What are contributing factors to injuries related to blunt traumas? {Ans: The point of impact on the patient's body, the type of surface that is hit, the tissues ability to resist (bone versus soft tissue, air-filled versus solid organs), and the trajectory of force.}What are the three factors that contribute to the damage caused by penetrating trauma's? {Ans: The point of impact, the velocity and speed of impact, and the proximity to the object.}What is the minimum permissive hypertension and a trauma patient? {Ans: A systolic of greater than or equal to 90 MMHG}Describe the characteristics of obstructive shock {Ans: Obstructive shock is it mechanical problem that results from hypoperfusion of the tissue due to an obstruction in either the vasculature or the heart resulting in decreased cardiac output. Some causes include a tension pneumothorax, cardiac tamponade, or venous air embolism on the right side of the heart during systole in the pulmonary artery.Signs include anxiety, muffled heart sounds, JVD, hypertension, chest pain, difficulty breathing, or pulses paradoxes.}Define Cushing's triad {Ans: Bradycardia, progressive hypertension (widening pulse pressure), and decreased respiratory effort}Describe the characteristics of hypovolemic shock {Ans: Hypovolemia is caused by a decrease in
