Which parameter BEST reflects a patient's ventilatory reserve during a cardiopulmonary exercise test?
Answer: Breathing reserve (MVV minus peak VE)
Breathing reserve (MVV − peak VE) indicates how close a patient is to their maximum ventilatory capacity, reflecting ventilatory limitation.
A 6-Minute Walk Test is performed on a patient with pulmonary fibrosis. The MOST important physiologic variable to monitor during this test is:
Answer: Oxygen saturation via pulse oximetry
Patients with pulmonary fibrosis are prone to severe exercise-induced desaturation, making continuous SpO2 monitoring essential during the 6MWT.
The Borg RPE scale is used during cardiopulmonary rehabilitation. A patient reports an RPE of 13. This corresponds to which perceived exertion level?
Answer: Somewhat hard
On the original Borg 6–20 scale, a rating of 13 corresponds to 'somewhat hard,' which is a moderate intensity typically targeted in cardiac rehab.
A patient with a recent MI is in Phase I cardiac rehabilitation. Which activity is MOST appropriate during this phase?
Answer: Low-intensity ADLs and bedside range of motion
Phase I (inpatient) cardiac rehab focuses on low-intensity activities (1–2 METs) such as ADLs and gentle range of motion to prevent deconditioning without stressing the heart.
A therapist reviews a chest X-ray and notes opacification of the right lower lobe with an air bronchogram. This radiographic finding is MOST consistent with:
Answer: Lobar pneumonia
Air bronchograms within an area of opacification indicate air-filled bronchi surrounded by consolidated (fluid-filled) lung tissue, characteristic of lobar pneumonia.
During a physical therapy session, a patient suddenly develops tracheal deviation toward the right side, absent breath sounds on the left, and hypotension. The therapist should suspect:
Answer: Left-sided tension pneumothorax
Tension pneumothorax causes tracheal deviation away from the affected side due to mediastinal shift, along with absent breath sounds and hemodynamic compromise.
Which diaphragmatic breathing technique MOST effectively reduces accessory muscle use in a patient with COPD?
Answer: Pursed-lip breathing combined with diaphragmatic breathing
Pursed-lip breathing slows expiration and maintains positive airway pressure to prevent dynamic airway collapse, and when combined with diaphragmatic breathing reduces accessory muscle recruitment.
