ATLS EXAM QUESTIONS WITH COMPLETE SOLUTIONS VERIFIED GRADED A+
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.
True
In the elderly population, what is decreased p...
What is the most common mechanism of injury in the elderly?
Fall. Nonfatal falls are common in women and fractures are common in women who fall.
Falls are the most common cause of TBI.
In the elderly population, what are risk factors for falls?
advanced age, physical impairment, history of previous fall, medication use, dementia,
unsteady gait, and visual, cognitive impairment
Most of elderly traffic fatalities occur in the daytime and on weekends and
typically involve other vehicles. Why?
,Older people drive on more familiar roads and at lower speeds and tend to drive during
the day. Older people have slower reaction time, a larger blind spot, limited cervical
mobility, decreased hearing, and cognitive impairment.
True or False? Mortality associated with small to moderate sized burns in older
adults remains high
True
Spilled hot liquids on the leg, which in younger patients may re-epithelialize due
to an adequate number of hair follicles, will result in a full thickness burn in older
patients.
this is true
Airway-patients may have dentures that may loosen or obstruct the airway. If
dentures are not obstructing the airway, leave them in place for what?
bag mask ventilation, as it improves mask fitting.
When preforming rapid sequence intubation, the dose of benzos, barbiturates,
and other sedatives should be reduced to what percentage to minimize the risk of
cardiovascular depression?
20-40%
Functional changes in cardiac system include declining function, decreased
sensitivity to catecholamines, atherosclerosis of coronary vessels, increased
afterload, fixed heart rate (beta blockers)
this results in lack of classic response to hypovolemia, risk for cardiac ischemia,
elevated BP at baseline, and increased risk of dysrythmias.
,Functional changes in pulmonary system include decreased elastic recoil,
reduced residual capacity, decreased gas exchange and decreased cough reflex
thus they are at increased risk for respiratory failure, increased risk for pneumonia, and
poor tolerance to rib fractures
Functional changes in renal system include loss of renal mass, decreased GFR,
and decreased sensitivity to ADH and aldosterone
resulting in drug dosing for renal insufficiency, decreased ability to concentrate urine,
increased risk for AKI and urine flow may be normal with hypovolemia
Functional changes to MSK include loss of lean body mass, osteoporosis,
changes in joints and cartilage, c spine degenerative changes and loss of skin
elastin and subcutaneous fat
resulting in increased risk for fractures, decreased mobility, difficulty for oral intubation,
risk of skin injury, increased risk for hypothermia, challenges in rehabiliation
Functional changes in Endocrine system include decreased production and
response to thyroxin and decreased dehydroepiandrosterone (DHEA)
resulting in occult hypothyroidism, relative hypercortisone states and increased risk of
infection
True or false: Arthritis can complicate the airway and cervical spine. Patients can
have multilevel degenerative changes affecting disk spaces and posterior
elements associated with severe central canal stenosis, cord compression, and
myelomalacia
true
, In elderly population, due to their changes in pulmonary system, placing a gauze
between gums and cheek to achieve seal when using bag valve mask ventilation
is okay. In addition, because aging causes a suppressed heart rate response to
hypoxia......
respiratory failure may present insidiously in older adults.
Age related changes in the cardiovascular system place the elderly trauma
patient at significant risk for being inaccurately categorized as hemodynamically
stable.
Elderly patients have a fixed heart rate and fixed cardiac output, thus, their response to
hypovolemia will involve increasing their systemic vascular resistance. Furthermore,
since older patients have HTN, an acceptable BP may truly reflect a hypotensive state.
A systolic BP of 110 is to be utilized as the threshold for identifying hypotension in
patients 65 and older.
Do no equate blood pressure with shock in older patients
BP in older patients may look normal due to the medications they are on. Use lactate
and base deficit to evaluate for evidence of shock
what 2 factors place elderly patients at risk for intracranial hemorrhage?
aging causes dura to become more adherent to the skull increasing risk of injury and
older patients are on anticoagulant and antiplatelet medications.
Loss of subcutaneous fat, nutritional deficiencies, chronic medical conditions
place elderly patients as risk for hypothermia and complications for immobility.
Rapid evaluation and when possible early liberation from spine boards and cervical
collars will minimize complications.
