Type and amount of extraneous material that may be safely added to the active ingredient of a drug
Bioavaliability
Amount of a drug that becomes avaliable for activity in the targeted tissue
Efficacy
Effectiveness of each drug used in treatment
Safety and Toxicity
Determined by the number and severity of adverse effects reported after the use of the drug, these standards are constantly monitored and refined
When a narotic is given to a patient, what information must be documented in the Narcotic control book
Name and quality are given
Full name of patient
Name of Doctor
Date
Time
Exact dose

Phenobarbitois
Who regulates narcotics in Canada

What name is given to a medication that identifies its chemical family
Generic

Define pharmacokinetics
The study of how drugs enter the body are absorbed reach their site of action are metabolized and exit the body
Patient's react to the same drugs differently. What are some factors that physician's take into consideration when prescribing a drug.
Age
Physical condition
sex
weight
immune status
Absorption
Process involving the movement of a drug from the site of administration into the systemic circulation in order to provide a desired effect
Distribution
The means by which a drug travels from the blood stream to the target tissue and site of action
Metabolism
The process by which the body transforms drugs into an inactive form that can be excreted by the body
Excretion
Refers to the elimination of drugs from the body after they have been metabolized
Oral
Medications taken by mouth
They travel to the the small intestine where absorption takes place
Sublingual
Drugs can be absorbed immediately by the oral mucosa if they are placed under the tounge or buccal area
Medications absorbed at these sites go directly into the blood stream
Rectal
Drugs may be administered by the rectum if the patient is nauseated and unable to retain oral medication
Parenteral Routes
Medication may be administered intradermally,subcutaneously,
intramusculary,IV
Aminastrated by Doctor or nurse
Contrast might also be used
Intradermal
Usually used for sensitivity testing to a drug or a antigen or for local anaesthesia.
Administered between the layers of the skin
Subcutaneous
Drugs are administered below the epidermis. Absorption through the capilaries is fairly rapid
Intramuscular
Absorption of medication via this route is variable depending on the formation of the drug and which muscle it is injected into.
Intravenous
This route is achieves the most rapid systemic response. It is used if a rapid effect is desired or if a drug can not be injected into body tissues with out damaging them
Tropical Routes
Used for local treatment of skin ailments as well as systemic treatment.
Include
eyes
nose
throat
behind ear
Parenteral drug routes may are
Intramuscular
intravenous
Medications given in imaging departments are most often administered via the route that provides the most rapid response
Intravenous route
Drugs administered by intrathecal route bypass the
blood brain barrier
What is the difference between vial and an ampule
Vial has a rubber stopper in place so allows for multiple doses
Ampule is made of glass and contains a single dose
Two drugs must never be mixed in the same syringe for administration before checking their
Compatibility
You do not have to confirm a verbal order if the order was given to you
True or False
False
Selected drugs in the radiography department may be given at any time by the radigrapher
True or False
False
Standing
Written directions for a specific drug or procedure signed by physican
Written
Written on patients chart
Verbal
Spoken rather then written
Antihistamines
Used to treat allergic reations
Antimicrobials
Treats infections or use as a skin preparation
Anticonvulsives
Prevention of seizures
Antiarrhythmics
Treats chronic cardiac arrhythmais
Analgesics
relieves pain
Sedatives & Tranquilizers
Exert a calming effect often inducing sleep
Antagonists
Local Anesthitics
Eliminates sesation in a certain area
Paralytic agents
A skeletal muscular relaxant
Hypoglycemic agents
Controls the level of glucose in the blood
The purpose of drug metabolism is to
Transform the drug for distribution throughout the body
Drugs given by mouth are generally given in larger doses. This is because
They are absorb more slowly
For a drug to reach its therapeutic effect quickly a physicain migh order
A larger initial dose and later smaller doses
Parenteral drug routes may include
Intramuscular
Intravenous
An abnormally rapid heart beat is called
Tachycardia
A drug that increases the flow of urine is called
Diuretic
Is the symptoms sympathetic response or parasympathetic response
Heart rate increases
Symapathetic nervous system
Is the symptoms sympathetic response or parasympathetic response
Epinephrine is secreted
Sympathetic
Is the symptoms sympathetic response or parasympathetic response
Gastric motility and secretion increase
Parasympathetic
Is the symptoms sympathetic response or parasympathetic response
Salivation increases
Parasympathetic
Is the symptoms sympathetic response or parasympathetic response
Gastric motility decreases
Sympathetic
Factors that may influence that effect of a drug
Age
weight
medication and the patients temperament
Reactions that are expected and prdictable and are not detrimental to health of patient are
