question

Advantages of IV therapy:

answer

-Rapid effects -Precise amounts -Less discomfort after initial insertion -Maintains control over therapeutic blood levels -Less irritation to subcutaneous and muscle tissue

question

Disadvantages of IV therapy:

answer

-Circulatory fluid overload is possible if the infusion is large and/or too rapid -Immediate absorption leave no time to correct errors -IV administration can cause irritation to the lining of the vein -Failure to maintain surgical asepsis can lead to local infection and septicemia

question

answer

Continuous basis

question

Fluid bolus

answer

Large amount of IV fluid given in a short period of time, usually less than 1 hour; given to rapidly replace fluid loss

answer

Large-gauge (18 gauge or larger)

question

Ways to give IV medications:

answer

-Mixed in a large volume of fluid (500 to 1000 mL) and given continuously -Premixed solution bags or added to the IV bag by a pharmacist -Volume controlled infusions -IV bolus dose administration

question

Volume-controlled infusion

answer

Given intermittently in a small amount of solution (25 to 250 mL) through a saline lock system; They infuse for short periods of time and are given on a scheduled basis; Can be administered by IV bag or bottle or tandem setup, volume-controlled administration set, or mini-infusion pump; Ex= antibiotics

question

IV bolus dose administration

answer

Usually small amounts of solution, concentrated or diluted, that can be injected over a short time (1-5 min) in emergent and non-emergent situations; Ex= Pain medications are given directly into a peripheral IV (central line) or access port; Make sure medications are prepared according to recommended concentration and at the recommended ratel Use extreme caution and observe for complications (redness, burning, swelling, or increasing pain) that may indicate phlebitis, infiltration, or extravasation

question

Central venous access devises can be inserted how?

answer

-Peripherally (PICC line) -Directly into the jugular or subclavian vein through venipuncture or surgical intervention with implantation of access ports for long-term use

question

Potassium chloride should only be given how?

answer

Electronic infusion pump; NEVER IV BOLUS; Always double-check the prescribed dose and correct dilution or amount of fluid

question

Medications should only be added to which container?

answer

A new container, not an IV container that is already hanging

question

Never administer medications through tubing that is infusing what?

answer

Never administer mediations through tubing that is infusing blood, blood products, or parenteral nutritional solutions

question

What should you verify before infusion medications through tubing that is infusing another medication?

answer

Verify compatibility

question

Special considerations for older adult clients, clients taking anticoagulants, or clients who have fragile veins:

answer

-Avoid tourniquets; use a BP cuff -Do not slap the extremity to visualize veins -Instruct the client to hold his hand below the level of his heart -Avoid using the back of the client's hand

question

Special considerations for edema in extremities:

answer

-Apply gentle pressure over the selected vein to displace edema -Apply pressure with an alcohol pad -Cannulation must be quick

question

Special considerations for obese clients:

answer

-Require the use of anatomical landmarks to find veins

question

Special considerations for preventing IV infections:

answer

-Use standard precautions -Change IV sites according to facility policy (usually 72 hrs) -Remove catheters as soon as they are no longer needed -Change catheter if any break in surgical aseptic technique is suspected, such as emergency insertions -Use sterile needle/catheter for each insertion attempt -Avoid writing on IV bags with tens or markers -Change tubing immediately if contamination is known or suspected -Fluids should not hang more than 24 hrs unless it is a closed system -Wipe all ports with alcohol or an antiseptic swab before connecting IV lines or inserting a syringe -Never disconnect tubing for convenience or to position the client -No not allow ports to remain exposed to air -Perform hand hygiene before and after handling the IV system

question

16 gauge used for who?

answer

Trauma clients, rapid fluid volume

question

18 gauge used for who?

answer

Surgical clients, rapid blood administration

question

22-24 gauge use for who?

answer

All other adult clients

question

Equipment for IV insertion:

answer

Correct size catheter, correct tubing, infusion pump, clean gloves, scissors or electric shaver for hair removal

question

Nursing actions for IV insertion:

answer

Check prescription; Assess for allergies; Rights of administration; Hand hygiene; Examine the solution for clarity, leaks, and expiration date; Prime the tubing; Don clean gloves before insertion; Assess extremities and veins

question

Select vein by choosing?

answer

-Distal veins first on the non dominant hand -Site that is not painful or bruised and will not interfere with activity -Vein that is resilient with a soft, bouncy feeling

question

What to document is the record:

answer

-Date and time of insertion -Insertion site and appearance -Catheter size -Type of dressing -IV fluid and rate -Number, locations and conditions of site-attempted cannulations -Client response

question

How to maintain potency of IV access:

answer

-Do not stop a continuous infusion or allow blood to back up into the catheter -Instruct the client not to manipulate flow rate device, change setting on IV pump, or lie on the tubing -Make sure IV site dressing is not too tight -Flush intermittent catheters after every medication administration or every 8 to 12 hours when not in use -Monitor site and infusion rate at least every hour

question

Infiltration Sx

answer

Pallor, local swelling at the site, decreased skin temp around the site, damp dressing, allowed infusion

question

Infiltration Tx

answer

-Stop the infusion and remove catheter -Elevate the extremity -Encourage active range of motion -Apply cold or warm compress based on the type of solution that infiltrated the tissue -Check with the provider to determine whether IV therapy is still needed

question

Infiltration prevention

answer

-Carefully select site and catheter -Secure the catheter

question

Extravasation Sx

answer

Pain, burning, redness, swelling

question

Extravasation Tx

answer

-Stop infusion and notify provider -Follow facility protocol which may include infusing an antidote before removal

question

Extravasation prevention

answer

-Closely monitor site and dressing -Always use infusion pump

question

question

Hematoma prevention

answer

-Minimize tourniquet time -Remove the tourniquet before starting the IV infusion -Maintain pressure after IV catheter removal

question

answer

-Promptly discontinue the infusion and remove the catheter -Elevate the extremity -Document the size of the infiltrated area, estimate the amount of fluid present and monitor the site -Apply cold compress to minimize the flow of blood, then apply a warm compress to increase circulation -Check with provider to determine whether IV therapy is still needed; if so, use different extremity -Culture the site and catheter is drainage is present

question
