Fun Quiz: Acid Base Balance

#1. Measurement of arterial blood gas shows pH 7.3, PCO2 68 mm Hg, HCO3 28 mmol/L, and PO2 60 mm Hg. How would you interpret this?

Metabolic Acidosis, Partially Compensated

Metabolic Alkalosis, Uncompensated

Respiratory Acidosis, Uncompensated

Respiratory Acidosis, Partially Compensated

#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 7.6, PCO2 53, HCO3- 38

Respiratory Alkalosis, Fully Compensated

Metabolic Alkalosis, Fully Compensated

Respiratory Acidosis, Partially Compensated

Metabolic Alkalosis, Partially Compensated

#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: High plasma PCO2

Metabolic Acidosis

Metabolic Alkalosis

Respiratory Acidosis

Respiratory Alkalosis

#4. 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 7.17, PCO2 48, HCO3- 36

Respiratory Acidosis, Uncompensated

Respiratory Alkalosis, Partially Compensated

Respiratory Acidosis, Partially Compensated

Metabolic Acidosis, Partially Compensated

#5. Arterial blood gas (ABG) measurement will give the information needed to determine if the primary disturbance of acid-base balance is respiratory or metabolic in nature

Both Bicarbonate Excess and Deficit Only

False

True

Both Carbonic Acid Excess and Deficit Only

#6. 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:

24 mmol/L

31 mmol/L

20 mmol/L

29 mmol/L

#7. 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 lower than normal

The pH will rise and PCO2 will fall

Both will be higher than normal due to physical exertion

The pH will fall and PCO2 will rise

#8. Measurement of arterial blood gas shows pH 7.0, PaO2 90 mm Hg, PaCO2 23 mm Hg, and HCO3 12 mmol/L; other results are Na+ 126 mmol/L, K+ 5 mmol/L, and Cl- 95 mmol/L. What is your assessment?

Respiratory Acidosis, Uncompensated

Respiratory Acidosis, Partially Compensated

Metabolic Alkalosis, Uncompensated

Metabolic Acidosis, Partially, Compensated

#9. The major effect of acidosis is overexcitement of the central nervous system.

Maybe

True

False

Both Acidosis and Alkalosis result in overexcitement of the central nervous system

#10. Acids have no hydrogen ions and are able to bind in a solution

Acids and bases have nothing to do with hydrogen ions.

True

False

Acid is a substance that is not capable of donating hydrogen ions
