Define the characteristics of neurogenic shock - ANSDistributive 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 - ANSTransient 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 - ANSWith longform
fractures. Tachycardia, Thrombocytopenia, and petechiae rash.
Describe the characteristics of cardiogenic shock - ANSCardiogenic 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. - ANSDistributive 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 - ANSHypovolemia 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 - ANSObstructive 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 - ANSCentral 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 - ANSMeasure 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. - ANSThe first impact occurs
