ECG: ST ELEVATION V2–V5 · Tombstone morphology · STEMI confirmed

Cardiac Anatomy — LAD Occlusion
What's Happening
The Left Anterior Descending (LAD) artery is blocked by a ruptured atherosclerotic plaque. The anterior wall of the left ventricle — the heart's main pumping chamber — is dying from ischemia. Every minute without reperfusion = ~2 million myocardial cells lost.
Why BP is 92/58
Anterior wall dysfunction reduces ejection fraction → cardiac output drops → compensatory tachycardia → if untreated, cardiogenic shock within minutes. This is why NTG is contraindicated — further vasodilation with a failing pump = cardiac arrest.
ECG — V2–V5 Leads
V2–V5 look directly at the anterior LV wall — LAD territory. ST elevation here = transmural ischemia. Tombstone morphology = most severe pattern. Cath lab within 90 min from first medical contact is the survival window.

Clinical Presentation
Mr. David Osei, 58M, presented with "indigestion" at 0832. Now: crushing chest pressure 8/10, radiating to jaw and left arm, profuse diaphoresis, nausea. ECG: ST elevation ≥2mm in V2–V5. BP 92/58 and falling. The attending is in another room with a trauma code.
| Parameter | Value | Normal | Significance |
|---|---|---|---|
| HR | 112 bpm ↑ | 60–100 | Compensatory tachycardia — cardiogenic shock evolving |
| BP | 92/58 mmHg ↓↓ | ≥90/60 | Hypotension — Killip Class II/III borderline |
| SpO2 | 94% RA | ≥95% | Supplemental O2 indicated if <94% — NTG caution with hypotension |
| ECG | STE V2–V5 | Isoelectric | STEMI: anterior wall — LAD territory — CATH LAB NOW |
| Troponin I | Pending | <0.04 ng/mL | Don't wait — treatment based on ECG |
| Pain | 8/10 | 0 | Refractory to nitroglycerin — BP too low for NTG |
Critical Teaching Point — STEMI Trap
BP 92/58 is a CONTRAINDICATION to nitroglycerin. Many nurses give NTG reflexively for chest pain — this is the key pharmacology decision in this node. Expert pattern: morphine + aspirin + O2 positioning + CATH LAB activation simultaneously.
Decision S1-A-01 · Immediate STEMI Response · D-05 CRITICAL
The attending is occupied. Mr. Osei is diaphoretic, BP dropping. What are your first three actions?
COGNITA: Parallel action capacity · NTG contraindication recognition · Cath lab call without physician permission
A
Give morphine IV for pain and administer SL nitroglycerin for the chest pressure. Hold aspirin until allergy history is confirmed — the ECG changes could represent demand ischaemia.
D-06 CRITICAL GAP: Morphine worsens ACS outcomes. NTG contraindicated at SBP 92. Two pharmacology safety errors at once.
B
Give aspirin 325mg, apply O2 at 2L, page attending stat for STEMI review. Do not activate cath lab independently — await physician confirmation before any irreversible escalation.
D-05 ADEQUATE: Correct partial actions. Cath lab deferred pending physician instruction. Permission-seeking pattern. Time lost.
C
Give aspirin 325mg, O2 at 2L NC, activate cath lab per ECG criteria — no physician required. Page attending simultaneously. NTG is contraindicated at SBP 92.
D-05 + D-06 EXPERT: Parallel activation. Cath lab called independently. NTG contraindication recognised. Top pattern.
D
Recheck vitals and reassess before acting. He arrived ambulatory and talked through triage, suggesting the situation may be less urgent than the ECG pattern indicates. Repeat V4–V6 leads.
D-08 GAP: Ambulatory presentation does not reduce STEMI urgency. ECG criteria are definitive. 10-min delay costs ~20 million myocardial cells.

Clinical Consequence
Consequence · 4 minutes later — Dr. Martinez arrives at bedside
Dr. Martinez: "Why isn't he in the cath lab already? The door-to-balloon clock started at 0832." The cath lab team calls back — they need a verbal physician order to proceed. What do you say to expedite this?
A
Tell Dr. Martinez the cath lab team is on hold and hand over the chart — it is now the physician's responsibility to move this forward and contact the cath lab directly.
D-07 GAP: No SBAR delivered. Physician unprepared. Chart review adds 2–3 minutes. Cath lab clock continues running.
B
SBAR: STEMI V2–V5, BP 92/58, aspirin given, O2 on, NTG held for hypotension. Cath lab needs your verbal order now. Chart ready — hand it simultaneously.
D-07 EXPERT: Complete rapid SBAR. Physician empowered for immediate decision. Chart pre-prepared. Door-to-balloon minimised.
C
Tell Dr. Martinez: 'Mr. Osei, 58M, STEMI V2–V5, low BP, aspirin given, O2 running.' Hand over the chart for him to review first, then step back while he calls the cath lab.
D-07 ADEQUATE: S + B present. No assessment, no explicit recommendation. One more exchange needed. ~1 min lost.
D
Apologise for not having the verbal order ready before Dr. Martinez arrived, then suggest he review the chart and ECG himself before making the cath lab callback.
D-04 GAP: Unnecessary deference. Nurse has the full clinical picture. Redirecting physician to self-review adds avoidable delay.

Scene S1-B · SIMULUS PE-02 · Highest-Weight Node
Dr. Patel Orders Thrombolytics — But There's a Contraindication
SIMULUS PE-02D-04 CRITICALD-06 Safety
⚠ SIMULUS PE-02 · CONTRAINDICATED ORDER
Dr. Patel has ordered Alteplase (tPA) 100mg IV for STEMI. Chart shows: GI bleed hospitalization 3 weeks ago. Recent GI bleeding within 3 months = absolute contraindication to thrombolytics. Dr. Patel is now at the nurses' station, signing other orders. PCI remains available and preferred.
Clinical Note — Most Critical Node
Recent GI bleed (<3 months) is an ABSOLUTE contraindication to thrombolytic therapy. The correct action is PCI (already available). Giving tPA here = potentially fatal hemorrhage. This is the highest-weight pharmacology safety decision in the cardiac module.
Challenge 1 · D-04 · You see the GI bleed in the chart
The tPA bag is in your hand. The chart shows GI bleed 3 weeks ago. What do you do?
A
Hang the tPA — the physician has reviewed the patient and accepted the risk. Documenting your concern in the notes is sufficient; the prescribing decision belongs to the doctor.
D-04+D-06 CRITICAL GAP: Silent compliance. Seniority is not a contraindication override. Nurse administers = nurse accountable. CRITICAL.
B
Ask Dr. Patel: 'I want to confirm before hanging — is there anything specific about the GI bleed I need to document?' Then proceed if he reconfirms the order.
D-04 PARTIAL: Vague safety check. No contraindication named. Easily dismissed. Better than silent compliance but insufficient here.
C
"Dr. Patel — he had a GI bleed 3 weeks ago, a listed contraindication. Can you formally address this before I hang?" Pause infusion and document the exchange.
D-04+D-06 EXPERT: Specific contraindication named. Safer alternative offered. Drug not hung. Professional direct challenge.
D
Step out and ask the charge nurse to come review the order — high-risk infusions should have pharmacist sign-off before hanging, and this is not a bedside nursing decision to make alone.
D-04+D-06 GAP: Deflects responsibility. Physician may administer independently before charge nurse arrives. Safety gap unaddressed.
Thrombolytic Mechanism + Contraindication
How tPA Works
Alteplase (tPA) activates plasminogen → plasmin systemically, dissolving fibrin clots everywhere in the body — not just the coronary artery. This is why recent GI bleeding is an absolute contraindication: the healing ulcer will reopen and bleed catastrophically.
The Authority Trap
"I've been a cardiologist for 30 years" is not a contraindication override. The nurse holds the final administration check. Hanging a contraindicated drug, even when ordered by an expert, makes the nurse clinically and legally responsible for the outcome.
Two-Challenge Protocol
Research shows 85% of nurses capitulate on the second challenge when challenged by a senior authority figure. The nurses who hold firm cite protocol, not personal judgment. "I need a documented override" removes the interpersonal conflict from the safety act.
📚 Teaching Point
Evidence
⚠ PUSHBACK — SECOND CHALLENGE TEST
Dr. Patel: "I know the history. He's actively infarcting. The bleed risk is worth it. I've been a cardiologist for 20 years. Hang the drug — we're losing the window."
Challenge 2 — THE REAL TEST · Hold or Capitulate?
He dismissed you. The drug is still in your hands. He's watching. What do you do now?
A
Apologise and hang the tPA. He is the attending cardiologist of record and the GI bleed was three weeks ago — the physician-nurse relationship means following his direct clinical judgment.
D-04 CRITICAL GAP: Capitulated. Charted concern without refusal = same harm outcome. Seniority is not a contraindication override. CRITICAL flag.
B
Set the tPA down without speaking further, step out, and call the charge nurse. The situation has broken down — removing yourself and escalating through hierarchy is the appropriate response.
D-04 GAP: Conflict avoidance. No explicit hold stated. Dr. Patel may administer independently. Safety gap left open.
C
"Dr. Patel, I need your documented review of the contraindication before I hang this. Can you add a note, or I'll need to escalate to the on-call attending." Document everything.
D-04 + D-03 EXPERT: Holds firm. Protocol-grounded. Concrete escalation path offered. De-personalised. Does not capitulate. Top differentiator.
D
Tell Dr. Patel you are calling the on-call attending for a second opinion on the contraindication. This is a complex case and the final word should not rest on one clinical voice alone.
D-04 ADEQUATE: Correct escalation. No explicit "do not administer" stated in the room. Gap remains until attending callback. One step needed.

Mr. Osei's Family — "Do Everything"
D-02 CommunicationD-03 EthicsD-09 Cultural
Clinical Ethics — Advance Directive & Family Dynamics
Legal Reality
A DNR signed by a capacitated adult is a legally binding advance directive. Family members cannot revoke it after the patient loses capacity — they may only reflect what they believe the patient would want. The DNR stands.
Cultural Dimension
In Ghanaian (Akan) culture, family decision-making is often communal — the individual's advance directive may conflict with family consensus norms. The expert nurse honours both: the legal document AND the family's grief, without false promises.
Language Access
Using a family member to translate emotionally laden end-of-life discussions is a language access failure. The translator filters, interprets, and protects. A qualified Twi interpreter is required — even at 10pm.

S1-C-01 · Family Response · D-02 + D-03 + D-09
It is 10pm. You are the nurse. Mrs. Osei is crying. What is your response?
A
Acknowledge the family's grief, explain the DNR reflects his current medical status and is clinically standard, and ask the daughter to translate for her mother — she appears to understand English.
D-03 GAP: "Go over everything" implies possible reversal. Morning meeting creates false hope. DNR is settled — that should be clear tonight.
B
Sit with Mrs. Osei and, using the daughter as your interpreter since she is bilingual, compassionately walk through the goals of care and explain why the DNR is appropriate given his prognosis.
D-09 GAP: Daughter translating end-of-life decisions for her own parent = unreliable. Emotional filtering distorts clinical information in both directions.
C
Request a qualified Twi phone interpreter before saying anything clinical. No clinical content until the interpreter is live. Acknowledge grief, then verify the DNR reflects her husband's own stated wishes.
D-02+D-03+D-09 EXPERT: Interpreter first. Grief before procedure. DNR upheld without false hope. Palliative path offered. Complete.
D
Call a qualified Twi interpreter and wait until they are live before speaking. Acknowledge grief first, then confirm the DNR aligns with her husband's documented preferences before any further discussion.
D-02+D-09 ADEQUATE: Interpreter used, compassionate. Physician referral implies uncertainty about the DNR that does not exist. Creates wait without resolution.

ATRIAL FIBRILLATION — Cardioembolic Stroke Source
Brain — Left MCA Territory Stroke
The Penumbra — Why Minutes Matter
The ischemic penumbra (orange zone) surrounds the dead core — these neurons are stunned but alive, receiving marginal collateral flow. tPA or thrombectomy can save this tissue. Every 30 minutes without reperfusion converts penumbra to infarct core permanently.
FAST Signs Explained
Left MCA stroke produces right-sided deficits (brain contralateral to body) + Broca/Wernicke aphasia (dominant hemisphere). Right facial droop + right arm drift + jargon speech = classic MCA syndrome. NIHSS 14 = severe — Large Vessel Occlusion pattern.
BP 186/104 — Do NOT Treat
In acute stroke, autoregulation is lost. The brain needs permissive hypertension to push blood through collaterals into the penumbra. AHA guideline: do not lower BP until ≥185/110 before tPA, or ≥220/120 without tPA. Treating 186/104 worsens ischemia.

35 minutes to tPA window. CT not yet done. Stroke team not yet called. What are your first actions?
COGNITA: Stroke team activation time · CT prioritisation · BP management knowledge
A
Give labetalol 10mg IV to bring BP below 180 before any other interventions — treating uncontrolled hypertension is essential to prevent haemorrhagic conversion during imaging.
D-06 + D-05 GAP: BP 186/104 is below treatment threshold. Lowering it now reduces penumbral perfusion. Delays window. Causes harm.
B
Activate stroke alert. Stat CT head, 2× IV access, NIHSS, fingerstick, 12-lead. Do NOT lower BP — permissive hypertension is required. Call neurology immediately.
D-05 + D-07 EXPERT: Full parallel activation. BP correctly deferred. Stroke bundle complete. Time-optimal.
C
Call stroke neurology immediately with the clinical picture and wait at bedside for verbal orders — the diagnosis needs confirmation before starting any irreversible interventions.
D-07 ADEQUATE: Correct escalation, sequential execution. 6–8 min lost waiting for instructions that nurse can initiate per protocol.
D
Recheck blood glucose — a level of 148 could explain the confusion and focal signs. Treat potential metabolic causes before committing to a stroke workup and activating the alert.
D-08 GAP: Glucose 148 is hyperglycaemia, not hypoglycaemia. Focal deficits with NIHSS 14 are not a glucose effect. Stroke alert delay is unjustified.

CT: No hemorrhage. NIHSS now 16 (worsening). BP 188/106. 68 minutes since symptom onset — 22 minutes left in tPA window. Neurology resident Dr. Kim is present but hesitant. What do you prioritise now?
A
Treat the BP first — it is now 188/106, approaching the tPA eligibility threshold. Get it controlled before pushing for clearance, then reassess tPA candidacy with updated parameters.
D-06 GAP: 188/106 is still below the ≥185/110 tPA treatment threshold. Treating now delays administration, consumes window.
B
SBAR to Dr. Kim: 22 min left, NIHSS worsening to 16, CT clear, BP controlled. Window is closing — I need a yes, a no, or a formal refusal documented now.
D-04 + D-07 EXPERT: Consent framework delivered. Clinical urgency quantified. Physician empowered. Paralysis broken.
C
Call the stroke attending directly over Dr. Kim, reporting the NIHSS trajectory and the timeline pressure. If Dr. Kim has reservations, the attending should be the one to clear or decline tPA.
D-07 ADEQUATE: Correct escalation. Adds ~5 min communication loop. Nurse could also resolve Dr. Kim's paralysis directly and simultaneously.
D
Continue waiting for Dr. Kim's decision — he is the responsible physician and tPA is an irreversible intervention. Your role is to provide information and advocate, not to override clinical judgment.

The nurse who provides this information — "Situation: 12 minutes, NIHSS worsening; Background: Mr. Reyes is SDM and present; Assessment: SDM consent is legally valid here; Recommendation: he consents, we give tPA now" — breaks the paralysis and saves the patient. That is nursing advocacy at its highest form.

Clinical Teaching Point — Emergent Consent
In a time-critical emergency where a patient lacks capacity and treatment is clearly in their best interest, implied consent (emergency exception) applies. A competent adult spouse/next-of-kin can consent. The nurse's role is to advocate for the patient — including clearly informing the physician of the legal and ethical framework when they are hesitating.

Dr. Kim is hesitating. 12 minutes left. What do you do?
COGNITA: Does nurse articulate consent framework? Does nurse escalate past Dr. Kim? Advocate role.
A
Tell Dr. Kim you understand his caution and will keep paging the stroke attending. Return to the patient, recheck vitals every 5 minutes, and ensure documentation is current.
D-04 GAP: Passive. Each page attempt takes 2–3 minutes. 12 minutes is not enough for 4 attempts. Advocacy duty unmet.
B
SBAR to Dr. Kim: '12 min left, NIHSS 16 and worsening, CT clear, husband at bedside as SDM. Every minute costs neurons — I need a yes, a no, or I escalate to the stroke attending now.'
D-04 + D-07 EXPERT: Full SBAR with consent framework. Simultaneous escalation. Paralysis broken. Complete advocacy.
C
Go to Mr. Reyes directly and explain that his wife needs a clot-dissolving drug, walking him through the risks and benefits so he can give informed consent on her behalf.
D-02 GAP: Obtaining consent without physician involvement is outside nursing scope. Mr. Reyes needs clinical framing from Dr. Kim, not a form from the nurse.
D
Call the stroke attending directly, report Dr. Kim's hesitation and the narrowing window, and request a bedside review — this decision cannot be resolved over the phone in the time remaining.
D-07 ADEQUATE: Correct escalation. Adds communication loop. Misses opportunity to also give Dr. Kim the consent framework directly.

Mrs. Reyes' anticoagulation regime (apixaban for AF-related stroke prevention) is complex: dose timing, bleeding precautions, INR independence. Getting this wrong means a second stroke.
S2-C-01 · Discharge Teaching · D-09 + D-11
How do you conduct discharge teaching for anticoagulation, stroke signs, and medication adherence — with no common language and bed pressure?
A
Use Google Translate on your phone — it is fast, generally accurate for routine discharge content, and she appears to understand most of what you say based on her responses.
D-09 CRITICAL GAP: App-based translation fails for clinical discharge. "Translation assistance" obscures the gap. Anticoagulation errors → readmission in days.
B
Use Google Translate for the general overview and routine activity instructions, then request a formal interpreter only for medication management and return precautions.
D-09 ADEQUATE: Better than app-only. But "return precautions" and stroke signs are equally critical. All discharge content requires qualified interpretation.
C
Request a qualified Spanish phone interpreter. Use teach-back for every instruction — ask her to repeat each step back. Document interpreter name. Do not use family as interpreters.
D-09 + D-11 EXPERT: Qualified interpreter, full teach-back, explicit advocacy against shortcut. Readmission risk addressed.
D
Ask the couple's adult daughter to interpret the discharge instructions — she speaks both languages and clearly understands the medical context, making her more effective than a phone service.

Sepsis Cascade — Organ Dysfunction
Sepsis — The Host Response
Sepsis is not infection — it's the host's dysregulated immune response to infection that causes organ damage. Bacteria from the wound enter the bloodstream → massive cytokine release → vasodilation + endothelial damage → MAP falls → organs starve of oxygen → multi-organ failure.
SOFA Score — What It Measures
SOFA scores 6 organ systems: Respiratory (P/F ratio), Coagulation (platelets), Liver (bilirubin), Cardiovascular (MAP/vasopressors), CNS (GCS), Renal (creatinine/UO). A score ≥2 from baseline in a patient with suspected infection = sepsis.
Lactate 3.1 — What It Means
Lactate >2 mmol/L = anaerobic metabolism → tissues not getting enough oxygen despite a beating heart. Lactate >4 = septic shock criterion. Every hour untreated, lactate rises and mortality climbs. The 1-hour bundle was designed around this biology.

It is 0340. The attending is not physically in the unit. What is your immediate response?
COGNITA: Does nurse calculate SOFA or wait? Does nurse initiate 1-hour bundle without explicit order?
A
Increase monitoring frequency to every 30 minutes and document the trend carefully. Flag this case at handover — these changes may represent normal post-operative variation before escalating.
D-05 CRITICAL GAP: Surveillance escalation is not treatment escalation. SOFA 5 + Lactate 3.1 at 0340 requires immediate intervention, not a note for rounds.
B
Activate sepsis alert + rapid response. Draw blood cultures × 2 before antibiotics. Start broad-spectrum ABX and 30mL/kg IVF bolus now. Reassess lactate at 1 hour.
D-05 + D-07 EXPERT: Sepsis bundle initiated. Blood cultures before abx. Fluid and SBAR in parallel. Protocol-authorised independent action.
C
Start broad-spectrum antibiotics immediately — infection is obvious and every minute matters. Blood cultures can follow the first dose; getting treatment in is the clear priority here.
D-06 GAP: Antibiotics before cultures ruins diagnostic yield. The sepsis bundle sequence is cultures first, then antibiotics. Sequence error.
D
Page on-call physician with a full SBAR including the trend data. Draw blood cultures while waiting for the callback and ask about initiating the sepsis bundle before antibiotics.

The Delayed Antibiotic Problem
SIMULUS PE-06D-01D-07D-04
⚠ SIMULUS PE-06 · SEPSIS BUNDLE INCOMPLETE · 47 MIN
Pharmacist: "We should wait for culture sensitivities before choosing antibiotics — we don't want to over-treat." Junior resident: not responding to pages. MAP dropping to 56. Antibiotics are the single most time-critical intervention in sepsis — every hour of delay = 7% mortality increase. Broad-spectrum empiric ABX is the standard of care before sensitivities return (48–72 hrs).
Clinical Teaching — Sepsis ABX Timing
Sensitivities take 48–72 hours. In sepsis with MAP <65 despite fluid, empiric broad-spectrum antibiotics are mandatory and time-critical. Waiting for sensitivities before first dose is a clinical error. The nurse's role includes identifying and escalating dangerous delays in time-critical interventions.
S3-B-01 · Advocate for ABX · D-01 + D-04 + D-07
47 minutes in. MAP 56. No antibiotics. Pharmacist hesitating. Resident not responding. What do you do?
A
Accept the pharmacist's reasoning — they hold specialist antimicrobial stewardship expertise. Wait for sensitivity results and document the exchange, noting the clinical rationale for the delay.
D-04 GAP: Pharmacist guidance is reasonable-sounding but clinically wrong for sepsis. Passive acceptance. MAP falling. Advocacy unmet.
B
Call a rapid response immediately — the patient is deteriorating and the team dynamic has broken down completely. Rapid response will get senior clinical eyes at the bedside right now.
D-07 GAP: Disproportionate escalation. Rapid response for pharmacy disagreement misuses a critical resource. Attending escalation is the correct path here.
C
Bypass the pharmacist entirely and call the attending on-call directly. If the attending authorises the antibiotic over the pharmacist's objection, proceed and document the chain of authority.
D-07 ADEQUATE: Correct escalation, resolves this case. Pharmacist issue unaddressed for future patients. Single-channel advocacy.
D
"SSC guidelines require empiric ABX before sensitivities — his lactate is 4.2 and BP is falling. That IS your authority. I need piperacillin now, or I escalate to the attending."
D-04 + D-07 EXPERT: Guideline-cited pharmacist challenge + attending escalation simultaneously. Clinical urgency quantified. Both channels used. Complete advocacy.

Septic Shock — Vasopressor Mechanism
Septic Shock Definition
Septic shock = Sepsis + vasopressor-dependent hypotension (MAP <65 despite adequate fluid resuscitation) + lactate >2 mmol/L. This patient has lactate 4.8 and is on norepinephrine — meeting all criteria. ICU admission is mandatory.
Dual-Track Communication
90 seconds is enough for: "Your father is very sick. We've identified the infection. We're moving him to the ICU right now where he gets closer monitoring. Someone will meet you there." That's truthful, specific, forward-oriented — and it doesn't stop the ICU transfer.
SBAR for ICU Transfer
S: Mr. Al-Fayed, 72M, septic shock, transferring urgently. B: Post-op Day 3 colon resection, surgical site source, SOFA 5, Lactate 4.8. A: MAP 49 on Norepi 0.1 mcg/kg/min, anuric. R: ICU bed, arterial line monitoring, nephrology consult.

ICU Transfer Decision — And the Family
SIMULUS PE-07D-05ICUD-02
⚠ SIMULUS PE-07 · SEPTIC SHOCK · ICU TRANSFER REQUIRED
MAP 49 despite 30mL/kg fluids and norepinephrine 0.1 mcg/kg/min. Lactate 4.8 (worsening). Anuric. Septic Shock criteria met: vasopressor-dependent hypotension + lactate ≥4. Mr. Al-Fayed's son is at bedside: "Please — is my father dying? No one has told us anything."
S3-C-01 · Simultaneous Crisis Management · D-05 + D-02
MAP 49. Son desperate for information. ICU team en route. How do you manage both the clinical escalation AND the family in the same moment?
A
Focus completely on the ICU transfer — the son can be updated once Mr. Al-Fayed is safely admitted and stable enough for a proper conversation.
D-02 GAP: Silent transfer in crisis produces family conflict that obstructs admission. 90 seconds of communication prevents 10 minutes of disruption.
B
Spend three minutes with the son: "Your father is critically ill from an infection. We are moving him right now to the ICU for higher-level monitoring and treatment. I will make sure the ICU team calls you in the next 30 minutes." Then transfer without formal SBAR handoff.
D-02 EXPERT + D-05 PARTIAL: Excellent family communication. SBAR omitted — ICU team receives incomplete clinical picture. One strong, one incomplete.
C
90 seconds to son: "Your father has a serious infection — we've found it and we're treating it. We're moving him to the ICU now. Someone will meet you there." Continue ICU prep simultaneously. Deliver complete SBAR to ICU team en route.
D-05 + D-02 EXPERT: Parallel tracks. 90-second honest family communication + full SBAR. Neither compromised. Dual-domain expert.
D
Direct the son to the family waiting room and tell him a nurse will come to speak with him once the transfer is complete — it is important not to have family present during an active transfer.
D-02 + D-05 GAP: Isolating a distressed family member without acknowledgment or timeline creates conflict. No therapeutic communication. No clinical handoff improvement.

Consequence · Post-transfer — Charge nurse debrief
Mr. Al-Fayed is now in the ICU. You return to the ward at 0620. Charge nurse: "That was a hard night. You caught that sepsis — the on-call said if it had waited until 0600 it would have been too late. How are you doing?"
A
"It's part of the job — we deal with difficult situations all the time and you develop a skin for it. I'm completely fine. Let's just focus on getting the handover notes done properly."
D-12 SUPPRESSION: Normalisation response. High-risk pattern for moral injury accumulation over time. Deflects acknowledgment.
B
"That was hard — glad we caught it when we did. I'll flag the antibiotic delay to the clinical educator tomorrow." Healthy acknowledgement with systems follow-through.
D-12 INTEGRATION: Experience named, acknowledgment accepted, support plan identified. Healthy professional processing. RESONANCE strength pattern.
C
"It was a tough shift — one of those nights where everything goes sideways at once. I'm tired but okay. Thanks for asking. Let's get the notes sorted before handover."
D-12 ADEQUATE: Acknowledgment accepted, no suppression. No forward step identified. Better than suppression, incomplete processing.
D
"We need to look at why the antibiotics were delayed — that pharmacy situation concerns me most. Let's write it up as an incident report right now before the details get fuzzy."
D-12 GAP: Redirecting to systems improvement deflects the personal wellbeing check. Important issue, wrong moment. Suppression variant.

What do you do right now?
A
Document the trends and hand over to the day team with a priority flag — the shift ends in 45 minutes and day staff will have full context and more time to investigate properly.
GAP Retest: Delayed escalation pattern.
B
Activate sepsis alert. Draw blood cultures × 2 before antibiotics. Start broad-spectrum ABX and 30mL/kg IVF bolus. Reassess lactate at 1 hour.
EXPERT Retest: Correct pattern confirmed.
C
Start broad-spectrum antibiotics immediately and then draw cultures — with this clinical picture there is no time to wait for the correct sequence before getting treatment in.
GAP Retest: ABX before cultures.
D
Call the on-call physician with a full SBAR, draw blood cultures while waiting for the callback, but hold antibiotics until the physician confirms the diagnosis and places the order.
ADEQUATE Retest: Passive bundle start.
