Fluids and electrolytes Flashcards
IVs are for people who
are unable to eat or drink properly
Are NPO prior to surgery
have pre-existing electrolyte or fluid imbalances
require IV medications
require blood
require TPN (total parenteral nutrition)
What is the purpose of an IV
supply fluid, salts and electrolytes, provide glucose, restore volume of blood by administerstration of components such as plasma or albumin, administer meds or vitamins.
common places for IV
vein, hand, elbow, foot, head
The smaller the number go cathlon the
bigger the diameter of gauge
What might make you want to choose a larger gauge cathlon over a smaller gauge?
Age/size of vein. What you are infusing.
Larger gauge is better for rapid infusion. 14-24 gauge
when do you replace a IV dressing
damp, loose, soiled or when IV site changed
what is a saline lock
Occasionally an IV infusion is initiated and maintained with a saline lock:
to provide access to the circulatory system in an emergency
to administer medications at intervals
how much do you flush an adults saline lock with
3 mL of Sodium Chloride
When do we flush a saline lock
prior to use (assesses catheter function)
following use
every 24 hours and prn
Flush teqhnique
stop, start
Prior to flush what is important to do
swab with alcohol wipe
how high should the patients bag be
76.2 cm
formula for drip rate
Volume in mL x drop factor divided by time in minutes
Complications
Infiltration
Phlebitis
Infection
Fluid overload
Electrolyte imbalance
Air Embolus
Infection can by caused by
improper insertion technique
Hematoma can be caused by
inserting IC catheter through the vein or by not applying enough pressure at removal
Infilteration
Catheter slips out of the vein and fluid escapes into the subcutaneous tissue causing swelling, pallor, coldness (↓ flow rate)
Infiltration interventions
discontinue IV and restart in different site
elevate – promotes venous drainage and apply warm compresses to ↑ circulation to area and carry away extra fluid
Do not rub or massage area
How to prevent infiltration
Check infusion site several times per shift. Get patients to report discomfort to you. Limit movement of extremity with patients who have an IV.
