ABGS AND RESPIRATORY EXAM SCRIPT
WITH VERIFIED QUESTIONS AND
ANSWERS
●● What is measured by ABGs?
Answer: pH, carbon dioxide (CO₂), bicarbonate (HCO₃), and oxygen
(O₂) levels in the blood.
●● What is the normal pH range of blood?
Answer: 7.35 to 7.45
●● What indicates acidosis in terms of pH?
Answer: pH < 7.35
●● What indicates alkalosis in terms of pH?
Answer: pH > 7.45
●● What is the normal range for CO₂ in the blood?
Answer: 35-45 mmHg
●● What CO₂ level indicates respiratory acidosis?
Answer: CO₂ > 45 mmHg
, ●● What CO₂ level indicates respiratory alkalosis?
Answer: CO₂ < 35 mmHg
●● What is the normal range for bicarbonate (HCO₃) in the blood?
Answer: 22-26 mEq/L
●● What HCO₃ level indicates metabolic acidosis?
Answer: HCO₃ < 22 mEq/L
●● What HCO₃ level indicates metabolic alkalosis?
Answer: HCO₃ > 26 mEq/L
●● What is the ROME method used for?
Answer: To determine if a problem is respiratory or metabolic based on
pH and CO₂ levels.
●● What does the acronym ROME stand for?
Answer: Respiratory Opposite, Metabolic Equal
●● What is the compensation mechanism for respiratory acidosis?
Answer: The kidneys excrete excess hydrogen and retain bicarbonate.
