Patients with COPD often get progressively worse and call an ambulance because of:
A
Loss of appetite
B
Development of a skin rash
C
Acute exacerbation of shortness of breath (dyspnea)
D
Sudden onset of joint pain
Verified step by step guidance1
Understand the context of the problem: COPD (Chronic Obstructive Pulmonary Disease) is a chronic respiratory condition that affects airflow and breathing. Patients with COPD often experience worsening symptoms over time.
Identify the key symptom in the question: The problem asks about a common reason why patients with COPD call an ambulance. The options provided include symptoms unrelated to COPD (e.g., loss of appetite, skin rash, joint pain) and one directly related to respiratory distress (acute exacerbation of shortness of breath).
Recall the hallmark symptoms of COPD: COPD is characterized by chronic symptoms such as shortness of breath (dyspnea), chronic cough, and sputum production. Acute exacerbations often involve a sudden worsening of these symptoms, particularly shortness of breath.
Eliminate incorrect options: Loss of appetite, skin rash, and joint pain are not typical symptoms of COPD or reasons for calling an ambulance. These symptoms are more likely associated with other conditions.
Conclude that the correct answer is 'Acute exacerbation of shortness of breath (dyspnea)' because it aligns with the primary respiratory issues experienced by COPD patients during an emergency.
