MRCP2-0555

A 70-year-old man presents to the emergency department with a reduced level of consciousness after a recent fall and head injury. He has a past medical history of atrial fibrillation. His medications include apixaban and bisoprolol.

Upon examination, his Glasgow coma scale is 12/15 (E 3 V4 M5). There is evidence of an external head injury with bruising and laceration in the right occipital area.

An urgent CT head is arranged, which reveals a large right-sided subdural haematoma.

What medication should be administered in this situation?
