NGN Sepsis Case Study: Recognize Cues and Prioritize Care
Sepsis questions test whether you can connect scattered patient data into one urgent clinical picture. The safest answer is rarely based on one isolated lab value — you need to recognize the pattern.
On the NCLEX, sepsis reasoning means recognizing a pattern: infection, worsening perfusion, organ dysfunction, and the need for rapid escalation. This NGN-style case uses the NCSBN Clinical Judgment Measurement Model (NCJMM), often shortened in study materials to CJMM — recognize cues, analyze cues, prioritize hypotheses, generate solutions, take action, and evaluate outcomes. It is one example in the NGN case studies series, and each case is built around the six steps described in the clinical judgment framework.
Educational NCLEX case, not a clinical protocol
This page is for NCLEX study. It is not a clinical protocol and does not replace facility policy, provider orders, sepsis pathways, or current clinical guidelines. Always practice within your scope and follow local orders.
Case objective
By the end of this case, you should be able to:
- Identify sepsis cues in a chart-style scenario
- Distinguish uncomplicated infection from suspected sepsis with organ dysfunction
- Recognize signs of hypoperfusion
- Choose priority nursing actions within the nurse's scope
- Avoid common NCLEX traps in sepsis questions
- Evaluate whether the client is improving or deteriorating
Before you start: sepsis wording matters
Older nursing materials often taught sepsis as "SIRS plus infection." That wording is too simple for modern practice and should not be the main way you reason about sepsis. For NCLEX reasoning, think this way:
- Infection means there is a suspected or confirmed source, such as a urinary tract infection or pneumonia.
- Sepsis means infection is associated with life-threatening organ dysfunction.
- Septic shock is a more severe subset involving profound circulatory and metabolic abnormalities. In practice, shock status depends on response to fluids, vasopressor need, lactate, and the clinical picture.
SIRS findings such as fever, tachycardia, tachypnea, and an abnormal WBC count are still important warning signs. But SIRS findings alone do not equal sepsis.
Patient chart exhibit
Emergency department nursing note
Margaret Chen is a 68-year-old female brought to the emergency department by ambulance. Her daughter found her confused, lethargic, and unable to get out of bed.
The daughter reports that the client has had urinary frequency, urgency, and burning for 3 days. The client refused to seek care earlier. Today, she became increasingly disoriented.
At baseline, the client lives alone, is independent with activities of daily living, and is alert and oriented x4.

Laboratory and diagnostic data
| Finding | Result | Why it matters |
|---|---|---|
| WBC | 18,200/mm³ | Supports infectious / inflammatory response |

Question 1 — Recognize cues
Which findings are clinically significant cues in this case? Select all that apply.
- ATemperature 102.8°F / 39.3°C
- BHeart rate 118/min
- CBlood pressure 88/56 mmHg
- DOxygen saturation 91% on room air
- EOriented to person only
- FHistory of osteoarthritis
- GLactate 4.2 mmol/L
- HUrinalysis positive for nitrites, leukocyte esterase, and bacteria
- IUrine output 20 mL dark amber urine
- JSulfonamide antibiotic allergy
Correct answers: A, B, C, D, E, G, H, I, J.
The priority cues are the findings that point to infection, hypoperfusion, organ dysfunction, or immediate medication safety. The fever, tachycardia, hypotension, tachypnea, low oxygen saturation, acute confusion, elevated lactate, low urine output, and positive urinalysis create a high-risk sepsis pattern. The sulfonamide allergy matters because antibiotics are time-sensitive and allergy safety must be verified before administration. Osteoarthritis is part of the history but does not explain the acute deterioration.
Question 2 — Analyze cues
Classify each finding.
| Finding | Best interpretation |
|---|---|
| Positive nitrites, leukocyte esterase, bacteria | Infection source |
| Lactate 4.2 mmol/L | Tissue hypoperfusion |
| Creatinine 1.8 mg/dL and oliguria | Organ dysfunction / renal perfusion concern |
| Confusion from baseline x4 to person only | Acute neurologic change / possible poor perfusion |
| Blood pressure 88/56 mmHg | Hemodynamic instability |
| Sulfonamide antibiotic allergy | Medication-safety cue |
| Recurrent UTIs and diabetes | Risk factors |
Rationale. The key is to connect the findings. This is not just a urinary tract infection. The client has evidence of systemic illness, poor perfusion, and organ dysfunction. The urinary findings help identify the likely source. The lactate, hypotension, altered mental status, oliguria, thrombocytopenia, and kidney-function changes make the case urgent.
Question 3 — Prioritize hypotheses
Which hypothesis is the highest priority?
- AUncomplicated urinary tract infection
- BSuspected sepsis from urinary source with hypoperfusion and organ dysfunction
- COsteoarthritis flare causing immobility
- DMild dehydration from poor oral intake
Correct answer: B.
The client likely has a urinary source of infection, but the presentation is not uncomplicated. Hypotension, elevated lactate, acute mental status change, oliguria, delayed capillary refill, thrombocytopenia, and kidney dysfunction raise concern for sepsis with hypoperfusion and organ dysfunction. Dehydration may be contributing, but it does not explain the full pattern. Osteoarthritis is not the priority.
Question 4 — Generate solutions
Which nursing actions are appropriate to anticipate or initiate according to protocol and provider orders? Select all that apply.
- AApply supplemental oxygen and reassess work of breathing
- BActivate the sepsis pathway, rapid response, or notify the provider early
- CEstablish IV access for fluids and medications
- DObtain blood cultures and other ordered cultures before antibiotics if this does not delay therapy
- EAdminister prescribed broad-spectrum IV antibiotics promptly
- FBegin ordered isotonic crystalloid fluid resuscitation and monitor response
- GMonitor urine output, mental status, blood pressure, oxygenation, and lactate trend
- HGive oral antibiotics and discharge the client with follow-up instructions
- IHold all interventions until a CT scan confirms the source
- JClarify medication orders for metformin and lisinopril because kidney dysfunction and hypotension are present
Correct answers: A, B, C, D, E, F, G, J.
This client needs rapid nursing response, early escalation, oxygen support, IV access, cultures when feasible, prompt ordered antibiotics, ordered fluid resuscitation, and close reassessment. Oral antibiotics and discharge are unsafe for this presentation. Diagnostic tests should not delay treatment of life-threatening deterioration. Home medications may need to be held or adjusted, but the nurse should follow protocol and provider orders rather than independently discontinuing them.
Question 5 — Take action
Place the actions in the best priority order.
Rationale. The first priority is immediate stabilization and recognition of deterioration. Because the client is hypotensive, hypoxic, confused, and has elevated lactate, escalation should occur early — not after every task is completed. Cultures are preferred before antibiotics when feasible, but antibiotics should not be delayed for difficult culture collection in a high-risk sepsis presentation. Fluids and antibiotics are time-sensitive, and the nurse must reassess response continuously.
Question 6 — Evaluate outcomes
One hour after initial interventions, the nurse reviews updated data.
| Finding | Result |
|---|---|
| Blood pressure | 96/60 mmHg |
| Heart rate | 108/min |
| Respiratory rate | 22/min |
| Oxygen saturation | 95% on 2 L nasal cannula |
| Mental status | Still confused, now follows simple commands |
| Urine output | 25 mL in the past hour |
| Lactate | Repeat pending |
Which interpretation is best?
- AThe client has fully stabilized and can be transferred to a medical-surgical unit.
- BThe client shows partial improvement but still needs close monitoring and possible escalation.
- CThe client is worsening because the heart rate is still above 100/min.
- DThe client no longer needs sepsis treatment because oxygen saturation improved.
Correct answer: B.
The oxygen saturation and blood pressure have improved, and the client is following simple commands. However, the client remains tachycardic, confused, and oliguric. This is partial improvement, not full stabilization. The nurse should continue close monitoring, trend lactate when available, reassess perfusion, monitor urine output, and prepare for escalation if hypotension or hypoperfusion persists.
Common NCLEX traps in sepsis cases
Trap 1: Treating the case as a simple UTI
Urinary symptoms explain the source, but the priority is the systemic deterioration. Confusion, hypotension, lactate elevation, oliguria, and delayed capillary refill move the question beyond routine UTI care.
Trap 2: Using SIRS as the final answer
Fever, tachycardia, tachypnea, and leukocytosis matter, but do not stop there. Look for organ dysfunction and perfusion problems.
Trap 3: Waiting for every diagnostic result
Do not delay urgent nursing response while waiting for nonessential testing. In high-risk sepsis presentations, early recognition, escalation, oxygen, IV access, ordered cultures, antibiotics, fluids, and reassessment are the priority.
Trap 4: Forgetting allergies
Antibiotics are time-sensitive, but allergy verification still matters. The nurse should verify allergy history and administer the prescribed antibiotic safely.
Trap 5: Ignoring urine output
Low urine output in this case is not just a hydration detail. It may signal renal hypoperfusion and organ dysfunction.
Trap 6: Calling shock “confirmed” too early
The client has high concern for sepsis-induced hypoperfusion and possible septic shock. Shock classification depends on the full clinical picture, response to fluid resuscitation, lactate, and vasopressor requirement.

Practice NGN case studiesHow to keep practicing
For NGN case studies, do not memorize the answer pattern. Practice the thinking pattern. After each case, ask: which cues mattered most, which cue changed the priority, did I identify organ dysfunction, did I choose nursing actions or medical orders beyond the nurse's role, did I reassess the right outcomes, and did I escalate early enough? The NCLEX question types overview explains the highlight, matrix, and ordered-response formats this case uses, and a structured NCLEX study plan helps you turn case practice into a routine.

Review the NGN format guideKey takeaway
In sepsis questions, the NCLEX is testing whether you can recognize deterioration early. The pattern to notice is suspected infection, an acute change from baseline, poor perfusion, organ dysfunction, and the need for rapid escalation and reassessment. Safe nursing judgment means acting early, communicating clearly, following orders and protocols, and evaluating whether the client is improving.
