Medication Administration Flashcards
to administer medications safely; what must nurses have an UNDERSTANDING OF? (7)
- HEALTH CARE
- PHARMACOLOGY
- PHARMACOKINETICS
- LIFE SCIENCES
- PATHOPHYSIOLOGY
- HUMAN ANATOMY
- MATHEMATICS
defintion of PURE FOOD & DRUG ACT
- requires MEDS to be FREE of impure products
describe the FDA; FOOD & DRUG ADMINISTRATION
enforces MEDICATION LAWS that ensure that medications on the market go through VIGOROUS TESTING before being sold to the public
describe the MEDWATCH PROGRAM
- type of VOLUNTARY PROGRAM
- encouragement of REPORTING when meds, products or medical events cause SERIOUS HARM to a patient
what are other MEDICATION LEGISLATIONS to consider?
- STATE & LOCAL REGULATION of medications;
ex. CA Department of Health - HEALTH CARE INSTITUTIONS & MEDICATION LAWS
ex. Kaiser, Scripps, Palomar - MEDICATION REGULATIONS & NURSING PRACTICE
ex. SON
what are the types/classifications of MEDICATION NAMES?
- CHEMICAL
- GENERIC/OFFICIAL NAME
- TRADE/BRAND/PROPRIETARY (TM)
definition of NPAS
- known as the STATE NURSE PRACTICE ACTS
- defines the SCOPE OF NURSE’S professional functions & responsibilities
definition of CHEMICAL MEDICATION NAME
- this is RARELY USED in medication admin
- gives the EXACT DESCRIPTION of medication COMP + MOLECULAR STRUC
definition of GENERIC MEDICATION NAME
- known as the OFFICIAL NAME
- from the MANUFACTURER when first developed
- listed in U.S. PHARMACOPEIA
- ex. acetaminophen
definition of TRADE/BRAND/PROPRIETARY NAME
- name of the MARKET DRUG the manufacturer is selling
- EASY TO SPELL & REMEMBER
- ex. tylenol
how are MEDICATIONS CLASSIFIED?
- on its EFFECT on the BODY SYSTEM
- the type of SYMPTOMS the medication relieves
- the medication’s DESIRED EFFECT
what does PO stand for?
by mouth
what are the types of ORAL (PO) MEDICATION FORMS?
- SOLID; tablets, capsules, pills
- LIQUID; syrup, suspension, elixir
- OTHERS; lozenge / aerosol
definition of PHARMACOKINETICS
the study of how medications enter the body, reach the site of action, metabolize, and exit the body
definition of ABSORPTION
- when medication molecules pass from blood to the SITE of needed administration
- has factors considered from its specific ROUTE, END SITE, BSA, and LIQUID SOLUBILITY
what are some FACTORS that can influence ABSORPTION?
- ROUTE OF ADMINISTRATION
- the ABILITY of a MEDICATION to DISSOLVE
- BLOOD FLOW TO SITE (greater the vascularity = the faster the flow!)
- BSA
- LIQUID SOLUBILITY
what are the FASTEST to SLOWEST ROUTES OF ADMIN?
- INTRAVENOUS (IV)
- INTRAMUSCULAR/SUBQ (IM/SQ)
- SKIN & PO
what can medications bind to that can DECREASE its effect?
albumin
definition of DISTRIBUTION
- follows after ABSORPTION
- DISTRIBUTION towards other TISSUES, ORGANS, & SPECIFIC SITE
what FACTORS INFLUENCE DISTRIBUTION?
- CIRCULATION; CHF patients
- MEMBRANE PERMEABILITY; specific BBB - only passes FAT-SOLUBLE MEDS
- PROTEIN BINDING (albumin)
definition of METABOLISM
- process of BIOTRANSFORMATION; use and influence of enzymes that begin to DETOXIFY, BREAK DOWN, & REMOVE ACTIVE CHEMICALS
- begins to METABOLIZE medication to more of an INACTIVE FORM/LESS POTENT
- preparation for EXCRETION
- typically occurs in the LIVER
definition of EXCRETION
- the EXITING OF MEDICATIONS
- typically occurs in the KIDNEYS
(can be excreted through liver, bowels, lungs, exocrine glands) **depends of medication really
what happens if a patient has LIVER OR KIDNEY ISSUES?
- have a greater risk of developing GREATER TOXICITY due to medications
therapeutic effect
the EXPECTED OR PREDICTED physiological response
adverse effect
the UNINTENDED, UNDESIRABLE, OR UNPREDICTABLE response
side effect
a PREDICTABLE, UNAVOIDABLE secondary effect
toxic effect
the ACCUMULATION OF MEDICATION within the bloodstream
- often due to result of IMPAIRED METABOLISM & EXCRETION
idiosyncratic reaction
an UNPREDICTABLE OVERREACTION, UNDERREACTION, or really just a DIFFERENT REACTION THAN NORMAL
urticaria
- also known as HIVES
- irregularly shaped eruptions; red margins / pale centers
pruritus
the ITCHING of the SKIN; comes with rashes
rhinitis
the INFLAMMATION of the MM lining
- swelling + watery discharge
allergic reaction
- this is DIFFERENT FROM SIDE EFFECTS
- type of UNPREDICTABLE REACTION
medication interactions
where ONE MEDICATION MODIFIES the ACTION OF ANOTHER
- type of SYNERGISTIC EFFECT – combined effect is greater than singular
medication tolerance
- where MORE MEDICATION is required to achieve the same THERAPEUTIC EFFECT
- more increased dosages of the med
medication dependence
- known as ADDICTION
- can be either PHYSICAL (showcase of withdrawal symptoms) or PSYCHOLOGICAL
what is the TIMING OF MEDICATION DOSE RESPONSES?
THERAPEUTIC RANGE:
consists of the lowest MEC to highest TOXICITY
definition of MEC
MINIMUM EFFECTIVE CONCENTRATION (MEC):
- the PLASMA LEVEL of a medication below which the effect of the MEDICATON DOES NOT OCCUR
definition of TOXIC CONCENTRATION
- TOXIC CONCENTRATION:
level at which TOXIC EFFECTS OCCUR
definition of PEAK & TROUGH
PEAK - highest level in our therapeutic range
TROUGH - lowest level in/entering MEC
definition of BIOLOGICAL HALF-LIFE
time it takes for excretion processes to LOWER the serum medication concentration by 1/2
