What is the final step in ordering a TPN?

The final step in ordering a Total Parenteral Nutrition (TPN) is to include all relevant information and lab orders, as this ensures the TPN is tailored to the specific needs of the patient. This step involves compiling necessary data such as the patient's nutritional requirements, medical history, and any laboratory results that indicate the patient's current health status. This comprehensive approach helps healthcare providers to create a well-balanced TPN formulation that addresses the individual needs of the patient, including macronutrient ratios and fluid volume.

Incorporating this final information is critical because it allows for precise adjustments based on the patient's ongoing health status and nutritional needs, which can change based on lab results or other clinical information. Therefore, this meticulous documentation is essential to the safe and effective administration of TPN.
