ABG INTERPRETING

Measurement of arterial blood gas shows pH 7.3, PaCO2 68 mm Hg, HCO3 28 mmol/L, and PaO2 60 mm Hg. How would you interpret this?

• Respiratory Acidosis, Uncompensated

• Respiratory Acidosis, Partially Compensated

• Metabolic Alkalosis, Uncompensated

• Metabolic Acidosis, Partially Compensated

Measurement of arterial blood gas shows pH 7.0, PaO2 90 mm Hg, PaCO2 23 mm Hg, and HCO3 12 mmol/L; What is your assessment?

• Respiratory Acidosis, Uncompensated

• Respiratory Acidosis, Partially Compensated

• Metabolic Alkalosis, Uncompensated

• Metabolic Acidosis, Partially, Compensated

Measurement of arterial blood gas reveals pH 7.6, PaO2 120 mm Hg, PaCO2 31 mm Hg, and HCO3 25 mmol/L.

• Respiratory Alkalosis, Uncompensated

• Respiratory Acidosis, Partially Compensated

• Metabolic Alkalosis, Uncompensated

• Metabolic Alkalosis, Partially Compensated

Measurement of arterial blood gas shows pH 7.5, PaO2 85 mm Hg, PaCO2 40 mm Hg, and HCO3 34 mmol/L. What acid-base disorder is shown?

• Respiratory Acidosis, Uncompensated

What two organs in the body serve as a compensatory function to maintain acid-base balance?

• Kidneys and Lungs

• Lungs and Spleen

• Heart and Liver

• Gallbladder and Appendix

In a patient undergoing surgery, it was vital to aspirate the contents of the upper gastrointestinal tract. After the operation, the following values were acquired from an arterial blood sample: pH 7.55, PCO2 52 mm Hg and HCO3- 40 mmol/l. What is the underlying disorder?

• Respiratory Acidosis

• Respiratory Alkalosis

• Metabolic Acidosis

• Metabolic Alkalosis

Client Z is admitted to the hospital and is to undergo brain surgery. The client is very anxious and scared of the upcoming surgery. He begins to hyperventilate and becomes very dizzy. The client loses consciousness and the STAT ABGs reveal pH 7.61, PaCO2 22 mmHg, and HCO3 25 mEq/L. What is the ABG interpretation based on the findings?

• Metabolic Acidosis, Uncompensated

• Respiratory Alkalosis, Partially Compensated

• Respiratory Alkalosis, Uncompensated

• Metabolic Alkalosis, Partially Compensated
