A 66-year-old client with moderate COPD begins treadmill walking. After 8 minutes at RPE 12, you observe increased breathing rate and pursed-lip breathing. Which monitoring step is MOST appropriate?
Why each option is right or wrong
Pick an answer. Then tap any option to read its explanation, the wrong ones included.
A — Not this one. A dyspnea rating does not show oxygen saturation, the main safety concern with COPD.
B — Not this one. Pursed-lip breathing is a technique COPD patients use to control breathing; it is not a contraindication.
C — Correct. Pulse oximetry shows whether saturation is falling below the commonly used 88–90% threshold, the objective safety check for COPD. RPE 12 with pursed-lip breathing alone is not a reason to stop.
D — Not this one. Heart rate does not capture the main COPD risk, which is desaturation.
E — Not this one. Stopping for expected breathing changes at RPE 12 is overly cautious and removes the training stimulus.
