Shock is the result of:
hypoperfusion to the cells of the body.
the body’s maintenance of homeostasis.
temporary dysfunction of a major organ.
widespread constriction of the blood vessels.
Capillary sphincters are:
under complete control of the voluntary portion of the nervous system.
capable of dilating in order to increase perfusion to crucial body organs.
responsible for constricting to compensate for decreased cell perfusion.
circular muscular walls that regulate blood flow through the capillaries.
One of the primary waste products of normal cellular metabolism that must be removed from the body by the lungs is:
lactic acid.
carbon dioxide.
pyruvic acid.
carbon monoxide.
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.
Pulmonary edema and impaired ventilation occur during:
septic shock.
cardiogenic shock.
neurogenic shock.
anaphylactic shock.
Patients develop septic shock secondary to:
poor vessel function and severe volume loss.
an infection that weakens cardiac contractions.
failure of the blood vessels to adequately dilate.
weak vessel tone caused by nervous system damage.
Differentiate among the various types of shock. 11. A 70-year-old female was recently discharged from the hospital following a total hip replacement. Today, she presents with restlessness, tachycardia, and a blood pressure of 90/64 mm Hg. Her skin is hot and moist. You should be MOST suspicious that she is experiencing:
septic shock
pump failure
a local infection
decompensated shock
Differentiate among the various types of shock. 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.
In an acute injury setting, neurogenic shock is commonly accompanied by:
hypovolemia.
tachycardia.
diaphoresis.
hypothermia.
A 19-year-old male was stung multiple times by fire ants. He is experiencing obvious signs and symptoms of anaphylactic shock. You administer high-flow oxygen and give him epinephrine via intramuscular injection. Upon reassessment, you determine that his condition has not improved. You should:
transport him immediately and provide supportive care while en route.
consider that he may actually be experiencing an acute asthma attack.
repeat the epinephrine injection after consulting with medical control.
request a paramedic unit that is stationed approximately 15 miles away.
You are dispatched to a residence for a 40-year-old female who fainted. Upon your arrival, the patient is conscious and alert, and states that she is fine. Her husband tells you that she fainted after receiving news that her sister was killed in a car crash. You offer oxygen to the patient, but she refuses to accept it. At this point, your primary concern should be to:
determine if she was injured when she fainted.
provide emotional support regarding her sister.
advise her that she needs to go to the hospital.
obtain baseline vital signs and a medical history.
A 20-year-old male has a large laceration to his wrist. He is holding a blood-soaked towel over the wound, but it continues to bleed rapidly. You should:
apply pressure to the brachial artery.
apply a tourniquet proximal to the wrist.
administer high-flow supplemental oxygen.
wrap the towel with pressure bandages.
Your assessment of an unresponsive patient reveals that her breathing is inadequate. Your MOST immediate action should be to:
administer high-flow oxygen.
check her airway for obstructions.
move her to the ambulance stretcher.
ventilate her with a bag-mask device.
Which of the following is the ONLY action that can prevent death from a tension pneumothorax?
Early administration of high-flow oxygen
Rapid administration of intravenous fluids
Decompression of the injured side of the chest
Positive-pressure ventilation with a bag-valve mask
Cardiogenic shock occurs due to which of the following reasons?
Severe allergic reaction
Heart's inability to pump blood
Loss of blood volume
Infection in the bloodstream
Neurogenic shock is caused by damage to which part of the body?
Heart
Lungs
Spinal cord
Liver
Which type of shock is caused by a severe allergic reaction?
Anaphylactic shock
Cardiogenic shock
Neurogenic shock
Septic shock
Which of the following is NOT a sign of shock?
Rapid pulse
Warm, dry skin
Shallow breathing
Pale or clammy skin
What is the most common type of shock in animals caused by severe blood loss?
Cardiogenic shock
Hypovolemic shock
Septic shock
Anaphylactic shock
