Jugular veins, external and/or internal B. Subclavian veins C. Femoral veins (least preferred)
In patients at greater risk for catheter associated bloodstream infections (CABSI) what typed of PICC or non-tunneled catheters should be considered? - - - correct answer ✅Anti-microbial catheters What type of barrier precautions are required for non-tunneled catheter placement? - - - correct answer ✅Maximun sterile How should a patient be positioned for non-tunneled catheter placement? - - - correct answer ✅slight Trendelenburg position Why is a patient placed in slight Trendelenburg position for non- tunneled catheter placement? - - - correct answer ✅to avoid the possibility of air emboli during the placement procedure In non-tunneled catheter or PICC placement., what should always be avoided when accessing veins? - - - correct answer ✅Blind-stick attempts.
Why may the jugular vein be the preferred point of insertion in very young children for non-tunneled catheters? - - - correct answer ✅To avoid a pneumothorax What are the indications for placement of a PICC line? - - - correct answer ✅-Patients who require central venous access when the duration of the infusions are unknown -Infusion of irritating medications -Infusion of vesicant agents What are the contraindications of PICC line placement? - - - correct answer ✅-Placement into an arm with fracture, trauma, infection, amputations, or compromised circulation -Placement into an arm paralyzed as a result of a CVA may increase the risk of catheter-related thrombosis due to compromised circulation 4 -Chronic kidney disease patients
What vessels are selected for PICC line placement? - - - correct answer ✅Basilic, brachial or cephalic vein in the upper arm What barrier precautions are required for PICC placement? - - - correct answer ✅Maximum sterile What areas of tip location should be avoided in PICC line placement? - - - correct answer ✅Avoid catheter tip locations in the upper SVC or midclavicular areas What Alternative veins for PICC lines may be selected in pediatric pts.? - - - correct answer ✅Scalp veins, popliteal veins In pediatric patients, what, if added ,may decrease catheter occlusion? - - - correct answer ✅Heparin (confirm infusatn compatibility)
Where might tunneled catheter exits sites be located? - - - correct answer ✅The chest, upper back, top of thigh, or lower torso What attached to the catheter, will be positioned in the tissue track to secure the catheter? - - - correct answer ✅A stabilizing Dacron cuff After a tunneled catheter placement, how long until the exit site heals? - - - correct answer ✅Two to three weeks. When (upon physician approval) may a tunneled catheter be maintained without a dressing? - - - correct answer ✅Once the cuff has developed tissue attachment and the exit site is healed, In pediatric pts. with tunneled catheters, why do we assess/verify internal catheter tip location as the child grows? - - - correct answer ✅To maintain internal tip in the SVC
What are the indications for an implanted port? - - - correct answer ✅Infusions that are projected to continue for months to years What are the contraindications for an implanted port? - - - correct answer ✅-Severe coagulopathy -Severe, uncontrolled sepsis -Burns or cellulitis (affecting the intended insertion site) -Patient who is cachectic, below ideal body weight, or lacking subcutaneous tissue for port implantation What vessels are selected for a "peripheral" implanted port? - - - correct answer ✅Basilic or cephalic vein What vessels are selected for a "central" implanted port? - - - correct answer ✅Subclavian vein
