A patient has heparin-induced thrombocytopenia (HIT). Which condition is a priority to assess?

Explanation:
HIT creates a prothrombotic state where antibodies activate platelets, leading to new clot formation even as the platelet count falls. The most urgent complication to assess is a pulmonary embolism because a clot that travels to the lungs can rapidly impair oxygenation and circulation, potentially causing sudden deterioration or death. Clinically, watch for acute shortness of breath, chest pain, tachycardia, or hypoxemia, and pursue urgent imaging to evaluate for PE. While a deep vein thrombosis can be the source of such emboli, the immediate priority is identifying and addressing a possible pulmonary embolism due to its life-threatening potential.
