Acid-Base Disturbance

Question
1 out of 11
 

Interpret the following data.

HCO3 = 8 meq / lit Ph = 7.40

PCO2 = 20 mm Hg PO2 = 90 mm Hg,

Na = 136 meq / lit. K= 4 meq / lit

What is your diagnosis? (AIIMS Nov 2014)



A Uncompensated metabolic acidosis

B Uncompensated. Respiratory acidosis.

C Compensated Respiratory acidosis

D Compensated metabolic acidosis

Ans. D

Compensated metabolic acidosis

In this question the PH is 7.40 (i.e. normal) so acid base disturbance has been compensated so option A and B are ruled out. Here PCO2 is 20 (i.e. respiratory alkalosis) so option C is ruled out.

As PH is 7.4 (compensated) and HCO3 is 8. Hence Option D is the answer.
