test 5 Flashcards
Medications ordered in units/hour or mg/hour formula
(desired)(mL)/
(have). =ml/hr
e.g.
(units or mg/hr)(mL)/
(have in units or mg). =mL/hr
concentration formula
amount of drug/
amount of fluid in mL =concentration
advanced IV medications are
very potent medication
small changes to the infusion rate can greatly affect
the body’s physiologic response
who prepares advanced IV medications
pharmacy
how are advanced IV medications administered
pump
pump aka
smart pump
many pumps can deliver
rates less than 1 (e.g. 0.5)
what does the pump calculate
how much medication the patient recieves
what does the nurse have to program into the pump
drug amount, patient weight, & time
advanced IV medications used in critical care
HIGH ALERT MEDS e.g.
heparin and insulin drip
IV anticoagulant
heparin
why is insulin a high alert med
any error can lead to death
why is IV anticoagulant (heparin) a high alert med
can cause severe bleeding
heparin requires
a PTT to check the level
insulin drips require
a blood sugar (glucose) level to titrate appropriately
if the PTT is high
the blood is too thin and you can not give heparin
if the PTT is low
the patient is prone to clotting
what is the only kind of insulin that can be given continuous IV infusion
regular insulin
insulin drips are given to patients with
hyperglycemia
NEVER GIVE INSULIN TO PATIENT WITH BS UNDER 60
heparin protocol can
differ per facility
titration
adjusting med dosage for max benefit without adverse effects
heparin titration is based off of what lab result
PTT levels
heparin purpose
prevent blood clots (anticoagulant)
what is a “loading dose”
bolus of heparin initially, followed by drip rate
high alert medication identification
red label
PCA pump
patient controlled analgesia pump (pain control)
what 3 things does a PCA pump have
- prescribed rate
- lock-out time
- hourly max dose
what is a PCA pump for
IV method of pain management that allows the patient to self administer pain meds
basal rate=
amount of medication infused continuously per hour
what is the point of lock-out time
preventing overdose
medications that could be administered by the PCA pump
morphine, fentanyl, demerol, etc
what does it mean to give a patient a bolus of fluids
giving a large amount of fluid over a short amount of time
