## **Core Concept**
The sepsis screen, also known as the quick Sequential Organ Failure Assessment (qSOFA) or systemic inflammatory response syndrome (SIRS) criteria, is used to identify patients with sepsis early. It involves assessing various clinical parameters.

## **Why the Correct Answer is Right**
The correct answer, , is related to the components of sepsis screening. Common criteria include temperature (either >38°C or 90 beats per minute, tachypnea (respiratory rate >20 breaths per minute or PaCO2 12,000 cells/mm^3 or <4,000 cells/mm^3) or the presence of bands (immature white blood cells) are also considered. ## **Why Each Wrong Option is Incorrect** - **Option A:** This option might include temperature, which is a criterion for SIRS and sepsis screening. - **Option B:** This could represent heart rate, another criterion for SIRS and sepsis screening. - **Option D:** This might signify respiratory rate, also a part of SIRS and sepsis screening. ## **Clinical Pearl / High-Yield Fact** A key point to remember is that the early identification of sepsis is critical for patient outcomes. The use of qSOFA criteria (respiratory rate ≥22 breaths/min, altered mental status, and systolic blood pressure ≤100 mmHg) helps in quick identification. ## **Correct Answer:** .
