In case of pulmonary embolism, right ventricle hypokinesia, and decreased output, which drug therapy is most helpful? 
Select and explain. 
A. Thrombolytic, B. LMW heparin, C. Warfarin, D. Heparin
A: Thrombolytic
Answer: A: Thrombolytic 
Explanation: Anticoagulation with Heparin has long been the standard treatment for normotensive patients with pulmonary embolism. By preventing clot propagation, heparin allows endogenous fibrinolysis to occur, with eventual resolution of thrombo-emboli. However in the absence of an absolute contraindication, patients with pulmonary embolism-induced hypotension or shock are usually treated with thrombolytic agents. The three thrombolytic agents used in treatment of pulmonary embolism are streptokinase, urokinase and recombinant tissue-type plasminogen activator(-PA).
