1. Primary metabolic acidosis, with a normal anion gap,
with superimposed respiratory alkalosis
pH > 7.45- alkalosis, pH < 7.35, acidosis
Therefore this patient is suffering from acidosis as his pH which is 7.33 is less than 7.35
Normal Partial pressure of carbon dioxide (PaCO2): 35-45 mmHg
Therefore the PaCO2 of this patient is less than normal 20mmHg.
Bicarbonate (HCO3) normal value: 22-26 mEq/L
2. Chronic (compensated) primary respiratory alkalosis
pH > 7.56 and HCO3 > 19, for acute (uncompensated)
pH < 7.43 and HCO3 < 14, for chronic (compensated)
solve these 2 problems below: ph 733 , PaCO2 is 20mmhg, HCO3 is 25 ph 744,...

HCO3 + HCO3 = Acid Base 3. Complete the table of values below for the aqueous solutions at 25°C using your calculator. (No need to show your calculation here) [H] [OH-1 PH рон 2.7 x 10-8 M M 8.60
A 100.00 mL buffer solution at pH 7.80 is prepared such that the [H2CO3] + [HCO3] = 1.000 M. Determine how much strong acid 1.00M HCI or strong base 1.000 M NaOH must be added to change the pH to 7.40. The step-wise acid dissociation constants for carbonic acid are Ka1= 4.2*10^-7 ; Ka2= 4.8*10^-11.
Question 15 of 25 Submit What is the conjugate acid of the Brønsted-Lowry base, HCO3-?
Calculate the missing value. Report pH to 2 decimal places. Report [HCO3-] to 1 decimal place. Indicate whether the patient has an acidosis or an alkalosis. Indicate whether the primary disturbance is respiratory or metabolic and whether it is uncompensated, partially compensated, or fully compensated. This patient hasn’t eaten in over 24 hours. pO2 = 110 mm Hg pCO2 = 30 mm Hg [HCO3] = 17 mmole/L base excess = -2 mmole/L pH = acid/base status:
