ATLS EXAM (QUESTIONS AND ANSWERS A+ GRADED 100% VERIFIED) True or false? Although the mechanism of injury may be similar to those for the younger population, data shows increased mortality with similar severity of injury in older adults. ANS: True In the elderly population, what is decreased physiological reserve? ANS: aging is characterized by impaired adaptive and homeostatic mechanisms that caused an increased susceptibility to the stress of injury. Insults tolerated by the younge...

Types of body damage Direct; Indirect; Minor; Major Direct Damage Results in direct contact with an object. Holes, tears, gouges, and scratches are typical. Generally 10% of collisions result in direct damage Indirect Damage Results from direct damage. Impact cause another panel to lift, buckle, or tear. Rear end collision may result in damage near middle of car Minor Damage Involves little repair time and skill to complete Major Damage Requires more: time, s...
