ms - ABG interpretation correct answers 100% 2023ABG is useful for: - correct answer *For monitoring treatment, adjusting oxygen settings and evaluating client response -Partial pressure of oxygen (PaO2). -Partial pressure of carbon dioxide (PaCO2). -pH. -Bicarbonate (HCO3). -Oxygen saturation (O2Sat) pH - correct answer *pH - Measurement of acidity or alkalinity, based on the hydrogen (H+) ions present. -The normal range is 7.35 to 7.45 -Remember: pH greater than 7.45 = alkalosis pH less than 7.35 = acidosis PO2 - correct answer The partial pressure of oxygen that is dissolved in arterial blood. - The normal range is 80 to 100 mm Hg. SaO2 - correct answer The arterial oxygen saturation. - The normal range is 95% to 100%. pCO2 - correct answer *The amount of carbon dioxide dissolved in arterial blood. - The normal range is 35 to 45 mm Hg. - Remember: PCO2 greater than 45 = acidosis pCO2 less than 35 = alkalosis HCO3 - correct answer *The calculated value of the amount of bicarbonate in the bloodstream. - The normal range is 22 to 26 mEq/liter - Remember: HCO3 greater than 26 = alkalosis HCO3 less than 22 = acidosis B.E. - correct answer *The base excess indicates the amount of excess or insufficient level of bicarbonate in the system. - The normal range is -2 to +2 mEq/liter. - Remember: A negative base excess indicates a base deficit in the blood. Normal range: pO2 - correct answer 80-100 Normal range: pCO2 - correct answer 35-45 Normal range: HC03 - correct answer 22-26 Rates of correction - correct answer -Buffers function almost instantaneously -Respiratory mechanisms take several minutes to hours -Renal mechanisms may take several hours to days The Bodys' Buffer system includes: - correct answer -Bllood (protteiin) -Lungs (Co2) -Kiidneys(HCO3) The arterial blood gas is used to evaluate ___. - correct answer Both acid-base balance and oxygenation, each representing separate conditions. Acid-base evaluation requires ___. - correct answer A focus on three of the reported components: pH, PaCO2 and HCO3. Steps to an Arterial Blood Gas Interpretation: Step 1 - correct answer *Step one: Identify whether the pH, pCO2 and HCO3 are abnormal. For each component, label it as "normal", "acid" or "alkaline". * The two matching values determine what the problem is. Steps to an Arterial Blood Gas Interpretation: Step 1 - correct answer *If the ABG results are abnormal, determine if the abnormality is due to the kidneys (metabolic) or the lungs (respiratory). *Match the two abnormalities: Respiratory (lung problem) + Acidosis = Respiratory Acidosis.
