Biomechanics - Is the general study of forces & their effects Kinematics - Is the study of energy transfer as it applies to ID'ing actual or potential injuries Mechanism of Injury (MOI) - Is how external forces are transferred to the body, resulting in injury Newton's 1st Law of Motion - A body @ rest, stays @ rest unless acted on by an outside force Newton's Second Law - The acceleration of a body is parallel & directly proportional to the net force acting on the body, is in the directi...

Why is a measure of serum lactate obtained in the initial assessment of the trauma patient? Answer: c - a) to measure oxygenation and ventilation b) to quantify the base deficit for the adequacy of cellular perfusion c) *to gauge end-organ perfusion and tissue hypoxia ** d) to determine the underlying cause of shock A trauma patient is restless and repeatedly asking "where am I?" vital signs upon arrival were BP 100/60 mm Hg, HR 96 beats/min, and RR 24 breaths/min. Her skin is cool and d...

A - Airway--edema, vomit/blood, loose teeth, tongue obstruction, vocalization. Look in mouth, clear all/suction, maintain c-spine, cricothyrotomy or intubate as needed. B - Breathing--chest rise (symmetrical), rate and depth, accessory muscles, breath sounds, skin color. Do supplemental o2, BVM, needle thoracentesis/chest tube, nonporous dressing taped 3 sides. C - Circulation--rate and quality (core pulse), skin color/temp/diaphoresis, external bleeding. Control bleeding, 2 large bore IVs ...

What is kinematics? - A branch of mechanics (energy transfer) that refers to motion and does not consider the concepts of force and mass of the object or body. What is Newton's First Law? - A body at rest will remain at rest. A body in motion will remain in motion until acted on by an outside force. What is the Law of Conservation of Energy? - Energy can neither be created nor destroyed. It is only changed from one form to another. What is Newton's Second Law? - Force equals mass multipl...

what is the key to high performance trauma team? - effective communication skilled communication, cooperation and coordination are the cornerstones of high-performance teams and high-quality trauma care when obtaining a history for an injured patient, understanding the kinematic concepts associated with the mechanism of injury and energy transfer can initially assist the trauma provider in what? - evaluating and anticipating the types of injury that may be present MOI and energy transfer c...

What is the key to a high performing trauma team? - effective communication rationale: skilled communication, cooperation, and coordination are the cornerstones of high- performance teams and high-quality trauma care When obtaining a history for an injured patient, understanding the kinematic concepts associated with the mechanism of injury and energy transfer can initially assist the trauma provider in: - evaluating and anticipating the types of injuries that may be present rationale: mec...

What is the key to a high-performance trauma team? A. Individual goals B. Use of TeamSTEPPS C. Identification of a single decision maker D. Effective communication - D. Effective communication When obtaining a history for an injured patient, understanding the kinematic concepts associated with the mechanism of injury and energy transfer can initially assist the trauma provider in: A. Evaluating and anticipating the types of injury that may be present B. Deciding whether law enforcement s...

Effective communication •Skilled communication, cooperation, and coordination are the cornerstones of high-performance teams and high-quality trauma care - What is the key to a high-performance trauma team? Reprioritize circulation before airway or breathing. •The across-the-room observation is done at the beginning of the primary survey to rapidly assess the need to reprioritize circulation before airway or breathing. This is done if uncontrolled external hemorrhage is identified - Th...

Primary concern when a person cannot stop coughing/clearing their throat following house fire/smoke? - Airway/Intubate Lab evidence of cellular perfusion - Base Excess (Less than -6 is BAD) Multiple people are in the ER of different ages who all go to the same church. They all have the same symptoms. What is the most likely cause? - Biologic Suspected shock type with a spinal cord injury - Distributive Shock (Includes neurogenic) Patient has GCS of 3, unequal pupils (one sluggish, one blow...

Energy forces: Tension - forces stretch by pulling at opposite ends. Example: Tensile strength describes the tissues ability to resist pulling apart when stretched. Tendons, ligaments, and muscles can tear when they are overstretched (Achilles tendon) Energy Forces: Compression - Compression forces crush by squeezing together. Example: Injuries to organs occur when the organs are crushed from surrounding internal organs or structures such as a seat belt worn up across the abdomen, causing c...
