What is the recommended method for securing a peripheral IV catheter to prevent dislodgement?
Answer: Manufactured catheter stabilization device (engineered stabilization device)
INS standards recommend manufactured engineered stabilization devices (ESDs) over tape to reduce catheter movement, decrease phlebitis, and prevent unplanned dislodgement.
When performing PICC tip confirmation, what landmark indicates proper placement on a chest X-ray?
Answer: Lower third of the SVC at or near the caval-atrial junction
The ideal PICC tip position is in the lower third of the SVC at or near the caval-atrial junction, confirmed by chest X-ray before initiating infusion therapy.
What is the correct procedure for accessing an implanted port?
Answer: Palpate the port, cleanse with CHG, access with a non-coring (Huber) needle using sterile technique
Port access requires aseptic technique, CHG skin antisepsis, and a non-coring Huber needle to prevent damage to the port septum.
How should the CRNI manage a central venous catheter with a suspected partial occlusion?
Answer: Use a gentle push-pull technique with a 10 mL syringe; if unsuccessful, instill alteplase per protocol
Partial CVC occlusion should be managed with gentle flushing technique using an appropriate syringe size, followed by thrombolytic instillation if mechanical methods fail.
What is the rationale for using ultrasound guidance during PICC insertion?
Answer: It improves vein visualization, increases first-attempt success, reduces complications, and aids in vein-to-catheter ratio assessment
Ultrasound guidance provides real-time vein visualization, enabling optimal vein selection, improved first-attempt success, and reduced mechanical complications during PICC insertion.
What is the CRNI's responsibility regarding midline catheter tip position?
Answer: Midline catheter tips must remain in the peripheral vasculature, with the tip at or below the axillary vein level
Midline catheters are peripheral devices with tips that must remain in the upper arm vasculature at or below the axillary vein level - they are NOT central venous access devices.
