Question
9 out of 14
 

A 70 years old patient was brought to emergency ward in a comatose state. His ABG was done and findings are as follows Na = 132 meq/lit, K = 6.5 meq / lit,

HCO3 = 10 meq/ lit, blood glucose 20 mmol/lit

BUN = 4 mmol/lit

What is your diagnosis. (AIIMS Nov 2009)



A NKHOC

B D.K.A

C Hypoglycemic coma

D Lactic acidosis

Ans. D

Lactic acidosis

In this case the RBS is 20mmol/lit i.e. 20 X 18 = 360 mg%. So this is not a case of hypoglycemia. Here in this question HCO3 is 10meq/lit so it is not a case of NKHOC. So because this case has metabolic acidosis either it is a case of DKA or lactic acidosis. But as patient age is 70 years it is more likely to be lactic acidosis. Supposed in this question patient age was 17 year than the answer was DKA !!!)
