Medication Administration Flashcards
Absorption
Is the passage of medication molecules into the blood from the site of medication administration
Factors that influence absorption.
Route of administration, ability to dissolve, blood flow to the site of administration,body surface area, lipid solubility of medication
IV Injection
Produces the most rapid absorption because medications are immediately available when they enter the systemic circulation
Therapeutic effect
Is the expected or predicted physiological response that a medication causes.
Side effects
Are predictable and often unavoidable secondary effects produced at a usual therapeutic dose.
Adverse effects
Unintended, undesirable,and often unpredictable severe responses to medication
Toxic effects
Develop after prolonged intake of a medication or when a medication accumulates in the blood because of impaired metabolism or excretion.
Idiosyncratic reaction
Overreacts or under reacts to a medication or has a reaction different from normal.
Anaphylactic reactions
Life threatening,characterized by sudden constriction of bronchiolar muscles, edema of the pharynx and larynx, and severe wheezing and SOB
Urticaria
Raised, irregular shaped skin eruption with varying sizes and shapes; eruption have reddened margins and pale centers
Pruritus
Itching of the skin; accompanies most rashes
Rhinitis
Inflammation of mucous membranes lining nose; causes swelling and clear, watery discharge.
Pharmacokinetics
Study of how medications enter the body, reach their site of action, metabolize, and exit the body.
Caplet
Shaped like capsule and coated for ease of swallowing
Capsule
Med encased in gelatin shell
Tablet
Powdered med compressed into hard disk or cylinder; addition to primary medication, contains binders, disintegrates, lubricants, and fillers
Enteric-coated tab
Coated tab that does not dissolve in stomach, coatings dissolve in intestine, where med is absorbed
Elixir
Clear fluid containing water and/or alcohol; often sweetened
Aqueous solutions
Substance dissolved in H2O and syrup
Aqueous suspension
Finely divided drug particles dispersed in liquid medium; when suspension is left standing, particles settle to bottom of container
Troche
Lozenge…. Flat, round tab that dissolves in mouth to release medication. Not meant for ingestion.
Aerosol
Aqueous medication sprayed or absorbed in mouth and upper airway . Not meant for ingestion
Sustained release
Tab or capsule that contains small particles of a medication coated with material that requires a varying amount of time to dissolve.
