What is the primary concern associated with a pulmonary embolism (PE)?

• A. Reduced blood flow to the heart
• B. Increases in blood pressure
• C. Blockage in the lung arteries
• D. Fluid accumulation in the abdomen

Answer: (C)

The primary concern associated with a pulmonary embolism (PE) is a blockage in the lung arteries. When a blood clot travels from another part of the body—most commonly from the legs, known as deep vein thrombosis—and lodges in the pulmonary arteries, it obstructs blood flow to the lung tissue. This can result in severe complications, including reduced oxygenation of the blood, impaired lung function, and can lead to respiratory failure. The blockage can also set off a cascade of responses in the body that may lead to cardiovascular collapse and death if not promptly treated. Other options, while they may relate to the complexities and consequences of a PE, do not address the immediate and most critical issue at hand, which is the obstruction in the lung's arteries causing a potential lack of oxygen supply to the body. This blockage is directly responsible for the life-threatening nature of a pulmonary embolism.
