How should PN ingredients be ordered for adults?

• A. PN ingredients shall be ordered in amounts per day for adults
• B. PN ingredients shall be ordered by weekly totals
• C. PN ingredients shall be ordered by hourly rate
• D. PN ingredients shall be ordered as total daily dose

Answer: (A)

This question tests how parenteral nutrition ingredients are ordered for adults: you specify daily amounts to match the patient’s ongoing, day-to-day needs. In adults, caloric and protein requirements, fluid balance, electrolytes, and micronutrient needs can change with weight, illness, labs, and metabolic state, so the PN plan is reassessed each day and the pharmacy prepares a fresh order reflecting that day’s requirements. Ordering by weekly totals would not keep up with daily fluctuations, and hourly rates aren’t how PN orders are structured in standard practice. The idea of a total daily dose essentially mirrors daily amounts, but the routine approach is to order in daily amounts to allow precise daily adjustments.
