TNCC CHAPTER 5 100% CORRECT QUESTIONS AND ANSWERS
ABG's provide values of Oxygen, CO2 and base excess, which are reflective of
endpoint measurements of what? - ANSWERS Cellular prefusion, Adequacy of
ventilation, and the success of resuscitation.
If ventilation is ineffective with oxygen via a nonrebreather mask, what should you do? -
ANSWERS Assist ventilation with bag-mask and oxygen at 15L/min at 10-12 breaths
per minute.
What should be done after IV access is obtained? - ANSWERS Obtain a blood sample
for type and crossmatch.

for complications related to the injury.
