Comprehensive Study Guide for TNCC 9th Edition
This guide provides a structured review of the core concepts taught in the
Trauma Nursing Core Course (TNCC) 9th Edition to help you prepare for
the exam and practical scenarios.
1. TNCC Overview
The TNCC emphasizes teamwork, systematic trauma assessment, and
evidence-based interventions to improve patient outcomes. Key principles
include:
Prioritizing life-threatening conditions.
Using the ABCDE approach for initial assessment.
Collaborating effectively in trauma teams.
2. Primary Survey (ABCDE Approach)
The primary survey identifies and treats life-threatening injuries in a
systematic manner:
A: Airway with Cervical Spine Protection
Assess for airway obstruction (stridor, hoarseness, gurgling,
inability to speak).
Secure the airway using appropriate techniques (jaw thrust,
intubation).
Always stabilize the cervical spine in suspected spinal injuries.
B: Breathing and Ventilation
Assess chest rise, respiratory rate, oxygen saturation, and
auscultate lung sounds.
Recognize and manage:
o Tension pneumothorax: Perform needle decompression.
o Open pneumothorax: Apply a three-sided occlusive
dressing.
o Flail chest: Support with positive pressure ventilation if
necessary.
C: Circulation with Hemorrhage Control
Check central pulses, capillary refill, and skin color.
Control visible bleeding with direct pressure or tourniquets.
