Mr. Ford has an intravenous antibiotic prescribed. How should the practical nurse administer this medication?

• A. Add the antibiotic to the protein and electrolyte solution.
• B. Administer it in the fat emulsion solution.
• C. Administer it via Y-tubing to the PICC line.
• D. Commence an additional peripheral intravenous line in a separate vein.

Answer: (D)

When IV medications are given to a patient receiving total parenteral nutrition, they must not be mixed with or infused through the PN line. PN solutions contain amino acids, electrolytes, and often lipid emulsions, and many antibiotics are chemically incompatible with these components. Infusing a drug through the same line or bag can cause precipitation, line occlusion, altered drug activity, or safety risks for the patient. The best approach is to establish a separate IV access—an additional peripheral IV line in a different vein—to administer the antibiotic. This keeps the antibiotic separate from the PN, avoids compatibility problems, and ensures the medication is delivered safely and effectively.
