  1. Which complication is associated with too-rapid infusion of hypertonic dextrose in a TPN solution without adequate insulin?

    Answer: Hyperglycemia

    Rapid infusion of concentrated dextrose in TPN can cause hyperglycemia if insulin coverage is insufficient.

  2. What is the maximum recommended final concentration of dextrose in a peripherally administered IV admixture?

    Answer: 12.5%

    Peripheral parenteral nutrition should not exceed 12.5% dextrose to avoid phlebitis and vein damage.

  3. Which amino acid solution component is responsible for providing nitrogen in TPN formulations?

    Answer: Crystalline amino acids

    Crystalline amino acid solutions provide the nitrogen needed for protein synthesis and tissue maintenance in TPN.

  4. A compounding technician notices that a TPN admixture has a yellowish oily layer floating on top. This most likely indicates:

    Answer: Lipid emulsion cracking or breaking

    A floating oily layer in a 3-in-1 TPN indicates that the lipid emulsion has cracked (phase-separated), making it unsafe for use.

  5. Which vitamin is typically added to TPN separately and protected from light due to its photosensitivity?

    Answer: Vitamin A

    Vitamin A is highly photosensitive and degrades rapidly when exposed to light, requiring light-protected IV tubing or bags.

  6. What USP chapter applies to endotoxin (pyrogen) testing of large-volume parenteral preparations like TPN?

    Answer:

    USP Bacterial Endotoxins Test is used to detect pyrogens in large-volume parenterals including TPN formulations.
