What is a condition where the pulmonary arteries become blocked by a blood clot, leading to chest pain, shortness of breath, and other symptoms?
Correct Answer: A
Rationale: The correct answer is A: Pulmonary embolism. Pulmonary embolism occurs when a blood clot blocks one of the pulmonary arteries, leading to symptoms like chest pain and shortness of breath. This condition is a medical emergency as it can be life-threatening if not treated promptly.
B: Pneumothorax is the collapse of the lung due to air leaking into the chest cavity, not caused by a blood clot in the pulmonary arteries.
C: Pulmonary edema is the accumulation of fluid in the lungs, causing breathing difficulties, but it is not due to a blood clot in the pulmonary arteries.
D: Pulmonary hypertension is high blood pressure in the arteries of the lungs, not caused by a blockage from a blood clot.
