Final answer:
Parenteral nutrition with greater than 10% dextrose requires a central venous catheter for administration due to the hypertonic nature of the solution. It necessitates careful monitoring of blood sugar levels and fluid and electrolyte balance.
Step-by-step explanation:
When you mentioned PN greater than 10% dextrose, you are referring to parenteral nutrition (PN) formulations with a high concentration of dextrose. For PN solutions with a dextrose concentration greater than 10%, it requires administration through a central venous catheter because these solutions are hypertonic and can cause irritation and thrombosis of peripheral veins. To ensure proper delivery and minimize complications, central venous access, such as through a peripherally inserted central catheter (PICC) or a tunneled catheter, is necessary.
Moreover, due to the high glucose content, there's also a need for careful monitoring of blood sugar levels, as well as close management of electrolytes and fluid balance. The use of a central line also allows for higher concentrations of nutrients to be delivered, which might be necessary for patients with substantial nutritional needs or fluid restrictions.
