Fun Quiz: Acid Base Balance

#1. 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:

31 mmol/L

20 mmol/L

24 mmol/L

29 mmol/L

#2. 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 Acidosis, Uncompensated

Respiratory Alkalosis, Partially Compensated

Respiratory Alkalosis, Uncompensated

#3. 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?

The pH will fall and PCO2 will rise

Both will be higher than normal due to physical exertion

Both will be lower than normal

The pH will rise and PCO2 will fall

#4. 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 Alkalosis

Metabolic Acidosis

Respiratory Alkalosis

Respiratory Acidosis

#5. Measurement of arterial blood gas shows pH 7.0, PO2 90 mm Hg, PaCO2 22 mm Hg, and HCO3 14 mmol/L; other results are Na+ 120 mmol/L, K+ 2.5 mmol/L, and Cl- 95 mmol/L. Which do you know is within the normal value for PCO2?

22 mmHg

36 mmHg

50 mmHg

48 mmHg

#6. 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 7.45, PCO2 50, HCO3- 30

Respiratory Acidosis, Partially Compensated

Metabolic Alkalosis, Partially Compensated

Metabolic Alkalosis, Fully Compensated

Respiratory Alkalosis, Fully Compensated

#7. 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: Decreased plasma bicarbonate (HCO3-)

Metabolic Acidosis

Respiratory Acidosis

Metabolic Alkalosis
