Lactated Ringers is classified as which type of IV fluid?

Explanation:
Lactated Ringer's is a crystalloid IV fluid. Crystalloids are solutions with small, water-soluble molecules that freely diffuse across capillary walls, so they distribute quickly between the intravascular and interstitial spaces. This means they provide volume expansion but less sustained intravascular volume per milliliter than colloids. Lactated Ringer's contains sodium, chloride, potassium, calcium, and lactate, with osmolality close to plasma. The lactate is metabolized by the liver to bicarbonate, helping buffer acidosis. It is not a colloid, which would have large molecules that stay in the intravascular space longer, nor a blood product or a lipid emulsion.
