NUR 110 Test 5
- arterial blood gases
Answer clinical test on arterial blood to identify the levels of oxygen and carbon dioxide
- Blood pH
Answer 7.35 (acid)-7.45 (base)
- PCO2 normal range
- HCO3 normal range
- hypoxemia
Answer 45 (acid)-35 (base) Respiratory Regulated by lungs
Answer 22 (acid)-28 (base) bicarbonate regulated by kidneys Metabolic
Answer deficient amount of oxygen in the blood
- PaO2
Answer 80-100mmHg
Hypoxemia results if this is too low 60-79 mild 40-59 moderate 1 / 3
less than 40 is severe
- If pH is too acidic
Answer lungs compensate by hyperventilating and blowing off CO2 Kidneys retain bicarbonate
(HCO3)
- If pHis too alkaline
Answer lungs compensate by slowing down reapers (retain CO2) Kidneys retain hydrogen ions (result acid)
- 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
- respiratory acidosis
Answer A drop in blood pH due to hypoventilation (too little breathing) and a resulting accumulation of Co2.
- Respiratory Acidosis
Answer A pH of less than 7.35 and CO2 of more than 45
- Respiratory Alkalosis
Answer A pH of more than 7.45 and CO2 of less than 35 2 / 3
- metabolic acidosis
Answer pH less than 7.35 HCO3 less than 22
- metabolic alkalosis
Answer A pH of more than 7.45 HCO3 of more than 28
- Acidosis
Answer depressant effect on CNS
- Alkalosis
Answer excitatory effect on CNS
- Dyspnea
Answer difficulty breathing result of respiratory acidosis
- cause of respiratory alkalosis
Answer due to hyperventilation, anxiety, mechanical ventilation
- Hypokalemia
Answer deficient potassium in the blood result of respiratory alkalosis
- cause of respiratory acidosis
