Mod 9 W&H chap 7 Flashcards
sometimes called a saline lock; small volumes of fluid or medication administered over 15 mins - 2 hours by IV push or infusion through the resealable diaphragm
intermittent device
large volume infusion of solution typically 250 -1,000mL, administered over 2-24hours; delivered in mL; this infusion is kept running constantly until order is discontinued
Continuous infusion
infused over a short period of time; may be done as an intermittent infusion; antibiotics (secondary) infusion is to be hung higher than primary solution
piggyback/secondary infusion
what solution is used for maintaining peripheral intermittent devices?
sodium chloride
what solution is recommended for flushing central venous access devices?
Heparin, an anticoagulant (remember—heparin is a medication and may be incompatible with other medications. check institutions policy for guidelines)
? ? must be maintained in the lumen of the cannula during the administration of the flush solution to prevent a back flow of blood into the cannula lumen.
Positive pressure
medication is injected slowly via a syringe into an IVsite or tubing port. provides a rapid effect. Sometimes referred to as a “bolus”
IV push (IVP)
solution is positioned about 3 feet above infusion site; flow is controlled with a roller, screw, or slide clamp
Gravity drip
what are the typical drip rates used
10, 15, 20, or 60 drops per milliliter of fluid
sets delivering 10, 15, or 20 drops per milliliter are called? Used for fluids that need to be infused more quickly.
macrodrop sets
used for solutions that need to be infused more slowly. 60gtts/mL
Microdrop or minidrop sets
To determine drops per min of an iv solution, the nurse needs to know ?
the amount of fluid to be given in a specified time interval and the drop factor of the administration set to be used.
the flow rate increases as..
the distance between the solution and the pt increases.
what is the ideal height for a solution?
3 feet about the level of the pts heart
clot formation can result from…
irritation, increased venous pressure, or backup of blood into the line.
