Which vital signs indicate a trauma alert in adults?

The answer highlights crucial vital signs that prompt a trauma alert in adults. A systolic blood pressure of less than 90 mmHg is a critical indicator of potential shock, which can arise from severe injury or blood loss. This low blood pressure suggests inadequate perfusion to vital organs, requiring immediate medical attention. Moreover, abnormal respiratory rates reflect the body's response to trauma; a respiratory rate of less than 10 breaths per minute or greater than 29 breaths per minute indicates respiratory failure or significant distress, both of which are serious concerns in trauma scenarios.

The other choices do not meet the criteria for a trauma alert. A pulse rate under 60 beats per minute and high blood glucose levels may indicate various health issues but are not specific indicators of acute trauma. The combination of a body temperature above 101°F and a blood pressure reading above 120/80 mmHg presents values that may not signify an immediate trauma alert. Lastly, a respiratory rate that falls within the normal range of 12 to 20 breaths per minute, coupled with a standard blood pressure reading, typically lacks the urgency required to flag a trauma alert. In summary, option A correctly identifies the vital signs that necessitate a trauma alert due to their association with life-threatening conditions following trauma.
