iv maintainance 3

What is the purpose of a peripheral IV catheter?

To maintain short-term Venous access

What gauge IV catheter is commonly used for blood administration?

Larger gauge such as 18 or 20 gauge

Which IV catheter group is smaller 18 or 24

24 gauge. The bigger, the gauge the smaller than the needle.

Why are smaller gauge catheter used?

For fragile veins or slower infusions

What should the nurse verify before administrating IV therapy?

Provider order, patient identity, solution rate and site condition

What are the key steps in maintaining an IV system?

Assess site monitor flow rate, maintain sterility and check tubing/solution

What are the key steps when discontinuing a peripheral IV?

Infusion remove catheter supply pressure inspect catheter and document

What should be documented during IV maintenance?

Site condition fluid type/rate dressing changing and patient response

Why is monitoring IV therapy important?

To prevent complications and ensure safe fluid administration

Isotonic

Stays in the bloodstream example : normal saline , lactate ringers

Hypertonic

Fluid that moves out of the cells example D5NS and 3% saline

Hypotonic

Fluid moves into cells example 0.45% normal saline

Which fluid caused the cells to shrink ?

Hypertonic

Which fluid causes cells to swell?

Hypotonic

Infiltration

Fluid leak sensor tissue and the IV site is cool, swollen pill painful, and you should stop infusion immediately. Think fluid in tissue equals cold/puffy.

Phlebitis

Vein inflammation Iv site is warm, Red, tender, streaking stop Iv - think phlebitis equals heat/redness

Circulatory overload

Too much fluid symptoms include crackles , Dyspnea , edema, distended neck ranges, increased blood pressure. Nurse actions - slow/stop Iv , raise the head of the bed, notify provider

Air embolism

Air enters bloodstream and it’s very serious. Symptoms include chest, pain, dyspnea, and hypotension. Nurse action include clamp tubing, left

Side trendelenburg and notified provider.

What should the nurse always assess?

Iv site ,flow rate, solution ,tubing ,patient response

Before hanging a new IV bag check

Correct patient, correct solution ,expiration date, clarity of fluid

Why remove air from tubing?

To prevent air embolism

Why use aseptic technique?

To prevent infection

Gauge sizes

Smaller number equals bigger catheter

18 gauge

Blood/rapid fluids

22-24 gauge

Elderly / fragile veins

Discontinue IV

Stop infusion, remove tape/dressing, remove catheter, apply pressure, inspect catheter tip, dress site, document

Baxter pump/infusion pump

Used to regulate IV flow accurately, alarms, if occlusion, air in line, bag empty, low battery. Nurse should assess patient/1st when alarm sounds.

First action stop the infusion

If patient complains of burning, swelling, pain, coolness

Infiltration

Call and swollen

Phlebitis

Hot and red

Hypertonic

Pulls fluid out

Hypotonic

Pushes fluid in

Smaller gauge number

Bigger catheter
