This is the first dedicated revision aid for the Single Best Answer component of the Final FFICM, added to the written examination in July 2014. It contains 240 SBA practice questions, divided into eight papers covering the Faculty of Intensive Care Medicine curriculum. Each answer consists of a short explanation, allowing a quick review of the correct answer, and a long explanation, providing a more in-depth discussion of the question topic. All answers are also fully referenced, encouraging further reading and providing sources for more detailed study. In combination with the companion volume, Multiple True False Questions for the Final FFICM, this guide allows readers to access full written mock exams in the style and format of the official FFICM examination, and is an invaluable resource for trainees in intensive care medicine.
