CH 4 Intravenous Therapy Flashcards
Advantages of IV therapy
- Rapid effects
- Precise amounts
- Less discomfort after initial insertion
- Constant therapeutic blood levels
- Permits the use of large volumes of fluid for medications that are poorly soluble and need larger amounts of fluid to dissolve
- Permits the use of medications that contain irritant properties, such as chemotherapy
Disadvantages of IV therapy
- Circulatory fluid overload is possible if the infusion is large or too rapid
- Immediate absorption leaves little time to correct errors.
- IV fluid administration can irritate the lining of the vein
- Failure to maintain surgical asepsis can lead to local and systemic infection
Ways to administer IV medications
- Give the medication to the pharmacist mixed in a large volume of fluid (500 to 1,000 mL) as a continuous IV infusion, such as potassium chloride and vitamins
- Deliver the medication in premixed solution bags from the medication’s manufacturer
- Administer volume-controlled infusions.
- Give an IV bolus dose
Guidelines for Safe IV Medication Administration
- Use an infusion pump to administer meds that can cause serious adverse reactions. Never administer them by IV bolus. Double-check the dose prescribed. the dilution or amount of fluid, and the rate at which to give the med
- Add meds to a new IV fluid container, not to an IV container that is already hanging
- Never administer IV meds through tubing that is infusing blood, blood products, or parenteral nutrition solutions
- Verify the compatibility of medications with IV solutions before infusing meds through tubing that infusing an IV solution
- Perform any assessments required prior to administration, based on the medication, and determine if continuous monitoring is required during administration (ECG).
- Use the IV port closest to the client to administer the medication
- Ensure the IV is patent prior to administration. If the client does not have IV fluids infusing or has fluids that are not compatible with the medication, flush the IV access before and following administration.
Specific Considerations for Older adult clients, clients who are taking anticoagulants, and clients who have fragile veins
- Avoid tourniquets. Use a blood pressure cuff to help visualize, but not over-distend, the veins to help prevent hematoma formation.
- Do not slap the extremity to visualize veins
- Instruct the client to hold their hand below the level of the heart to help distend and thus visualize the veins
- Avoid using the back of the client’s hand
- Avoid rigorous friction while cleaning the site
Specific Considerations for clients who have edema in extremities
- Apply digital pressure over the selected vein to displace edema
- Apply pressure with an alcohol pad
- Cannulate the vein quickly
Specific Considerations for clients who are obese
Use anatomical landmarks to find veins
What should you do if there is a complication with the IV?
Notify provider, complete documentation, use new tubing and catheters for restarting IV infusions after detecting complications
IV Complications include
Infiltration, Extravasation, Catheter embolus, phlebitis/thrombophlebitis, cellulitis, fluid overload
What is infiltration?
infiltration of a non-vesicant solution
Infiltration: Expected Findings
Pallor, Local swelling at site, Decreased skin temp around site, Damp dressing, Slowed infusion
Infiltration: Treatment
- Stop the infusion and remove the catheter
- Elevate the extremity
- Encourage active range of motion
- Apply a cold or warm compress depending on the type of solution that infiltrated the tissue
- Check w/ the provider to determine whether the client still needs IV therapy. If so, restart the infusion proximal to the site or in another extremity.
Infiltration: Prevention
- Carefully select the site and catheter
- Secure the catheter.
- Inspect IV infusion site frequently for any findings of infiltration
What is extravasation?
infiltration of a vesicant or tissue-damaging medication
Extravasation: Expected Findings
Pain, Burning, Redness, Swelling
