✔✔Decompensated/Progressive shock
Obtunded/comatose, profound hypotension, bradycardia, dysrhythmias, slow shallow
respirations, petechiae/purpura are signs of what? -✔✔Irreversible shock
Benefits of the trauma nursing process -✔✔Systematic approach to the evaluation of
each trauma patient. Identifies life-threatening conditions, determines priorities of care.
Efficient production of ATP, which maintains cellular metabolic function, is seen with
what type of metabolism? -✔✔Aerobic metabolism
Inefficient production of ATP, byproduct is lactic acid, leads to metabolic acidosis,

metabolism
The cellular process in which oxygen is used to metabolize glucose. Energy is produced
in an efficient manner with minimal waste products. -✔✔Aerobic metabolism
The cellular process in which glucose is metabolized into energy without oxygen.
