a - heparin
b - lmwh such as enoxaparin or dalteparin
c- warfarin
d- danaparoid

Explain how heparin is produced

True or False:
The MW of unfractionated heparin is between about 12000-16000Da

True or False
Heparin is a heterogeneous mix of glycosaminoglycans of variable length

How does heparin work?

True or False:
To inactivate thrombin, heparin must form a ternary complex binding both AT and thrombin and only UFH with >18 saccharide units can do this

By what routes do we administer heparin?

Which of the following statements is incorrect?
a. heparin is extensively bound to plasma proteins

c. the half-life of UFH is independent of dose

How is heparin eliminated from body?

Does unfractionated heparin require close monitoring and periodic dose adjustment?

Explain how LMWHs differ from heparin (UFH) - how are they made and in chemical structure how do they differ?

What are two examples of LMWHS?

How is the anticoagulant effect of LMWHs produced and how does it differ from heparin (UFH)?

Can dalteparin and enoxaparin be interchanged clinically (i.e. swap patients between these two LMWHs)?

What are the advantages of LMWHs over heparin (UFH)

Is the anticoagulant effect of LMWHS fully reversed by protamine sulphate?

True or False:
LMWHs supplied in prefilled syringe must have the bubble in syringe expelled before use

True or False
The needles on the LMWH profiled syringes should be wiped with a swab before injection
