answer
IV therapy
question
Large-volume IV infusions are administered on a ....?
answer
continuious basis
question
What type of IV infusions are administered on a continuous basis?
answer
Large volume IV infusions
question
-rapid absorption & onset of action -maintains constant therapeutic blood levels -less irritation to subcutaneous & muscle
answer
advantages of IV therapy
question
-circulatory fluid overload is possible if the volme of solution is large &/or if the infusion rate is rapid -immediate absorption leaves no time to correct errors -solution & IV catheter can cause irritation to the lining of the vein -failure to maintain surgical asepsis can lead to local infection & septicemia
answer
disadvantages of IV therapy
question
-prescribes the type of IV fluid, the volume to be infused, & either the rate at which the IV fluid should be infused or the total amount of time it should take for the fluid to be infused
answer
The provider
question
regulates the IV infusion to ensure the appropriate amount is administered -can be done w/ IV pump or manually
answer
The nurse
question
are administered on a continuous basis, such as 0.9% soldium chloride IV to infuse at 100mL/or or 0.9% sodium chloride 1,000mL to be given IV over 3 hr
answer
Large-volume IV infusions
question
is a large amount of IV fluid given in a short period of time, usually less than 1 hr. Given to rapidly replace fluid loss that could be caused by dehydration, shock, hemorrhage, burns, or trauma -a large gauge (18 or large) is needed to maintain the rapid rate necessary to give a fluid bolus to an adult
answer
Fluid bolus
question
-admin intermittenly in small amount of solution through continuous IV system, w/ saline or heparin lock systems -infuse for short periods on scheduled basis -can be admin by secondary ("piggy back") IV bag or bottl eor tandem set up, volume-controlled admin set, or by mini-infusion pump
answer
volume-controlled infusions
question
-typicall yin small amounts of solution, concentrated or diluted, that can be injected over short time (1-2 min) in emergent or nonemergent situations -admin directly into peripheral IV or access port to achieve an immediate med level in the blood stream, such as pain med -make sure med is prepared according to recommended concentration & admin according to safe recommended rate -use extreme caution & observe for complications such as redness, burning, or increasing pain
answer
IV bolus admin
question
-IV access can be via peripheral or central venous access device -central venous access devices can be peripherally inserted or directly inserted into jugular or subclavian vein
answer
Types of IV access
question
Never admin IV med through tubing that is infusing blood, blood products, or parenteral nutritional solutions
answer
*
question
-certain meds, such as potassium chloride, can cause serious adverse reactions. They should be infused on an IV pump for accurate dosage control, & never admin by IV bolus -never admin IV meds through tubing that is infusing blood, blood products, or parenteral nutritional solutions -verify the compatability of meds before infusing a med through tubing that is infusing another medication
answer
Guidelines for safe IV med admin
question
-be familiar w/ IV insertion equipment -avoid using needles when needless systems are available -use protective safety devices when available -dispose of needles immediately in designated puncture-resistance receptacles -do not break, bend, or recap needles
answer
Needlestick prevention
question
-avoid use of tourniquets (use a BP cuff instead) -do not slap the extremity to visualize veins -avoid rigorous friction while cleaning the site
answer
Special considerations for older adult clients, clients taking anticoagulants, or clients who have fragile veins
question
-apply digital pressure over the selected vein to displace edema -apply pressure w/ swab of cleaning solution -cannulation must be quick
answer
Special considerations for edema in extremities
question
may require the use of anatomical landmarks to find veins
answer
obese clients
question
-perform hand hygeine before & after handling the IV system -use standard precautions -change IV sites according to facility policy (usually 72 hr) -change continugious infusion tubing no more frequently than every 96 hr, & change intermittent infusion tubing every 24 hr according to facility policy -remove catheters as soon as no longer clinically indicated -change catheter if any break in surgical aseptic technique is suspected, such as emergency insertions -use a sterile needle/catheter for each insertion attempt -avoid writing on IV bags w/ pens or markers, b/c ink can contaminate the solution -change tubing immediately if contaminiation is known or suspected -fluids should not hang more than 24 hr unless its a closed system (pressure bags for hemodynamic monitoring) -wipe all ports w/ alochol or an antiseptic swab before connecting IV lines or inserting a syringe to prevent the introduction of micro-organisms into the system -never disconnect tubing for conveinence or to position the client
answer

question
6/1/2013, 1635, #22-guage IV catheter inserted into left wrist cephalic vein (1 attempt) with sterile occlusive dressing applied. IV 5% dextrose in lactated ringer's infusing at 100mL/hr per infusion pump without redness or edema at the site. Tolerated without complications. S. Velez, RN
answer
Sample documentation:
question
*Mainaining patency of IV access: -do not stop a continuous infusion or allow blood back into the catheter for any length of time. Clots can form at the tip of the needle or cathered & can be lodged against the vein wall, blocking the flow of fluid. -instruct the client not to manipulate the flow rate device, change the setting on IV pu,p, or lie on tubing -make sure IV insertion site dressing is not too tight -flush intermittent IV catheters w/ appropriate solution after every medication admin or every 8-12 hr when not in use -monitor the site & infusion rate at least every hr
answer
Postprocedure nursing actions
