Failed chest decompression — DipIMC MCQ

Correct answer: B — Escalate to finger thoracostomy by an appropriately trained clinician

Explanation lettering: C = shown as A · A = shown as B · B = shown as C · E = shown as D · D = shown as E

A is correct: Persistent tension physiology after needle decompression suggests failure or blockage and needs definitive decompression within scope and governance. B is less suitable because it does not address the discriminator in the vignette; C is less suitable because a detailed survey is inappropriate before correcting an immediate threat; D is less suitable because it moves the patient before the decisive threat or destination issue is addressed; E is less suitable because pre-alert is needed when definitive teams must prepare. The most tempting alternative is therefore suboptimal because it either delays the time-critical pre-hospital intervention or sends the patient to the wrong level of care. The key DipIMC principle is focused cABCDE decision-making with early pre-alert, triage or retrieval escalation when the scene physiology demands it.
