Answer 2

7.25-7.35

Question 3

What is normal ARTERIAL pCO2 ?

Answer 3

35-45 mmHg

Question 4

What is normal VENOUS pCO2?

Answer 4

41-51 mmHg (+6 for each compared to arterial)

Question 5

What is normal ARTERIAL p02?

Answer 5

80-100 mmHg

Question 6

What is normal VENOUS pO2 ?

Answer 6

35-40 mmHg

Question 7

What is normal VENOUS HCO3- ?

Answer 7

22-26 mmHg (based on slide, which also has arterial at 22-26, stays same as arterial), Master Sheet has arterial as 21-28

Question 8

What is normal ARTERIAL HCO3?

Answer 8

21-28 mmol/L (other source says 22-26, also VENOUS HCO3 = ARTERIAL HCO3)

Question 9

What is normal ANION GAP ?

Answer 9

3-11

Question 10

Convert 1 mmol of NaCl to mEq

Answer 10

1 mmol of NaCl = 2 mEq of NaCl (two valencies)

Question 11

Convert 1 mmoL of K+ to mEq

Answer 11

1 mmol of K+ = 1 mEq of K+

Question 12

Convert 1 mmol of CaCl2 to mEq

Answer 12

1 mmol of CaCl2 = 4 mEq of CaCl2 (total of 4 valancies)

pCO2 48
HCO3 31

Answer 23

Fully Compensated Metabolic Alkalosis

Question 24

pH 7.42
CO2 33
HCO3 20

Answer 24

Fully Compensated Respiratory Alkalosis

Question 25

pH 7.33
CO2 33
HCO3 19

Answer 25

Fully Compensated Metabolic Acidosis

Question 26

What is the equation to calculate mEq given a certain amount of substance ?

Answer 26

mEq = ((Amount in mg) x (# of valency)) divided by MW (but covert g/mol to mg/mmoL because you need same units)

Question 27

If the molecular weight of NaCl is 58.44 g. And you have 116.88 g. Calculate the mEq. (**beyond Sem 1)

Answer 27

mEq = (amount x valency) / MW expressed as mg/mmoL

mEq = (116.88 x 2) / 58.44 mg/mL (easy conversion, number stays the same g –> mg, and mole to mmol…..so # same)

mEq = 4 mEq of NaCl

Question 28

pH 7.13 , pCO2 19, HCO3- 11

Answer 28

EXTREME Metabolic Acidosis, partially compensated.

pH LOW, HCO3 LOW, pCO2 LOW

Question 29

pH 7.54
CO2 7
HCO3 12

Answer 29

Respiratory Alkalosis, partially compensated

pH HIGH, CO2 LOW, HCO LOW
