ABGS (2)

Question 1

interpreting ABGs includes

Answer 1

Ph acidosis or alkalosis

respiratory or metabolic

compensation

Question 2

If pH and PaCO2 are in the acidic column, what does this indicate?

Answer 2

respiratory acidosis

Question 3

If pH and PaCO2 are in the alkaline column, what does this indicate?

Answer 3

respiratory alkalosis

Question 4

If pH and HCO3 are in the acid column, what does this indicate?

Answer 4

metabolic acidosis

Question 5

If pH and HCO3 are in the alkaline column, what does this indicate?

Answer 5

metabolic alkalosis

Question 6

Mr. Miller has a pH of 7.26, PaCO2 of 42 and HCO3 of 17. What state is he in?

Answer 6

metabolic acidosis

Question 7

Mrs. Silver has a pH of 7.49, PaCO2 of 30, and HCO3 of 23. What state is she in?

Answer 7

respiratory alkalosis

Question 8

How does respiratory system compensate for metabolic acid-base imbalance?

Answer 8

by regulating CO2 levels

occurs in a matter of seconds

Question 9

How does the renal system compensate for respiratory acid-base imbalance?

Answer 9

by increasing excretion of H+ and reabsorption of HCO3

can take 12-72 hours

Question 10

3 kinds of compensations

Answer 10

uncompensated

partial compensation

full compensation

Question 11

how to tell if its compensated or not

Answer 11

look at the parameter NOT associated with the pH

Question 12

If the PaCO2 or HCO3 (not associated c pH) is in normal column, what is the compensation?

Answer 12

no compensation

Question 13

If HCO3 is alkaline but her pH and PaCO2 are acid, what is the compensation?

Answer 13

respiratory acidosis with partial compensation

can occur with low intensity therex

Question 14

If PaCO2 is acid, and pH and HCO3 are alkaline, what is the compensation?

Answer 14

metabolic alkalosis with partial compensation

Question 15

If the pH is in the normal column and the other parameters are not, what is the compensation?

Answer 15

full compensation

must recalculate for pH using 7.4 (if below then acid, if above then alkaline)

Question 16

Documenting recalculation for pH

Answer 16

original pH value - pHi

adjusted pH value - pHa

Question 17

If pH is 7.36, HCO3 is 34, and PaCO2 is 50, what is diagnosis?

Answer 17

respiratory acidosis with full compensation

pHa is in the acid column ( <7.4)

Question 18

Interventions to improve abnormal ABGs include:

Answer 18

biomechanics of breathing

airway diameter

alveolar ventilation and oxygenation

pulmonary hygiene

Question 19

Besides ABGs _________ and _________ are important to consider to assess current state of patient

Answer 19

observation

auscultation
