1. Helmets and automobile airbags work because
they prevent blows to the head.
Reduce acceleration
injuries. Increase
deceleration speed.
Add deceleration distance. - crt.answer-reduce 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 - crt.answer-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
Bladde
r
bowel
Spleen - crt.answer-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. - crt.answer-cellular oxygen demand is
greater than supply.
, 6. shock is the most common type of shock immediately after traumatic
injury. Distributive septic cardiogenic hypovolemic - crt.answer-hypovolemic
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, course breath sounds, and hypertension - crt.answer-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. - crt.answer-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. - crt.answer-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
