In correcting fluids and electrolytes, which should be addressed first?

• A. Volume
• B. pH
• C. K, Ca, Mg
• D. Na, Cl

Answer: (A)

Restoring intravascular volume is the priority. When a patient is hypovolemic, tissues aren’t being adequately perfused, so the first step is to reestablish circulating volume with fluids to improve preload, cardiac output, and kidney perfusion. Once perfusion and hemodynamics are stabilized, you can safely assess and correct electrolyte disturbances (potassium, calcium, magnesium, sodium, chloride) and any acid-base issues. Correcting electrolytes or pH before volume status is restored can worsen instability and lead to harmful shifts as the body redistributes fluids and electrolytes. So, volume status comes first, then focused electrolyte and acid-base corrections.
