Choose an option:

Enoxaparin should be given to prevent potential thrombosis.

Enoxaparin should be given to treat acute disseminated intravascular coagulation in this patient.

Enoxaparin should be used to treat microvascular thrombosis.

Enoxaparin should not be given because it is contraindicated in patients with this level of thrombocytopenia.

No treatment is necessary given the lack of signs and symptoms of thrombosis.
