🚨 NCLEX Sepsis Progression Guide: From SIRS to Septic Shock

Sepsis is one of the most high-stakes, high-yield concepts tested on the NCLEX. You’re expected to recognize early warning signs, understand the progression of systemic infection, and know what critical interventions to take at each stage.

This blog will break down:

• The four clinical stages of sepsis

• Nursing priorities for each step

• NCLEX practice cues and red flags

• A visual guide to sepsis progression

🩸 Stages of Sepsis & Clinical Signs

Stage	Definition	Clinical Signs
SIRS	Systemic inflammatory response	Fever, tachycardia, tachypnea, WBC shift
Sepsis	SIRS + suspected or confirmed infection	Infection source + SIRS signs
Severe Sepsis	Sepsis + organ dysfunction	Hypotension, lactic acidosis, altered mental status
Septic Shock	Severe sepsis unresponsive to fluids	Requires vasopressors (e.g., norepinephrine)

💡 NCLEX Tip: Know that blood cultures must be drawn before giving antibiotics.

🧠 Sepsis Mnemonic: "Time" to Act

T – Temperature abnormal (high or low)
I – Infection (confirmed or suspected)
M – Mental decline (confused, sleepy, difficult to rouse)
E – Extremely ill (dyspnea, mottled skin, low BP)

🛑 Nursing Interventions by Stage

Stage	Top NCLEX Action
SIRS	Monitor vitals and labs
Sepsis	Start fluids + blood cultures + antibiotics
Severe Sepsis	Administer oxygen and assess for organ failure
Septic Shock	Initiate vasopressors and escalate to ICU

🧪 Order of interventions: O₂ → Blood cultures → Broad antibiotics → IV fluids → Vasopressors

📝 NCLEX Practice Question

Q: A patient has fever, tachycardia, and confirmed pneumonia. BP is 84/56 despite 2L NS. What is the nurse's priority?

• A. Call lab

• B. Start vasopressors ✅

• C. Increase fluids

• D. Administer acetaminophen

Rationale: Unresponsive hypotension = septic shock, requiring vasopressors.

📌 Summary

• SIRS → Sepsis → Severe Sepsis → Septic Shock

• Recognize early signs of infection + systemic inflammation

• Know which actions correspond to each stage

• Timing of antibiotics, fluids, and vasopressors is crucial
