Coagulation
Click on the correct answer.
Not factor VIII, but increases factor VIII activity in patients with mild hemophilia A:
- cryoprecipitate
- tranexamic acid
- desmopressin acetate
- urokinase
- aspirin
Complex of purified human plasminogen and bacterial streptokinase
- alteplase
- reteplase
- anistreplase
- dicumarol
- protamine sulfate
Most likely to preferentially activate plasminogen bound to fibrin
- streptokinase
- alteplase
- urokinase
- anistreplase
- all the above
Clinical indications for fibrinolytic drugs:
- some acute myocardial infarctions
- ascending thrombophlebitis (iliofemoral vein)
- some cases of multiple pulmonary emboli
- A & B
- A, B & C
Increases prothrombin time:
- high-dose aspirin
- phenobarbital
- cholestyramine
- rifampin
- all of the above
Bleeding from warfarin may be reversed by:
- vitamin K
- factor I concentrate
- both
- neither
Aspirin irreversibly inhibits this enzyme, preventing thromboxane A2 synthesis.
- adenylyl cyclase
- guanylyl cyclase
- adenosine deaminase
- cyclooxygenase
- streptokinase
Approved for prevention of the venous thrombosis after hip replacement surgery:
- dalteparin
- danaproid
- enoxaparin
- all of the above
Generated within the platelet -- interacts with membrane receptors:
- collagen
- thrombin
- thromboxane A2
- ADP
- all of the above
Blocks GPIIb/IIIa platelet receptors:
- thromboxane A2
- aspirin
- abciximab
- ADP
- streptokinase
