• 6.9
• 7.8
• 7.6

The nurse is caring for a client with a nasogastric tube that is attached to low suction. The nurse monitors the client, knowing that the client is at risk for which acid-base disorder?

• Metabolic acidosis 
•  Metabolic alkalosis 
• Respiratory acidosis
• Respiratory alkalosis 

The normal pH range for blood is:

• 7.0 - 7.25
• 7.30 - 7.40
• 7.35 - 7.45
• 7.45 - 7.55

The respiratory system compensates for changes in the pH level by responding to changes in the levels of:

• CO2
•  H2O
• H2CO3
• HCO3

The kidneys compensate for acid-base imbalances by excreting or retaining:

• Hydrogen ions
• Carbonic acid
• Sodium bicarbonate
• Water

A patient with a prolonged episode of nausea, vomiting and diarrhea has an ABG ordered on admission. You might expect the results to show:

• Metabolic acidosis
• Metabolic alkalosis
• Respiratory acidosis
• Respiratory alkalosis

Which of the following may be a reason to order an ABG on a patient?

• The patient suddenly develops shortness of breath
  
• An asthmatic is starting to show signs of tiring
• A diabetic has developed Kussmaul respirations
• All of the above

You are reviewing the results of an ABG. When the pH and the PaCO2 values are moving in opposite directions, the primary problem is: 

• Respiratory
• Renal
• Metabolic
• Compensation

When an acid-base imbalance is caused by a metabolic disturbance, the pH and the HCO3 will move:

• In opposite directions
• Totally independent of each other 
• In the same direction

pH 7.38 pCO2 38 HCO3 24

• Respiratory alkalosis
• Normal
• Metabolic alkalosis
• None of the above
