Which set of labs does ASPEN recommend for weekly monitoring until the home PN patient is stable?

• A. Serum glucose; Electrolytes; BUN; Creatinine; Magnesium; Phosphorus
• B. Serum glucose; Electrolytes; BUN; Creatinine
• C. Electrolytes; Magnesium; Phosphorus
• D. Serum glucose; BUN; Magnesium; Phosphorus

Answer: (A)

The main concept is that when starting or adjusting home parenteral nutrition, the focus is on rapidly detecting and correcting metabolic and organ-function imbalances so the patient remains safe and stable. Weekly checks of serum glucose, electrolytes, BUN, creatinine, magnesium, and phosphorus provide a comprehensive view of how the PN is affecting metabolism, fluid balance, kidney function, and essential minerals. Serum glucose is monitored because the IV PN solution delivers a continuous glucose load; tracking it helps identify hyperglycemia or hypoglycemia and guides adjustments to PN rate or insulin if needed. Electrolytes are checked since PN supplies electrolytes and shifts in fluids or metabolism can quickly cause imbalances in sodium, potassium, chloride, bicarbonate, calcium, magnesium, and phosphorus, all of which influence fluid balance, nerve and muscle function, and acid-base status. BUN and creatinine assess renal function and protein metabolism; they help detect dehydration, overhydration, or excessive protein load and indicate whether the kidneys are handling the PN appropriately. Magnesium and phosphorus are critical minerals often affected by PN and shifts during refeeding; deficiencies can cause significant symptoms and complications, so monitoring these ensures timely supplementation and dose adjustments. Other options omit one or more of these essential areas (glycemic control, renal function, or mineral status), making them less comprehensive for ensuring safe, stable PN therapy.
