory rate below 15
• D. Age over 60

Answer: (B)

The criterion that defines adult major trauma victims is a systolic blood pressure less than 90. This threshold is critical because it indicates significant hemorrhagic shock or cardiovascular compromise, which are common in cases of major trauma. A systolic blood pressure below this level suggests that the body is not adequately perfusing vital organs, placing the individual at a high risk of severe injury or death. In trauma assessments, monitoring blood pressure is vital and often serves as a baseline indicator of the patient's hemodynamic stability. When a patient presents with a systolic blood pressure under 90, it prompts urgent intervention and evaluation, as it reflects critical instability and the need for immediate medical attention. Other options, while important indicators in the context of trauma assessments, do not independently signify major trauma. For example, a Glasgow Coma Scale (GCS) score less than 16 could indicate neurological impairment but does not solely define major trauma without considering other factors. Similarly, a respiratory rate below 15 may demonstrate respiratory distress but does not correlate directly with the severity of trauma on its own, and being over 60 raises the risk factors for complications without directly classifying the trauma event.
