Primary FRCA exam January 2010

Primary FRCA exam January 2010Physics/ Clinical- clinical was 24 year old 38 weeks pregnant with severe fetal bradycardia. management -catagory of c section. explain anaesthetic technique. is regional CI. say you anaesthetise -then CICV. mx.physics - what is a vacuum. where do we use them. draw scavenging system. explain whyhigh flow low pressure. where is low flow high pressure used in anaesthetics. draw a graph oftemperature decline with anaesthetised patient. what do we do to stop decline. how efficientis it.Set11Physics- Mapleson circuits, efficiency during controlled and SV and why this is the case (inspiration,expiration, expiratory pauses etc.)- Oxygen measurement - different types, explain in detail galvanic fuel cell electrodeincluding equations at both anode and cathode, explain the mechanism of paramagneticanalyzer- Symbols on anaesthetic equipment. Very small print stuff - symbols for manufacture date,symbol for expiry date, symbols for different types of sterilisation. Didn't know a single oneof them but the examiner was very patient and guided me through (e.g. what does this looklike? an egg timer, oh it's probably expiry date then)ClinicalYoung motorcycle RTC victim, compound tib fib no other injuries but may be hepatitispositive.- First question mostly regarding preop assessment and how you would anaesthetise him- Second question - develops high airway pressures and hypotensiobn. Differentials.Treatment of anaphylaxis- Third question - talk me through what you would do following a needlestick injury fromthis patientPharmacology- Draw a dose response curve, semi log plot, definitions of agonists and antagonists and theirdose response curves- Volatiles - compare sevo and des in terms of physical properties and how this affects theiraction- Drugs acting on platelet function - I asked and was allowed to eat up some time bydescribing steps in platelet plug formation. Spoke about aspirin and NSAIDs. I couldn't recallhow clopidogrel worked and couldn't recall a name for a GIIb/IIIa inhibitor (tirofiban waswhat I was after).15
