Dextrose and Water (D5W) is used for which purpose?

• A. Fluid used as a calorie replacement or when glucose is needed for a hypoglycemic patient
• B. Antiseptic irrigation solution
• C. Electrolyte replacement only
• D. Pain management during IV therapy

Answer: (A)

D5W is used primarily as a source of calories and glucose. The dextrose provides a quick energy supply, so it’s appropriate when a patient needs calories or is hypoglycemic and requires glucose. After the dextrose is metabolized, what remains is free water, which helps with hydration but does not replace electrolytes. Because of that, D5W isn’t the go-to for electrolyte replacement, nor is it an antiseptic irrigation solution or a pain-management agent. So the best use is as a fluid that delivers calories and glucose to treat or prevent hypoglycemia.
