N 160: Chapter 3 (terms/objectives)
Terms in this set (35)
a tablet that is placed in the buccal pouch (between the cheek and gum) to dissolve quickly
solid dosage forms in which the drug is usually encased in a shell of hard/soft gelatin
a clear hydroacloholic mixture that is usually sweetened or otherwise pleasantly flavored.
created when two liquids that do not mix well are combined and one liquid distributes uniformly thru the other
uses the GI tract for the ingestion and absorptions of drugs, most common is orally but could be permitted rectally
a wax-like layer that is used on some tablets to avoid dissolution in stomach (MADE TO BE DISSOLVED IN SMALL INTESTINES)
drug administration requires a surgeon to insert a catheter into an artery leading directly to the targeted area
injection is performed only by a skilled practitioner and involves injecting a drug into a joint
injections are made into the dermis just below the epidermis (ex. TB shot 0.5mL)
drug movement directly into blood stream after injection into muscle mass, absorption depends on he type of solution, size and circulation of muscle (deltoid 1ml, dorsogluteal, ventrogluteal, rectus femoris, vastus lateralis)
a drug is delivered into the cerebrospinal fluid (epidural), indicated when it is impossible to achieve sufficient plasma levels for diffusion
administered directly into bloodstream, absorption is instantaneous and complete, infused as a bolus or IV push or IV drip, Allows administration of large V of drug, avoid tissue irritation, circumvents impaired circulation, dangerous because unable to slow or stop distribution
adding secondary tubing, an intravenous line through which medication is introduced or administered in the body of the patient through vein. This medication can be anything from diluted medicine for any disease or energy giving solution or even an antibiotic for fast recovery
direct administration into a vein/ an established drug infusion lock of a concentrated drug in a very small amount of solution (usually 1-2mL)
a specific area
it circulates throughout the entire body and can exert an effect anywhere in the body
means it goes into a specific part like an inhaler, eye drop, ear drop.
avoids the GI tract and is associated with all forms (IM, SC, IV, ID,Intra-articular, Intra-arterial, intrathecal)
drugs are administered under the skin into fat and connective tissue (0.3mL), non-irritating, low volume, highly soluble drug use, one set less rapid than IM, more rapid than ID (upper lateral arm, anterior thigh, abdomen, midback (below scapula)
tablets placed under the tongue to dissolve
a drug preparation consisting of two agents; a finely divided solid dispersed within a liquid.
tablets formulated to release a drug slowly over an extended period, rather than rapidly
a concentrated solution of sugar in water
a solid dosage form that is prepared by compressing or molding a drug into various sizes and shapes
applied to the skin or mucous membrane, absorption occurs readily, drugs quickly enter the vascular system and GI secretions do not destroy them. Used for Localized or system effects through transdermal or transmucosal effects
used to achieve a local effect in the mouth/pharynx (A small, circular medicinal lozenge)
what are the 6 rights of drug administration?
-drug (make sure right drug for patient)
-dose (cannot be changed, only dr can
-documentation (always chart down everything you do)
-patient (correct pt, check arm band and 2 other forms of verification)
-route (CANNOT CHANGE!-ex. baby story)
-time (some meds are timed, need to stick with sched)
Benefit and risk of Enertal drugs
easy to administer, most complex of all administration forms, more dense drug... longer it takes to absorb, cant be opened/crushed/chewed
Benefit and risks of Parenteral drugs
Avoids GI tract, Injections... which work faster
benefit and risks of topical drugs
used for localized use on eyes, ears, nose, rectum and vagina. Can be either localized of system effect. Absorption occurs readily. Drugs enter the vascular system
What critical step must be done prior to administering medication via a nasogastric tube?
must be liquid/crushed or in a liquid vehicle.
identify the anatomic landmarks for intramuscular (IM) drug administration (5)
Identify the appropriate areas of the body for subcutaneous drug administration (4)
1. Supper lateral arm
2. anterior thing
4.midback, below scapula
which parenteral technique poses the greatest risk or benefit to a patient?
what is the purpose of an enteric coated drug?
To resist the acid environment of the stomach so that it can be administered in the Small intestines, to protect acid labile drugs to provide a sustained release dose
