____shock is a sudden reaction of the nervous system that produces temporary vascular dilation and fainting
Neurogenic shock
Cardiongenic shock

Vascular shock
Inadequate circulation of blood throughout the body is called
shock
perfusion
hypoxia
hypotension
What are the three components of the "perfusion triangle"
Arteries, veins, capillaries
Plasma, red blood cells, platelets
Heart, brain, lungs
Heart, blood vessels, blood
You suspect you patient is in shock. You note the pt's skin is pale. This is likely due to
an increase in heart rate
peripheral vasodilation
peripheral vasoconstriction
hypothermia
Shock due to severe infection is called
Hypovolemic shock
Anaphalatic shock
neurogenic shock
Septic Shock
Your patinet has a decreased cardiac output and poot myocardial contractility. This will likely lead to
hypovolemic shock
cardiogenic shock
neurogenic shocl
septic shock
Foods, medicaion and insects are common causes of
septic shock
anaphalactic shock
neurogenic shock
psychogenic shock
Your patient is in shock, but the body's defense mechanisms are currently able to maintain adequate circulation. This is called
compendated shock
decompensated shock
late shock
irreversible shock
As you approach a patient lying at the side of the roadway, you observe severe bleeding from the leg. What should your first action be
Check for pulse
Control the bleed
Open the airway
Administer O2
When should nonlifesaving interventions be performed for your multisystem trauma patient?
En route to the hospital
prior to transport
During the primary assessment
Immediatly after the injuries are discovered
To protect vital organs, the body compensates by directing blood flow away from organs that are more tolerant of low flow, such as
the skin
the heart
the brain
the lungs
Life threating allergic reaction can occir in response to almost any substance that a patient may encounter
True
False
Bleeding is the most common cause of cardiogenic shock
true
false
Shock occurs when oxygen and nutrients cannot get into the body's cells
true
false
A person in shock, left untreated, will survive
true
false
Compensated shock is related to thelast stages of shock
true
false
An injection of epinephrine is the only really effective treatment for anphylactic shock
true
false
Septic shock occurs a reaction to a severe infection
true
false
Metabolism is the cardiovascular system's circulation of blood and oxygen to all cells in different tissues and organs of the body.
true
false
Shock occurs only with massive bloos loss from the family
true
false
Decompensated shock occurs when the systolic blood pressure falls below 120 mmHg.
true
false
Pulmonary edema an impaired ventilation occur duing
septic shock
neurogenic shock
cardiogenic shock
anaphylactic shock
Which of the following injuries would MOST likely cause obstructive shock?
Liver laceration
Cardiac tamponade
Simple pneumothorax
Spinal cord injury
Distributive shock occurs wehn
an injury causes restiction of the heart muscle and impairs it pumping function
severe bleeding causes tachycarida in order to distribute bkood tot he organs faster
temporary but severe vasodilation causes a decrease in blood supply to the brain.
widespread dilation of the blood vessels causes blood to pool in the vascular beds.
In an acute injury setting, neurogenic shock is commonly accompanied by
hypovolemia
tachycardia
diaphoresis
hypothermia
Hypovolemic shock cause by severe burns is the result of a loss of
plasma
platelets
whole blood
red blood cells
When asssessing a patient with signs and symptoms of shock, it is importnat to remember that
the patient's respirations are deep suring the early stages of shock
blood pressue may be the last measurable factor to change in shock
multiple fractures are the mose common cause of hypovolemic shock
irreversible shock often responds to a prompt blood transfusion
When treating an 80 y/o patient who is in shock, it is important to remember that
Compensation from the respiratory system usally manifest with increased tidal volume
the older patient's central nervous system usually reacts more briskly to compensation for shock
medications older patients take for hypertension often cause an usually fast heart rate
changes in gastric mobility may delay gastric emptying, which increases the risk for vomiting.
a 25 y/0 unrestrained female struck a steering wheel with her chest when her car hit a tree at a high rate of speed. she has sxs of shock, which you suspect are the result of intrathoracic bleeding. Which interventions will provide greatest chance for survival?
high flow O2
full immobilization of her spine
intravenous fluid administration
rapid transport to a trauma center
Whoch of the following is the ONLY action that can prevent eventual death from a tension pneumothorax?
early adminstration of high flow O2
rapid administration of IV fluids
Decompression of the injured side of the chest
Postive-pressure ventilation with a BVM
a 20 y/o male has a large laceration to his wrist. He is holding a blood-soaked towel over the wounds, but it continues to bleed rapidly. You should
apply pressure to brachial artery
apply a tourniquet proximal to the wrist
administer high flow supplemental O21
wrap the towel with pressure bandages.
