What are the signs and symptoms of pulmonary embolism?

Sudden unexplained dyspnea
Tachycardia, bradypnea
Bradycardia, hyperpnea
Hypertension, cyanosis

The correct answer is: Sudden unexplained dyspnea

Sudden unexplained dyspnea is indeed a classic sign of pulmonary embolism. This occurs when a blood clot blocks a pulmonary artery, leading to decreased blood flow to the lungs and resulting in shortness of breath. This symptom can appear very suddenly, which makes it particularly alarming and indicative of a potentially serious condition. In addition to dyspnea, patients may also experience other related symptoms such as chest pain, hemoptysis (coughing up blood), or rapid heart rate, but the abrupt onset of dyspnea is a primary feature. The other conditions mentioned in the available choices might relate to different issues rather than specifically identifying pulmonary embolism. For example, while tachycardia could be a response to various medical emergencies, it's not definitive on its own without the context of other symptoms, such as the sudden onset of difficulty breathing. Similarly, bradycardia and hyperpnea do not align with typical presentations of pulmonary embolism. Understanding the primary and most indicative symptoms helps in recognizing emergency situations effectively.
