Which of the following parameters is measured in an Arterial Blood Gas (ABG) test?
- A.
  
  Blood sugar levels
- B.
  
  Carbon dioxide levels
- C.
  
  Hemoglobin concentration
- D.
  
  Red blood cell count
Correct Answer
B. Carbon dioxide levels

Explanation
An Arterial Blood Gas (ABG) test measures the levels of oxygen (O₂), carbon dioxide (CO₂), and the blood’s pH (acidity or alkalinity) in arterial blood. The test is commonly used to assess how well the lungs are functioning in oxygenating the blood and removing CO₂. ABG also measures bicarbonate (HCO₃⁻) and the partial pressure of oxygen (PaO₂) and carbon dioxide (PaCO₂). Blood sugar, hemoglobin concentration, and red blood cell count are not assessed in an ABG test; they are measured through other specific blood tests.
