30
Q

how long can a continuous infusion be hung for?

A

72-96hrs

31
Q

What are the 4 steps to administer a heparin bolus IVP and start heparin infusion through a PVAD?

A
  1. administer herapin IV bolus
  2. hang heparin infusion OR if bolus not required
  3. start infusion
  4. document
32
Q

in reagards to the 4 steps to administer a heparin bolus IVP and start heparin infusion through a PVAD describe administering a heparin IV bolus

A
  • SL lock as an IV push per policy (over 1min)
  • patency check
  • pre-med flush (3-5ml)
  • post med flush (10mL)
33
Q

in reagards to the 4 steps to administer a heparin bolus IVP and start heparin infusion through a PVAD describe hanging heparin infusion

A

place tubing in pump

- program pump to appropriate medication name/ rate

34
Q

in reagards to the 4 steps to administer a heparin bolus IVP and start heparin infusion through a PVAD describe if bolus not required

A
  • perform patency check
  • flush SL with NS
  • attach heparin drip tubing to run as primary infusion
  • if another IV running attach heparin to lowest port of running IV as a tandem if compatible
  • press run
35
Q

in reagards to the 4 steps to administer a heparin bolus IVP and start heparin infusion through a PVAD describe documenting

A
  • on MAR
  • VAD record
  • intake/output record
36
Q

after heparin drip has been initiated infusion rates are adjusted based on what?

A

37
Q

What supplied do you need when reconstituting a powder medication?

A
  • medication
  • compatible solution
  • blunt non filter needle
  • syringe

What can lead to under-dosing of medication and non-therapeutic drug levels?

A

when discarding medication infusion set where there is still a residual amount of IV drug left in tubing

49
Q

How do you avoid underusing of IV infusion medication?

flush fluid to administer remaining med by either doing this manually or hang a 50mL bag of compatible fluid and run at same rate

50
Q

nurse’s decision-making about IV administration set replacement is based on what?

A
  • infection prevention
  • physical safety
  • patient preference
  • clinical knowledge and beliefs
  • workload
51
Q

excluding lipid, blood and blood products most hospitals routinely change IV tubing every 96 hours or up to 96 hours. Why?

A

prevent catheter-related bloodstream infection

52
Q

What is a tandem infusion?

A

second IV line connected to the primary line at the lower port below pump

53
Q

when can medication be given in regards to tandem infusions?

A

intermittently or at the same time as primary infusion

54
Q

What is the difference between a tandem and a piggyback infusion?

A

tandem
- connected below the pump

piggyback
- connected above the pump

55
Q

Where do you document an IV med infusion?

A
  • MAR
  • VAD record
  • in/out record
  • narrative notes if needed
