Year 2 OSCE, JUNE 2017

Station 1 – Antibiotic Sensitivity

  • Aseptic technique of spreading culture on plate
  • Place 3 discs of antibiotic on plate
  • Measure zones of inhibition and fill out sheet interpreting antibiotic sensitivity

Station 2 – Inhaler Technique

  • Demonstrate proper inhaler and spacer technique to a simulated patient

Station 3 – CNS Anatomy

  • Where does spinothalamic tract decussate?
  • Point to falx cerebrii, thalamus, internal capsule
  • Which muscles are involved in accommodation reflex?
  • Where would you make incision to drain middle ear? Why?
  • Bones that form the pterion? Which artery runs deep to pterion?
  • Where do blood vessels that supply the brain lie?
  • Point to lamina on spine? Which spinal vertebrae is this?
  • Point to cranial nerves on model of brainstem
  • Point to and name foramen that cranial nerve V passes through

Station 4 – Renal Clearance

  • Make standards from 3 known concentrations (3:1 ratio with Ferric Nitrate)
  • Measure absorbance in Spectrophotometer (blank using diluent)
  • Two unknown patient samples – Add ferric nitrate in same ratio and measure absorbance
  • Given a standard curve to read off concentration of drug

Station 5 – Respiratory Exam

Station 6 – Lower Limb Motor Exam

  • Some students were asked to name all myotomes tested

Station 7 – Prothrombin Time

  • Not given much information in station and not prompted to move onto next part
  • Make sure to warm plasma and thromboplastin in water bath for 1 minute
  • Start timer when mixed and check every 15 seconds – seemed to be a wide variety of times between students
  • Given the PT of somebody taking warfarin and also the ISI of thromboplastin you used. Work out the INR of this patient (not given equation!)
  • Use answer to comment on dosage of warfarin and if it is appropriate (I believe it was too high?)
  • Finally comment on if you would expect any change in PT if patient had Liver Failure or Glanzmanns Thrombocytopaenia

Station 8 – Patient History (Stroke)

  • Neuro history of patient who is visiting GP following TIA the night before

Station 9 – Lower Limb Anatomy

  • Name one structure that appears superior and one structure that appears inferior to the piriformis
  • Point to gluteus medius, gracilis (plus innervation and nerve root), sciatic nerve, tibial tuberosity, tibialis anterior (and role), Navicular bone
  • Name borders of femoral triangle and contents medial to lateral
  • Which muscles form the calcaneal tendon?
  • Point to and name origin of hamstrings
  • What is the role of the hamstrings?
  • Point to posterior cruciate ligament – How would you test integrity?

Station 10 – Venepuncture

  • Communicate with a simulated patient and fill in all relevant paperwork also

Station 11 – Ethics (Hepatitis C)

  • Ethical discussion involving whether you should force patient with suspected Hep C to have a blood test
  • Should you disclose to patient’s sexual partner?
