Acid Base CIS

Question 1

shortness of breath and anxiety

pH 7.52
PCO2 30
HCO3 22
Na 138
K 4.1
Cl 106

Answer 1

1. pH up so alkalosis
2. bicarb is opp direc of pH so respiratory
3. uncompensated
4. anion gap is normal so no metabolic acidosis 138-22-106 = 10
5. no need to calc delta AG
6. respiratory, skip this
7. Matches clinical picture

Question 2

cachectic, concerned about weight

pH 7.45
pCO2 52
HCO3 38
Na 132
K 3.1
Cl 86

Answer 2

pH high- alkalosis
HCO3 is high, following pH, so metabolic
pH isnormal- compensated
4. AG is 8
5. no gap so skip
6. 
7. clinical picture
