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

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
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.

Electrocardiogram in the Cs5 configuration. What are you looking at when monitoring lead I.
A. anterior ischaemia
B. atrial
C. inferior
D. lateral
E. septal - CORRECT ANSWER-ANSWER A
The central subclavicular (CS5) lead is particularly well suited for the detection of anterior myocardial
wall ischemia. The right arm (RA) electrode is placed under the right clavicle, the left arm (LA) electrode
is placed in the V5 position, and the left leg electrode is in its usual position to serve as a ground.
Lead I is selected for detection of anterior wall ischemia, and
lead II can be selected for monitoring inferior wall ischemia or for the detection of arrhythmias. If a
unipolar precordial electrode is unavailable, this CS5 bipolar lead is the best and easiest alternative to a
true V5 lead for monitoring myocardial ischemia.
