Pulmonary embolism commonly presents with which symptom?

• A. Cough with mucus
• B. Hemoptysis
• C. Acute dyspnea
• D. Hypotension

Answer: (C)

Pulmonary embolism most often shows up as sudden shortness of breath. When a clot blocks part of the lung’s blood supply, the body’s air and blood flow become mismatched, which triggers rapid breathing and a sense of breathlessness. This symptom tends to be the most common and prominent early sign in many patients with PE, even before other findings appear. Other options can occur but are less consistent. Cough with mucus is not typical for PE and more commonly points to infections or bronchial disease. Coughing up blood can happen with PE, but it’s not as common as dyspnea. Hypotension can occur when a large embolus suddenly blocks blood flow (a massive PE), but many PEs are not initially associated with low blood pressure, so it’s less consistently seen than acute dyspnea.
