The Christmas Themed Medical Quiz Every Doctor Should Try

'Tis the season to test your medical knowledge! Whether you're a junior doctor sneaking a break between ward rounds or a seasoned clinician looking for some festive fun, a christmas themed medical quiz might be exactly what you need to spice up your holiday season.

Medical trivia has always been a brilliant way to keep your clinical knowledge sharp, but add a Christmas twist and suddenly it becomes something even more memorable. From conditions that spike during the winter months to the surprisingly medical history behind some of our favorite holiday traditions, there's far more festive medicine out there than you might expect.

In this quiz-style listicle, you'll encounter questions that blend seasonal themes with genuine clinical knowledge. Some will make you chuckle, others will genuinely challenge you, and a few might even teach you something new to impress your colleagues at the Christmas party. Each question comes with a detailed explanation so you're not just testing yourself, you're actually learning along the way. So grab a mince pie, settle in, and let's see how well your medical brain performs under a little holiday pressure.

Why Medics Take Their Christmas Quizzes Seriously

Let's be honest: medics do not do anything casually, including Christmas quizzes. There is a reason the BMJ Christmas edition has run every year since 1982, accumulating well over 1,000 peer-reviewed articles on topics ranging from the thermodynamics of fondue to a longitudinal cohort study tracking teaspoon disappearance in communal kitchens. These are not spoofs. They go through full peer review. They are just gloriously, unapologetically niche, and only a medically literate audience truly appreciates why that matters. Groups like KingstonGasDocs built an entire annual Christmas Journal Club Quiz around the BMJ edition, because when your colleagues have read the same literature, the in-jokes land differently.

Medicine is also, perhaps surprisingly, saturated with Christmas references embedded directly in the clinical literature. A PubMed search returns 307 papers written by authors with the surname Christmas alone, which tells you everything you need to know. Christmas disease, Christmas tree bladder, pityriasis rosea with its Christmas tree distribution: the festive canon runs deeper than most registrars realise until someone asks them about it under mild social pressure at a departmental do.

That departmental do matters, too. NHS organisations including NHS Tayside's Health and Work Team publish downloadable Christmas quizzes explicitly framed as tools to build team spirit and boost morale, which gives this format genuine institutional legitimacy rather than pub-quiz novelty.

This post is built for NHS departments, junior doctor common rooms, and medical school socials. Whether you are procrastinating between ward rounds or planning a Christmas rota gathering, consider this your specialist resource.

Round 1: Conditions Named After Christmas (5 Questions)

Right then, let's get into the festive medicine. This first round is deceptively straightforward on the surface, but it will sort the room quickly. These are conditions and clinical findings that literally carry Christmas in their name, and yet a surprising number of clinicians would stumble on at least two of them. Pour yourself something warm and see how you get on.

Q1: What is Christmas Disease?

Answer: Haemophilia B, a clotting factor IX deficiency.

This is your opener and your filter question. Christmas disease is named after Stephen Christmas, a five-year-old boy who became the first described patient in the landmark 1952 Biggs et al. paper published in the BMJ on 1 December of that year. The paper identified seven patients with a non-classical haemophilia caused by deficiency of a previously unrecognised clotting factor, distinct from anti-haemophilic globulin, which the team named the Christmas factor. We now call it Factor IX. Biggs herself described "Christmas Disease" as a "legitimate, unassuming, and pleasantly provocative term," which frankly is a standard we should all aspire to in naming things. Anyone who sat through haematology and still answers "haemophilia A" here has questions to answer. Full marks require knowing it is haemophilia B, and knowing why.

Q2: What is Christmas Tree Bladder?

Answer: A cystoscopic and radiological appearance associated with severe neurogenic bladder or interstitial cystitis.

This one is niche enough that getting it right feels genuinely earned. The Christmas tree bladder describes a pointed, irregular bladder outline, where the appearance on imaging or cystoscopy resembles the silhouette of a fir tree. In the context of interstitial cystitis and bladder pain syndrome, mucosal haemorrhages scattered across the bladder wall have also been likened to the lights on a Christmas tree. Urology colleagues will get this immediately; most others will not, and that is entirely the point of including it.

Q3: Which Rash Has a Christmas Tree Distribution?

Answer: Pityriasis rosea.

A genuine dermatology favourite and a reliable differentiator at medical student level. The herald patch appears first, a single larger oval lesion, followed over days to weeks by smaller satellite lesions that spread along the lines of skin cleavage on the trunk. Viewed from behind, the pattern traces the outline of a fir tree. Every student learns this, most forget it by the time it matters clinically, and it has the dual pleasure of being both visually memorable and genuinely useful in practice.

Q4: What is Christmas Eye?

Answer: A colloquial term for epidemic keratoconjunctivitis, an adenoviral ocular infection with winter seasonality.

It is worth noting here that some sources describe "Christmas eye" as referring to a distinct Australian presentation caused by beetle toxins rather than adenovirus, so regional variation in usage does exist. For the purposes of a UK clinical quiz, the epidemic keratoconjunctivitis framing is the more commonly taught association, characterised by follicular conjunctivitis, corneal involvement, and a tendency to circulate during the winter months. Either way, it is an underappreciated festive eponym.

Q5: What Christmas-Related Term Describes Festive Mood Deterioration?

Answer: Christmas depression.

This is the question with the most clinical weight. Christmas depression refers to the specific worsening of depressive symptoms that occurs in patients around the festive period, driven by social isolation, family conflict, financial strain, and disrupted routines. It is distinct from seasonal affective disorder, which is primarily driven by reduced light exposure across the autumn and winter as a whole. Christmas depression has a more targeted trigger, and it is significantly underrecognised in primary and secondary care. Asking this in a quiz is a quiet reminder that the festive period is not universally joyful for our patients, and that awareness matters clinically.

Round 2: Festive Clinical Trivia (5 Questions)

Right, Round 2. This is where we separate the consultants who actually read the Christmas BMJ from those who just flipped to the cartoons. These five questions lean into clinical knowledge with a seasonal twist, so expect a few heated debates across the table.

Question 6: Which bedside test for Myasthenia Gravis involves applying something cold to the eyelid, and what is the cold item used?

The answer is the ice pack test, and the cold item is exactly what it sounds like: a bag of ice applied directly to the ptotic eyelid for two minutes. If you happen to be working a December shift and find yourself outdoors, a snowball is technically also valid, which is the kind of clinical flexibility the exam boards never quite prepare you for. The mechanism is elegantly simple. MG symptoms worsen with heat because acetylcholinesterase activity increases at the neuromuscular junction, degrading acetylcholine faster and worsening transmission failure. Cold suppresses that enzymatic activity, temporarily improving ptosis by at least 2mm in a positive result. What makes this genuinely impressive as a bedside test is the diagnostic accuracy; the ice pack test carries a pooled sensitivity of 0.94 and specificity of 0.97, placing it among the most reliable non-invasive tests in neurology. Compare that to the edrophonium test, which requires atropine on standby and carries a real risk of cholinergic crisis, and you start to appreciate why the ice pack approach has endured. Cheap, painless, bedside-ready, and genuinely diagnostic; it ticks every box.

Question 7: Which genetic condition produces "elf-like facies" and is therefore possibly the most Christmas-adjacent diagnosis in medicine?

Williams Syndrome, and yes, the term "elfin facies" appears in the peer-reviewed literature without a hint of irony. The characteristic features include periorbital fullness, a broad forehead, upturned nose, wide mouth, and full lips, alongside a notably gregarious and overly friendly personality profile that has also been formally documented. The condition results from a deletion on chromosome 7q11.23 and affects approximately 1 in 7,500 to 10,000 live births. Clinically, it is associated with supravalvular aortic stenosis in around 70% of cases, renal artery stenosis, and idiopathic hypercalcaemia, so the elfin presentation has some serious cardiology attached to it. LITFL's Christmas edition quiz framed this beautifully for exactly this kind of festive trivia context.

Question 8: What is Holiday Heart Syndrome?

This one is a gift for any doctor who has worked a December A&E shift. Holiday Heart Syndrome refers to atrial fibrillation precipitated by acute alcohol consumption in individuals with no pre-existing structural heart disease. First described by Philip Ettinger in 1978, it clusters predictably around Christmas and New Year. Large population data published in Circulation found that more people in the United States die of cardiac causes on 25 December than on any other day of the year, with 26 December and 1 January close behind. The American Heart Association has continued flagging this syndrome as recently as December 2025. Worth knowing, worth sharing with your patients, and absolutely worth five quiz points.

Question 9: In which year did the BMJ first publish a dedicated Christmas edition?

The answer is 1981, and this is the question that genuinely stumps even very senior colleagues. Most people assume the tradition is older, given how embedded the BMJ Christmas edition has become as a cultural fixture. Since 1981 it has published the faux-trials, comic case reports, and statistically sound nonsense that the medical community quietly loves. Incidentally, the BMJ's festive relationship with medicine goes back further; Christmas disease was first reported in the BMJ's Christmas issue all the way back in 1952, so the journal had form long before the dedicated edition launched.

Question 10: Which neurotransmitter pathway is most directly implicated in the pathophysiology of Seasonal Affective Disorder?

The serotonergic pathway. Reduced exposure to natural light suppresses serotonin synthesis and simultaneously increases melatonin secretion from the pineal gland, disrupting circadian rhythm. The result is the characteristic presentation of the winter subtype: low mood, hypersomnia, and notable carbohydrate craving. It is a question that rewards both the psychiatry trainees and anyone who has genuinely struggled through a British January, which in this room is probably everyone.

Round 3: Medical Christmas Pub Quiz Wildcards (5 Questions)

Welcome to the wildcard round. This is where the questions stop being predictable and start being the kind of thing that makes your colleagues stare into the middle distance. Five questions, all medically grounded, all designed to reward lateral thinking over rote recall. Set your teams up for a productive argument.

Question 11: PubMed returns 307 papers authored by someone with the surname Christmas. True or false, and which medical specialty accounts for the highest concentration of these papers?

Answer: True. The majority cluster in haematology, which should surprise nobody familiar with the legacy of Factor IX deficiency (Christmas disease). The condition was named after Stephen Christmas, a young British boy first diagnosed in 1952 after nine hospitalisations and a landmark BMJ paper. Haemophilia B affects approximately 1 in 19,200 male births in the US according to CDC data, making it far less common than Haemophilia A, which is roughly seven times more prevalent. The surname has been leaving its mark on the haematology literature ever since. Deploy this fact at your next departmental quiz and watch the registrars quietly respect you.

Question 12: Which major NHS event predictably spikes every December and is now so well-documented it has its own operational planning category?

Answer: The winter surge. This is not technically named after Christmas, but every NHS clinician will recognise it from lived experience. It is a convergence of increased respiratory illness (RSV, influenza, COVID-19), hypothermia presentations, a spike in alcohol-related admissions that ties neatly back to Holiday Heart Syndrome from Round 2, and significantly reduced community care capacity across the Christmas period. NHS trusts plan for it annually with dedicated operational frameworks. If anyone in your quiz team has not experienced a chaotic Christmas Day on the wards, they are either very junior or very lucky.

Question 13: A patient presents with tingling in the fingers and toes, fatigue, and a lemon-yellow tinge to their skin after Christmas dinner. Most likely diagnosis?

Answer: Subacute combined degeneration of the spinal cord, secondary to B12 deficiency. The lemon-yellow colour is the clinical giveaway; it reflects a combination of pallor from anaemia and mild jaundice from haemolysis. The Christmas dinner framing is a deliberate red herring. This is a chronic, insidious presentation that has nothing to do with what the patient ate on 25 December. It is classic exam-style misdirection, and it catches out anyone who starts thinking about food poisoning or overindulgence rather than the neurology.

Question 14: Which antimicrobial was nicknamed the Christmas tree antibiotic in some early prescribing cultures due to the appearance of its molecular structure?

Answer: Trimethoprim is occasionally referenced informally in this way, though no single antibiotic holds this title with any authority. That is precisely what makes it a good wildcard. Throw it into the room and you will immediately identify everyone who actually enjoyed pharmacology. The more useful clinical point is trimethoprim's role as a dihydrofolate reductase inhibitor with a diaminopyrimidine structure that does have some branching characteristics. Treat this one as a conversation starter rather than a citable fact, and be upfront with your teams that the debate is the point.

Question 15: You are the registrar on call on Christmas Day. A nurse bleeps you to say a patient's observations chart looks festive, red and green lights across the board. What is the most likely clinical scenario, and what is your first priority?

Answer: The patient is almost certainly hypoxic, with a concurrent fever triggering two separate red flag alerts, while heart rate and blood pressure remain within normal limits (the green lights). First priority is a clinical review using an ABCDE approach. This question is not testing festive knowledge at all; it is testing situational judgement and clinical prioritisation under pressure. It also reflects something that genuinely happens on Christmas Night shifts, where you have to translate a nurse's colloquial description into a clinical picture fast. The best teams will answer this one without hesitation. The rest will pause and overthink the Christmas theme, which is entirely the intention.

How Did You Score?

Right then. Add up your scores and find yourself below.

0 to 5 correct: Still on the pre-clinical attachments, are we? Nothing to worry about — Christmas disease will stick after this.

6 to 10 correct: Solid foundation, consultant-in-training energy. You knew pityriasis rosea and that is what counts.

11 to 14 correct: Registrar-level festive excellence. Your department is lucky to have you on the Christmas rota.

15/15 correct: Suspiciously good. Either you wrote this quiz or you have genuinely read the 1952 Christmas disease paper on a Friday night. We respect it.

Now, the obvious next step: screenshot your result and drop it in the on-call group chat or your medical school cohort. Consider it the medical alternative to a Christmas cracker joke, except this one actually requires a functioning brain to answer. Your colleagues will either be impressed or quietly mortified, and both outcomes are equally entertaining.

If you did get the full fifteen, the real prize is knowing you will absolutely clean up at the departmental Christmas quiz. That impresses precisely nobody except other doctors, which is, honestly, the correct audience.

Now over to you. Drop a comment below with which question caught you out, which one felt too straightforward, and what Christmas medical trivia you think deserved a place on this list. We are always taking suggestions for the next round.

Stumped on What to Get Your Medic Friend This Christmas?

If this quiz has demonstrated anything, it is that doctors occupy a very specific cultural world, and buying gifts for them requires the same level of precision they apply to a differential diagnosis. Generic will not cut it. Another novelty stethoscope keyring purchased in a hurry says "I know you work in medicine" without saying anything else. Medical-themed gifts designed by someone who actually lives inside that culture land on a completely different level.

That is exactly the thinking behind Clerked, a small apparel and publication brand designed by an NHS consultant. The range covers original medical-themed tees, hoodies, sweatshirts, mugs, tote bags, and accessories, all made with soft cotton and removable tags for comfort. Because off-duty doctors have earned the right to wear something that does not irritate them after a twelve-hour shift.

Free UK shipping is included as standard, and every purchase contributes to charitable causes at no extra cost. Which means you get to feel quietly excellent about buying someone a genuinely funny medical hoodie.

Whether you are shopping for a medical student who just survived their first Christmas on call, a registrar who aced every round of this quiz, or an FY1 who simply needs something to make January feel survivable, the Clerked gift range is worth a proper look before you default to something forgettable.

The Medical Christmas Quiz Tradition Is Worth Keeping

The tradition of the Christmas medical quiz is not trivial. From the BMJ's annual Christmas edition, which has applied rigorous methodology to gloriously absurd questions for decades, through to NHS departmental quiz nights and on-call group chat banter, this format exists for a reason. Medicine is a genuinely demanding profession, and shared laughter, collective knowledge, and a bit of festive absurdity are not frivolous extras; they are part of what keeps teams functional and human. The New York Times recognised the BMJ Christmas tradition as lighthearted but rigorous scholarship, which is precisely the spirit a good medical quiz should carry.

So bookmark this one. Send it to your on-call group chat, use it to open your departmental Christmas do, or simply use it to confirm that you retained something from that haematology lecture in second year. If you picked up something new along the way, whether that was the ice pack test sensitivity, the existence of Christmas tree bladder, or the very real phenomenon of Holiday Heart Syndrome, then this quiz did exactly what it was supposed to do.

Come back next year. The BMJ will publish another Christmas edition, the winter surge will arrive on schedule, and there will be another cohort of medics who deserve a proper quiz to mark the occasion.

Conclusion

A Christmas themed medical quiz is more than just holiday entertainment. It is a genuinely effective way to reinforce clinical knowledge, discover fascinating seasonal medicine, and share a few laughs with colleagues during one of the busiest times of the year.

The key takeaways here are simple: festive learning sticks better than dry revision, winter medicine has more depth than most clinicians realise, and even a short quiz can sharpen skills you use every single day.

So do not let the holiday rush become an excuse to switch your brain off entirely. Share this quiz with your team, challenge a colleague over coffee, or tackle it solo between shifts. The best clinicians never stop learning, even in December. Give it a go and see how your festive medical knowledge truly measures up.
