When the body senses a state of hypoperfusion, the sympathetic nervous system releases epinephrine, the effects of which include:tachycardia
Which of the following MOST accurately describes septic shock? a) Widespread vasoconstriction and plasma loss due to a severe viral infection b) Bacterial damage to the vessel wall, leaking blood vessels, and vasodilation c) Bacterial infection of the nervous system with widespread vasodilation d) Viral infection of the blood vessels, vascular damage, and vasoconstrictionb) Bacterial damage to the vessel wall, leaking blood vessels, and vasodilation
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.
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 70-year-old female was recently discharged from the hospital following a total hip replacement. Today, she presents with an altered mental status, 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:septic shock.
Hypovolemic shock caused by severe burns is the result of a loss of:plasma
Which of the following statements regarding anaphylactic shock is MOST correct? a) Anaphylactic shock is the result of immune system failure due to a toxic exposure b) Sensitized people will experience less severe reactions upon subsequent exposure c) Subsequent exposure following sensitization often produces more severe reactions d) Anaphylactic shock occurs immediately after a person is sensitized to an allergenc) Subsequent exposure following sensitization often produces more severe reactions
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.
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 conditions has the GREATEST potential to be accompanied by internal bleeding? a) A heart attack b) Severe infection c) Spinal injury d) Anaphylaxisc) Spinal injury
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 is experiencing 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) 100% oxygen administration b) Full immobilization of her spine c) Rapid transport to a trauma center d) Applying and inflating the PASG c) Rapid transport to a trauma center
Shock is the result of:Hypoperfusion to the cells of the body
Patients develop septic shock secondary to:poor vessel function and severe volume loss.
When perfusion to the core of the body decreases:blood is shunted away from the skin
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.
In infants and children, a capillary refill time (CRT) that is greater than ___ seconds is a sign of poor peripheral perfusion.2
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
Neurogenic shock occurs when:failure of the nervous system causes widespread vasodilation.
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:adhere to BSI precautions
