What should be administered if Total Parenteral Nutrition (TPN) is unavailable to prevent hypoglycemia?

When Total Parenteral Nutrition (TPN) is unavailable, it is crucial to prevent hypoglycemia, particularly in patients who have been receiving TPN, as their bodies may become dependent on the glucose provided by the nutritional solution. Administering Dextrose 10% in water is appropriate because it provides an immediate source of glucose, helping to stabilize blood sugar levels effectively.

Dextrose solutions are designed to replenish glucose rapidly and can help avert hypoglycemic episodes that could result from the sudden cessation of TPN. The concentration of dextrose at 10% is sufficient for maintaining glucose levels while awaiting the resumption of TPN or until alternative nutritional support is arranged.

In contrast, normal saline, glucose tablets, and Lactated Ringer's solution do not provide sufficient or immediate glucose to prevent hypoglycemia. Normal saline is primarily an electrolyte solution and does not contain glucose. Glucose tablets are not typically administered intravenously and are designed for oral consumption, where they may not be as effective in rapidly preventing hypoglycemia, especially in patients who may have difficulty swallowing. Lactated Ringer's solution contains electrolytes and is used for hydration but does not contain glucose, thus failing to address the immediate risk of low blood sugar
