Peritonitis (Acute/Chronic) MCQ Quiz | Gastrointestinal System

Welcome to this comprehensive quiz on Peritonitis, a critical topic within the Gastrointestinal System for MBBS students. This quiz is designed to test your understanding of the pathophysiology, diagnosis, and management of both acute and chronic forms of peritoneal inflammation. Covering everything from Spontaneous Bacterial Peritonitis (SBP) in cirrhotic patients to secondary peritonitis from a perforated viscus, these 25 multiple-choice questions will challenge your clinical knowledge. After completing the quiz, submit your answers to receive your score and a detailed review of the correct responses. For your future reference and revision, you can also download all the questions along with their correct answers in a convenient PDF format. Good luck!
