Biochemistry: acid-base balance 2

Question 1

state the primary problem in metabolic acidosis

Answer 1

too much H+

Question 2

how is metablolic acidosis compensated

Answer 2

by blowing off CO2, through respiratory system

Question 3

state the primary problem in respiratory acidosis

Answer 3

too much CO2

Question 4

how is respiratory acidosis compensated

Answer 4

by excreting H+ and simultaneously reclaiming HCO3, through metabolic process

Question 5

what is the equation involved in ALL acid-base stuff

Answer 5

H+ + HCO3 <=> H2CO3 <=> CO2 + H2O

Question 6

give some causes of respiratory acid-base disorders (3)

Answer 6

chronic obstructive airway disease
choking
bronchopneumonia

Question 7

give some causes of metabolic acid-base disorders (3)

Answer 7

loss of H+ in vomit
K+ deficiency
loss of HCO3

Question 8

in an ABG measurement how do you identify if its an acidaemia or alkalaemia

Answer 8

look at [H+]
acidaemia = too much H+
alkalaemia = too little H+

Question 9

in an ABG how do you identify if its a respiratory or metabolic problem

Answer 9

respiratory = abnormal pCO2
metabolic = abnormal HCO3
