Answer 1

1.  B is the correct answer.  Patients with their initial diagnosis of DVT need to be anti coagulated and have a goal INR of between 2.0-3.0 if coumadin is used.  They should be anti coagulated for 3-6 months.  Consider repeating the vascular study before discontinuing therapy.  The second DVT should be anti-coagulated for life and/or get a Greenfield filter.
