Verified step by step guidance

Understand the condition: Sepsis is a life-threatening response to infection that can lead to tissue damage, organ failure, and death. Severe sepsis involves organ dysfunction.

Recognize common physiological responses: In severe sepsis, the body often responds with increased heart rate (tachycardia) as it tries to maintain adequate blood flow to organs.

Consider the body's compensatory mechanisms: The heart rate increases to compensate for decreased blood pressure and to ensure that enough oxygen and nutrients are delivered to tissues.

Evaluate other symptoms: While hypothermia can occur, it is less common than fever. Decreased respiratory rate is not typical; instead, an increased rate is more common as the body attempts to meet oxygen demands.

Conclude with the most likely finding: Given the body's compensatory mechanisms in severe sepsis, an elevated heart rate is a common and expected assessment finding.
