MPT Cardiopulmonary Physical Therapy 1 — Questions and Answers
Question 1: Which scale is commonly used to rate perceived exertion during cardiopulmonary rehabilitation?
- Visual Analog Scale
- Borg RPE Scale (Correct answer)
- Modified Ashworth Scale
- DASH Scale
Correct answer: Borg RPE Scale
The Borg Rating of Perceived Exertion (RPE) Scale (6–20) allows patients to self-rate exercise intensity, aiding exercise prescription in cardiac rehab.
Question 2: The 6-Minute Walk Test (6MWT) is used to assess:
- Maximum aerobic capacity (VO2 max)
- Submaximal functional exercise capacity (Correct answer)
- Pulmonary function volumes
- Cardiac output at rest
Correct answer: Submaximal functional exercise capacity
The 6MWT measures the distance walked in 6 minutes, reflecting submaximal functional aerobic capacity relevant to daily activities.
Question 3: Which breath sound indicates secretion accumulation in the larger airways?
- Fine crackles
- Wheeze
- Coarse crackles (rhonchi) (Correct answer)
- Stridor
Correct answer: Coarse crackles (rhonchi)
Coarse crackles (rhonchi) are low-pitched, gurgling sounds caused by secretions in the larger central airways and often clear with coughing.
Question 4: What is the target oxygen saturation range for most patients during cardiopulmonary physical therapy?
- 85–89%
- 90–95%
- ≥95% (Correct answer)
- 100%
Correct answer: ≥95%
SpO2 ≥95% is generally the target during exercise in cardiopulmonary PT; exercise is typically stopped if SpO2 drops below 88–90%.
Question 5: Pursed-lip breathing is used primarily to:
- Increase respiratory rate
- Slow exhalation and reduce air trapping in COPD (Correct answer)
- Strengthen inspiratory muscles
- Increase tidal volume immediately
Correct answer: Slow exhalation and reduce air trapping in COPD
Pursed-lip breathing creates back pressure that slows expiratory flow, reduces dynamic airway collapse, and decreases air trapping in COPD.
Question 6: Phase II cardiac rehabilitation typically begins:
- During acute hospitalization (days 1–3 post-MI)
- Shortly after hospital discharge, as outpatient supervised exercise (Correct answer)
- One year after a cardiac event
- Only after coronary artery bypass surgery
Correct answer: Shortly after hospital discharge, as outpatient supervised exercise
Phase II cardiac rehab is an outpatient, supervised exercise program beginning shortly after hospital discharge following a cardiac event.
