Which pharmacologic measure is used to dissolve the clot and maintain pulmonary circulation in pulmonary embolus management?

• A. Anticoagulation to dissolve clot and maintain pulmonary circulation
• B. Bronchodilators
• C. Corticosteroids
• D. Antihistamines

Answer: (A)

Dissolving the clot and restoring pulmonary blood flow in pulmonary embolism is accomplished with thrombolytic therapy, which directly breaks down the fibrin in clots to dissolve the embolus and reopen the pulmonary vessels. Anticoagulation, on the other hand, prevents new clot formation and stops the clot from growing, helping maintain circulation over time, but it does not actively dissolve an existing clot. The other drug classes listed (bronchodilators, corticosteroids, antihistamines) do not affect the embolus or pulmonary circulation in PE. Thrombolytic agents (for example, alteplase) are used when there is hemodynamic instability or massive PE to rapidly dissolve the clot and restore flow, keeping in mind the bleeding risk.
