Which statement about Lactated Ringer's solution is true?

Lactated Ringer's solution is indeed closest in electrolyte composition to normal blood serum compared to many other intravenous fluids. This isotonic solution contains sodium, potassium, calcium, bicarbonate, and chloride, closely mimicking the electrolyte profile found in human plasma. This makes it particularly useful for fluid resuscitation and is often used in surgical settings or trauma situations to restore fluid and electrolyte balance effectively.

The other options do not accurately describe Lactated Ringer's solution. For instance, while some IV solutions contain glucose, Lactated Ringer's does not have a high concentration of glucose; it is primarily designed for electrolyte replenishment rather than providing energy through sugar. Moreover, it is not contraindicated for all patients, as it can be beneficial for many, although there are specific situations where its use may need to be limited, such as in patients with specific renal conditions or those needing to restrict potassium. Lastly, the storage requirements for Lactated Ringer's solution typically recommend that it be stored in a cool place rather than strictly at room temperature, allowing for flexibility in storage practices.

Overall, the composition of Lactated Ringer's solution makes it a valuable choice for maintaining fluid and electrolyte balance in clinical settings.
