Great job! You correctly identified that the warfarin would make the subdural bleed worse. The neurosurgeon on the phone is really pleased that there is a junior doctor who has shown some initiative.

The patient was taken up to neurosurgery where a burr hole was performed (you star, you knew they needed one all along). They then were taken back to the ward.

One week later you receive a thank you card for your help in that stressful situation.

The delay with the unnecessary lumbar puncture faff was also not ideal.  Still, the patient lives, and so does your GMC number.

Final score: 5/10
