The Borg Rating of Perceived Exertion (RPE) scale ranges from:
Answer: 6–20
The original Borg RPE scale ranges from 6 to 20, designed to correlate with heart rate (multiply by 10).
Which position best facilitates drainage of the right lower lobe posterior basal segment?
Answer: Prone with foot of bed elevated
The prone position with the foot of the bed elevated drains the posterior basal segments via gravity-assisted postural drainage.
A patient's SpO2 drops to 88% during exercise. The PTA should:
Answer: Stop exercise and notify the physical therapist
An SpO2 below 90% is a contraindication to continued exercise; the PTA must stop and report to the supervising PT.
Which breathing pattern is characteristic of Cheyne-Stokes respiration?
Answer: Cyclic crescendo-decrescendo with apneic pauses
Cheyne-Stokes respiration is a cyclical pattern of increasing then decreasing tidal volume followed by apnea.
Target heart rate for moderate-intensity exercise in a healthy 40-year-old is approximately:
Answer: 108–126 bpm
Using the 220-minus-age formula: max HR = 180 bpm; 60–70% of 180 = 108–126 bpm for moderate intensity.
A PTA notes bilateral crackles at lung bases on auscultation. This finding most likely indicates:
Answer: Pulmonary edema or heart failure
Bilateral basilar crackles are a classic sign of fluid accumulation from pulmonary edema or congestive heart failure.
