🦠 NCLEX Sepsis Guide: SIRS, Sepsis, Septic Shock & Nursing Priorities

Sepsis is a critical condition that rapidly progresses and requires immediate recognition and intervention. The NCLEX routinely tests this concept, especially in clinical judgment case studies involving deteriorating patients.

In this blog, we’ll break down:

• The progression of systemic infection

• Signs and symptoms at each stage

• NCLEX-level nursing actions

• Easy-to-follow KOTC visual infographic

🧬 Sepsis Progression Stages for NCLEX

Stage	Definition	Key Signs
SIRS	Inflammation from infection or injury	Fever, tachycardia, tachypnea, WBC shift
Sepsis	SIRS + suspected/confirmed infection	Same signs as SIRS, with a known source
Severe Sepsis	Sepsis with organ dysfunction	Hypotension, lactic acidosis, confusion
Septic Shock	Severe sepsis unresponsive to fluids	Requires vasopressors (e.g., norepinephrine)

💡 NCLEX Tip: Know which stage requires vasopressors and which stage needs cultures and fluids.

🧠 What Triggers Sepsis?

Common NCLEX case triggers include:

• Elderly UTI → confusion, fever, hypotension

• Pneumonia → hypoxia, increasing RR

• Surgical site infection → wound drainage, tachycardia

• Indwelling catheter → fever, chills, leukocytosis

🩺 Priority Interventions (In Order!)

1. Oxygen if hypoxic

2. Blood cultures x2 BEFORE antibiotics

3. Broad-spectrum antibiotics

4. IV fluids (NS or LR)

5. Vasopressors if hypotension persists

📝 NCLEX Sample Question

Q: A patient with suspected sepsis has a BP of 86/54 despite fluid bolus and continues to have altered mental status. What is the priority action?

• A. Continue fluids

• B. Recheck vitals in 30 minutes

• C. Administer vasopressors ✅

• D. Elevate head of bed

Rationale: This patient meets septic shock criteria and requires vasopressors urgently.

📌 Summary Reminders

• SIRS = early systemic inflammation

• Sepsis = SIRS + infection

• Severe Sepsis = organ dysfunction

• Septic Shock = unresponsive to fluids

Know the progression, symptoms, and timing of interventions.
