Description

ABG Practice 1. pH 7.33, PaCO2 67 mmHg, PaO2 47 mmHg, HCO3 37 mEq/L Partially compensated Resp Acidosis 2. pH 7.18, PaCO2 38 mmHg, PaO2 70 mmHg, HCO3– 15 mEq/L Uncompensated Metabolic Acidosis 3. pH 7.31, PaCO2 48 mmHg, PaO2 78 mmHg, HCO3 15 mEq/L Partially Metabolic Acidosis 4. pH 7.60, PaCO2 30 mmHg, PaO2 60 mmHg, HCO3– 22 mEq/L Uncompensated Respiratory Alkalosis

5. pH 7.58, PaCO2 35 mmHg, PaO2 75 mmHg, HCO3– 50 mEq/L Uncompensated Metabolic Alkalosis

6. A client comes to the clinic with a blood sugar of 500, + ketones in urine, and complaining of polyuria. What Acid base imbalance would the nurse expect? How would this look on an ABG? a. DKA Metabolic Acidosis (low ph, low bicarb) potassium. Push Iv fluids may give sodium bicarb iv bag. 7. The nurse assesses a 72-year-old man in respiratory distress. Upon reviewing the ABG the nurse notes the client is in respiratory acidosis with a pH IS 7.32, PCO2 50, and PaO2 50. What interventions would the nurse complete next? What is the potential cause of this acid base imbalance? Respiratory Acidosis causes for hypoventilations pneumonia, copd, drug overdose, airway obstruction, ARDS. 8. A client comes to the clinic with RR of 36 and wheezing. What Acid base imbalance would the nurse expect? How would this look on an ABG? Resp. Alkalosis. Low co2, ph high

9. The nurse assesses a nasogastric tube to suction and find the client had 900 mL of green bile. What acid base imbalance is the client at risk for and how would it look on the ABG? Metabolic Alkalosis, stop suctioning of the NG but keep the head elevated just in case the patient starts to vomit

10. A patient is on a Venti Mask at 35%. Upon assessment, you see a RR of 26 and SaO2 of 89%. They have no past medical history and the physician has ordered titrate O2 to keep Sats > 92%. What is the nurse’s response? Why? Ensure patient is positioned correctly, head of the bed is elevated. May need to switch to another oxygen mask

11. A physician has prescribed oxygen at 30% (0.30 FiO2). What oxygen device(s) would fulfill this order? Veni mask, simple face mask, nasal canula. Cpap/BIpap can also be set to 30%. Also when a patient is ventilated .

ABG Practice

12. A client has an order to titrate O2 to maintain Sats>92%. The client’s respiratory assessment is RR 24, SaO2 98%, Lung sounds clear, no acute distress noted. What is the nurse’s response? Titrate O2 down, slowly remove patient off of oxygen

13. A client has an order to titrate O2 to maintain Sats>92%. Currently their SaO2 is 100% on 6LNC for the last few hours. What is the nurse’s best action? Titrate down

14. A client with COPD exacerbation due to pneumonia has a SaO2 80%. Which oxygen device would this client benefit from the most? (low flow) Ventri mask, nasal canula, cpap mask....
