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

Continue ambulation and reassess in 2 minutes

Answer

Reduce walking speed by 50% and monitor

Answer

Discontinue PT services for the day

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

A high-pitched sound best heard at the aortic area

Answer

A mid-systolic click at the left sternal border

Answer

A late diastolic sound heard with the bell at the base

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

Avoid shoulder flexion beyond 90 degrees bilaterally

Answer

Limit bilateral shoulder abduction to 45 degrees

Answer

Restrict cervical rotation to prevent sternal stress

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

6-9

Answer

10-11

Answer

15-17

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

Decreased FEV1, decreased FEV1/FVC ratio, normal TLC

Answer

Normal FVC, decreased FEV1, decreased FEV1/FVC ratio

Answer

Increased RV, decreased FVC, normal FEV1/FVC ratio

Question 6

Which positioning strategy best reduces work of breathing for a patient with acute decompensated heart failure and orthopnea?

Accepted Answer

High Fowler's position (60-90 degrees)

Answer

Supine with legs elevated 30 degrees

Answer

Left lateral decubitus with head flat

Answer

Prone positioning with pillow support

Question 7

A 65-year-old cardiac patient is on a beta-blocker. How should the physical therapist modify exercise intensity prescription?

Accepted Answer

Use RPE scale rather than heart rate as the primary intensity guide

Answer

Use target heart rate based on age-predicted HRmax without modification

Answer

Add 20 bpm to the calculated target heart rate to compensate

Answer

Reduce exercise duration by 50% to account for blunted HR response
