This chapter is a question and answer style article that contains past FRCA paper examples related to neurosurgery, neuroradiology and neurocritical care. It also guides trainees on the most effective manner in which to approach these questions. The discussion covers the following: the cerebral physiological benefits of induced hypothermia following successful resuscitation from cardiac arrest (25%); how can a patient be cooled in these circumstances (20%); adverse effects that may occur due to the use of induced hypothermia (35%); and other nonsurgical clinical scenarios may the use of induced hypothermia be beneficial (20%).
