NUR 110 Test 51. arterial blood gases
Answer
clinical test on arterial blood to identify the levels of oxygen and carbon dioxide
2. Blood pH
Answer
7.35 (acid)-7.45 (base)
3. PCO2 normal range
Answer
45 (acid)-35 (base) Respiratory
Regulated by lungs
4. HCO3 normal range
Answer
22 (acid)-28 (base) bicarbonate
regulated by kidneys Metabolic
5. hypoxemia
Answer
deficient amount of oxygen in the blood
6. PaO2
Answer
80-100mmHg
Hypoxemia results if this is too low 60-79 mild
40-59 moderate
,less than 40 is severe
7. If pH is too acidic
Answer
lungs compensate by hyperventilating and blowing off CO2 Kidneys retain bicarbonate
(HCO3)
8. If pHis too alkaline
Answer
lungs compensate by slowing down reapers (retain CO2) Kidneys retain hydrogen ions (result
acid)
9. Compensation for imbalanced pH
Answer
Lungs first and kidney follow Lungs work harder if pH is too acidic, blowing off CO2 to
increase acid Breathe slower if pH is too alkaline to increase CO2 (acid)
Kidney follow
Kidneys produce bicarbonate (HCO3) if pH is too low Kidneys produce carbonic acid is pH is
too high
10. respiratory acidosis
Answer
A drop in blood pH due to hypoventilation (too little breathing) and a resulting accumulation of
Co2.
11. Respiratory Acidosis
Answer
A pH of less than 7.35 and CO2 of more than 45
12. Respiratory Alkalosis
Answer
A pH of more than 7.45 and CO2 of less than 35
, 13. metabolic acidosis
Answer
pH less than 7.35 HCO3 less than 22
14. metabolic alkalosis
Answer
A pH of more than 7.45 HCO3 of more than 28
15. Acidosis
Answer
depressant effect on CNS
16. Alkalosis
Answer
excitatory effect on CNS
17. Dyspnea
Answer
difficulty breathing result of respiratory acidosis
18. cause of respiratory alkalosis
Answer
due to hyperventilation, anxiety, mechanical ventilation
19. Hypokalemia
Answer
deficient potassium in the blood result of respiratory alkalosis
20. cause of respiratory acidosis
