Which test or tests are included in the weekly lab monitoring for home PN?

• A. All of the above
• B. Serum glucose
• C. Creatinine
• D. Phosphorus

Answer: (A)

Weekly lab monitoring during home PN focuses on how the patient is handling the glucose load, kidney function, and phosphorus balance, because these areas directly influence safety and PN effectiveness. Serum glucose is tracked because PN solutions deliver a high dextrose load; monitoring helps catch hyperglycemia or hypoglycemia and guides adjustments to the dextrose rate or insulin therapy if needed. Creatinine serves as a simple measure of kidney function; keeping an eye on it helps detect impaired renal clearance that could affect fluid and electrolyte management and overall PN tolerance. Phosphorus is closely watched because shifts in phosphorus can occur with PN and during refeeding, and hypophosphatemia can lead to muscle weakness, respiratory failure, and cardiac problems if not corrected. Taken together, these tests are commonly included in weekly monitoring to promptly identify and manage metabolic complications, making all of the above appropriate to include.
