PHARM QUIZ 1 - Intro to Pharm Flashcards
drug
any chemical that can affect living processes
pharmacology
the study of drugs & their interactions with living systems
clinical pharmacology
the study of drugs in humans
therapeutics
the use of drugs to diagnose, prevent, or treat disease or to prevent pregnancy
3 properties of an ideal drug
- effectiveness (solves problems)
- safety (ideally has no side effects, not possible)
- selectivity (treat what it is intended for)

ideal drug considerations
- reversible action - able to be metabolized by the body or chemically nullified
- predictability - knowing how the pt will respond
- ease of administration - convenient route, low number of doses/day
- freedom from drug interaction - to not intensify/ reduce effects of other drugs
- low cost - easily affordable
- chemical stability - indefinitely retain effectiveness & potency
- simple generic name - easy to recall/ pronounce
what is the therapeutic objective of drug therapy?
to provide maximum benefit while doing minimal harm
toxicity
too much of a drug
what happens when too little of a drug is administered?
it is not effective
what factors can cause drug variation?
- age
- gender
- weight
- poor liver/ kidney function
- multi-drug or food interactions
pharmacokinetics
how the drug moves through the body
pharmacodynamics
how the drug affects the body

what must be done before doing any med administration?
- vitals
- head to toe assessment
- establish a baseline
goals of preadministration assessment
3
- collect baseline data - vitals, pain assessment, head to toe
- identify high-risk pts - liver/kidney disease
- assess pt’s capacity for self-care - learning disabilities, alzheimers/ mental condition, physical disabilities
why do we collect baseline data?
- safety
- response
- identiying high-risk pts
- assesing a pt’s self-care ability
what does baseline data include?
- pt h&p
- lab results
- bp & vitals
- bgl
- ht/wt
high risk pts
- liver impairment (primary organ that metabolizes drugs) & kidney impairment (filters drugs) - VERY IMPORTANT
- genetic factors
- drug allergies - VERY IMPORTANT
- pregnancy
- elderly - slower metabolism, drugs stay longer
- pedi - slower metabolism, decrease dosage
can RN make a medical diagnosis?
no
we can use nursing judgement to have a working nursing diagnosis
(preventions/plan)
