Sepsis Screening (qSOFA, SIRS Criteria) | ca-rn-nclex-rn | NurseNest

Clinical Meaning

Sepsis is a life threatening organ dysfunction caused by a dysregulated host response to infection.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. The immune system's overactivation triggers a cascade of inflammatory mediators (TNF-α, IL-1, IL-6), endothelial damage, microvascular thrombosis, and tissue hypoperfusion leading to progressive organ failure. Screening Tools: 1. SIRS Criteria (Systemic Inflammatory Response Syndrome): ≥2 of the following: • Temperature >38°C (100.4°F) OR <36°C (96.8°F) • Heart rate >90 bpm • Respiratory rate >20/min OR PaCO2 <32 mmHg • WBC >12,000 OR <4,000 OR >10% bands (immature neutrophils) SIRS is SENSITIVE but not SPECIFIC: many conditions trigger SIRS without infection. 2. qSOFA (Quick Sequential Organ Failure Assessment): ≥2 of: • Respiratory rate ≥22/min • Altered mentation (any change from baseline) • Systolic blood pressure ≤100 mmHg qSOFA is a bedside screening tool: it does NOT require lab work. Score ≥2 should trigger a full sepsis workup and SOFA calculation. 3. SOFA Score (Sequential Organ Failure Assessment): Assesses 6 organ systems (respiratory, coagulation, liver, cardiovascular, CNS, renal) with scores 0-4 each. An acute increase of ≥2 points from baseline in the setting of known/suspected infection = Sepsis....

Clinical reasoning

For Sepsis Screening (Qsofa, SIRS Criteria), connect the assessment cue to the immediate risk before selecting an action for RN. Start with stability, ABCs, neurologic change, medication risk, infection risk, and scope of practice. Then decide whether the safest next step is assess, intervene, escalate, teach, or evaluate response.

Patient safety implications

A missed priority in Sepsis Screening (Qsofa, SIRS Criteria) can delay recognition of deterioration or allow preventable harm to continue. Protect the client first by verifying abnormal cues, using ordered precautions, escalating unstable findings, and reassessing after intervention.

Example application

In a Sepsis Screening (Qsofa, SIRS Criteria) item, explain the first cue you noticed, the complication it predicts, the nursing action within scope, and the finding that proves the response worked.
