When I took the TNCC course for the first time I took it with about 20 other RNS, some of which had been ER RN for over 20 years. I passed the first time around and many of them did not. HOWEVER< where I took it they were allowed to turn around and take the written exam again and try to pass if they failed that part. As for the practical part, it is really a head to toe exam with the examiner providing info about type of injury, etc, what the lungs sounds are, heart sounds are, and you taking it with what they tell you and performing the appropriate interventions, etc. One thing we all had to do was remove a helmet from a motorcycle head injury patient. HARD< when you aren't cutting it off.
When you read the test questions, they are alot like intense NCLEX questions. READ AND TAKE IN ALL the info. age, preexisting conditions, labs, injuries, prior intervetions before arrival, etc. and REMEMBER do NOT PANIC, justfocus on appropriate interventions for what is wrong.remember positioning for conditions and symptoms of injury.Our two day course was first day of instruction, second day of testing. Divided into practicum groups, after written tests.It is really just accumulating information, and providing interventions.
