What solution provides both electrolytes and calories for IV fluid therapy?

The solution that provides both electrolytes and calories for IV fluid therapy is Lactated Ringer's solution. This solution is specifically formulated to contain a balanced composition of electrolytes, including sodium, potassium, calcium, and lactate, making it effective for replenishing electrolytes in patients who may be dehydrated or suffering from electrolyte imbalances.

In addition to electrolytes, Lactated Ringer's solution also helps in providing calories through the lactate component, which is metabolized to bicarbonate in the liver, potentially providing additional energy. As a versatile fluid, it is often used in surgical patients, trauma cases, and those experiencing acute gastrointestinal fluid loss.

While Normal Saline is a basic electrolyte solution, it does not provide any calories since it contains only sodium and chloride without any glucose or other caloric components. Dextrose 5% in Water does provide calories due to the dextrose content but lacks significant electrolyte balance. Hypertonic Saline, although containing sodium chloride, is primarily used to increase serum sodium levels in specific clinical scenarios and does not contribute calories. Therefore, Lactated Ringer's is the most suitable choice for a solution that meets both criteria of providing electrolytes and calories.
