Lactated Ringers contains what electrolyte?

Lactated Ringers contains what electrolyte?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Answer: (B)

Lactated Ringer's is a balanced IV solution designed to replace fluids and electrolytes. It contains multiple electrolytes that resemble plasma, including sodium, chloride, potassium, and calcium, along with lactate that acts as a bicarbonate precursor. Among common choices, potassium is an electrolyte that lactated Ringer's contains. This inclusion supports cellular function, nerve signaling, and proper cardiac conduction, which is why LR is often used in fluid resuscitation. It’s also useful to note that while potassium is present, so are sodium and calcium, but magnesium is not part of this solution.
