Pulmonary Rehabilitation Flashcards

According to evidence-based guidelines, what is the recommended minimum duration for a supervised pulmonary rehabilitation program to achieve clinically significant improvements in exercise capacity and health-related quality of life?

Answer: 6 to 8 weeks

Major guidelines, including those from the American Thoracic Society/European Respiratory Society, recommend a program duration of at least 6 to 8 weeks, with sessions typically held two to three times per week, to achieve meaningful and lasting physiological and psychological benefits.

A 74-year-old patient with severe, stable COPD is referred to pulmonary rehabilitation. Which of the following co-existing conditions represents an absolute contraindication to beginning the exercise training component of the program?

Answer: Unstable angina

Unstable angina is a serious cardiac condition that makes vigorous exercise unsafe and is considered an absolute contraindication. The other conditions are challenges that may require program modification (e.g., supplemental oxygen, alternative exercises for arthritis) but are not absolute contraindications.

A COPD educator is working with a patient during a lower extremity exercise session on a treadmill. To ensure the patient is exercising at an appropriate and safe intensity, which tool is most commonly used to titrate effort?

Answer: The modified Borg Dyspnea Scale

The modified Borg Dyspnea Scale (typically aiming for a level of 3-4 on a 0-10 scale) is the preferred method for titrating exercise intensity in COPD patients. Heart rate can be an unreliable indicator due to deconditioning, medications, and hypoxemia. FEV1 and CAT scores are assessment tools, not for real-time exercise monitoring.

A patient is nearing the end of their 8-week pulmonary rehabilitation program and has shown significant improvement in their 6-minute walk distance and quality of life scores. What is the MOST critical element for sustaining these benefits long-term?

Answer: Continuing a prescribed home exercise regimen

While psychosocial support and nutrition are components of rehabilitation, the physiological gains in exercise capacity and muscle function will diminish without ongoing physical activity. Adherence to a long-term home exercise plan is crucial for maintaining the benefits achieved in a formal program.

Which of the following represents a primary, evidence-based outcome and a main goal of pulmonary rehabilitation for a patient with COPD?

Answer: A reduction in symptoms and improved exercise tolerance

The main goals and most consistently demonstrated benefits of pulmonary rehabilitation are a reduction in the sensation of dyspnea, improvement in exercise capacity, and enhanced health-related quality of life. It does not reverse the underlying lung pathology or significantly change FEV1.

During a supervised exercise session, a patient with COPD suddenly becomes very pale, reports dizziness, and has an oxygen saturation that drops from 92% to 84%. What is the educator's most appropriate immediate action?

Answer: Stop the exercise immediately, have the patient sit, and assess vital signs

Patient safety is paramount. The combination of symptoms (pallor, dizziness) and a significant, acute drop in oxygen saturation are warning signs. The exercise must be stopped immediately to allow for patient assessment (vital signs, level of distress) and to determine the next steps, which may include oxygen and medical intervention.
