A common assessment finding in patients with pulmonary embolism is cyanosis. Cyanosis occurs due to inadequate oxygenation of the blood, which can happen when a pulmonary embolism obstructs blood flow in the lungs. This obstruction can lead to a decrease in blood flow to the areas of the lung responsible for oxygen exchange, resulting in lower oxygen levels in the bloodstream. Consequently, the skin, particularly around the mouth and extremities, may take on a bluish tint, indicating that tissues are not receiving enough oxygen.

In contrast, while hypertension and hypotension can occur in different clinical scenarios, they are not the hallmark signs of pulmonary embolism. Palpitations may be experienced due to anxiety, hypoxia, or other factors, but they are not as directly associated with the condition as cyanosis is. Understanding the physiological effects of a pulmonary embolism helps in recognizing its signs and symptoms effectively, leading to rapid diagnosis and intervention.
