EMT Signs and Symptoms Practice Test

Left-sided heart failure best fits a gradual onset of dyspnea with a productive cough because fluid backs up from the left heart into the lungs, causing pulmonary edema. As pressures rise in the pulmonary capillaries, fluid accumulates in the alveoli, leading to shortness of breath and a cough that can bring up secretions. This process often develops over days rather than happening abruptly.

In contrast, acute pneumonia usually presents with fever and a more sudden onset of feverish symptoms and productive cough due to infection. Pleurisy tends to cause sharp chest pain that worsens with breathing rather than primarily a progressive cough and dyspnea. Right-sided heart failure typically shows signs of systemic congestion—like leg and abdominal swelling—rather than the pulmonary symptoms described.
