Answer 5

> 95%

Question 6

what are normal PaCO2 levels

Question 7

what are normal HCO3 levels

Answer 7

22-26mEq/L

Question 8

what tells us how acidotic or alkalotic our blood is

Answer 8

pH

Question 9

what tells us the amount of oxygen dissolved in arterial blood

Answer 9

PaO2

Question 10

what tells us the saturation of oxygen on hemoglobin

Answer 10

SaO2

Question 11

what is regulated by the lungs

Answer 11

PaCO2

Question 12

what is regulated by the kidneys

Answer 12

HCO3

Question 13

what is the body FASTEST way to change our pH

Answer 13

lungs because they regulate CO2 (acid) levels within minutes

Question 14

how do the lungs compensate for acidosis

Answer 14

RR and depth will increase and CO2 will be blown off

Question 15

how do the lungs compensate for alkalosis

Answer 15

RR and depth will decrease and CO2 will be retained

Question 16

what is our “base”

Answer 16

bicarbonate

Question 17

what is our “acid”

Answer 17

carbonic acid

Question 18

the ______ regulate _____ levels but its a ______ system, takes hours to days

Answer 18

kidneys; HCO3; slower

Question 19

how do our kidneys compensate for acidosis

Answer 19

H+ ions will be excreted and HCO3 will be retained

Question 20

how do our kidneys compensate for alkalosis

Answer 20

H+ ions will be retained and HCO3 will be excreted

Question 21

if pH is less than 7.35 what is it

Answer 21

acidosis

Question 22

if pH is more than 7.45 what is it

Answer 22

alkalosis

Question 23

if PaCO2 is less than 35 what is it

Answer 23

Question 33

excessive vomiting ingestion of excess sodium bicarb prolonged gastric lavage administration of potent diureticss

Answer 33
