Lab 4: IV Bolus Flashcards
what is an IV bolus
- the intro of a concentrated dose of a med directly into the patient’s systemic circulation
what is the advantage of IV bolus
- requires only small amt of fluid to admin med = good if on restricted fluids
what is a con to IV bolus
- most dangerous method for med admin
- no time to correct an error
- may cause direct irritation to lining of blood vessels
what should you do before administering a bolus
- confirm placement of IV line by obtaining blood return
what does the inability to obtain a blood return indicate
- needle or catheter is in patients tissues or resting against vein wall
when should you never give an IV bolus
- if insertion site is puffy edematous, if IV fluid cannot flow at proper rate
what can accidental injection of IV bolus into tissue around a vein cause (3)
- pain
- sloughing of tissues
- abscesses
how do you determine the rate of admin of an IV bolus
- amt of med/min
if you make an error during IV admin, what should you do and why?
- report immediately to minimize harm
what should you do before and after admin of IV med? why?
- flush
- before = verify IV placement
- after = ensures right dose & time
what are indications for IV push (4)
- emergencies –> fast acting
- if limited IV access
- if multiple meds to infuse
- for meds for pt comfort (nausea, pain)
what makes giving a med IV push more critical than other secondary infusion methods (3)
- med acts quickly = adverse effects
- no time to correct errors
- irritating to veins
what is order range
- the range indicated on the PDM
ex. morphine dose 2.5-5 mg
describe the difference between diluted and nondiluted
- if PDM says undiluted you can still dilute (if dose is v small) –> best practice if to avoid diluting if PDM says not to
- if PDM says diluted, you must dilute it
why is it best practice to not dilute a drug that says undiluted in PDM (3)
- potential for errors
- risk for contamination
- drug stability when diluted
