🚨 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

🚨 NCLEX Sepsis Progression Guide: From SIRS to Septic Shock

🩸 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)

πŸ’‘ 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)

πŸ›‘ 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

πŸ§ͺ Order of interventions: Oβ‚‚ β†’ Blood cultures β†’ Broad antibiotics β†’ IV fluids β†’ Vasopressors

πŸ“ 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 βœ…

  • C. Increase fluids

  • D. Administer acetaminophen

Rationale: Unresponsive hypotension = septic shock, requiring vasopressors.

πŸ“Œ Summary

  • SIRS β†’ Sepsis β†’ Severe Sepsis β†’ Septic Shock

  • Recognize early signs of infection + systemic inflammation

  • Know which actions correspond to each stage

  • Timing of antibiotics, fluids, and vasopressors is crucial
