15.     Role-play 1. Candidate’s instructions will be e-mailed shortly before the tutorial.

 

16.     Labour ward scenario 1.

Candidate’s instructions.

You are the registrar on duty and responsible for the labour and gynae wards. You have just had the handover. Your task is to discuss the overall management of the wards with the examiner, to prioritise the patients and decide the allocation of staff to care for them.

This station was the first of its kind I used for the OSCE exam when it was introduced more than 25 years ago. There are phrases and concepts that reveal this distant origin, but I have retained them for nostalgic reasons. I ran the tutorial on a Sunday afternoon when I was on-call and used what was happening on the labour and gynae wards that day. You won’t be asked about gynae patients in a labour ward station!

Labour Ward. Sunday 13.00 hours.

17.     Viva. Topic will be revealed during the tutorial.

 

18.     Mycoplasma genitalium.

Many of the questions are not true EMQs as they have more than one correct answer. I have tried to include all the facts I think might feature in the exam and packing more than one into a question reduces the total number of questions and makes the document a bit more manageable. It also reduces the amount of typing I have to do.

NAAT:   nucleic acid amplification test.

NCSP:    National Chlamydia Screening Programme.

NHSCS: NHS Cervical Screening Programme
