30 Diseases & Medicine trivia questions
Q1. A messy 1928 lab bench led Alexander Fleming to discover which life-saving mold-derived substance?
Answer: Penicillin
💡 Fleming noticed a mold called Penicillium had killed off bacteria in a forgotten petri dish — the first modern antibiotic.
Q2. Name the body's first line of defense — the system reacting the same way to any invader.
Answer: Innate immune system
💡 It includes physical barriers like skin and mucus, plus cells like macrophages that attack anything foreign.
Q3. What did Wilhelm Röntgen name the new 1895 ray that could see straight through skin to bone?
Answer: X-ray
💡 Röntgen refused to patent his discovery, believing it should benefit everyone, and won the first-ever Nobel Prize in Physics for it.
Q4. Medical graduates still invoke which ancient Greek physician reciting an oath to 'do no harm'?
Answer: Hippocrates
💡 He taught that illness had natural causes, not divine punishment — a radical idea in 5th-century-BC Greece.
Q5. Which Crimean War nurse used charts to prove disease killed more soldiers than battle wounds?
Answer: Florence Nightingale
💡 In 1858 she became the first woman elected to the Royal Statistical Society for her pioneering data visualizations.
Q6. Antibiotics are specifically designed to fight infections caused by which type of pathogen?
Answer: Bacteria
💡 That's why antibiotics do nothing against colds or flu, which are caused by viruses.
Q7. How many basic blood types make up the ABO blood-typing system?
Answer: 4
💡 They're defined by which sugar molecules, if any, sit on the surface of red blood cells.
Q8. In 1796, Edward Jenner protected a boy from smallpox using material from which cattle disease?
Answer: Cowpox
💡 The word 'vaccine' comes from 'vacca,' Latin for cow — a nod to Jenner's cowpox experiment.
Q9. The word 'vaccine' comes from the Latin word for which farm animal, via Edward Jenner's experiments?
Answer: Cow
💡 Jenner named his treatise 'Variolae vaccinae,' literally 'smallpox of the cow.'
Q10. In 1816, a French doctor rolled paper into a tube rather than press an ear to a patient — what?
Answer: The stethoscope
💡 René Laennec's paper tube let him hear heart and lung sounds more clearly than ever before, without direct contact.
Q11. When enough of a population is immune, indirectly shielding the rest, it's called what?
Answer: Herd immunity
💡 The exact vaccination threshold needed to reach it varies by how contagious a disease is.
Q12. Which blood type is nicknamed the 'universal donor' for near-universal transfusion use?
Answer: O-negative
💡 Only about 7% of people have this blood type, yet hospitals lean on it heavily in emergencies.
Q13. Raising your body temperature during a fever mainly helps do what to invading germs?
Answer: Slow down their growth
💡 Many pathogens reproduce best at your normal body temperature, so extra heat sets them back.
Q14. Which chronic lung condition is marked by inflamed, narrowed airways that make breathing hard?
Answer: Asthma
💡 Common triggers include allergens, exercise, cold air, and respiratory infections.
Q15. Which specialist doctor focuses on diagnosing and treating the heart?
Answer: Cardiologist
💡 The name comes from the Greek kardia, meaning heart; a nephrologist by contrast handles the kidneys.
Q16. Which French scientist proved invisible microorganisms cause disease, now called germ theory?
Answer: Louis Pasteur
💡 Pasteur also developed the first rabies vaccine, successfully treating a boy bitten by a rabid dog in 1885.
Q17. Which type of blood cell produces antibodies to help fight off germs the body has met before?
Answer: B cells
💡 B cells are part of the adaptive immune system, which builds a 'memory' of past infections.
Q18. In 1854, a London doctor traced a deadly cholera outbreak to which single contaminated source?
Answer: A water pump
💡 John Snow mapped the cholera deaths and convinced officials to remove the handle from the Broad Street pump, and the outbreak quickly faded.
Q19. Which rat-flea-borne bacterium wiped out about a third of Europe in the 1300s?
Answer: Yersinia pestis
💡 This outbreak became known as the Black Death, and the same bacterium still causes rare plague cases today.
Q20. In 1846, which gas did a Boston dentist use for the first public surgical anesthetic demo?
Answer: Ether
💡 The event is still commemorated every October — the operating theater is nicknamed the Ether Dome to this day.
Q21. In 1867, which British surgeon sprayed carbolic acid on wounds, founding antiseptic surgery?
Answer: Joseph Lister
💡 At his hospital, surgical mortality on one ward fell from 45% to 15% within a few years of adopting the technique.
Q22. Unlike antibiotics, antiviral drugs typically fight infection by doing what inside cells?
Answer: Blocking the virus from replicating
💡 Because viruses hijack a host's own cellular machinery, treating them takes a different approach.
Q23. In 1847 Vienna, Ignaz Semmelweis slashed deadly childbed fever rates by insisting doctors do what?
Answer: Wash their hands
💡 His rule cut mortality on his ward from about 18% to under 2%, yet doctors mocked him for it.
Q24. Which blood type is nicknamed the 'universal recipient,' able to accept nearly any donation?
Answer: AB-positive
💡 People with this type carry both A and B antigens, so their immune system won't reject either.
Q25. The '+' or '-' symbol after a blood type refers to the presence of which surface protein?
Answer: Rh factor
💡 The name comes from rhesus monkeys, used in the original 1940s experiments that identified it.
Q26. Which type of white blood cell usually arrives first to fight off a new infection?
Answer: Neutrophils
💡 They make up 60-70% of your circulating white blood cells and die off quickly after the fight.
Q27. Unlike Type 2, Type 1 diabetes happens when the immune system attacks cells that make what?
Answer: Insulin
💡 Type 1 usually appears earlier in life and always requires insulin treatment to manage.
Q28. Because it's split into parts, one blood donation can typically help how many patients?
Answer: Up to three
💡 Red cells, platelets, and plasma each get separated out to treat different medical needs.
Q29. Ronald Ross dissected mosquitoes in 1897 to prove they carry the parasite behind which disease?
Answer: Malaria
💡 Ross traced the malaria parasite's life cycle inside Anopheles mosquitoes and won the Nobel Prize for it in 1902.
Q30. In 1882, Robert Koch identified the bacterium behind which disease, then killing 1 in 7 worldwide?
Answer: Tuberculosis
💡 Koch's rigorous method for linking a specific germ to a specific disease became known as Koch's postulates, still used today.
