Patients develop septic shock secondary to: |
blood vessel leakage, dilation, and severe volume loss. |
Temporary, widespread vasodilation and syncope caused by a sudden nervous system reaction MOST accurately describes: |
psychogenic shock. |
A 59-year-old male presents with severe vomiting and diarrhea of 3 days' duration. He is confused and diaphoretic, and his radial pulses are absent. His blood pressure is 78/50 mm Hg. After applying 100% supplemental oxygen, you should: |
prepare for immediate transport. |
A 19-year-old male was stung multiple times by fire ants. He is experiencing obvious signs and symptoms of anaphylactic shock. You administer 100% oxygen and give him epinephrine via subcutaneous injection. Upon reassessment, you determine that his condition has not improved. You should: |
repeat the epinephrine injection after consulting with medical control. |
Which of the following MOST accurately describes septic shock? |
bacterial damage to the vessel wall, leaking blood vessels, and vasodilation |
All of the following conditions would make you suspect shock, EXCEPT: |
tachycardia |
Pulmonary edema and impaired ventilation occur during: |
cardiogenic shock. |
When assessing a patient with signs and symptoms of shock, it is MOST important to remember that: |
blood pressure may be the last measurable factor to change in shock. |
A 27-year-old male was stabbed in the chest during a disagreement at a poker game. As you approach him, you see that a knife is impaled in his chest. Before you make physical contact with the patient, it is MOST important to: |
follow standard precautions |
Hypovolemic shock caused by severe burns is the result of a loss of: |
Plasma |
In infants and children, a capillary refill time (CRT) that is greater than ______ second(s) is a sign of poor peripheral perfusion. |
2 |
Shock is the result of: |
hypoperfusion to the cells of the body. |
Hypotension in a child with blunt or penetrating trauma is particularly significant because: |
it often indicates the loss of half of his or her blood volume. |
One of the primary waste products of normal cellular metabolism that must be removed from the body by the lungs is: |
Carbon Dioxide |
Which of the following would MOST likely result in hemorrhagic shock? |
Liver laceration |
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 wond |
When the body senses a state of hypoperfusion, the sympathetic nervous system releases epinephrine, the effects of which include: |
Tachycardia |
Which of the following patients is in decompensated shock? |
a 20-year-old female with absent radial pulses and dilated pupils |
Clinical signs of compensated shock include all of the following, EXCEPT: |
Absent peripheral pulses. |
Cardiogenic shock may result from all of the following, EXCEPT: |
Increased preload |
Distributive shock occurs when: |
Widespread dilation of the blood vessels caused the blood to pool in the vascular beds |
When perfusion to the core of the body decreases: |
Blood is shunted away from the skin |
