P2 Trauma Midterm
| Question | Answer |
|---|---|
| Survival rates increase dramatically as time from initial injury to surgery decreases: | Golden period |
| Scene time in reference to the golden period | Platinum ten minutes |
| Commits resources to address all types of specialty trauma 24 hours a day, 7 days a week | Level I (regional trauma center) |
| Commits the resources to address the most common trauma emergencies with surgical capability available 24/7; stabilizes and transports specialty cases to the regional trauma center: | Level II (area trauma center) |
| Commits to specialty emergency department training and has some surgical capability but usually stabilitzes and transfers seriously injured trauma patients to a higher level trauma center as needed | Level III (community trauma center) |
| In remote areas, a small community hospital or medical care facility can be designated a trauma receiving facility, meaning that it stabilizes and prepares seriously injured trauma patients for transport to a higher level facility | Level IV (trauma facility) |
| A physical injury or wound caused by an external force or forces | trauma |
| The branch of physics dealing with objects in motion and energy exchanges that occur as these objects collide | Kinetics |
| Describes how objects in motion behave; a body in motion will remain in motion unless acted upon by an outside force | Newton’s First Law of Inertia |
| Trauma that occurs when kinetic energy forces, but not the object, enter the body and damage tissue | Blunt trauma |
| Trauma that occurs as an object physically enters the body and directly or indirectly injures tissue | Penetrating trauma |
| Injury occurs when impact abruptly stops a portion of the body while intertidal causes the remaining structures to continue in motion | Compression |
| Injury in which the tissues and fibers that hold organs and other structures together are pulled and injured or torn | Stretch |
| Injury occurs along edges of the impacting force or at organ attachments | Shear |
| Five phases of a vehicle collision | Vehicle, body, organ, secondary, additional impacts |
| Collision begins when a vehicle strikes an object or an object strikes the vehicle | Vehicle collision |
| Collision occurs when an occupant remains in motion and subsequently strikes the vehicle’s interior | Body collision |
| Collisions result as an occupant contacts the vehicle’s interior and/or restrains and slows or stops | Organ collision |
| Collision occurs when the occupant is struck by loose objects within the vehicle | Secondary collision |
| MOI in which the unrestrained occupant tenses their legs in preparation for the collision, unrestrained upper body pivots forward and upward, steering wheel impinges the femurs | Up and over |
| MOI in which the unrestrained occupant slides downward as the vehicle comes to a stop, the knees contact the firewall under the dashboard and absorb the initial impact | Down and under |
| What is considered the most common type of vehicle accident? | Frontal impact |
| Which type of vehicle collision is responsible for the most vehicular deaths? | Lateral impact |
| The study of projectiles in motion and their effects on objects they impact | Ballistics |
| The curved path a bullet follows after it is fired from a gun | Trajectory |
| Bullet meets air resistance as it travels through the air | Drag |
| Speed | Velocity |
| The portion of the bullet you would see if it traveled straight toward you | Profile |
| What organs are most affected by the blast wave? | Lungs, abdomen, ears |
| State of inadequate tissue perfusion | Shock |
| Supplying of oxygen and nutrients to the body tissues as a result of the constant passage of blood through capillaries | Perfusion |
| Phase of cardiac cycle when ventricles contract; force blood against arteries when ventricles contract | Systolic |
| Phase of cardiac cycle when ventricles relax and when cardiac filling and coronary perfusion occur; force of blood against arteries when ventricles relax | Diastolic |
| The pressure (volume) within the ventricles at the end of diastole | Preload |
| The resistance against which the heart must pump against | Afterload |
| How do you calculate a patient’s pulse pressure? | Systolic - diastolic |
| Contain about 13% of total blood volume and have a thick external layer (tunica adventitia) that helps determine the artery’s maximum diameter | Arteries |
| Contain about 64% of the blood volume; contain a small amount of both connective tissue and musculature in their walls | Veins |
| Contain about 7% for the vascular volume; microscopic vessels only large enough for red blood cells to pass through in single file. | Capillaries |
| Blunt, non-penetrating injuries that crush an damage small blood vessels | Contusion |
| Collection of blood beneath the skin or trapped within a body compartment | Hematoma |
| The causal equina is located: | Below the level of L2 |
| T/F: Linear fractures are small cracks in the cranium and represent about 80% of all skull fractures. | True |
| T/F: Le Fort fractures usually result in CSF leakage. | True |
