Question 2

The second fastest pH compensation system

Answer 2

Respiratory buffering system

minutes

Question 3

The slowest pH compensation system

Answer 3

Kidneys (hours to days)

Question 4

Normal ratio of Bicarbonate and carbonic acid

Answer 4

20:1

Question 5

The function of the Carbonic Buffering system

Answer 5

Purpose is to eliminate CO2, combines CO2 with H2O creating carbonic acid, due to its instability splits into H and Bicarb

Question 6

The function of the respiratory buffering system

Answer 6

Adjusts pH by blowing off or holding on to CO2

Question 7

The function of the Kidney buffering system

Answer 7

Kidneys can absorb or excrete HCO3 or H as needed

Question 8

Normal pH range and perfect value

Answer 8

7.35-7.45 (7.4)

Question 9

Normal PaCO2 range and perfect value

Answer 9

35-45 (40)

Question 10

Normal HCO3 range and perfect value

Answer 10

22-26 (24)

Question 11

Relationship between CO2 and pH

Answer 11

For every 10mmHg in CO2 there is an opposite change in pH by 0.08

Question 12

Relationship between HCO3 and pH

Answer 12

For every 10mEq/L in HCO3 the pH will change by 0.15 in the same direction

Question 13

Relationship between K and pH

Answer 13

For every 0.10 change in pH the K will change by 0.6mEq/L in the same direction
