What vital sign is often an early indicator of sepsis in emergency patients?

• A. Elevated blood pressure
• B. Elevated heart rate
• C. Low respiratory rate
• D. Decreased temperature

Answer: (B)

Elevated heart rate is a key vital sign that indicates the body may be responding to an infection, making it an early indicator of sepsis in emergency patients. When the body is fighting an infection, it often increases heart rate in an attempt to maintain adequate blood flow and oxygen delivery to tissues. This physiological response, known as tachycardia, can occur even in the absence of other signs of infection. Monitoring heart rate is crucial in the emergency department, as it helps health professionals quickly identify patients who may be at risk for sepsis. Early recognition and intervention can significantly improve patient outcomes, as sepsis can rapidly progress to severe sepsis and septic shock. In contrast, elevated blood pressure is not typically a sign of early sepsis; rather, patients may exhibit low blood pressure as the condition progresses. A low respiratory rate is generally not indicative of sepsis; instead, patients might experience an increased respiratory rate due to metabolic demands during infection. Decreased temperature can also occur in sepsis, but fever is more commonly seen, making a drop in temperature a less reliable early indicator compared to an elevated heart rate.
