• D. Severe headache, muscle weakness, and dizziness

Answer: (C)

The common signs of a pulmonary embolism include sudden shortness of breath, chest pain, and cough. When a pulmonary embolism occurs, typically due to a blood clot that travels to the lungs from the legs or other parts of the body, the body reacts quickly to the blockage in the pulmonary arteries.

Sudden shortness of breath happens because the affected lung can't adequately exchange oxygen and carbon dioxide due to reduced blood flow. The chest pain associated with a pulmonary embolism can feel sharp or stabbing and may worsen upon deep breathing or coughing. A cough may also be present, and in some cases, it might produce blood-streaked sputum, indicating irritation in the lungs.

Recognizing these symptoms is critical for prompt diagnosis and treatment, which can significantly impact patient outcomes. Understanding this set of symptoms is essential in emergency medical services, as they directly indicate a life-threatening condition that requires immediate intervention.
