Question

Quizplus · Accepted Answer

Dyspnea specifically refers to difficulty breathing or labored respiration due to lung disease. Cough (A) is a reflex action that expels mucus or irritants from the throat and lungs. Pneumonia (B) is an infection that can cause dyspnea, but the term itself does not refer exclusively to labored breathing. Expectoration (D) refers to the act of coughing up and spitting out mucus or phlegm from the respiratory tract, but it does not encompass the broader concept of difficult or painful respiration.
