Final FRCA viva questions from June 2011 exam
Coventry collection: Many thanks to the candidates form June 2011 Course 1
Some general feedback for the day for any future candidates:
During the exam, as all candidates take the exam in small booths all in the same room, thenoise levels can be quite high and during pauses to think, it is possible to hear candidates in
the next booth answering their questions! Don't let this put you off! It can be quite
distracting but you really do need to ignore any other conversations.
Some of the radiographs are on computer screens now, and will be shown as such during
the 10 minute prep as well as on paper too. In the examiners booth, the CXR was on acomputer screen not on paper.
Practice the timing for your 10 minute preparation for your long case with a watch you can
wear to the exam. Where I was sat, you couldn't see a clock and so couldn't work out howmuch of the 10 minutes had elapsed. Consequently, even though I had always been well
under the 10 mins prep time in my practices, on the day I just ran out of time.
The examiners may move you on quickly and sometimes want quite 'punchy' answers.Don't let this upset you, go with where they are directing you and be flexible in your
approach with your answer structure. But in general, start broad, classify and work towardsthe details.
The examiners may really push you and come across quite mean! In my science viva, I
thought I was doing badly and nearly felt defeated but picked myself up and pushed on. Atthe end, when I'd passed and was chatting to the examiner with a glass of wine in hand he
said he knew I'd passed and was pushing me to get to the minutiae, and all along I thought
I was failing! You will be a bad judge of how you're doing so keep going, don't getdefeated or angry!
Set1
21 year old 32 weeks pregnant lady presents to Ante natal ward with chest pain and
breathlessness on exertion and rest, she did not receive her antennal appointment as shewas worries that they will advise her to terminate her pregnancy as they did 2 years back,
so she has not been seeing anyone since 3 years, she is known to have a bicuspid Valve(
Aortic Valve)ECG T wave inversion in Lead III and V1 rest all ecg Normal
ECHO - Peak gradient 78 mm of Hg and mean 38mm of Hg

Questions i was asked
Summrise
InvestigationsWhy she is breathless- AS and preg fixed CO state, details of cardiac changes in preg
affecting AS
Managemant She should have a elective LSCS. Examiners happy with answer not tokeep her in DGH , transfer her where facility exists for Valve replacement.
Now in tertiary centre How would you anaesthetise her.
In this i Answered as we tend to answer like , consent , monitoring , invasive , blood loss ,temp , urine output .
GA/ RA . why not Spinal and what are advantages of CSE
What monitorning
Drugs Thio and eximers asked any other drug ( Etimidate ) with TAP Block . Multimodalanalgesia
Now she Bleeds Management Ergometrine avoid Oxytocin as it causes Hypotension
and decreases SVR which is not good for her , also prostaglandins like PGF2a and PGE2
Where will she be after words post op (HDU/ITU) depending on how operation goes.
Management on ITU . FLATHUGWhat about Breast feeding opoids and Benzodiazepine .
Short Cases
1.ECT What is ECT, How is it helpful , how does it works ,Q-What are key in preop management
Answer-Full history, lots of comorbidities , HTN , IHD , COPD , Poor historiens ,
Aspiration risk. Allergies , prev anaesthetic charts impQ- Drugs like litium how does it affect Anaesthetic drugs
Q- what changes does ECT prodA- On saying parasympathetic and Symp , they showed me a ECG where initial
aystole and then tachycardia .
B- I answered making sure that leads are not disconnected and feel for pulse if needed
use glycopyrolate and then atropine.
Q how would u anaesthetise her , what precautions will u take ?
A- Good pre op work up , as done in Isolated conditions if any risk factors i would do itwhere help can arrive and if no risk factors , Machine check , drugs ready , AAGBI
monitoring, trained assistant , Sr help around,and standard....................
Short case 2Pre-assement calls you that a lady has arrived for elective cholecystectomy and
mentions that lady says she suffers with Sickle cell Anaemia and nurse knows nothingabout the disease what will be your advise .
Initially i answered- to do basic check up take blood pressure and bloods for
electrophoresis or Sickeldex test and ECG then it clicked to me that there will be moreto the questions and i answered that i will ask the nurse to wait and i will down myself

Long Case
Middle aged gentleman for emergency laparotomy with one day history of abdo pain andvomiting. He has a mass in right groin.
Past history of alcohol and long term smoker.
Bloods essentially normal except:MCV raised
Low sodium
Mildly raised urea
CXR - Chronic fibrotic changes throughout with apical scarring in left upper zoneECG - Fast AF
Summarise the case
What would be your differential? - strangulated hernia, ischaemic bowel, cancer, appendixmass (in the groin!? - I said you cant rule it out if it was retroperitoneal - they were happy)
Describe the X-ray and ECG - I said I want to repeat the ECG as it wasnt a great trace butI said I would treat - with what? I mentioned beta blockers would not be beneficial in a
respiratory patient and digoxin in sepsis has poor results so I would treat with a loading
dose of amiodarone of 300mg into a large antecubital vein in a HDU environment or
certainly with ECG monitoring and BP measurement. Where would I do this? Either on theward or in my recovery if the ward staff were not available.
What other investigations would you want - ABG and PEFRDo you want an ECHO?? - I said firstly I would ask more about his exercise tolerance in
my history in order to gain a functional status and consider this if his exercise tolerancewas limited or if on auscultation I heard a murmur - however I wont delay surgery for it asit wont change my management - they were really happy with this as I think everyone was
saying just get an ECHO when there was no real clinical indication.
Anything pre-op?- I said get the chest physios to come and show him exercises to do and consider pre-op
nebs
How will you anaesthetise?RSI, Routine stuff, No plan for epidural as WCC high and SIRS - MASTER trial
mentioned and they were happy with my analgesic plan of TAP blocks and PCA
Art line, no CVP, Catheter - aim 0.5ml/kg/hr, consider CVP line intra-op on the table ifhameodynamically unstable but BP had NEVER been a problem.
Post-op - HDU, DVT Gastric prophylaxis and feeding
Relatively straight forward!

you choose for day case and why. Indications for discharge from Day surgery
Elderly male for carotid endarterectomy shown ECG LBBB with 1st degree HB - would
you anaesthetise? I said not without further history and examination and a referral to the
cardiologists - if there was an associated LAD this would be trifascicular block and anincrease risk of periop complete heart block. Brief discusiion of GALA trial - what do I do
and why
12 year old for middle ear surgery - choleasteatoma - diabetic.
What is a cholesteatoma
What are the issues here - child/shared airway/long case/micro surgery requiring minimalblood loss for surgical field/facial nerve monitoring
What would you do?
Pre-op assess/Exam etc
Remi infusion - intubate on remi and avoid NDMR completely - have I done this before -yes - describe!
What sort of tube - South RAE or reinforced ETT NOT AN LMA at all - why- want to
control CO2 and long operation !
Basic Sciences
Tell me about the anatomy of the pleura
- what is it? boundaries, what does it cover- innervation
- how can it be damaged?
exudates/transudates/blood/air- how do you insert a chest drain?
- what is the recommendation regarding ultrasound of the chest before insertion
How do end-stage liver patients present to intensive care
- bleeding - upper GI - varices, ulcer disease, portal hypertension
- ascites and spontaneous bacterial peritonitis- encephalopathy
- physiological changes - I just said things in a very systematic way for each system and
they let me talk for pretty much all of the time and were nodding their heads so I just
carried on until they told me to stop - I related everything I mentioned to anaesthesia andpoor prognostic indicators etc. so tried to show I had experience of these type of patients
and also the fact that sometimes if they are end-stage the decision may be to allow natural
death and supportive palliative care - they actually like that!
You have a patient presenting for elective surgery who has had a renal transplant. What
drugs do these patients take and how will this affect your anaesthetic?- firstly discussed necessity of surgery
- drugs - steroids - in depth! including replacement and equivalent doses perioperatively
- cyclosporin - how it works - t cell associated and what it does - pharmacodynamics
- any newer agents you have heard of - tacrolimus - less side effects

Haematology WCC upper border normal (though I said it was all essentially
normal so he asked about the WCC so I said at 0.1raised is essentially normal)ECG AF Echo dilated LA probably accounting for AF and no thrombus
So how would you proceed with this case?
More history (he said what Cardiovascular and Respiratory and how todifferentiate between these)
What other investigations would you need?CXR and ABG/Spirometry if chest was bad, and some functional cardiac testing as
poor mobility and these are usually vasculopaths.
What do you mean by functional cardiac testing?These range from exercise ECG which would not be possible in this case to
pharmacological stress methods.
What methods are these?Dobutamine stress test so how do you carry this out I said inject Dobutamine
and watch the heart function with an echo. Ok, good any other tests? Dipyridamole-
Thallium scan how does this work dilation of the arterioles with Dipyridamole andthen watch for cold/hot spots. Ok, any other test? CPEX test but would be challenging
in him with the bike so would opt to use a hand bike.
Tell me about CPEX testing Ran through airy room, standard monitoring and
airway gases, resus equipment, exercise bike/hand bike, metabolic cart (his eyes glazed
over then), pneumotachograph. Measurement of Vo2/VCO2 ratio and AT. That of11ml/kg/min being the defining number for good post op recovery.
What drugs would you have him on?
Statin, didnt need any hypertension or diabetic control but I would consider ratecontrol and need to consider why hes not on Warfarin as per the NICE guidelines.
If he was on a NSAID would that bother you with putting in an epidural?No
So how would you carry out the anaesthetic if youd had all of the investigations
and optimized fully?Started simply with equipment (cell salvage, invasive monitoring), bair hugger
over upper half why warming? said all patients should be warm as per NICE
guidelines and also coagulation reasons. Drugs, awake epidural. He then asked me how
Id put it in said consent, iv access, trained assistant, monitoring, sitting, full asepsis
and he moved me on! Invasive monitoring.
So you said cell salvage how does that work
Dedicated suction to a reservoir, washed (with what said Im not sure I presume
saline he said yes!) centrifuged and then the packed cells are collected through a filter
20-40nm. What are the cells suspended in - said wasnt too sure.
Ok youre half way through the case and the surgeon releases the clamp and
theres a large amount of bleeding what do you do?
Surgical and anaesthetic things. Start with anaesthetic: give blood that I would havein theatre ready for an AAA, coagulation factors.

Ok what factors. I said FFP 15u/kg for APTR or PT below 1.5 but as per the massive
haemorrhage AAGBI guidelines more if there is micro vascular oozing, and considercryoprecipitate if fibrinogen under 1g/dl. Also think of tranexamic acid 1g as an
antifibrinolytic. But the tests for APTT and Pt might take a while to come back so need
to treat pre-emptively
What about platelet levels?Aim above 75 as per AAGBI guidelines
But what would you do first get the surgeon to put the clamp back on. He smiled!
What other near bedside tests are there that may guide you?
TEG
So what does the TEG tell you?Platelet function, but gives no indication of actual numbers
Then puts up a normal TEG on the screen (said normal TEG on the icon!) so asked meto run through it.
Little hazy here but said it looks globally normal as has the characteristic port
glass shape, short R time (what does that measure time to initial fibrin) then angle,
then the MA speed of clot strengthShowed abnormal TEG essentially similar at the start but shorter and was a
characteristic picture of fibrinolysis
SHORT CASES:
5 yr old bleeding tonsil.Essentially straight out of any viva book problems, assessment, fluid resuscitation,
blood loss estimation, whats circulating volume of child? Said 70ml/kg. So whatwould his be? Some rapid fire maths said estimate weight of 18kg. Then thoughtnever multiply 70 by 18 so I said Id presume 20kg for now and said 1.4l. She seemed
happy. technique for anaesthetising RSI vs Inhalational (but what would you do RSI),
equipment, ENT surgeon, ant emetics, pain relief.
67yr old female presenting with right lower lobe carcinoma and needs a lobectomy.

FEV1 (forced expiratory flow in 1s) 1.4FVC reduced
FEV1/FVC 58% - obstructive
FEF 25-75. What is it? Guessed at forced expiatory flow. What does it measure? Small
airways. So its lowered by what: Emphysema, Fibrosis, and Anaemia
TLCO Transfer factor for CO. What does this show surface area of the lung. How dothey measure it. Get patient to breathe in CO. Breathe in CO examiner looked

horrified, threw me a bit as I was a bit taken by surprise but anyway stuck to my guns
and said yes, but not a lethal amount. So how much I dont know but certainly below10%! yes I think that would be a safe bet!
So how would you asses this ladys fitness for surgery?Cardiovascular and respiratory parameters
Respiratory ones?
BTS guidelines: FEV1 should be more than 1.5 for the lobectomy and this is low sowould need to estimate post op. Ok how do you do this well could V/Q scan. Any
other quicker way?
Lung broken down into bronchopulmonary segment. Right well if youve lost thelower lobe on the right what does that leave you with. Again maths in a stress situation
so I said well there are 3,2,5 on the right side, so that would be five from the 10. She
laughed and pointed out there are two lungs so did they both have the same number of
segments. Oops! Theres 9 on the left so leave 5/19 (thankfully didnt have to work thatout as a number!)
And cardiovascular? CPEX would be gold standard seemed happy with that and
moved on.
43 yr old male spinal cord transaction 2 yrs ago at T2 presents for renal stone surgery.What are the issues. Essentially straight out of a viva book.
Several systems: resp lost intercostals, so diaphragmatic, poor cough,
Cardiovascular bradycardia, postural hypotension
Autonomic Hyperreflexia tell me about this, what happens, what causes itThermal control
Pressure sores
DVTRecurrent UTIs
Hard veins
Bell went. The clinical long case was quite weird really. 2 very stern looking examiners
who were very business like, difficult to get any rapport going at all- We all came out
thinking it was too easy and straight forwards, with not much meat to the question atall. They jumped around quite a bit so keeping your train of thought was difficult.
Short cases very fair 2 straight out of the viva books (so no complaints). The
pulmonary function tests were more iffy, but again they are all in the books and thepre-op resp carcinoma is also in the books. So, on the whole pretty fair.

Tell me about the mediastinum.I said it was an area of the neck and thorax split in to
4: superior, middle, anterior and posterior.
What structures do each contain and can you point them out.Said thymus in the
neck in the superior ok, what about the vasculature. Went through each in turn
which, as there was a picture on the screen was really straight forwards. They wantedthe Aorta, brachiocephalic, subclavian, common carotids. Then jugular, subclavian,
brachiocephalic, SVC. Wheres the pulmonary veins, pulmonary artery, where would
the ductus venosus run, wheres the thoracic duct ( I said on the left side but I cantactually see it on this screen as it should be draining into Left subclavain he had a
look and agreed it wasnt there!) Name some nerves that traverse through the
neck/chest and abdomen vagus. Where does it lie in the neck T-O groove. Wheredoes the oesphagus start and how long is it.
Why is the oesophagus important to anaesthetists?Mode of feeding so placement of NG
Mode of monitoring: Doppler/ TOE/tempInadvertent injury: bougie, trache
Air into stomach esp in children/LMA regurg risk
Inadvertent intubation
Then he looked as if we had covered what he wanted to so took a few seconds looking
at the paper before askingHow would you anaesthetize for food bolus removal ?Checked it was definitely in the oesophagus. Yes. So history, examination and
investigations. Yes theyre all ok. Well If the airway wasnt difficult would do iv
induction and intubate. Care needed as it will be a shared airway, and need to make
sure patient is fully paralysed if they are going to use a rigid scope.
Physiology: Free flap surgery
What different types of flaps are there, and whats the differences between them
blood supply pedicle flap vs free flap.How do you look after a patient with Free flap.Maintain good oxygenation, MAP but with careful use of vasoconstrictors as these
decrease flow to the flap and actually want to modify the rheology of the blood
haematocrit as per the Pouiselles equation (at which case he switched off), so talkedabout keeping warm, vasodilator drugs, leeches,
Pharmacology:
Antibiotics who would you use antibiotics for pre-operatively?
Essentially a run through of the surgical site infections guidelines about antibiotics.Talked about patient factors and surgical factors (clean, clean-contaminated,
contaminated, dirty.. and wanted examples of these) , implants, at risk patients
diabetics, immunocompromised, IE prophylaxis. Wound dressings. Patient and staffeducation. Taylor therapy to potential pathogens. Wanted examples of what to use for
bowel surgery: need anaerobic cover metronidazole, and orthopaedic? At my hospital
we give gentamycin and Flucloxacillin to cover staphylococci. Ok what about MRSA?
Talked about colonization vs infection. Then education of patients and staff.Handwashing. Aprons and gloves, isolation. Use of specific antibiotics as per

sensitivities what would you use. Vancomycin. If they had renal failure what would
you use would speak to the microbiologist for advise of sensitivities and what thehospital policy was, but could consider Linezolid!
Physics:
Straight out of a viva book: tell me about the problems of anaesthetizing a patient in an
MRI scanner.Problems with isolated area, magnetism, noise, equipment and monitoring, condition
why needing MRI scan often children.
Basically a run through how it affects all these in turn lots of time on monitoring andequipment, whos contraindicated pacemaker 5 gauss (though now can get MRI safe),
aneurysm clips. Infusion pumps 30Gauss. Different monitoring. Mentioned ear plugs
would you use in an anaesthetized patient. Said yes as anaesthetic doesnt affect
pressure wave (had no idea though!). Quenching, missiles from ferrous material. Thenhow does MRI work in the last minute of the viva. So got to alignment of the atoms
and then apply magnet and the bell went!
Again I thought an extremely fair viva. All the topics were pretty straightforward.
Many found the mediastinum question threw them as it is not in the books howeverthere was the picture on the screen and pointing out the aorta etc shouldnt be too
difficult to work out on your feet. Examiners were much more interactive in this exam
and it was more like a chat between us three as opposed to an actual viva- actually
enjoyed it by the end. However the questions clearly suited me.
Other vivas I heard about on the day for the long case: Scleroderma and CREST
syndrome in the long case. Short cases femoral triangle, pleural anatomy and chestdrains, osmosis/osmolarity, chemotherapy drugs for renal transplantation and the
indications for transplant and side effects of the drugs.
Interestingly when talking to the examiners afterwards I said I thought that had I got
the science viva with pleura/chemotherapy/osmolarity it would have been much harder
however 70% of candidates passed the exam that day. 57% passed with the questionswe had which is interesting as I thought they were more middle of the road questions.
The Monday cohort had a 50% candidate pass- so I am glad I didnt sit then!

1) Young lady for laparoscopic sterilization. Had PONV with previous operations.- What will you tell her (in lay language)
- Why is she at risk (discussion of risk factors: Patient, surgical and anaesthetic)
- What can you do to decrease risk (non-pharmacological Vs pharmacological)
- Tell me about pharmacological which receptors can you block (+example), howdoes ondansetron work, whats the incidence of PONV, how is this affected by
ondansetron (I happened to know of one study in gynae patients where incidencereduced from about 50% to about 26% with addition of Ondansetron). Any side
effects or contra-indications

- Treatment differences with tension pneumothorax
- Treatment differences with spontaneous pneumothorax (BTS guidelines)
- He also has a dislocated shoulder on the other side and the trauma surgeon asks youto give him a quick GA so he can reduce it [High risk case, needs transfer to
theatre and GA in safe environment. Avoid N2O. Wanted to hear that IPPV can
convert a simple pneumothorax to a tension. LMA +SV not fasted. Avoid
brachial plexus blocks phrenic nerve block (interscalene) or pneumothorax(infraclavicular/subcoracoid) on other side to existing pneumothorax would be
disastrous.]
