Why is it important to understand biomechanics as it relates to types of energy forces and mechanism of
injury (MOI)? - ANSWER✔ To understand and anticipate potential injuries.
What are common MOIs that result in trauma? - ANSWER✔ Blunt and Penetrating
What is the most common mechanism of blunt trauma seen at your facility? Penetrating trauma? -
ANSWER✔ Blunt- Falls
Penetrating- GSW
Why is it important to use a systematic approach to the initial assessment of a trauma patient? -
ANSWER✔ To maximize outcomes and reduce the risk of undiscovered injuries.
What is included in the preparation for a trauma patient? - ANSWER✔ - Activate the Trauma Team
and assign roles
- Prepare the room/equipment
- Don PPE
- Consider safety threats
- Decontamination
What information is obtained during the general impression? - ANSWER✔ - Uncontrolled
hemorrhage
- Unresponsiveness/Apnea
- Need to reprioritize C-ABC
What does the A-J mnemonic stand for? - ANSWER✔ A** Alertness (A1) and Airway (A2)
B** Breathing and Ventilation
C** Circulation and Control of Hemorrhage
,D** Disability (Neurologic Status
E** Exposure (E1) and Environmental Control (E2)
F- Full Set of Vital Signs (F1) and Family Presence (F2)
G- Get Adjuncts (G1) and Give Comfort (G2) [L-P]
H- History (H1) and Head-to-Toe (H2)
I- Inspect Posterior Surfaces
J- Just keep reevaluating (VIPP)
Why is alertness included with the airway assessment? - ANSWER✔ To evaluate the Pts ability to
protect their airway
AVPU
- Alert and Orientated
- Verbal (responds to)
- Pain (responds to)
- Unresponsive
When an intervention is taken during the primary survey, what must the nurse do after the
intervention? - ANSWER✔ Reassess effectiveness and move on to the next component
What are the components of the secondary survey? - ANSWER✔ H- History and Head to Toe
I- Inspect Posterior
J- Just Keep reevaluating (VIPP)
What laboratory tests are commonly utilized for trauma patients? - ANSWER✔ VBG/ABG
Lactic
CMP/CBC
Type Screen
Clotting Factors
UA
, What should the nurse reevaluate while the patient is in their care? - ANSWER✔ VIPP
V- Vital
I- Injuries/Interventions
P- Primary Survey
P- Pain
What are the differences between ventilation, diffusion, and perfusion? - ANSWER✔ Ventilation-
movement of air
Diffusion- movement of gases from high concentration to lower concentration, alveolar-capillary
membrane exchange
What are possible causes of airway obstruction in the trauma patient? What interventions address these
causes of airway obstruction? - ANSWER✔ Tongue
Blood, vomit, secretions
Altered LOC
Trauma
Obesity
Interventions- suctions, jaw thrust, insert airway
What is the difference between an airway adjunct and a definitive airway? - ANSWER✔ Adjunct
airway- upper airway management
- nasopharyngeal
- oropharyngeal (unresponsive/no gag reflex)
- extraglottic (Supra or Retro "king tube")
Definitive airway- placed within the trachea below the vocal cords
What is the difference between normoxia and hyperoxia? Why does it matter? - ANSWER✔
Normoxia- Pa02 60-120 mmHg
Hyperoxia- Pa02 >120 mmHg
