D) Heart, blood vessels, blood
What are the three components of the “perfusion triangle”? A) Arteries, veins, capillaries B) Plasma, red blood cells, platelets C) Heart, brain, lungs D) Heart, blood vessels, blood

200

A) compensated shock
Your patient is in shock, but the body's defense mechanisms are currently able to maintain adequate circulation. This is called ___________. A) compensated shock B) decompensated shock C) late shock D) irreversible shock

200

B) Cardiac tamponade
Which of the following injuries would MOST likely cause obstructive shock? A) Liver laceration B) Cardiac tamponade C) Simple pneumothorax D) Spinal cord injury

200

B) blood pressure may be the last measurable factor to change in shock.
When assessing a patient with signs and symptoms of shock, it is important to remember that: A) the patient's respirations are deep during the early stages of shock. B) blood pressure may be the last measurable factor to change in shock. C) multiple fractures are the most common cause of hypovolemic shock. D) irreversible shock often responds well to a prompt blood transfusion.

200

C) Bacterial damage to the vessel wall, leaking blood vessels, and vasodilation
Which of the following MOST accurately describes septic shock? A) Bacterial infection of the nervous system with widespread vasodilation B) Widespread vasoconstriction and plasma loss due to a severe viral infection C) Bacterial damage to the vessel wall, leaking blood vessels, and vasodilation D) Viral infection of the blood vessels, vascular damage, and vasoconstriction

300

C) peripheral vasoconstriction
You suspect your patient is in shock. You note the patient's skin is pale. This is likely due to ___________. A) an increased heart rate B) peripheral vasodilation C) peripheral vasoconstriction D) hypothermia

300

B) Control the bleeding.
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? A) Check for a pulse. B) Control the bleeding. C) Open the airway. D) Administer oxygen.

300

D) widespread dilation of the blood vessels causes blood to pool in the vascular beds
. Distributive shock occurs when: A) an injury causes restriction of the heart muscle and impairs its pumping function. B) severe bleeding causes tachycardia in order to distribute blood to the organs faster. C) temporary but severe vasodilation causes a decrease in blood supply to the brain. D) widespread dilation of the blood vessels causes blood to pool in the vascular beds

300

D) changes in gastric motility may delay gastric emptying, which increases the risk for vomiting.
When treating an 80-year-old patient who is in shock, it is important to remember that: A) compensation from the respiratory system usually manifests with increased tidal volume. B) the older patient's central nervous system usually reacts more briskly to compensate for shock. C) medications older patients take for hypertension often cause an unusually fast heart rate. D) changes in gastric motility may delay gastric emptying, which increases the risk for vomiting.

300

A) failure of the nervous system causes widespread vasodilation.
Neurogenic shock occurs when: A) failure of the nervous system causes widespread vasodilation. B) the spinal cord is severed and causes massive hemorrhaging. C) there is too much blood to fill a smaller vascular container. D) massive vasoconstriction occurs distal to a spinal cord injury.

400

A) septic shock
Shock due to severe infection is called ________. A) septic shock B) neurogenic shock C) anaphylactic shock D) hypovolemic shock

400

A) En route to the hospital
When should nonlifesaving interventions be performed for your multisystem trauma patient? A) En route to the hospital B) Prior to transport C) During the primary assessment D) Immediately after the injuries are discovered

400

D) widespread dilation of the blood vessels causes blood to pool in the vascular beds
. Distributive shock occurs when: A) an injury causes restriction of the heart muscle and impairs its pumping function. B) severe bleeding causes tachycardia in order to distribute blood to the organs faster. C) temporary but severe vasodilation causes a decrease in blood supply to the brain. D) widespread dilation of the blood vessels causes blood to pool in the vascular beds

400

D) Rapid transport to a trauma center
A 25-year-old unrestrained female struck the steering wheel with her chest when her car hit a tree while traveling at a high rate of speed. She has signs and symptoms of shock, which you suspect are the result of intrathoracic bleeding. Which of the following interventions will provide this patient with the greatest chance for survival? A) High-flow oxygen administration B) Full immobilization of her spine C) Intravenous fluid administration D) Rapid transport to a trauma center

400

B) absent peripheral pulses
Clinical signs of compensated shock include all of the following, EXCEPT: A) cool and clammy skin. B) absent peripheral pulses. C) restlessness or anxiety. D) rapid, shallow breathing.

500

B) cardiogenic shock
Your patient has a decreased cardiac output and poor myocardial contractility. This will likely lead to ___________. A) hypovolemic shock B) cardiogenic shock C) neurogenic shock D) septic shock

500

A) the skin.
To protect vital organs, the body compensates by directing blood flow away from organs that are more tolerant of low flow, such as: A) the skin. B) the heart. C) the brain. D) the lungs.

500

D) hypothermia.
In an acute injury setting, neurogenic shock is commonly accompanied by: A) hypovolemia. B) tachycardia. C) diaphoresis. D) hypothermia.

500

C) Decompression of the injured side of the chest
