Medication Administration Flashcards
Steps of pharmacokinetics
- Absorption
- Distribution
- Metabolism
- Excretion
What is pharmacokinetics
The process of how medications work within the
Nursing considerations of medication administration
- timing of administration
- selection of route
- evaluating pt response
7 rights
- patient
- medication
- indication
- dose
- route
- time
- documentation
Therapeutic effect
- the happy place
- expected response
Nitroglycerine (example of therapeutic effect)
decreases cardiac workload and increases myocardial supply
Adverse effect definition
unintended/unpredictable response
High risk patients
- infants
- elderly
- pregnant
- malnourished
- liver/renal failure
- polypharm
Side effect definition
predictable, unavoidable response
Most common side effects
- n/v
- anorexia
- constipation
- diarrhea
- drowsiness
Toxic effect definition
from prolonged/increased intake of med that’s accumulating in the blood
Example of toxic effect
Opioid toxicity= respiratory depression
Idiosyncratic reaction
- overreacts or underreacts to med
- reaction different that normal
Example of idiosyncratic reaction
Child takes Benadryl and becomes excited rather than drowsy
Allergic reaction definition
unpredictable histamine response
If there is an allergic reaction/anaphylaxis, what do you do?
- stop medication
- assess pt, ABC
- report to physician
- communicate w/ pharm
Intolerance definition
side/adverse effect that pt cannot tolerate
ex. n/v, diarrhea
Tolerance definition
receiving an increased dose to achieve same therapeutic effectd
Dependence definition
needing a med to feel better `
Onset definition
time it takes after med to produce a response
Duration definition
during med is present in concentration
Plateau definition
blood serum concentration of med reached and maintained
Peaks definition
highest effective concentration
Trough definition
minimum concentration before next scheduled dose
Half life definition
time it takes for drug to reduce by 1/2
Stat vs now orders
Stat: give once immediately
Now: give once within 90 minutes
Chemo meds administration and effects
Routes: IV, PO
Effects: cancer, birth defects, immune depression
Example of med errors
- inaccurate prescribing
- administering wrong meds
- utilize wrong route
- extra dose
- no administering med
- administering med that pt is allergic to
Med error occurred, what do you do?
- assess pt
- notify provider and develop plan
- inform pt
- notify charge nurse
- notify pharm
- document incident report
Medication reconciliation
- obtain, verify document (current list of meds)
- consider and compare (review what pt is taking preadmission and compare to treatment plan)
- reconcile (compare new orders to current list)
- communicate (make sure list is updated)
