6. _____ shock is the most common type of shock immediately after traumatic
increase deceleration speed. injury.
add deceleration distance. - ANSWER: reduce acceleration injuries. Distributive Septic Cardiogenic Hypovolemic - ANSWER: Hypovolemic
2. Which of the following statements best describes knife wounds? Their velocity 7. Which findings suggest a trauma patient is experiencing cardiogenic shock?
is _____, the temporary cavity _____, and damage _____.
low; depends on the size of the knife; is usually extensive
Bradycardia, cyanosis, and elevated mean arterial pressure
low; is insignificant; is limited to structures directly in object's path
High shock index, mottling, and hypotension
high; will be small; affects structures at some distance from the wound tract
Tachycardia, flushing, and widened pulse pressure
high; may be massive; results in widespread tissue destruction - ANSWER: low;
is insignificant; is limited to structures directly in object's path Pallor, course breath sounds, and hypertension - ANSWER: High shock index,
mottling, and hypotension
4. Injury to which body structure is commonly a DELAYED finding in the blast
trauma patient? 8. A multisystem trauma patient has become progressively tachycardic and
hypotensive one week after hospital admission. Pulse pressure is wide. The most
Heart likely explanation for this finding is
Bladder
Bowel dehydration.
Spleen - ANSWER: Bowel fat embolism syndrome.

9. Normalizing a trauma patient's body temperature helps control bleeding because Pulse pressure, afterload, shock index, and blood pressure
hypothermia
Heart rate, preload, contractility, and afterload
Preload, mean pressure, heart rate, and central venous pressure
produces shivering and makes platelets hyperactive.
Contractility, systolic pressure, shock index, and pulse pressure - ANSWER:
causes platelet dysfunction and clotting system failure. Heart rate, preload, contractility, and afterload
stimulates the clotting cascade and reduces blood pressure.
increases tissue oxygen consumption and cold diuresis. - ANSWER: causes 13. Trauma resuscitation is considered complete when hemorrhage is controlled,
platelet dysfunction and clotting system failure. the patient has normal vital signs, and
10. What are the 3 components of the "trauma triad of death"? body temperature has been stabilized.
hemoglobin level is greater than 8 g/dL.
Coagulopathy, hypothermia, and acidosis aerobic metabolism is reestablished.
Hypothermia, alkalosis, and coagulopathy the Glasgow Coma Scale score exceeds 13. - ANSWER: aerobic metabolism is
reestablished.
Alkalosis, hyperthermia, and tissue injury
Tissue injury, hyperthermia, and acidosis - ANSWER: Coagulopathy,
hypothermia, and acidosis 14. A patient with posterior rib fractures is at the highest risk for concomitant
fractures of the
11. Compensatory responses to hypovolemic shock include
sternum.
T-spine.
vasoconstriction, tachycardia, and oliguria.
clavicles.
immune system activation, water retention, and bradycardia.
ribs 1 and 2. - ANSWER: T-spine.
tachycardia, diuresis, and hypoglycemia.
fluid shifts, histamine release, and increased urine output. - ANSWER:
vasoconstriction, tachycardia, and oliguria. 15. A motocross racer hit a ditch at high speed. The rider's chest was thrown
against the handlebars. Which assessment finding indicates the patient has a flail
chest?
