• 7.35 - 7.45

• 7.25 - 7.35

• 7.55 - 7.65

Which component is controlled by the respiratory system?

• SaO2

• HCO3-

• PaO2

• PaCO2

What characterizes respiratory acidosis?

• Decreased pH and decreased HCO3-

• Increased pH and decreased PaCO2

• Increased pH and increased HCO3-

• Decreased pH and increased PaCO2

What is the formula for calculating the anion gap?

• Anion Gap = [Na+] - ([Cl-] + [HCO3-])

• Anion Gap = [Cl-] - ([Na+] + [HCO3-])

• Anion Gap = [HCO3-] - ([Na+] + [Cl-])

• Anion Gap = [Na+] + ([Cl-] + [HCO3-])

Which condition is an example of metabolic acidosis?

• Anxiety

• Vomiting

• Diabetic ketoacidosis

• High altitude

What does a low PaO2 indicate?

• Hypercapnia

• Hypoxemia

• 22 - 26 mEq/L

• 24 - 28 mEq/L

• 20 - 24 mEq/L

• 26 - 30 mEq/L

Which of the following is a compensatory mechanism for acid-base balance?

• Altered respiratory rate

• Increased blood pressure

• Decreased oxygen saturation

• Increased heart rate

What is a limitation of ABG analysis?

• It provides a comprehensive view of long-term health

• It is a snapshot of a patient's status at a single point in time

• It requires a venous blood sample

• It is less invasive than other tests
