TCAR POST TEST1. Helmets and automobile airbags work because they
prevent blows to the head.
reduce acceleration injuries.
increase deceleration speed.
add deceleration distance. - ANS reduces acceleration injuries.
2. Which of the following statements best describes knife wounds? Their velocity is _____, the
temporary cavity _____, and damage _____.
low; depends on the size of the knife; is usually extensive
low; is insignificant; is limited to structures directly in object's path
high; will be small; affects structures at some distance from the wound tract
high; may be massive; results in widespread tissue destruction - ANS low; is insignificant; is
limited to structures directly in object's path
4. Injury to which body structure is commonly a DELAYED finding in the blast trauma patient?
Heart
Bladder
Bowel
Spleen - ANS Bowel
5. Shock occurs when
the sodium-potassium pump fails.
ATP levels are less than lactic acid levels.
cellular oxygen demand is greater than supply.
aerobic metabolism exceeds anaerobic metabolism. - ANS cellular oxygen demand is greater
than supply.
6. _____ shock is the most common type of shock immediately after traumatic injury.
Distributive Septic Cardiogenic Hypovolemic - ANS Hypervolemic
7. Which findings suggest a trauma patient is experiencing cardiogenic shock?
Bradycardia, cyanosis, and elevated mean arterial pressure
High shock index, mottling, and hypotension
Tachycardia, flushing, and widened pulse pressure
Pallor, coarse breath sounds, and hypertension - ANS High shock index, mottling, and
hypotension
, 8. A multisystem trauma patient has become progressively tachycardic and hypotensive one
week after hospital admission. Pulse pressure is wide. The most likely explanation for this
finding is
dehydration.
fat embolism syndrome.
surgical site bleeding.
sepsis. - ANS sepsis.
9. Normalizing a trauma patient's body temperature helps control bleeding because hypothermia
produces shivering and makes platelets hyperactive.
causes platelet dysfunction and clotting system failure.
stimulates the clotting cascade and reduces blood pressure.
increases tissue oxygen consumption and cold diuresis. - ANS causes platelet dysfunction and
clotting system failure.
10. What are the 3 components of the "trauma triad of death"?
Coagulopathy, hypothermia, and acidosis
Hypothermia, alkalosis, and coagulopathy
Alkalosis, hyperthermia, and tissue injury
Tissue injury, hyperthermia, and acidosis - ANS Coagulopathy, hypothermia, and acidosis
11. Compensatory responses to hypovolemic shock include
vasoconstriction, tachycardia, and oliguria.
immune system activation, water retention, and bradycardia.
tachycardia, diuresis, and hypoglycemia.
fluid shifts, histamine release, and increased urine output. - ANS vasoconstriction, tachycardia,
and oliguria.
12. What four factors determine a patient's cardiac output?
Pulse pressure, afterload, shock index, and blood pressure
Heart rate, preload, contractility, and afterload
Preload, mean pressure, heart rate, and central venous pressure
Contractility, systolic pressure, shock index, and pulse pressure - ANS Heart rate, preload,
contractility, and afterload
13. Trauma resuscitation is considered complete when hemorrhage is controlled, the patient has
normal vital signs, and
body temperature has been stabilized.
