Question

If we injected lactic acid into the bloodstream of a resting individual and took arterial blood measurements, which of the following numbers make sense? (Assume that there has been enough time for the respiratory system to respond, but not the kidneys)

a. pH=7.2,PCO2=50mmHg,bicarb=23mEq/L

b. pH=7.2,PCO2=30mmHg,bicarb=23mEq/L

c. pH=7.2,PCO2=30mmHg,bicarb=30mEq/L

d. pH=7.4,PCO2=50mmHg,bicarb=23mEq/L

e. pH=7.4,PCO2=30mmHg,bicarb=23mEq/L

Answer 1

Answer ; B). pH = 7.2, PCO2 = 30 mmHg, bicarb = 23mEq/L

Reason ; In the given caser, the lactic acid is injected into the blood stream, so probably the client would develop lactic acidosis. in this condition, the pH level will be definitely low, hence the last two are totally incorrect. The level of the bicarb would be normal in these condition, hence the option C would be considerd as wrong. And the level of CO2 would be readily decreased to counter these condition, hence the above mentioned values would be appropriate for these condition.
