In a patient with a plasma pH of 7.1 the HCO3 / H2CO3 ratio in plasma is:
A1
B20
C2
D10
Use the following laboratory values to find the best option that describes the acid-base disorder: Plasma pH = 7.12, Plasma PCO2 = 60 mm Hg, Plasma HCO3- = 19 mEq/L
ACombined metabolic and respiratory acidosis
BMetabolic alkalosis with respiratory compensation
CCombined metabolic and respiratory alkalosis
DRespiratory acidosis with renal compensation
At pKa = pH, what is the relationship between the ionic and non-ionic forms of a drug?
AAbsorption of drug is 50% ionic and 50% non-ionic
BConc. of drug is 25% ionic and 75% non-ionic
CConc. of drug is 75% ionic and 25% non-ionic
DConc. of drug is 50% ionic and 50% non-ionic
