What is the component measured in an Electrolyte Panel?

The component measured in an Electrolyte Panel includes Sodium, Calcium, Chloride, and CO2 (bicarbonate). This panel is primarily used to evaluate a patient's electrolyte balance and acid-base status, which is crucial for many physiological functions. Sodium and chloride are prominent electrolytes that help regulate fluid balance and are vital for the proper function of muscles and nerves. Bicarbonate plays an important role in maintaining the body's pH level, while calcium is essential for bone health and various metabolic processes.

In summary, the Electrolyte Panel is specifically designed to assess these key components, making option A the correct choice for identifying the components routinely measured in such a panel.
