Reaccess the port with a new needle, according to facility policy
When the nurse is drawing a blood sample from a client's central venous access device (CVAD), the blood stops flowing after the collection tube has been placed. The nurse removes the tube and flushes the lumen with 5 mL of saline solution. What is the next action by the nurse?
Redraw the waste sample.
The nurse is assessing the insertion site of a client's peripherally inserted central catheter (PICC). What is a normal finding?
a transparent dressing covering the site
Which is a normal finding upon assessment of a client's peripherally inserted central catheter (PICC)?
an insertion site free of blood and intravenous (IV) solution
The nurse is assessing a client's peripherally inserted central catheter (PICC) insertion site. The nurse measures the length of the catheter that extends out from the insertion site to:
assess if the catheter has migrated inward or moved outward
The nurse is flushing a client's peripherally inserted central catheter (PICC). What action should the nurse perform first?
cap the infusion line
The nurse is accessing the implanted port of a client's central venous access device (CVAD) to administer medications. After holding the port stable, the nurse should insert the needle into which location?
center of the port
The nurse is caring of a client who has a peripherally inserted center catheter (PICC) in place to receive antibiotics. As the nurse prepares to change the dressing of the PICC, how should the nurse position the client?
lying flat, with the arm extended from the body below heart level
The nurse is caring for a client receiving an antibiotic via a peripherally inserted central catheter (PICC). What two solutions should the nurse use to flush the line and keep it patent?
normal saline and heparin
The nurse is administering blood products to a client via an implanted port central venous access device (CVAD). What technique should the nurse use to locate the site of the port?
palpation
The nurse is inserting normal saline into the lumen of a central venous access device (CVAD) prior to obtaining a blood sample. What recommended amount of saline should the nurse use to flush the line?
5 to 10 mL
The nurse is removing the needle from the implanted port of a central venous access device (CVAD). At what angle would the nurse remove the needle?
90-degree
The nurse, drawing a blood sample from a client's central venous access device (CVAD), is unable to start the blood flow, despite trying a new specimen tube. What would the nurse do next to try to start blood flow?
Ask the client to raise the arm and cough
A nurse is caring for a client with a central venous access device (CVAD) whose implanted port will not be used for a long period of time. What action will the nurse take to maintain patency of the port?
Flush with heparin solution
Which action is important for the nurse to take prior to deaccessing the implanted port of a central venous access device (CVAD) to remove all substances from the port?
Flushing the port with normal saline
A nurse is preparing to access the implanted port of a client's central venous access device (CVAD). The nurse asks the client to turn the head away from the access site, but the client is unable to do so. What is the next action by the nurse?
Place a mask on the client
The nurse is observing an unlicensed assistive personal (UAP) drawing a blood sample from a client's central venous access device (CVAD). After the collection tube has been placed, the blood stops flowing. Which action by the UAP would require the nurse to intervene?

The nurse is collecting a blood sample from a central venous access device (CVAD). How much blood should the nurse collect in the discard tube?
4 mL
When completing a routine assessment of a client's peripherally inserted central catheter (PICC), the nurse finds no redness, swelling, or drainage at the insertion site. The transparent dressing is dry and intact and adheres to the skin around all edges. What is the most appropriate intervention at this time?
Ask the client about any pain or discomfort at the insertion site
The nurse is caring for a client who is receiving total parenteral nutrition. While changing the dressing of the client's central venous access device (CVAD), the nurse cleanses the site with chlorahexidine. Which action would the nurse perform next?

Flush the line with heparin
The nurse has collected a blood sample from a client's central venous access device (CVAD). After removing the vacutainer, what should the nurse do next?
Flush the line with normal saline.
When changing the dressing of a central venous access device (CVAD), how should the nurse remove the old dressing?
