Which vital sign indicates a need for immediate medical attention in a trauma patient?

• A. Heart rate over 100 BPM
• B. Systolic blood pressure less than 90 mmHg
• C. Temperature over 101°F
• D. Respiratory rate over 30 breaths per minute

Answer: (B)

The indication that a trauma patient requires immediate medical attention is a systolic blood pressure of less than 90 mmHg. This measurement is crucial as it often signifies hypovolemic shock, which can occur due to significant blood loss or severe trauma. When blood pressure drops below this threshold, it suggests that the body's circulatory system is compromised and may be unable to adequately perfuse vital organs. In trauma situations, maintaining adequate blood pressure is vital to ensure that oxygen and nutrients reach critical tissues. Therefore, a systolic blood pressure below 90 mmHg can be a warning sign of potential organ failure and the necessity for immediate intervention, such as fluid resuscitation or surgical intervention. Other vital signs, while important to monitor, may not indicate an immediate need for medical action in a trauma setting to the same extent. For instance, a heart rate over 100 BPM can happen in many situations, including anxiety or pain, and does not always indicate shock. A high respiratory rate can indicate stress or respiratory distress but may be a more secondary concern. A slight fever, while it can signal infection, is not an acute priority compared to severe hypotension in the context of trauma. Therefore, a systolic blood pressure under 90 mmHg stands
