159 free Medical trivia questions with answers — science & nature quiz, new questions added Aug 2026.
This medical trivia quiz covers the practice of medicine as most people meet it: the diseases and what causes them, the drugs in the cabinet, the specialties on the hospital directory, the gadgets doctors use, the great institutions and charities, and the Greek and Latin behind the words. The easy questions are ones anyone who has been to a GP can answer: which snake-and-staff symbol is the correct one, what the Rx on a prescription means, what a placebo is and which vitamin scurvy lacks. From there it gets harder: Sertürner naming morphine after the god of dreams, warfarin's start as rat poison, Viagra's origins as an angina drug, Botox as the deadliest natural substance, the 100-day cough, the disease of kings, Landsteiner's A/B/C, Riva-Rocci's cuff, the first implanted pacemaker in Solna, the Apgar and Glasgow scores, the ICRC's three Nobel Prizes, MSF and Biafra, the NHS's launch at Park Hospital, and why the caduceus is the wrong symbol. If you want the great discoveries and their discoverers, our Medical History quiz covers Jenner to Barnard; for anatomy, try our Human Body quiz. Every answer was checked against the encyclopaedia entries for the diseases, drugs, devices, specialties and organisations named before publishing, and the supporting sentence is stored with each question.
