repeat the epinephrine injection after consulting with medical control
Cardiogenic shock may result from all of the following, EXCEPT:

B) increased preload.
C) heart attack.
D) poor contractility
B. increased preload
Hypovolemic shock caused by severe burns is the result of a loss of
Patients develop septic shock secondary to
poor vessel function and severe volume loss
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 100/64 mm Hg. Her skin is warm and moist. You should be MOST suspicious that she is experiencing
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
In infants and children, a capillary refill time (CRT) that is greater than ______ second(s) is a sign of poor peripheral perfusion
Capillary sphincters are
circular muscular walls that regulate blood flow through the capillaries.
When perfusion to the core of the body decreases
blood is shunted away from the skin.
Which of the following patients is in decompensated shock?
A) a 20-year-old female with absent radial pulses and dilated pupils
B) a 32-year-old male with anxiety and a systolic blood pressure of 110 mm Hg
C) a 23-year-old restless male with cool, clammy skin and tachycardia
D) a 28-year-old female with pale skin and rapid, shallow respirations
Which of the following injuries would MOST likely cause obstructive shock

it often indicates the loss of half of his or her blood volume
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 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
Which of the following MOST accurately describes septic shock
bacterial damage to the vessel wall, leaking blood vessels, and vasodilation
Shock is the result of:
hypoperfusion to the cells of the body
A construction worker fell approximately 30 feet. He is semiconscious with rapid, shallow respirations. Further assessment reveals deformity to the thoracic region of his spine. His blood pressure is 70/50 mm Hg, his pulse is 66 beats/min and weak, and his skin is warm and dry. In addition to spinal immobilization and rapid transport, the MOST appropriate treatment for this patient includes
assisted ventilation, thermal management, and elevation of the lower extremities
Which of the following would MOST likely result in hemorrhagic shock?
A) repeated diarrhea
B) severe vomiting
C) liver laceration
D) excessive sweating
