Exam 1 Flashcards
1
Q
Phase I cardiac rehab:
A
Goal: make sure patient is safe/stable to go home
- no signs/sx of activity intolerance during self-care ADLs and light exercise
- self care activities
- progressive ambulation
- AROM exercise; flexibility
- Patient education
2
Q
adverse responses to exercise:
A
- DBP >110 mm Hg
- decrease in SBP >10 mm Hg
- significant arrythmias with or without associated signs/symptoms
- second or third degree heart block
- angina, marked dyspnea, or ECG changes suggestive of ischemia
3
Q
appropriate level of exercise after heart procedure:
A
2-4x a day MI: HR at rest +20bpm CABG: HR at rest +30bpm <120 bpm 3-5 min. bouts 1:2 rest ratio -progress to 10-15 min walking
4
Q
abnormal SpO2 during exercise:
A
decrease >5%
-stop exercise if <80%
5
Q
Phase II cardiac rehab
A
- outpatient
- supervised and monitored exercise
- social support
- pt education for risk factor reduction
6
Q
Phase III cardiac rehab
A
- supervised unmonitored exercise
- continuation of previous interventions
7
Q
phase IV cardiac rehab
A
-unsupervised unmonitored exercise
8
Q
absolute criteria for stopping exercise
A
- EKG changes (ST-segment elevation without preexisting Q waves; sustained v-tach; arrhythmias; heart block with hemodynamic compromise
- > 10 mmHg drop in SBP (in conjunction with ischemia)
- angina
- ataxia
- dizziness
- faintness
- cyanosis/pallor
9
Q
relative criteria for stopping exercise
A
- ST segment horizontal or downsloping >2 mm
- multifocal ectopi, ventricular triplets, bradyarrhythmias, supraventricular tachycardia
- > 10 mmhg drop in SBP (no ischemia)
- hypertensive response (>250 / >115
- fatigue
- SOB
- wheezing
- leg cramps
