Final answer:
The patient's total revised trauma score is 9.
Step-by-step explanation:
The patient's total revised trauma score is 9.
The total revised trauma score (TRTS) is calculated by assigning points based on the patient's Glasgow Coma Scale (GCS) score, respiratory rate, and systolic blood pressure. In this case, the GCS score is 10, which assigns 4 points, the respiratory rate is 30/min, which assigns 3 points, and the systolic blood pressure is 78, which assigns 2 points.
Adding up the points, 4 + 3 + 2 = 9, so the patient's total revised trauma score is 9.
