Understanding ABG Interpretation Quiz

What does ABG stand for in clinical medicine?

• Arterial Blood Gas

• Arterial Blood Glucose

• Alveolar Blood Gas

• Arterial Base Gap

What is the normal range for arterial blood pH?

• 7.25 – 7.35

• 7.35 – 7.45

• 7.45 – 7.55

• 7.30 – 7.40

• 25 – 35 mmHg

• 55 – 65 mmHg

• 35 – 45 mmHg

• 45 – 55 mmHg

Which organ system is primarily responsible for the metabolic component of acid-base balance as reflected in ABG results?

• Lungs

• Kidneys

• Liver

• Heart

• 10 – 15 mEq/L

• 16 – 20 mEq/L

• 22 – 26 mEq/L

• 28 – 32 mEq/L

• Metabolic acidosis

• Respiratory alkalosis

• Respiratory acidosis

• Metabolic alkalosis

• Primary respiratory alkalosis with appropriate metabolic compensation

• Primary metabolic acidosis with appropriate respiratory compensation

• Primary metabolic acidosis with inadequate respiratory compensation, suggesting a concurrent respiratory alkalosis

• Mixed metabolic and respiratory acidosis

• Metabolic alkalosis; administer sodium bicarbonate

• Respiratory alkalosis due to hyperventilation; increase the ventilator's tidal volume

• Respiratory alkalosis due to hyperventilation; decrease the ventilator's respiratory rate or tidal volume

• Compensated metabolic alkalosis; no ventilator changes needed

• Uncompensated respiratory acidosis

• Metabolic alkalosis with respiratory compensation

• Compensated respiratory acidosis, consistent with chronic CO2 retention

• Mixed metabolic alkalosis and respiratory acidosis requiring immediate intubation

• Uncompensated metabolic alkalosis with no respiratory response

• Metabolic alkalosis with appropriate respiratory compensation, likely due to loss of gastric acid from vomiting

• Respiratory acidosis with metabolic compensation

• Mixed metabolic alkalosis and respiratory acidosis requiring bicarbonate correction
