**Core Concept**
Sepsis is a life-threatening condition arising from the body's response to an infection, characterized by an uncontrolled inflammatory response. In the intensive care unit (ICU), managing sepsis requires a multi-faceted approach, including early recognition, fluid resuscitation, antimicrobial therapy, and hemodynamic support.

**Why the Correct Answer is Right**
The Surviving Sepsis Campaign guidelines recommend early goal-directed therapy (EGDT), which involves rapid fluid resuscitation to restore adequate blood pressure and cardiac output. This is based on the pathophysiological principle that sepsis-induced hypotension is often due to vasodilation and decreased cardiac output. The goal of EGDT is to restore these parameters to a normal range within the first 6 hours of treatment. This approach has been shown to improve outcomes in patients with sepsis.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not incorrect, as early fluid resuscitation is a cornerstone of sepsis management and is supported by evidence.
**Option B:** This option is not incorrect, as vasopressor therapy is often necessary to support blood pressure in patients with sepsis who remain hypotensive despite fluid resuscitation.
**Option C:** This option is not incorrect, as source control, such as surgical drainage of an abscess or removal of a central line, is critical in managing sepsis.

**Clinical Pearl / High-Yield Fact**
The "SEPSIS" acronym can be used to remember the key components of sepsis management: S - Shock, E - Early recognition, P - Prompt fluid resuscitation, S - Source control, I - Infection control, S - Supportive care.

**Correct Answer:** D

✓ Correct Answer: C. Intensive blood glucose monitoring and prevention of hyperglycemia improves survival in critically ill patients
