TNCC Test Prep: Key Notes & Essential Points
The ABCDEFGHI Mnemonic
A = Airway with cervical spine protection
B = Breathing and ventilation
C = Circulation and hemorrhage control
D = Disability (neurologic status)
E = Exposure (undress patient, prevent hypothermia)
F = Full set of vital signs
G = Get resuscitation adjuncts (labs, monitors, tubes)
H = History (AMPLE)
I = Inspect posterior surfaces (logroll with spinal precautions)
Primary Survey - Key Points
Airway is the FIRST priority
Airway compromise causes death within minutes
Uncontrolled hemorrhage is the most common preventable cause of death
Tension pneumothorax requires immediate needle decompression
Beck's triad: muffled heart sounds, hypotension, JVD = cardiac tamponade
Shock Classes
Class I: <15% blood loss, HR <100, normal BP
Class II: 15-30% blood loss, HR >100, normal BP
Class III: 30-40% blood loss, HR >120, hypotension
Class IV: >40% blood loss, HR >140, severe hypotension
