Module 9 Review

What is the term for direct measurements of fluids or tissue, like Arterial Blood Gas (ABG) samples, that must be taken from the body?

• Noninvasive analysis
• Laboratory analysis
• Monitoring
• Continuous oximetry

What is considered the gold standard for assessing gas exchange in the cardiopulmonary system?

• ABG samples
• Continuous Pulse Oximetry
• Capnometry
• Transcutaneous Oxygen Monitoring (PtcCO2)

Why is the radial site preferred for ABG punctures?

• No large veins are near
• Collateral circulation usually exists via ulnar artery
• It is near the surface and easy to palpate/stabilize
• It is the largest artery in the human body

• Catastrophic organ failure

How long should you wait before drawing an ABG on a COPD patient after changing their FIO2?

• 1 hour
• 30 minutes
• 5 to 10 minutes
• Draw the ABG immediately

How would you define a PaO2 of 45 mm Hg?

• Normal
• Mild hypoxemia
• Moderate hypoxemia
• Severe hypoxemia

Interpret the following ABG: pH: 7.32 PaCO2: 50 HCO3: 28

• Partially Compensated Respiratory Acidosis
• Uncompensated Respiratory Acidosis
• Compensated Metabolic Acidosis
• Uncompensated Respiratory Alkalosis

Interpret the following ABG: pH: 7.24 PaCO2: 36 HCO3: 12

• Uncompensated Metabolic Acidosis
• Compensated Respiratory Acidosis
• Uncompensated Respiratory Acidosis
• Compensated Metabolic Acidosis

Prior to obtaining a capillary blood gas sample, what temperature should the skin be warmed to?

• 37 degrees Celsius
• 37 degrees Fahrenheit
• 42 degrees Celsius
• 42 degrees Fahrenheit

Which values are directly measured in an ABG sample?

• pH
• PCO2
