Four Patients, One Ambulance: Triage Under a Transport Constraint
You are the only clinician on duty in a four-room urgent care annex attached to a rural clinic. Between 14:00 and 14:20 four patients arrive. A: 62-year-old with crushing substernal chest pressure for 40 minutes, diaphoretic, BP 148/92, HR 104, SpO2 94% on room air, no documented aspirin allergy. B: 29-year-old with asthma, speaking full sentences, peak flow 70% of personal best after two albuterol nebulizers given in the waiting room, RR 26. C: 8-year-old with a visibly deformed forearm after a fall, warm hand, capillary refill under 2 seconds, pain 8/10. D: 45-year-old with an ankle sprain, walking comfortably, here mainly for work-release paperwork. The nearest emergency department is 35 minutes away by ambulance. One ambulance is available with an ETA of 12 to 20 minutes; a second unit is 50 minutes out.
1. Sequence the next 30 minutes for all four patients and state where each should end up. Justify the ordering.

Order by time-to-harm, not arrival time.
- A (first, simultaneous workup and transport): pressure plus diaphoresis plus tachycardia reads as possible acute coronary syndrome. ECG, monitoring, aspirin if no contraindication, IV access, and EMS transfer. Nothing else on this list kills within the hour in the same way.
- B (second, treated while awaiting the second unit): a peak flow at 70% after two nebs means she is failing initial therapy, not that she is fine because she is speaking sentences. Continuous nebulization, systemic corticosteroid, reassess in 15 to 20 minutes. She becomes the transport priority if she does not improve or worsens.
- C (urgent, not emergent): deformity with a warm hand, brisk capillary refill, and no neuro deficit means no limb-threatening vascular compromise right now. Analgesia and immobilization, then imaging by another route.
- D (deferrable): stable, ambulatory, no acute complaint. Paperwork is not a clinical priority and can be done later or rescheduled.
The judgement being tested is resisting arrival order, patient volume, and verbal pressure as sorting criteria. State the reassessment interval for B explicitly, because that is what converts a plan into a safe plan.
2. Patient D's employer calls and says D must be seen before 16:00, and D threatens to file a complaint about being 'skipped.' What do you say and do?
Read the worked answer
The complaint threat is not a clinical finding and does not change the order.
- Acknowledge, do not defend. Name the frustration, state the rule once: patients are seen in order of clinical urgency, not arrival or administrative need. Do not apologize for a triage decision that was correct.
- Offer real options: an estimate of when you can see D, the option to wait, or reschedule and complete the paperwork at that visit. Give the employer the same factual message, without discussing anyone else's care.
- Do not disclose the other patients' conditions as justification; 'another patient is sicker' invites argument. Say only that urgent cases are being handled.
- Document the request, the time, what was explained, and that clinical order was unchanged. If the pressure continues or becomes abusive, escalate to the supervisor and note it.
The trap is treating a complaint as a risk to be managed by reordering care. It is a communication problem with a documentation trail, not a triage criterion.
3. Patient B's SpO2 falls to 89% on room air while the single ambulance is loading Patient A. What changes, and what does not?
Read the worked answer
Two things change and one does not.
Changes:
- B is now a second time-critical patient. Escalate therapy immediately, place on oxygen, continuous nebs, reassess within minutes, and call for the second unit now rather than at the 50-minute mark.
- The decision about who takes the first ambulance becomes a comparison of who will deteriorate fastest, not who arrived first. If B remains hypoxic despite maximal on-site therapy, B may need the first unit while A, if pain-free, monitored, and hemodynamically stable, goes by the second or by another appropriate means.
Does not change:
- A's clinical urgency. Do not simply re-label A as 'stable' to free the ambulance; document the actual reassessment that supports any change.
- The obligation to keep both patients monitored while waiting.
The general principle: when a scarce resource can carry only one patient, the question is 'who cannot survive the delay.' Record the times you requested each unit, the vitals that drove each decision, and who was notified. If the outcome is later questioned, the reasoning trail is what demonstrates the decision was defensible rather than arbitrary.
