Mixed Deck — All COPD Topics Flashcards

Which pharmacological agent is considered first-line for relieving refractory dyspnea in end-stage COPD patients?

Answer: Morphine (low-dose oral or parenteral)

Low-dose systemic opioids, particularly morphine, have the strongest evidence base for palliating refractory dyspnea in end-stage COPD.

Which validated tool is most commonly used to assess dyspnea severity in COPD patients receiving palliative care?

Answer: Modified Medical Research Council (mMRC) Dyspnea Scale

The mMRC Dyspnea Scale is the most widely used validated tool for grading dyspnea severity and guiding palliative interventions in COPD.

Which stage of the Transtheoretical Model (TTM) describes a COPD patient who acknowledges smoking is harmful but is not planning to quit in the next 30 days?

Answer: Contemplation

The contemplation stage is characterized by awareness of the problem and consideration of change but without commitment to action within 30 days.

A COPD patient is diagnosed with lung cancer. Which COPD-related factor most increases lung cancer risk?

Answer: Airflow obstruction and chronic airway inflammation

Chronic airway inflammation and structural lung changes from airflow obstruction create a microenvironment that significantly increases lung cancer susceptibility.

An advance directive that specifically documents a patient's wishes regarding mechanical ventilation and resuscitation in COPD is best described as a:

Answer: POLST (Physician Orders for Life-Sustaining Treatment)

A POLST form translates patient wishes into actionable medical orders, including decisions about ventilation and CPR, making it actionable across care settings.

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 COPD educator is teaching a patient the 'huff cough' technique for airway clearance. Which instruction is a key part of this maneuver?

Answer: "After a deep breath, exhale forcefully while making a 'ha, ha, ha' sound."

The huff cough, or forced expiration technique, involves taking a medium to deep breath and then contracting the abdominal muscles to force the air out in short, sharp exhalations with an open glottis, often making a 'ha' or 'huff' sound. This is less fatiguing than a traditional cough and more effective at moving mucus from the smaller airways.

A COPD patient is newly diagnosed with anxiety disorder. Which non-pharmacological intervention is most supported by evidence for improving dyspnea-related anxiety?

Answer: Cognitive behavioral therapy (CBT)

CBT has strong evidence for reducing anxiety and dyspnea perception in COPD patients and is the preferred non-pharmacological approach.

During a routine follow-up, a COPD educator assesses a patient who states, 'I walk slower than other people my age because of my breathlessness, and I have to stop for breath when walking at my own pace on level ground.' This statement corresponds to which grade on the mMRC Dyspnea Scale?

Answer: Grade 2

Grade 2 on the mMRC Dyspnea Scale is defined by the patient walking slower than people of the same age on level ground because of breathlessness, or having to stop for breath when walking at their own pace on the level.

Which imaging study is most useful to rule out comorbidities (e.g., lung cancer) in COPD?

Answer: High-resolution CT (HRCT)

While a chest X-ray can show some signs of emphysema, High-resolution CT (HRCT) provides much more detailed images of the lung parenchyma and airways. It is superior for accurately assessing the extent of emphysema and bronchiectasis, and crucially, for detecting or ruling out other significant lung pathologies like lung cancer, which is common in COPD patients.

Which lab test is recommended for patients with early-onset COPD or family history?

Answer: Alpha-1 antitrypsin level

Alpha-1 antitrypsin deficiency is a genetic condition that can cause early-onset emphysema, especially in non-smokers or those with a family history of COPD. Screening for AAT levels is crucial in these populations to identify the underlying cause and guide specific management, such as augmentation therapy, which can slow disease progression.

COPD and metabolic syndrome frequently co-occur. Which component of metabolic syndrome directly worsens systemic inflammation and airflow limitation?

Answer: Central adiposity

Central adiposity promotes systemic and airway inflammation through adipokine release, which can worsen COPD severity and exacerbation frequency.

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.

The BODE Index is used in advanced COPD to predict:

Answer: Mortality risk and can identify patients who may benefit from palliative care referral

The BODE Index (Body mass index, airflow Obstruction, Dyspnea, Exercise capacity) predicts mortality in COPD and helps identify patients who warrant palliative care referral.

Electronic cigarettes (e-cigarettes) in COPD patients who are trying to quit smoking — what is the current US guideline position?

Answer: Not recommended as a cessation tool due to insufficient evidence and potential harm

US guidelines do not recommend e-cigarettes as cessation tools for COPD patients due to lack of long-term safety data and insufficient evidence of efficacy.

Which of the following medication classes is considered the cornerstone of pharmacological management for symptomatic COPD patients?

Answer: Bronchodilators

Bronchodilators are the central and foundational treatment for managing COPD symptoms. They work by relaxing the muscles around the airways, which helps to open them up and make breathing easier. This class includes both short-acting and long-acting beta-agonists and anticholinergics.

Which of the following is a recognized barrier to palliative care integration in COPD compared to cancer?

Answer: COPD has an unpredictable disease trajectory making prognostication difficult

The unpredictable, fluctuating course of COPD with acute exacerbations followed by partial recovery makes it difficult to identify a clear transition point for palliative care initiation.

The concept of 'total pain' in palliative care encompasses which of the following dimensions?

Answer: Physical, psychological, social, and spiritual suffering

Dame Cicely Saunders' concept of 'total pain' encompasses physical, psychological, social, and spiritual suffering, requiring a holistic interdisciplinary approach.

Which of the following best defines 'hospice eligibility' criteria for a COPD patient in the United States?

Answer: Prognosis of 6 months or less if disease follows its natural course, as certified by a physician

US Medicare hospice benefit requires a physician to certify a prognosis of 6 months or less if the illness runs its expected course.

Which cardiovascular comorbidity is most commonly associated with COPD and significantly increases mortality risk?

Answer: Ischemic heart disease

Ischemic heart disease is the most prevalent cardiovascular comorbidity in COPD patients and is a leading cause of death in this population.
