First of all, BREATHE!!! Try to keep as calm as possible. Read the task in each station carefully before you act. OSCEs are always a bit scary but it is probably stuff you have done before in clinic. I'm not sure which uni you are at, but I expect they are all pretty similar in content. I can't remember exactly what the first year one involves as I'm quite an old woman now
but I will try and give you a few pointers and hope that someone blessed with a better memory or more recent experience can pitch in too. The best plan is probably to try and talk to some of the 2nd or 3rd year students who have all been through it more recently and also to your tutor, who may well give you some helpful pointers.
I'm struggling to remember all the stations I did but I can recall these:
A vascular assessment - probably locating pedal pulses and/or doppler use
A neuro assessment - probably demonstrating monofilament use
Perhaps a BNF task - perhaps looking up interactions
Maybe talking through the steps of CPR
Try to read back over your notes on any practical tests/assessments that you have been taught over the year (which may also crop up in your "Clinical Examination" exam too?). You'll be surprised how quickly the time passes in each station so make the most of your time. The examiner is not there to catch you out, just to observe your technique. They may ask you a few questions relating to the task in hand, but usually it's more of a demonstration that they want you to give.
Anyone else help any further?.....
PS - I would think that one of the 10 stations is likely to be a "rest" station where you can collect your thoughts for 5 mins. Pretty sure we always had one of those.
