  1. What is the primary reason chlorhexidine gluconate (CHG) skin antisepsis is used with caution in neonates under 2 months of age?

    Answer: Immature neonatal skin allows significant percutaneous absorption causing systemic toxicity

    The thin, permeable skin of neonates, especially preterm infants, allows CHG to be absorbed systemically, potentially causing chemical burns and systemic toxicity.

  2. Which veins should be avoided for PICC insertion in a pediatric patient with chronic kidney disease who may require future hemodialysis?

    Answer: Basilic and cephalic veins of the non-dominant arm

    Preserving the basilic and cephalic veins of the non-dominant arm is essential for potential future AV fistula creation in patients with chronic kidney disease.

  3. A 5-year-old child has a midline catheter placed in the right basilic vein with the tip confirmed at the mid-upper arm. Which infusate is appropriate for this device?

    Answer: Vancomycin at standard concentration

    Midline catheters are appropriate for isotonic or near-isotonic infusates such as standard-concentration antibiotics, but are not indicated for vesicants, hyperosmolar solutions, or vasopressors.

  4. When performing ultrasound-guided peripheral IV placement in a child, the short-axis (transverse) view is used to:

    Answer: Identify vessel location, depth, and surrounding structures during needle approach

    The short-axis view provides a cross-sectional image that allows the clinician to identify vessel location, assess surrounding structures, and guide needle placement.

  5. A neonate requires umbilical venous catheter (UVC) placement. The correct tip position is:

    Answer: At the junction of the inferior vena cava and right atrium

    The UVC tip should be positioned at the IVC–right atrial junction to avoid hepatic complications such as portal hypertension or hepatic necrosis.

  6. Which factor MOST increases the risk of catheter-associated bloodstream infection (CLABSI) in pediatric patients with central venous catheters?

    Answer: Presence of femoral venous access site

    The femoral site carries a significantly higher CLABSI risk compared to subclavian or internal jugular sites due to proximity to the perineum and higher bacterial colonization.

  7. A pediatric patient's implanted port requires access. Which needle type must be used to access the port septum?

    Answer: Non-coring (Huber) needle

    A non-coring Huber needle must be used to access implanted ports; standard needles core the silicone septum and damage the port, leading to leakage.
