Which factor has been associated with an increase in PN prescribing errors?

• A. Calculation of PN dosages
• B. Standardized PN order form
• C. PN components listed in same sequence on order form as PN label
• D. PN components ordered as amount per day

Answer: (A)

Calculating PN dosages is a high-risk step because parenteral nutrition involves precise amounts of calories, amino acids, lipids, electrolytes, and trace elements tailored to each patient. Small arithmetic mistakes, unit conversion errors, or misapplying weight-based or daily requirements can lead to over- or underfeeding and electrolyte disturbances. These calculation steps are common points where errors occur, especially when orders change or multiple clinicians contribute to the prescription. By contrast, using a standardized PN order form or listing components in the same sequence as the PN label helps reduce variability and confusion, and arranging components as daily amounts can clarify targets. So the act of calculating PN dosages is the factor most strongly associated with increased prescribing errors.
