ABG Analysis Exam All Possible Questions and Answers with complete solution

6 steps to ABG analysis - Answer-1. is the pH normal? 2. Is the CO2 normal? 3. IS the HCO3 normal? 4. Match the CO2 or the HCO3 with the pH 5. Does the CO2 or the HCO3 go the opposite direction of the pH? 6. Are the PO2 and O2 saturation normal? 1. Is the pH normal? - Answer-normal range is 7.35-7.45 acidosis is less than 7.4 alkalosis is greater than 7.4 2. Is the CO2 normal? - Answer-Normal range is 35-45 acidosis is greater than 45 alkalosis is less than 35 3. Is the HCO3 normal? - Answer-normal range is 22-26 acidosis is less than 22 alkalosis is greater than 26 4. Match the CO2 or the HCO3 with the pH - Answer-CO2 = respiratory problem HCO3= metabolic problem ABG Chart - AnswerAcid-Base (ROME) - Answer-R-espiratory O-ppositeM-etabolic E-qual Arterial Blood Gas Interpretation - Answer- 5. Does the CO2 or the HCO3 go the opposite direction of the pH? - Answer-this determines compensation. Once you determine acidosis or alkalosis and what system matches the pH then look at the other system. If the leftover system is out of range in the opposite column, then there is compensation by that system. Compensation - Answer-Opposite system used to achieve balance. Respiratory problem helped by metabolic system Metabolic problem helped by respiratory system Kidneys can act by redistributing HCO3 or elimination H+ Respiratory system primarily responds by increasing or decreasing RR. Hyperventilation eliminates CO2 and hypoventilation retains CO2
