increase in hydrogen ion in the blood

Question 6

Acidosis

Answer 6

increase in hydrogen ions in the tissues

Question 7

Metabolic acidosis

Answer 7

low bicarbonate in the presence of normal pressure of carbon dioxide values

Question 8

Respiratory acidosis

Answer 8

high carbon dioxide values with normal bicarbonate levels

pH: >7.10
Carbon Dioxide (PCO2): <60
Bicarbonate: >22
Base Deficit: <12 or >-12
Partial Pressure of Oxygen (PO2): >20

Question 11

Normal Maternal ABG Values:

Answer 11

pH: 7.35-7.45
PCO2: 35-45
HCO3: 22-26

Question 12

Which is the respiratory component in the maternal ABG’s?

Answer 12

PCO2- which is an acid

Question 13

Which is the metabolic component in the maternal ABG’s?

Answer 13

HCO3- think kidneys this is a base

Question 14

What are the abnormal values for each ABG value?

Answer 14

pH: <7.35: acidosis; >7.45: alkalosis
PCO2: <35: alkalosis; >45: acidosis
HCO3: <22: acidosis; >26: alkalosis

Question 15

Metabolic Acidemia

Answer 15

This is a decrease in the pH/ depleted base in the blood

Question 16

Answer 16

Shunt blood to brain, heart, and the adrenal glands
