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 younger population can lead to devastating results
in elderly patients.
What is the most common mechanism of injury in the elderly? - ANS✔✔-
--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? - ANS✔✔---
advanced age, physical impairment, history of previous fall, medication
use, dementia, unsteady gait, and visual, cognitive impairment
Pre-existing conditions that affect morbidity and mortality include: -
ANS✔✔---cirrhosis, coagulopathy, COPD, ischemic heart disease, DM
Most of elderly traffic fatalities occur in the daytime and on weekends and
typically involve other vehicles. Why? - ANS✔✔---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.
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. - ANS✔✔---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? -
ANS✔✔---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? - ANS✔✔---20-40%
True or False? Mortality associated with small to moderate sized burns in
older adults remains high - ANS✔✔---True
Functional changes in cardiac system include declining function, decreased
sensitivity to catecholamines, atherosclerosis of coronary vessels,
increased afterload, fixed heart rate (beta blockers) - ANS✔✔---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 - ANS✔✔---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 - ANS✔✔---
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 - ANS✔✔---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) -
ANS✔✔---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 - ANS✔✔---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...... - ANS✔✔---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. - ANS✔✔---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.
