NCLEX CRUSADE ACADEMY TEST - 8 ARTERIAL BLOOD GAS PRT 3

1. Which three values form the primary triad for ABG interpretation?. Oxygen, sodium, potassium. pH, PaCO2, HCO3. Hemoglobin, hematocrit, platelets. BUN, creatinine, glucose.

2. The first step in interpreting an ABG is to evaluate: PaCO2. HCO3. pH. Oxygen saturation.

3. What pH range is considered normal?. 6.8 - 7.0. 7.0 - 7.2. 7.35 - 7.45. 7.5 - 7.7.

4. A pH less than 7.35 indicates: Alkalosis. Acidosis. Compensation. Normal condition.

5. A PaCO2 greater than 45 mmHg indicates: Respiratory alkalosis. Respiratory acidosis. Metabolic alkalosis. Metabolic acidosis.

6. A PaCO2 less than 35 mmHg indicates: Respiratory alkalosis. Respiratory acidosis. Metabolic alkalosis. Metabolic acidosis.

7. The normal bicarbonate (HCO3) range is: 12 - 18 mEq/L. 18 - 20 mEq/L. 22 - 26 mEq/L. 30 - 35 mEq/L.

8. HCO3 values below 22 mEq/L indicate: Metabolic alkalosis. Respiratory alkalosis. Metabolic acidosis. Respiratory acidosis.

9. According to the R.O.M.E. method, respiratory disorders show: Equal movement of pH and CO2. Opposite movement of pH and CO2. Equal movement of pH and HCO3. Opposite movement of HCO3 and CO2.

10. According to the R.O.M.E. method, metabolic disorders show: Opposite relationship. Equal movement of pH and HCO3. CO2 changes only. No pH change.

11. A patient with high pH and low CO2 is experiencing: Respiratory alkalosis. Respiratory acidosis. Metabolic acidosis. Metabolic alkalosis.

12. A patient with low pH and high CO2 is experiencing: Respiratory alkalosis. Respiratory acidosis. Metabolic alkalosis. Metabolic acidosis.

13. When pH and HCO3 decrease together, the condition is: Metabolic acidosis. Respiratory acidosis. Metabolic alkalosis. Respiratory alkalosis.

14. When pH and HCO3 increase together, the condition is: Respiratory alkalosis. Metabolic alkalosis. Respiratory acidosis. Metabolic acidosis.

15. Which system primarily controls PaCO2 levels?. Kidneys. Lungs. Liver. Pancreas.

16. Which organ regulates bicarbonate levels?. Kidneys. Heart. Liver. Brain.

17. In ABG interpretation, the component that determines the primary disorder is: Oxygen. The value matching the pH change. The highest number. Sodium level.

18. If both respiratory and metabolic components are abnormal, this suggests: Compensation. Dehydration. Infection. Hypoxia.

19. In respiratory alkalosis with metabolic compensation, which value compensates?. PaCO2. HCO3. pH. Oxygen.

20. Which principle helps identify the primary ABG disorder?. Identify the largest number. Match the abnormal value with the pH. Ignore bicarbonate. Only evaluate oxygen.

21. Hyperventilation usually causes: Respiratory acidosis. Respiratory alkalosis. Metabolic acidosis. Metabolic alkalosis.

22. Hypoventilation usually causes: Respiratory acidosis. Respiratory alkalosis. Metabolic acidosis. Metabolic alkalosis.

23. If pH is normal but CO2 and HCO3 are abnormal, this indicates: Mixed disorder. Compensation. Infection. Hypoxia.

24. Which approach helps solve complex ABG questions beyond ROME?. Memorizing numbers only. Ignoring CO2. Using logical frameworks such as tic-tac-toe method. Guessing the diagnosis.

25. The most important skill in ABG interpretation is: Memorization only. Critical thinking and logical analysis. Ignoring patient symptoms. Guessing patterns.
