Fun Quiz: Acid Base Balance

#1. The patient loses consciousness and the STAT ABGs reveal pH 7.61, PCO2 22 mmHg, and HCO3 25 mEq/L. What is the ABG interpretation based on the findings?

Metabolic Acidosis, Uncompensated

Respiratory Alkalosis, Uncompensated

Respiratory Alkalosis, Partially Compensated

Metabolic Alkalosis, Partially Compensated

#2. A mountaineer attempts an assault on a high mountain in the Andes and reaches an altitude of 5000 meters (16,400 ft) above sea level. What will happen to his arterial PCO2 and pH?

Both will be higher than normal due to physical exertion

Both will be lower than normal

The pH will fall and PCO2 will rise

The pH will rise and PCO2 will fall

#3. In acid-base balance, the normal plasma PCO2 and bicarbonate levels are disturbed. Match the changes in this parameter with the disorders in the given choices: Increased plasma bicarbonate (HCO3-)

Metabolic Acidosis

Respiratory Acidosis

Metabolic Alkalosis

Respiratory Alkalosis

#4. Match the acid-base status of the following blood samples to the disorders in the given choices. (PCO2 values are in mm Hg and bicarbonate values in mmol/l). pH 7.64, PCO2 25, HCO3- 19

Metabolic Alkalosis, Partially Compensated

Respiratory Alkalosis, Uncompensated

Respiratory Acidosis, Uncompensated

Respiratory Alkalosis, Partially Compensated

#5. Dave, a 6-year-old boy, was rushed to the hospital following her mother’s complaint that her son has been vomiting, nauseated and has overall weakness. After a series of tests, the nurse notes the laboratory results: potassium: 2.9 mEq. Which primary acid-base imbalance is this boy at risk for if medical intervention is not carried out?

Metabolic Alkalosis

Metabolic Acidosis

Respiratory Alkalosis

Respiratory Acidosis

#6. The results from the ABGs show pH 7.57, PCO2 37 mmHg and HCO3 30 mEq/L. What is your assessment?

Respiratory Alkalosis, Uncompensated

Metabolic Alkalosis, Uncompensated

Metabolic Acidosis, Uncompensated

Metabolic Alkalosis, Partially Compensated

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

Gallbladder and Appendix

Lungs and Spleen

Heart and Liver

Kidney and Lungs

#8. Match the acid-base status of the following blood samples to the disorders in the given choices. (PaCO2 values are in mm Hg and bicarbonate values in mmol/l). pH 7.34, PCO2 24, HCO3- 20

Respiratory Acidosis, Partially Compensated

Metabolic Acidosis, Partially Compensated

Metabolic Acidosis, Uncompensated

Metabolic Alkalosis, Partially Compensated

#9. An elderly client was admitted to hospital in a coma. Analysis of the arterial blood gave the following values: PCO2 16 mm Hg, HCO3 5 mmol/L and pH 7.1. As a lab professional, you know that the normal value for HCO3 is:

29 mmol/L

24 mmol/L

20 mmol/L

31 mmol/L

#10. Measurement of arterial blood gas reveals pH 7.6, PO2 120 mm Hg, PCO2 31 mm Hg, and HCO3 25 mmol/L. What does this mean?

Metabolic Alkalosis, Uncompensated

Metabolic Alkalosis, Partially Compensated

Respiratory Acidosis, Partially Compensated

Respiratory Alkalosis, Uncompensated
