Question 2

CO2 (carbon dioxide)

Answer 2

35-45

Question 3

HCO3 (bicarbonate)

Answer 3

21-28

Question 4

O2 (oxygen)

Answer 4

80-100

Question 5

respiratory response to acid-base imbalance

Answer 5

rapid, not sustained

Question 6

metabolic (renal) response to acid-base imbalance

Answer 6

gradual and sustained

Question 7

causes of respiratory acidosis (retain CO2)

Answer 7

asthma
COPD
restrictive lung disease
excessive sedation

Question 8

causes of metabolic acidosis (retain inadequate HCO3)

Answer 8

ingestion of toxins

uncontrolled diabetes

Question 9

causes of resp alkalosis (excrete CO2)

Answer 9

hyperventilation
mechanical ventilation
ingestion certain toxins

Question 10

causes metabolic alkalosis (excessive amt HCO3)

Answer 10

excessive intake certain meds ie antacids

prolonged vomiting or nasogastric tube suction

Question 11

ROME

Answer 11

Respiratory = Opposite
pH high, CO2 down (alkalosis)
pH low, CO2 high (acidosis)
Metabolic = Equal
pH high = HCO3 high (alkalosis)
pH low = HCO3 low (acidosis)
