This book is highly interactive and the content has been so designed as to cover the syllabus of critical care medicine courses. This book has 32 chapters and approximately 950+ MCQs related to critical care medicine. The focus of MCQs is on problems that would be encountered commonly in clinical practice rather than an assessment of the anyone's knowledge of trivial facts that are seldom encountered. Majority of questions are prepared with the clinical case scenario followed by relevant signs, symptoms, subsequent findings, etc. In essence, all the relevant information is available that is necessary for a competent candidate to answer the question. Well-constructed MCQs will test the application of medical knowledge (context-rich) rather than just the recall of information (context-free). Ambiguity and the use of imprecise terms have been avoided throughout book.
