CORRECT {VERIFIED} ANSWERS NEWEST//ALREADY GRADED
A+
1. Helmets and automobile airbags work because they
prevent blows to the head.
reduce acceleration injuries.
increase deceleration speed.
add deceleration distance. - 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 - 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
Bladder
Bowel
Spleen - 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. - 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 - 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 - 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. - 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. - 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
Tissue injury, hyperthermia, and acidosis - ANSWER-Coagulopathy, hypothermia, and acidosis
