TNCC 8th Edition
According to newtons law which of these two force is greater: size or force? –
CORRECT ANSWER: Neither. For each force there is an equal and opposite reaction.
Define Cushing's triad –
CORRECT ANSWER: Bradycardia, progressive hypertension (widening pulse pressure), and
decreased respiratory effort
Define the characteristics of neurogenic shock –
CORRECT ANSWER: Distributive shock with a T6 or higher injury results and vasodilation,
bradycardia, flushed warm dry skin. Risk for temperature instability. Nursing interventions
include maintaining warmth and spinal stabilization.
Define the characteristics of spinal shock –
CORRECT ANSWER: Transient loss of function can include loss of reflexes and muscle tone
below the level of industry with possible vascular response.
Describe one fat embolism syndrome is most likely to occur in its characteristics –
CORRECT ANSWER: With longform fractures. Tachycardia, Thrombocytopenia, and
petechiae rash.
Describe the characteristics of cardiogenic shock –
CORRECT ANSWER: Cardiogenic shock results from pump failure in the presence of adequate
intravascular volume. Lack of cardiac output and an organ perfusion occurs secondary to a
decrease in myocardial contractility and or valvular insufficiency. This can happen with blunt
cardiac trauma or an MI. Symptoms can include low blood pressure increase heart rate and
respiratory rate chest pain shortness of breath dysrhythmias increase troponin and pale cool
moist skin
Describe the characteristics of distributive shock. –
CORRECT ANSWER: Distributive shock occurs as a result of Mel distribution of an adequate
circulating blood volume with the loss of vascular tone or increased permeability. This can occur
with spinal cord injuries, sepsis, or anaphylaxis. Symptoms include low blood pressure heart rate
respiratory rate preload and afterload, spinal tenderness, difficulty breathing, warm pink and dry
skin with a cool core temperature.
Describe the characteristics of hypovolemic shock –
CORRECT ANSWER: Hypovolemia is caused by a decrease in the amount of circulating
volume usually caused by massive bleeding, but also can be from vomiting and diarrhea.
Characteristics include low blood pressure and preload, increase heart rate respiratory rate and
, afterload, with contractility unchanged. Signs include obvious bleeding, weak peripheral pulses,
pale cool and moist skin, distended abdomen, pelvic fracture, or bruise swollen and deformed
extremities especially long bones.
Describe the characteristics of obstructive shock –
CORRECT ANSWER: Obstructive shock is it mechanical problem that results from
hypoperfusion of the tissue due to an obstruction in either the vasculature or the heart resulting in
decreased cardiac output. Some causes include a tension pneumothorax, cardiac tamponade, or
venous air embolism on the right side of the heart during systole in the pulmonary artery.Signs
include anxiety, muffled heart sounds, JVD, hypertension, chest pain, difficulty breathing, or
pulses paradoxes.
Describe the four types of spinal cord injury –
CORRECT ANSWER: Central cord injury results in greater weakness distally, anterior injury
includes motor loss or weakness below the cord level of injury yet sensory is intact, Brown-
Sequard (hemicord) is weak on one side with sensory deficit on opposite side, posterior cord
syndrome although rare is when the patient is unable to use sense vibration in proprioception
Describe the measurement of an NPA –
CORRECT ANSWER: Measure from the tip of the patient's nose to the tip of the patients
earlobe.
Differentiate between the three impacts of motor vehicle impact sequence. –
CORRECT ANSWER: The first impact occurs when the vehicle collided with another object.
The second impact occurs after the initial impact when the occupant continues to move in the
original direction of travel until they collide with the interior of the vehicle or meet resistance.
The third impact occurs when internal structures collide within the body cavity.
Measurement of an OPA –
CORRECT ANSWER: Place the proximal end or flange of the airway adjunct at the corner of
the mouth to the tip of the mandibular angle.
Name the three ways to confirm ETT placement –
CORRECT ANSWER: Placement of a CO2 monitoring device, Assessing for equal chest rise
and fall, and listening at the epigastrium and four lung fields for equal breath sounds.
True or false: NPAs and OPAs are definitive airways. –
CORRECT ANSWER: False. When placing one of these? One should consider the potential
need for a definitive airway.
What are contributing factors to injuries related to blunt traumas? –
