Which site is generally preferred for peripheral IV insertion in an infant under 6 months of age when upper extremity veins are inaccessible?
Answer: Scalp vein
Scalp veins are commonly used in infants under 6 months because they are superficial, accessible, and allow the infant's hands to remain free.
A 10-year-old receiving total parenteral nutrition (TPN) via a central line develops sudden onset of chest pain and dyspnea. The nurse should first suspect which complication?
Answer: Air embolism
Sudden chest pain and dyspnea during central line infusion are classic signs of air embolism, a life-threatening complication requiring immediate intervention.
When using a needleless connector on a pediatric central venous catheter, which technique best reduces the risk of intraluminal contamination?
Answer: Scrubbing the hub with 70% alcohol for at least 15 seconds before each access
Scrubbing the needleless connector hub with 70% alcohol for a minimum of 15 seconds ("scrub the hub") is the evidence-based practice to reduce intraluminal contamination.
A 3-year-old with sickle cell disease is receiving a simple red blood cell transfusion. After 50 mL, the child develops fever, chills, and back pain. Which transfusion reaction is most likely?
Answer: Acute hemolytic transfusion reaction
Fever, chills, and back pain occurring shortly after transfusion onset in sickle cell disease are classic signs of acute hemolytic transfusion reaction due to ABO incompatibility.
Which method is recommended to confirm correct nasogastric tube placement before administering medications or feedings in a pediatric patient?
Answer: pH testing of aspirate (pH ≤ 5.5) confirmed by X-ray on initial placement
pH testing of gastric aspirate combined with radiographic confirmation on initial placement is the most reliable method; auscultation alone is not considered reliable.
A pediatric patient on long-term home IV vancomycin therapy develops tinnitus and decreased hearing. Which action should the infusion nurse take first?
Answer: Hold the dose and notify the prescriber immediately
Tinnitus and hearing loss are signs of vancomycin ototoxicity; the dose should be withheld and the prescriber notified immediately to reassess the regimen.
When calculating osmolarity of a peripheral parenteral nutrition solution for a neonate, what is the maximum recommended osmolarity to minimize risk of phlebitis?
Answer: 900 mOsm/L
Solutions with osmolarity up to 900 mOsm/L are generally considered acceptable for short-term peripheral administration in neonates to reduce the risk of thrombophlebitis.
