Drug
Any chemical that can affect living processes
Ex. Bleach tie pods, etc
Too much of a drug can be toxic
Pharmacology
The study of drugs and their interactions with living systems
Clinical pharmacology
The study of drugs in human
Therapeutics

Three most Important IDEAL drug
Effectiveness
Selectivity
Safety
(Want the drug to treat what we want it to treat
Is safety possible when taking a drug?
Not possible could make you drowsy, aspirin causes ulcers, etc
Reversible action
Able to be metabolized or chemically nullified
Predictability
Knowing how the patient will respond
Ease of administration
Convenient route, low number of doses per day
We want a drug To provide maximum benefits
While doing minimal harm
Toxicity
Too much of a drug can be toxic
What happens when you give to little of a drug?
It will not be effective
Pharm o kinetics
Explain how a drug moves through the body
Absorption, distribution, metabolism, excretion
Pharmacodynamics
Explain how the drug effects the body
Ex placebo effect
Patients functional state
Nursing process
A decision making process for nurses
APIE
Preassessment and analysis
Planning
Implantation
Evaluation
Three goals for assessment
Collect baseline data
Identify high risk patients
Assess patients capacity for self care
(Vital signs)
Why collect baseline data
Safety response identifying high risk patients
Assessing patients self care ability
Baseline data
Patient history
Physical exam
Lab results
BP/vs
Blood sugar
Height and weight
High risk patients
Liver and kidney impairment
Genetic factors
Drug allergies
Pregnancy
Elderly
Pediatric
Liver
Primary organ that metabolizes drugs
Kidney
Filters out drugs ,
Analysis phases
When we create a nursing diagnosis
Example of a nurses diagnosis
Tell a pt you have shortness of breathe
