From 5% dextrose in water, what primary benefit does the patient receive?

The primary benefit a patient receives from 5% dextrose in water is calories or fuel. Dextrose, which is a form of glucose, is a simple carbohydrate that the body can easily metabolize for energy. This is crucial, especially in a clinical setting, where patients may require additional calories for recovery, especially if they are unable to consume food orally due to various medical conditions.

When administered intravenously, the dextrose in the solution provides a readily available source of energy to support metabolic processes, maintain blood glucose levels, and prevent hypoglycemia, particularly in patients who are malnourished or in a catabolic state.

Other options such as electrolytes, protein, or vitamins are not present in significant quantities in 5% dextrose in water. While some solutions used in nutritional support might include these nutrients, 5% dextrose in water is primarily intended for caloric support. This distinction helps in understanding its specific role in nutritional therapy.
