Ch 16: Parenteral Access Devices Flashcards
The leading complication with peripheral intravenous infusion is
thrombophlebitis
(an inflammation at the cannulation vein)
What are the signs/symptoms of phlebitis?
ASPEN self assessment - PN
pain, erythema, tenderness or a palpable cord
The risk of thrombophlebitis increases by
ASPEN self assessment - PN
day 4
Infusion rates of phosphate should not exceed 7 mmol/hr because faster rates can cause:
ASPEN self assessment - PN
thrombophlebitis and soft tissue calcium-phosphate deposition
True or Fale: Catheter replacement at scheduled time intervals has not shown a decrease in CRBSI.
True
Current CDC recommendations regarding CVADs and infection:
ASPEN self assessment - PN
- Do not remove CVCs or PICCs based on fever alone
- Clinical judgment should be used to determine appropriateness of catheter removal if infection is evidenced from another site or a noninfectious cause is suspected
- Catheter insertion over a guidewire is associated with less discomfort and a lower rate of mechanical complication when compared to percutaneous insertion at a new site
A peripherally inserted central catheter (PICC) is defined as a catheter inserted via the _ _ _ vein whose distal tip lies in the _ _ _

peripheral vein
superior vena cava
Which veins are often used as the insertion site for PICCs?
ASPEN self assessment - PN
The cephalic or basilic veins
Central or peripheral access is not defined by the initial point of entry into the vascular system but rather by the position of the distal catheter tip.
ASPEN self assessment - PN
Central lines are defined as catheters with the distal tip in either
ASPEN self assessment - PN
Superior or inferior vena cava
Therefore, by definition, a PICC is used as central venous access.
