IV Therapy/ Medical Math Exam Review Flashcards
(47 cards)
What is the purpose of IV therapy?
to restore and replace intravascular volume
administer meds
maintain IV access in emergency situations
actual or POTENTIAL need
What are the INDICATIONS of the IV therapy ALS standard??
actual or potential need for IV meds OR fluid therapy!!
What are the CONDITIONS for IV CANNULATION as per the ALS IV and Fluid Therapy Medical Directive?
age over or equal to 2 years of age!!!!!!
What are the CONDITIONS for FLUID BOLUS as per the ALS IV and Fluid Therapy Medical Directive?
> = 2 years old
hypotensive!!! (<90mmHg SBP)
What are the CONTRAINDICATIONS for IV CANNULATION as per the ALS IV and Fluid Therapy Medical Directive?
suspected # proximal to the access site!!!
What are the CONTRAINDICATIONS for FLUID BOLUS as per the ALS IV and Fluid Therapy Medical Directive?
fluid overload of course
don’t give more fluid to overloaded fluid patients lol
What are the INFUSION RATES for maintenance infusion rate of someone aged >= 2 yrs old - <12 yrs old as per the ALS IV and Fluid Therapy Medical Directive?
15ml/hr
What are the INFUSION RATES for maintenance infusion rate of someone aged >=12 yrs old as per the ALS IV and Fluid Therapy Medical Directive?
30-60ml/hr
In what circumstance must we patch to BHP during the IV cannulation treatment of the ALS fluid and IV therapy medical directive?
for authorization to administer 0.9% saline fluid bolus to hypotensive pts 2-12 (paediatrics) with suspected DKA
What are the INFUSION RATES for a FLUID BOLUS rate of someone aged >= 2 yrs old - <12 yrs old as per the ALS IV and Fluid Therapy Medical Directive? (= the max volume and assess every ____mLs?)
20ml/KG
assess every 100ml
max volume of 2,000ml
What are the INFUSION RATES for a FLUID BOLUS rate of someone aged =>12 yrs old as per the ALS IV and Fluid Therapy Medical Directive? (= the max volume and assess every ____mLs?)
20ml/KG
assess every 250ml
max vol of 2,000ml
What are some clinical considerations in this directive??
micro drips should be considered for IV access in pts <12 y/o
PCP IV assist- an ACP can ask a PCP to cannulate an IV, but not administer any meds or fluid therapy
IV access should be considered for pt’s who do not meet the trauma TOR criteria
How do you calculate a child’s weight?
(age x2) +10= weight in kg
A PCP can monitor an intravenous IV line for a pt who…..
- an IV line TKVO
- an IV line for fluid replacement - with a max vol of 200ml/hr
- thiamine, multivitamin preparations
- drugs within his or her certification
- potassium chloride for pts >= 18 years old to a max pf 10mEq in a 250mL bag
What is extracellular fluid??
15% of total body weight
water found outside of the cell!!
What are the 2 diff types of extracellular fluid?
- intravascular- in the blood vessel
- intersistial - outside the vasculature but not in the tissue
What is intracellular fluid?
45% of total body weight
includes all fluids IN THE CELLS
How many body fluid compartments are there in the body?? And what percent of the body is water?
two areas!!!
70% of total body weight is water
Which part of the circulatory system has valves?
VEINS have valves to prevent backflow
What are the 3 layers of the veins and arteries?
tunica adventitia (outer)
tunica media (middle)
tunica initima (inner)
What are macro drip sets? What sizes are there?
bigger drop sets
10,15,20
commonly used for TKVO and large fluid admin (bolus)
What are micro drip sets? What are the purpose of it? What sizes is it??
60
to deliver meds over a long period of time
assist in the precise measurement of meds (dopamine)
control the amount of fluid for easily overloaded patients
(peds. and elderly/CHF)
margin of error is LESS with micro sets in vulnerable pts
What are the parts of the administration sets?
insertion spike
drip chamber
macrodrip stem
roller clamp
injection ports
needle adaptor
tubing
Why would we used micro drips?
to deliver meds over a long period of time
regulate the flow of meds precisely
to control the amount of fluid- such as in children and the elderly
for TKVO in pt’s when fluid overload is a concern (CHF)
