EMT Chapter 12 JB Learning

Clinical signs of compensated shock include all of the following, EXCEPT:

absent peripheral pulses.

Basic causes of shock include:

All of these answers are correct.

The action of hormones such as epinephrine and norepinephrine stimulates _____ to maintain pressure in the system and, as a result, perfusion of all vital organs.

All of these answers are correct.

Which of the following MOST accurately describes septic shock?

Bacterial damage to the vessel wall, leaking blood vessels, and vasodilation

Compensated shock

Early stage of shock, Syncope

Syncope

Fainting

Shock

Hypoperfusion

Autonomic nervous system

Regulates involuntary body functions

Which of the following statements regarding anaphylactic shock is correct?

Subsequent exposure after sensitization often produces a more severe reaction.

Perfusion

Sufficient circulation to meet cell needs,

Neurogenic shock is caused by:

a radical change in the size of the vascular system.

You respond to a residence for a patient with a severe leg injury following an accident with a chainsaw. When you arrive, you find the patient, a 44-year-old male, lying supine in the backyard. He has a partial amputation of his right lower leg that is actively bleeding. The patient is conscious and breathing adequately; however, he is restless and his skin is diaphoretic. You should:

apply direct pressure to the wound.

A 56-year-old male is found semiconscious by his wife. Your assessment reveals that his respirations are rapid and shallow, his pulse is rapid and irregular, and his blood pressure is low. The patient's wife states that he complained of left arm pain and nausea the day before, but would not allow her to call 9-1-1. The MOST likely cause of this patient's present condition is:

cardiogenic hypoperfusion.

Regulation of blood flow is determined by:

cellular need.

Your assessment of an unresponsive patient reveals that her breathing is inadequate. Your MOST immediate action should be to:

check her airway for obstructions.

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.

Neurogenic shock occurs when:

failure of the nervous system causes widespread vasodilation.

You are transporting a 33-year-old male who was involved in a major motor vehicle crash. You have addressed all immediate and potentially life-threatening conditions and have stabilized his condition with the appropriate treatment. With an estimated time of arrival at the hospital of 20 minutes, you should:

reassess his condition in 5 minutes.

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:

repeat the epinephrine injection after consulting with medical control.

You are called to a construction site where a 27-year-old worker has fallen from the second floor. He landed on his back and is drifting in and out of consciousness. A quick assessment reveals no bleeding or blood loss. His blood pressure is 90/60 mm Hg with a pulse rate of 110 beats/min. His airway is open and breathing is within normal limits. You realize the patient is in shock. The patient's shock is due to an injury to the:

spinal cord.
