glasgow-coma-scale 15-point neurological scoring for eye, verbal, and motor responses
sample-opqrst History-taking frameworks: symptoms, allergies, meds, pertinent history, last oral intake, events; onset, provocation, quality, radiation, severity, time
dcap-btls Physical exam mnemonic: deformity, contusions, abrasions, punctures, burns, tenderness, lacerations, swelling
vital-signs Baseline assessment: BP, pulse rate/quality, respirations, skin, pupils, SpO2
pulse-oximetry SpO2 measurement, normal ranges, limitations, and when the number lies
six-rights Medication administration checklist: patient, drug, dose, route, time, documentation
shock-physiology Cellular hypoperfusion, compensated vs. decompensated, shock types and progression
kinematics-of-trauma Energy transfer, blunt vs. penetrating mechanisms, predictable injury patterns
rule-of-nines Body surface area estimation for burns: head 9%, each arm 9%, each leg 18%
cincinnati-stroke-scale Three-finding stroke screen: facial droop, arm drift, speech — any positive = stroke
apgar-score Neonatal assessment at 1 and 5 minutes: appearance, pulse, grimace, activity, respirations
start-triage Mass casualty triage: 30-2-can-do sorting into immediate, delayed, minor, deceased
load-and-go-vs-stay-and-play Is the thing killing this patient fixable in the field? 10-minute scene time target; conditions that mandate immediate transport
