Answer and Explanation 3

3.  C is the correct answer.  This patient has a large left sided subarachnoid hemorrhage with a midline shift.  She needs her Coumadin reversed as soon as possible.  Protamine is the reversal agent for heparin not Coumadin.  Patients with subdural hematoma have the bleeding around the outside of the brain not in the parachemyma.  This patient does not have a visible brain mass on CT scan.  It is not uncommon for patients to bleed into the mass but they are usually more circumscribed and not so irregular.
