Lactated Ringers contains which electrolytes?

Lactated Ringers contains which electrolytes?

• A. Sodium, Chloride, Calcium, and Potassium
• B. Sodium and Chloride only
• C. Sodium, Chloride, and Magnesium
• D. Sodium, Potassium, and Bicarbonate

Answer: (A)

Lactated Ringer's is a balanced crystalloid whose electrolyte content mirrors plasma more closely than normal saline. It contains sodium and chloride, plus potassium and calcium. It does not contain magnesium, and there isn’t a free bicarbonate ion in the solution—the lactate acts as a buffer and is metabolized to bicarbonate in the body. So the electrolytes present are sodium, chloride, potassium, and calcium. The other options omit one of these ions or include an ion not found in LR.
