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%
moderate = 40-60%
vigorous = 60-90%
HRR method - Answer ((HRpeak - HRrest) x %intensity) + HRrest
resistance FITT - Answer 2-3 days/week
10-15 reps for middle-aged adults
flexibility FITT - Answer 2/3 days/week
30-60 secs
pregnancy maximal test: is physician supervision necessary? - Answer for all pregnant
woman, yes.
ABI's (supine prior to exercise) levels - Answer normal >1.0
moderate .8 - .9
mod. severe .5 - .8
severe <.5
ABI's post-exercise - Answer normal No change
moderate >.5
mod. severe >.2
severe <.2
**rest for 15 minutes post-exercise, then calculate again
PAD FITT - Answer weight-bearing 3-5 days/week, resistance >2
