med admin 1 Flashcards
what is a nurses responsibility related to medication?
to interpret, transcribe, prepare, administer, teach, document, and evaluate pt response
what is the chemical name of a medication? and example
provides an exact description of the medications composition, its molecular structure
(ex: isobutylphenyl propionic acid)
what is the generic name of a medication? and example
given by the manufacturer that first develops the drug, the generic name becomes the official name that the med is listed as (ex: Ibuprofen)
what is the brand or trade name? and example
name that the manufacturer markets the medication (ex: Advil)
what is a generic drug?
contain the same medicinal ingredients as brand name drug
what drug classification is tylonal under?
antipyretic (reduces fever), analgesic (pain reliver)
what drug classification is asprin under?
analgesic (pain reliever), antipyretic(reduces fever), anti-inflammatory (reduces inflammation), platelet aggeration inhibitor (inhibit clot formation)
what are the 4 processes of pharmacokinetics?
- absorption
- disruption
- metabolism
- excretion
ADME… acronym
what is absorption in relation to pharmacokinetics?
where the med enters the body and absorbed into the bloodstream
what are the 2 parts of absorption in the pharmacokinetic cycle?
first pass (phenomenon where a med gets metabolized at a specific part of the body) and
bioavailability (the amount of med available to reach the target cells after metabolism)
what is the first pass in relation to pharmacokinetics?
the phenomenon where a med is metabolized at a specific part of the body
what is bioavailability in relation to pharmacokinetics?
the amount of med to reach the target cells after metabolism to produce its intended effect
what is metabolism in relation to pharmacokinetics?
the breakdown of mediation into inactive/less active forms, at a higher risk of med toxicity if your metabolism is lower (ie. older people)
what is distribution in relation to pharmacokinetics?
the transportation of the medication in the bloodstream to the site of blood action… most meds bind to protein (ex: albumin is made by the liver and people that don’t produce enough albumin have an increased chance of drug toxicity)
what is excretion in relation to pharmacokinetics?
process that meds exit the body, through the lungs, exocrine glands, bowel, kidney, and liver
what organ is the main form of med excretion?
kidneys
what is a drug half-life?
the time it takes for the drug to be 50% eliminated from the bloodstream
what are the 6 types of medication effects?
- therapeutic effect
- side effect
- adverse effect
- toxic effect
- idiosyncratic reaction
- allergic reaction
what is the therapeutic effect with medications?
the intended or desired physiological response of the medication
what is the side effect with medications?
an unintended secondary response could be harmful or harmless
what is the adverse effect with medications?
severe negative response to a drug that promotes immediate discontinuation of taking (ex: coma)
what are toxic effects with medications?
the development of toxicity following prolonged intake of a medication or after it has accumulated in the bloodstream
what is the idiosyncratic reaction with medications?
unpredictable effects which occur when a patient over or under reacts to a medication(ex: Benadryl causes drowsiness in adults but can cause excitement in children)
what are allergic reactions with medications?
an immune response following becoming immunologically sensitive to the initial dose, the next dose then causes a severe reaction (possibly an anaphylactic response)
