What are the signs and symptoms of decompensated shock? {Ans: Decreased level of consciousness, hypertension, narrow pulse pressure, tachycardia with weak pulses, tachypnea, skin that is cool clammy and cyanotic, base access outside the normal range, and serum lactate levels greater than two to 4MMOL/L.}What are the four types of trauma related injuries? {Ans: Blunt, penetrating, thermal, or blast.}What causes the secondary effects of blast traumas? {Ans: Projectiles propelled by the explosion. Injuries include penetrating or blunt injuries or I penetration.}What is the relationship between mass and velocity to kinetic energy? {Ans: Kinetic energy is equal to 1/2 the mass multiplied the square of its velocity therefore when mass is doubled so is the net energy, however, when velocity is doubled energy is quadrupled.}What causes quinary effects of blasts traumas? {Ans: Those associated with exposure to hazardous materials from radioactive, biologic, or chemical components of a blast. Injuries include a variety of health effects depending on agent.}What is the minimum permissive oxygenation level of a trauma patient? {Ans: Greater than or equal to 94%}
