What is the vein of choice for peripherally inserted central catheter (PICC) insertion?
basilic
median
external jugular
cephalic
Confirmation of PICC tip placement and adequacy in insertion is achieved by:
successful infusion of 0.9% saline
visual blood return
Chest X-ray
measurement of catheter length from point of insertion
When irrigating a central line, the barrel capacity of the syringe used to flush the line must be no smaller than
3 ml
10 ml
1 ml
5 ml
When a central line is flushed, at least 10 ml of 0.9 % NS should be instlled with
a slow , smooth push of irrigant
a rapid forceful and continual push of irrgant
a rapid succession of push-pause movemnts
when drawing blood samples from a central line, which of the following is true? SATA
blood should not be left in the cap following phlebotomy
the procedure should be done by the laboratory phlebotomist only
only the proximal port should be used for blood draws
any infusates should be turned off at least 1 minute prior to blood draw
The catheter tip position desired for picc line is
SVC
Axillary of the subclavian vein
IVC
the axillary vein
which of the following is an indication for use of central venous catheter? select all that apply.
routine isotonic maintenance fluid infusions in the stable patient in an acute care setting
for infusion of medications that are damaging to the veins
for administration of infusions in the critical care setting
for long term outpatient infusion therapy
when venous access device is suitable for long term use and involves the insertion of a device placed entirely subcutaneously in the patient
centrally implanted port
peripheral IV line
centrally inserted venous catheter
peripherally inserted venous catheter
what is the purpose of using heparin to flush and lock a central or peripheral central catheter
it prevents infection
it prevents phlebitis
it prevents an embolism
it prevents thrombus formation
the nurse would expect a central line to be placed in a vessel in the right neck of a patient or on the right side of the upper body for what reasons. select all that apply.
less equipment needed
less risks of pneumothorax
reduced risk for infection at insertion
less tortous vssels, straighter
why would the tip of the central cathetr need to remain outside the RA. select all that apply
traversing the SA node could cause dysrhthmias
migration into the tricuspid valve could cause valvular damage
termination in the RV could cause the tricuspid valve to remain open and cause for fluid retention
termination of the line in the RA could cause pericarditis
which complication of central line placement is due to break in aseptic technique. select all that apply
hemothorax
and
catheter Embolus
pulmonary edema
and
air embolism
sepsis
local infection
how does the nurse attempt to prevent an air embolism from occuring when maipulating or providing maintenance care on a central line
have the patient perform the valsava maneuver during tubing, cap changes
heparanize the line after each use
follow strict aseptic technique during dressing changes
avoid using the central line for blood draws
Should an air embolism be suspected in the patient. how should the nurse respond?
apply o2 to the patient and monitor VS for 1 hour, watch for improvement
place the patient in high fowlers position, apply oxygen and monitor V/S
place the patient in left trendelenburg position, apply o2 and notify the physician immediately
Lay the patient supine and clamp the central line catheter and notify the doctor
If TPN were in use, which port would be used exclusively for TPN administration and nothing else
the fourth lumen
the distal port
the proximal port
the medial port
the lumen designation tells what about the central line catheter? select all that apply
the uses of the lumen
the infusates allowed ti be infused into the lumen
the size of each lumen
the location in the catheter stem where each lumen terminates, or opens into the bloodstream
when should the dressing covering a central or peripheral central catheter be changed? select all that apply.
when it is loose and not adhering
when it is wet
when it is visibly soiled
every 14 days
which of the statements is true in the care of a central or peripheral central catheter? select all that apply
the lpn is to have knowledge of the device and potential complications to observe for
the lpn is to obseve and report changes, problems or concerns with these devices to the RN
LPNs are not allowed by law to manipulate central lines
the lpn may administer and perform maintenance on the devices, acccording to facility polcy...
if a central venous catheter is used and access is obtained in the femoral vein, where would the tip of the central catheter lie
in the IVC
in the subclavian vein
in the RA of the heart
In the SVC
what is the name for the needle specifically used to access a central infusion port
a hickman catheter
a huber needle
a groshong device
a leonard catheter
