can't ingest, absorb, or digest essential nutrients via the GI tract
TPN Nutrient Components - correct answer amino acids, glucose, fat emulsion,
vitamins, electrolytes, minerals, trace elements, water, glucose concentration (10% for adults, 15-25%
depending on condition of pt)

24 hours; TPN, lipids, and tubing changed every 24 hours; TPN is administered with in line micron filter
(special IV tubing), no meds are added to TPN solution bags; infused as a closed system and no piggy
backing; kept refrigerated until 30 min prior to being infused
If TPN infusion unavailable - correct answer IV solution of Dextrose 10% and water
(D10W) until TPN available, to prevent rebound hypoglycemia
Lipids - correct answer can be given as separate infusion and don't require
refrigeration, may be administered via peripheral IV catheter, do not require filtered IV tubing, no filter
Clinical Do's - correct answer check bag against order for correct pt name, formula,
components, and expiration date; keep refrigerated until ready to infuse, use strict aseptic technique,
change solution and IV tubing every 24 hours, BG is monitored (at least 4x a day) and insulin
administered per protocol; monitor for signs of hyperglycemia; monitor central access site for signs of
infection; monitor pt for signs & symptoms of infection/sepsis
