- Q1Which of the following MOST accurately describes septic shock?Bacterial damage to the vessel wall, leaking blood vessels, and vasodilationBacterial infection of the nervous system with widespread vasodilationViral infection of the blood vessels, vascular damage, and vasoconstrictionWidespread vasoconstriction and plasma loss due to a severe viral infection120s
- Q2Neurogenic shock occurs when:massive vasoconstriction occurs distal to a spinal cord injurythere is too much blood to fill a smaller vascular containerfailure of the nervous system causes widespread vasodilationthe spinal cord is severed and causes massive hemorrhaging120s
- Q3Which of the following statements regarding anaphylactic shock is correct?Anaphylactic shock occurs immediately after a person is sensitized to an allergenSensitized people will experience less severe reactions upon subsequent exposureSubsequent exposure after sensitization often produces a more severe reactionAnaphylactic shock is caused by immune system failure due to a toxic exposure120s
- Q4Clinical signs of compensated shock include all of the following, EXCEPTrapid, shallow breathingcool and clammy skinrestlessness or anxietyabsent peripheral pulses120s
- Q5You 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:take his vital signs in 15 minutesreassess his condition in 5 minutesrepeat your secondary assessmentarrange for an ALS rendezvous120s
- Q6You 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:administer 100% supplemental oxygenimmediately evaluate his airwayassess the rate and quality of his pulseapply direct pressure to the wound120s
- Q7A 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:a ruptured aortic aneurysmsevere septic hypoperfusionacute myocardial infarctioncardiogenic hypoperfusion120s
- Q8A 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:consider that he may actually be experiencing an acute asthma attackrequest a paramedic unit that is stationed approximately 15 miles awayrepeat the epinephrine injection after consulting with medical controltransport him immediately and provide supportive care while en route120s
- Q9You 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:obtain baseline vital signs and a medical historydetermine if she was injured when she faintedprovide emotional support regarding her sisteradvise her that she needs to go to the hospital120s
- Q10Your assessment of an unresponsive patient reveals that her breathing is inadequate. Your MOST immediate action should be to:administer high-flow oxygenventilate her with a bag-valve maskmove her to the ambulance stretchercheck her airway for obstructions120s
- Q11Inadequate circulation of blood throughout the body is called ________.perfusionhypotensionhypoxiashock120s
- Q12What are the three components of the “perfusion triangle”?Arteries, veins, capillariesHeart, blood vessels, bloodPlasma, red blood cells, plateletsHeart, brain, lungs120s
- Q13You suspect your patient is in shock. You note the patient's skin is pale. This is likely due to ___________.peripheral vasodilationhypothermiaan increased heart rateperipheral vasoconstriction120s
- Q14Shock due to severe infection is called ________.septic shockneurogenic shockanaphylactic shockhypovolemic shock120s
- Q15Your patient has a decreased cardiac output and poor myocardial contractility. This will likely lead to ___________hypovolemic shockseptic shockcardiogenic shockneurogenic shock120s
