  1. Which lipid emulsion is preferred in pediatric PN to reduce the risk of IFALD compared to soy-based emulsions?

    Answer: Fish oil-based lipid emulsion (Omegaven) or mixed emulsions (SMOF)

    Fish oil-based or mixed lipid emulsions (SMOF) contain omega-3 fatty acids and lower phytosterol content, reducing hepatic injury risk.

  2. What is the primary purpose of adding carnitine to parenteral nutrition in preterm neonates?

    Answer: To facilitate long-chain fatty acid transport into mitochondria for oxidation

    Carnitine is essential for transporting long-chain fatty acids across the mitochondrial membrane for beta-oxidation, and preterm infants have limited endogenous synthesis.

  3. Which clinical finding most strongly suggests catheter-related bloodstream infection (CRBSI) in a child receiving home PN?

    Answer: Fever coinciding with PN infusion that resolves when infusion stops

    Fever that begins during PN infusion and resolves after stopping is a hallmark presentation of CRBSI, indicating the central venous catheter as the infection source.

  4. For a pediatric patient requiring cyclic PN, what is the primary clinical benefit of cycling infusion over 12–16 hours nocturnally?

    Answer: Allows periods of fasting that reduce hepatic fat deposition and improve liver function

    Cyclic PN provides fasting periods that lower insulin levels, reduce hepatic lipogenesis, and allow for biliary flow, thereby protecting liver function.

  5. A preterm neonate on PN develops hypercalcemia. Which modification to the PN formulation is most appropriate?

    Answer: Reduce calcium and vitamin D content in the PN

    Hypercalcemia in PN-dependent neonates is managed by reducing calcium and vitamin D content to lower the calcium load being infused.

  6. Which formula characteristic is most important when selecting an enteral formula for a child with compromised GI absorption (e.g., Crohn's disease with stricture)?

    Answer: Hydrolyzed or elemental protein with reduced osmolality

    Hydrolyzed or elemental formulas reduce the digestive burden and improve absorption in children with impaired GI function.
