EXAM
high risk @ moderate & vigorous intensity: what/who is needed - answer-medical exam,
exercise test & MD supervision prior to exercise
moderate risk @ vigorous intensity: what/who is needed - answer-only medical exam
prior to exercise
low risk @ moderate & vigorous intensity: what/who is needed - answer-nothing
moderate risk @ moderate intensity: what/who is needed - answer-nothing
which patients (risk stratified) can be supervised by non-physician health care
professionals if professionals are specifically trained in CET & physician is
readily/immediately available? - answer-all risk groups can be; low risk can be
supervised w/o physician immediately available
who should have PFT's done? - answer-all smokers <45y.o & anyone presenting with
dyspnea
ECG monitoring during test - answer-recorded last 15secs of each stage
BP monitoring during test - answer-measured/recorded last 45secs of each stage
HR monitoring during test - answer-recorded last 5secs of each stage
, ECG monitoring after test - answer-monitored continuously, recorded immediately post
exercise, during last 15secs of 1st minute then every 2 minutes thereafter
BP monitoring after test - answer-measured & recorded immediately post exercise then
every 2 minutes thereafter
HR monitoring after test - answer-monitored continuously then recorded during last
5secs of each minute
technetium (tc) -99m - answer-comparison of rest & stress imaging permits ID of fixed &
reversible perfusion abnormalities as well as differentiation; permits higher does with
less radiation exposure; preferred imaging agent
thallum 201 - answer-circulates myocardium showing images of where lack/inadequate
blood flow is; shows images of inadequate perfusion
dobutamine - answer-elicits wall motion abnormalities by increasing HR & therefore
myocardial O2 demand; infused intravenously with dose increased gradually until
maximal does or endpoint is acheived
adenosine (dipyridamole) - answer-causes maximal coronary vasodilation in normal
epicardial arteries; rest images then compared with imaging obtain after coronary
vasodilation
optimal ExRx - answer-cardiorespiratory fitness (CRF), muscular strength, muscular
endurance, flexibility, body comp, & neuromotor fitness (gradual progression of
volume/intensity)
overload principle - answer-states exercise below minimum intensity will not challenge
body sufficiently to result in changes in physiologic parameters
intensity (light, moderate, vigorous( - answer-light = 30-40%
