What is A 90-year-old woman with a fractured neck of femur is receiving low-molecular-weight heparin (LMWH). Which of the following statements regarding LMWH is true? and explain in detail?
Low molecular weight heparins (LMWH) are fragments of unfractionated standard heparin with mean molecular weights between 4000 and 64,000 d.

LMWH has greater bioavailability, more effective anticoagulant effect, lower incidence of heparin- associated thrombocytopenia, and can be administered once daily.
