ABCs stand for
Airway: if the air way is compromised — this is always first when answering question
breathing: oxygen problem = immediate priority
Circulation
A - Airway
Ask :is th airway open
-Obstruction
choking
stridor(high pitch, hash or noisy sounds)
tongue blocking
vomiting secretion
if the air way is compromised — this is always first when answering question
B - Breathing
Ask: is the patient breathing well?
respiratory rate too high or too low
low SpO2
shortness of breath
use of accessory muscle
cyanosis
oxygen problem = immediate priority
C - Circulation
Ask: is the blood circulating adequately?
bleeding
hypotension
shock
chest pain
poor perfusion
if A is a problem,
ignore B and c
if B is the problem
ignore C
Example of ABCs
A patient has :
SpO2 88%
BP 150/90
Pain 7/10
Breathing (B) comes before pain and blood pressure
Easy memory trick
You will need air way to breathe, and you need breathing to circulate
when two answer choices Both sound correct and both contains priority words,
use fixed order of rules to break the tie and pick the best one
when two answer compete, select
the one that saves life first, fastest, and with least delay
in select all that apply question
choose answers that
Address airway, breathing, circulation
✔ Prevent immediate harm
✔ Use action verbs (apply, position, initiate
in select all that apply question, do not chose
Teaching
Documentation
Long-term prevention
Non-urgent comfort measures
when no ABCs are present look for safety and risk word like:
ASK: which answer prevents the patient from being harmed right now.)
fall risk
Seizure precautions
Aspiration risk
infection control
Bleeding precaution
restraint safety
( prevent harm beats comfort or teaching)
Acute vs chronic
ASK: which problem is new or unstable?
Acute / sudden/ new onset beats chronic/ expected
Maslow (physiological needs first)
physiological > safety > psychosocial
watch out for words like
pain
nutrition
elimination
sleep
fluid balance
Assess vs Implement
Assess first if you don’t know the problem
implement first if the problem is clear
teaching/ psychosocial (last) words
education
coping
emotional
