A. Subcostal nerve
,B. Obturator nerve
C. Lateral cutaneous femoral nerve

QUESTION >You are called to see a 30 year old man with rapidly deteriorating asthma. Following
appropriate medical management an endotracheal tube is inserted and he is ventilated with a
mechanical ventilator with a tidal volume of 600ml and a rate of 12 breaths per minute. Five minutes
later the blood pressure is unrecordable and external cardiac massage is commenced. Arterial blood is
taked and shows ph 7.08, pCO2 96 mmHg, pO2 36 mmHg, SpO2 46% and bicarbonate 27 mmol/L. He is
administered adrenaline, salbutamol, pancuronium, bicarbonate and calcium gluconate. The ECG shows
sinus rhythm at a rate of 60 beats per minute. The patient remains pulseless and cyanosed with fixed
dilated pupils and distended neck veins. The most appropriate management is to
A. cease resuscitation
B. administer further adrenaline
C. insert bilateral intercostal drains
D. cease ventilation for 30 seconds and resume at a slower rate
E. incre - CORRECT ANSWER~ANSWER D
QUESTION>A 42 year old lady presents for right pneumonectomy with a left sided double-lumen tube.
She is 132kg and 160cm. What depth, measured at the incisors, is likely to give the ideal position?
A. 24cm
B. 26cm
,C. 28cm
D. 30cm
E. 32cm - CORRECT ANSWER~ANSWER C
Millers formula:
Depth= 12 + (pt height cms/10)
therefore 28 in this case.
QUESTION>Features of severe pre-eclampsia include all except:
A. Foetal growth retardation
B. Peripheral oedema
C. Systolic BP more than 160
D. Thrombocytopenia
E. Severe proteinuria - CORRECT ANSWER~ANSWER B
QUESTION>A 20 year old man was punched in the throat 3 hours ago at a party. He is now complaining
of severe pain, difficulty swallowing, has a hoarse voice and had has some haemoptysis. What is your
next step in his management?
A. Awake Fibreoptic Intubation
B. CT scan for laryngeal fractures
C. Direct laryngoscopy after topicalising with local anaesthetic
D. Nasopharyngoscopy by an ENT surgeon
E. Soft tissue xray of the neck - CORRECT ANSWER~ANSWER D
QUESTION>A 60 year old man with normal LV function is having coronary artery bypass grafting. After
separation from the bypass machine he becomes hypotensive with ST elevation in leads II and aVF. The
Swan Ganz Catheter showed a PCWP of 25 and CVP of 15 with normal PVR and SVR. The TOE is likely to
show:
, A. Early mitral inflow > inflow during atrial systole
B. Inferior wall hypokinesis
C. Severe MR
D. TR and RV dilatation
E. LV cavity obliteration at the end of systole - CORRECT ANSWER~ANSWER B
QUESTION>What is the test is decreased in Iron deficiency anaemia?
A. microcytosis
B. serum ferritin
C. serum iron
D. transferrin
E. total iron binding capacity - CORRECT ANSWER~ANSWER B
serum ferritin
Serum Iron is also low but is low in Anaemia Chronic Disease too, whereas ferritin is more specific for Fe
Deficiency.
in Fe deficiency anaemia transferrin/Total Iron Binding Capacity is increased, as total body stores of iron
are low and the carrier molecule (transferrin) is being underutilised. Therefore Transferrin SATURATION
will be low also.
QUESTION>A full size C oxygen cyclinder (size A in New Zealand) has pressure regulated from
A. 16000kpa to 400kpa
B. 16000kpa to 240kpa
C. 11000kpa to 400kpa
D. 11000kpa to 240kpa
E. 7600kpa to 240kpa - CORRECT ANSWER~ANSWER A
