In managing total parenteral nutrition (TPN), what is an important nursing consideration?

• A. All intravascular delivery system components up to the hub are changed weekly to prevent infection.
• B. Serum glucose levels and weights are checked weekly.
• C. TPN requires daily temperatures, as infection is the most common complication of TPN.
• D. Speeding up or slowing the infusion rate is contraindicated.

Answer: (D)

The important nursing consideration is maintaining the infusion rate exactly as prescribed. The amount and speed at which TPN is delivered determine how quickly the nutrients, glucose, and electrolytes enter the bloodstream. If the rate is increased or decreased without an explicit order, it can cause dangerous glucose swings, electrolyte imbalances, or fluid shifts and undermine the prescribed nutrition plan. Therefore, altering the infusion rate is contraindicated unless guided by a clinician or protocol with appropriate monitoring. While monitoring is still essential—glucose levels and weight, signs of infection, and catheter care are all important—the rate itself must stay aligned with the order. Practices like changing all tubing weekly or requiring daily temperatures aren’t standard or primary requirements for TPN management.
