#4. A company driver is found at the scene of an automobile accident in a state of emotional distress. He tells the paramedics that he feels dizzy, tingling in his fingertips, and does not remember what happened to his car. Respiratory rate is rapid at 34/minute. Which primary acid-base disturbance is the young man at risk for if medical attention is not provided?

Metabolic Alkalosis

Metabolic Acidosis

Respiratory Alkalosis

Respiratory Acidosis

#5. 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?

Metabolic Alkalosis

Metabolic Acidosis

Respiratory Acidosis

Respiratory Alkalosis

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

Lungs and Spleen

Kidney and Lungs

Heart and Liver

Gallbladder and Appendix

#7. 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

#8. An old beggar was admitted to the emergency department due to shortness of breath, fever, and a productive cough. Upon examination, crackles and wheezes are noted in the lower lobes; he appears to be tachycardic and has a bounding pulse. Measurement of arterial blood gas shows pH 7.2, PaCO2 66 mm Hg, HCO3 27 mmol/L, and PaO2 65 mm Hg. As an experience lab tech, you know that the normal value for pH is:

7.40

7.30

7.20

7.50

#9. 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 7.55, PCO2 25, HCO3- 22

Respiratory Alkalosis, Uncompensated

Metabolic Alkalosis, Partially Compensated

Metabolic Acidosis, Uncompensated

Respiratory Acidosis, Partially Compensated

#10. Measurement of arterial blood gas shows pH 7.10, PCO2 70 mm Hg, and HCO3 24 mEq/L. What does this mean?

Metabolic Acidosis, Uncompensated

Respiratory Acidosis, Uncompensated

Respiratory Alkalosis, Partially Compensated

Metabolic Alkalosis, Partially Compensated
