Question

what are the most common electrolytes in the plasma? (select all that apply)
check all that apply
□ sodium
□ phosphate
□ chloride
□ bicarbonate

Explanation:

To determine the most common electrolytes in plasma, we rely on physiological knowledge. Plasma electrolytes include sodium (the most abundant cation), chloride (a major anion), bicarbonate (important for acid - base balance), and phosphate (though less abundant than the first three, still a common plasma electrolyte). So we need to select all these options.

Answer:

A. Sodium, B. Phosphate, C. Chloride, D. Bicarbonate (Here we assume the options are labeled A - D in order. If the original options had no labels, we can also describe it as "Sodium, Phosphate, Chloride, and Bicarbonate" as the correct selections.)
