For the actor

You are 25 and called Michael Jones. You started to notice that your stools were more runny than normal two weeks ago, and since then you have been opening your bowels with increasing frequency up to 10 times per day. This is very unusual for you. For the last five days you have noticed blood in the stool, and this morning the toilet pan was filled with blood, which alarmed you and made you come to the emergency department. You have no other previous visits to doctors or the hospital. You are not short of breath. If asked, say that you have felt more tired than usual recently. No nausea or vomiting and no shortness of breath. If asked about pain, say that you have had one or two twinges of pain in your stomach during attacks of the diarrhoea but otherwise not.

You drink 5 pints of beer most Saturday nights, do not smoke and have no allergies. You have two sisters who are both healthy and your parents are both healthy and in their 50s. Your appetite is usually good but you have been less hungry than normal for the past two weeks. Your jeans are looser than normal. You have had no recent overseas travel.

For the examiner

Agree, Kirstin. I think they will make it more complicated like diarrhoea +_ Jaundice in a returned traveller. The kicker is you have to actively listen out for the clue, e.g. "when i got back", if you don't explore travel history, sexual history, drug history than unlikely to pass...

Probably a little simple for a exit exam.
