Parenteral nutrition and refeeding

Definition
A dangerous metabolic shift occurring when a severely malnourished client receives aggressive nutrition, causing rapid intracellular movements of phosphorus, potassium, and magnesium.
Parenteral nutrition and refeeding in plain English
The immediate threat to life is fatal cardiac failure; nursing surveillance must focus on precipitously dropping serum phosphorus levels during the first 24 to 48 hours of feeding. The main trap is focusing on caloric intake goals and infusion pump mechanics while failing to recognize the specific cue of hypophosphatemia as a refeeding signal.
