He can begin to ambulate (according to the APTA): ● Don’t recommend bed rest following diagnosis of acute DVT after the initiation of anticoagulation therapy, unless significant medical concerns are present ● He can continue to ambulate because anticoagulation therapy has been in effect for at least 24 hrs, and she does not have signs of an active pulmonary embolism.
