What alteration to ABC can exist, what is that alteration and when is it identified? -
Answer-<C>ABC, <C> signifies catastrophic haemorrhage, identified during across the
room assessment.
What is MARCH - Answer-M Massive Haemorrhage
A Airway
R Respiration- decompress suspected tension pneumo, seal open chest wounds
C Circulation
H Head injury/ Hypothermia
What is the A in AVPU? - Answer-Alert
What is the V in AVPU and what intervention may it indicate? - Answer-Responds to
verbal stimuli, an airway adjunct may be needed to keep the tongue from obstructing
the airway.
What is the P in AVPU and what intervention may it indicate? - Answer-Responds to
pain, patient may not be able to maintain his or her airway and airway adjunct may be
needed while further assessment is made to determine intubation necessity.
What is the U in AVPU and what must occur if this is the case? - Answer-Unresponsive,
announce loudly and direct someone to check for pulses while assessing if the cause of
the problem is the airway.
What do you inspect for in the airway? - Answer-Tongue obstruction, loose or missing
teeth, foreign objects, blood, vomit, secretions, edema or evidence of burn.
What is listened for with airway assessment? - Answer-Obstructive airway sounds such
as snoring, gurgling or stridor,
, What is palpated with airway assessment? - Answer-Occlusive maxillofacial bony
deformity.
How can you ascertain if the advanced airway is properly placed? - Answer-1) Rise and
fall of chest
2) Absence of gurgling on auscultation over epigastrium
3) Bilateral breath sounds
4) CO2 detection
What are 2 examples of airway adjuncts? - Answer-Nasopharyngeal airway and
Oropharyngeal airway
What are the 3 indications for a definitive airway? - Answer-1) Failure to maintain or
protect the airway
2) Failure to maintain oxygenation or ventilation
3) A specific anticipated clinical course
What is a definitive airway? - Answer-A tracheal tube securely placed in the trachea
with the cuff inflated.
How do you determine when to use a naso or oropharangyeal airway? - Answer-Naso if
they are conscious, oro if they have no gag reflex.
What GCS score necessitates a definitive airway? - Answer-8 or less
What is inspected during breathing assessment? - Answer-Spontaneous breaths,
symmetrical chest rise and fall, depth pattern and rate, signs of difficulty, skin color,
open pneumothoraces, JVD, singed nasal hairs.
JVD and tracheal deviation can be an indication of what? - Answer-Tension
pneumothorax
What and where do you auscultate during breathing assessment? - Answer-Presence,
quality, and equality at the 2nd intercostal space midclavicular line and the bases at the
5th intercostal space anterior axillary line.
What do you palpate for during the breathing assessment? - Answer-Bony structures
and possible rib fractures.
How quickly should you ventilate with a bag mask device? - Answer-10-12 breaths per
minute
Give 4 examples of life threatening pulmonary injuries. - Answer-1) Open pneumothorax
2) Tension pneumothorax
3) Flail chest
4) Hemothorax
