DPT Cardiovascular & Pulmonary PT 2

Question 1

A patient with COPD has a resting SpO2 of 88%. During ambulation, SpO2 drops to 82%. What is the most appropriate immediate action?

Accepted Answer

Stop activity and apply supplemental oxygen

Answer

SpO2 below 88% during exercise warrants stopping activity and applying supplemental oxygen to prevent hypoxic complications.

Question 2

Which auscultation finding is most consistent with a left ventricular S3 heart sound in a patient with heart failure?

Accepted Answer

A low-pitched early diastolic sound best heard at the apex

Answer

An S3 is a low-pitched early diastolic sound (ventricular gallop) best heard at the cardiac apex with the bell of the stethoscope.

Question 3

A patient post-CABG is 4 days post-op. Which sternal precaution is MOST critical during upper extremity exercises?

Accepted Answer

Avoid resisted bilateral upper extremity pushing or pulling

Answer

Resisted bilateral UE activities (pushing/pulling) create the greatest sternal stress and risk sternal dehiscence in early post-CABG recovery.

Question 4

When using the Borg Rating of Perceived Exertion (RPE) scale during cardiac rehab, which RPE range corresponds to moderate intensity exercise?

Accepted Answer

12-14

Answer

An RPE of 12-14 ('somewhat hard') on the 6-20 Borg scale corresponds to moderate intensity exercise, roughly 60-70% of HRmax.

Question 5

A patient with pulmonary fibrosis demonstrates a restrictive ventilatory pattern. Which PFT findings are expected?

Accepted Answer

Decreased FVC, normal FEV1/FVC ratio, decreased TLC

Answer

Restrictive lung disease shows decreased FVC and TLC with a preserved or elevated FEV1/FVC ratio, unlike the obstructive pattern.
