IV Therapy
How do we keep our inner fire alive? Two things, at minimum, are needed: an ability to appreciate the positives in our life - and a commitment to action. Every day, it's important to ask and answer these questions: 'What's good in my life?' and 'What needs to be done?‘
Nathaniel Branden

A client is to receive 2000 ml of IV fluid in 12 hours. The drop factor is 10 gtt/ml. As the nurse you need to regulate the flow so the number of drops per minute is approximately?

IV therapy
Goals of IV therapy
-maintenance therapy for daily body fluids
-replacement therapy
-provide fluids and electrolytes (homeostasis)

Saline Lock Device
Nursing Responsibilities
calculations, monitor cannula patency, site, surrounding area, flow rate(micro vs macro drip), patient response

q1H IV site
q4H checks as well
IV tubing changed every 72 hours
IV site changed every 7 days as with dressing
Fluid Volume Excess
-occlusion or blood clotting
-speed shock
-port of infection
-skin integrity
Risks, Complications and Safety Issues
Nerve Injury
Venous Spasm
Air embolism
Fluid overload
Speed shock
Basic Principles of Electrolytic Balance
Roles of electrolytes
-maintaining electro-neutrality in fluid compartments
-mediating enzyme reactions
-altering cell membrane permeability
-regulate nerve impulse transmission
-influence blood clotting time

Body Fluid Composition
Body fluid composition
Water; males 60% females 50-55% infants 70-80 %

ICF: intracellular fluid 40% of water
ECF: extracellular fluid 20% Interstitial 15%
Intervascular 5%
Normal Fluid losses
-lungs 300 to 500 ml / 24 hours
-skin 500 ml per day
-GI 100 to 200 per day
ICF Plasma ECF
HPO4- Cl- Cl-
K Na Na
Fluid volume Deficit
-shift of fluid into a third space (interstitial or intervascular)
-loss of blood volume
-dehydration, fever, GI loses, burns, hemorrhage
-loss of electrolytes
S& S
-increase in HR, weak rapid pulse, decrease in BP and tenting, postural hypotension, dry membranes, oliguria < 30 ml/hr
-excess secretions of ADH due to pain, fever, infection, post-operative reaction
-excessive IV fluids
-excessive irrigation of body cavities
-cardiovascular dysfunction
-bounding pulse, increase in tenting and BP, crackles heard over lungs, SOB, cough, edema, weight gain, polyuria
-more flexibility while maintaining vascular access for emergency meds
-reduced volume of fluid administration
-reduced risk of electrolytic imbalance
-maintenance therapy for NPO patients
-quickly provide fluids, electrolytes and medications
-decrease pain/discomfort from frequent injections
-control over fluid input and easy monitoring
-better for patients who cannot tolerate PO meds (impaired GI tract)
-some drugs cannot be absorbed by other routes

-port of infection
-fluid overload
-drug incompatibilities
-risk of electrolyte imbalances
-once every 12 hours and before and after medications
-pulsing pressure
-3 mls for peripheral lines
-checked off on MAR
-stop if pain, inflammation and leaking at site.
-when discontinuing (hold pressure for 3 minutes, if patient is on anticoagulants hold for 5 min, then monitor as per unit policy.
Types of Commonly Used Fluids
0.45% sodium chloride

in body
3.3 % dextrose in 0.3% sodium chloride (2/3 - 1/3)
0.9% sodium chloride
Ringers Lactate
5% dextrose
in body
