,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.
Rationale: Helmets and airbags do not stop the motion but reduce the rate of acceleration or
deceleration during a collision. By doing so, they lower the forces exerted on the brain and other tissues,
which significantly reduces the risk of traumatic brain injury. Their function is protective, not to increase
speed or directly prevent impact.
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.
Rationale: Knife wounds are low-velocity injuries. They create a small temporary cavity that does not
expand significantly. Damage is confined mostly to structures directly in the knife’s path, unlike high-
velocity projectiles that can affect tissues at a distance due to cavitation.
, 4. Injury to which body structure is commonly a DELAYED finding in the blast trauma patient? Heart,
Bladder, Bowel, Spleen.
Answer: Bowel.
Rationale: Blast injuries often cause immediate damage to solid organs like the spleen or liver. Hollow
organs, such as the bowel, may show delayed perforation or ischemia. These injuries can manifest hours
to days after the initial trauma, making them important to monitor over time.
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.
Rationale: Shock is a physiological state where tissues do not receive adequate oxygen relative to their
metabolic needs. This imbalance can lead to cellular dysfunction and organ failure. It is not merely
related to ATP levels or metabolic pathways alone but the mismatch of oxygen supply and demand.
6. ___ shock is the most common type of shock immediately after traumatic injury. Distributive, Septic,
Cardiogenic, Hypovolemic.
Answer: Hypovolemic.
Rationale: Trauma often causes hemorrhage, leading to a drop in circulating blood volume.
