| pharmacokinetics are used when | timing medication administration, selecting routes, and observing client responses |
| absorption | the passage of mediation molecules into the blood from the site of administration |
| factors that influence absorption | route of administration, ability to dissolve, blood flow to area, body surface area, lipid solubility |
| distribution | the rate and extent of distribution depends on the physical and chemical properties of medicine and the client's physiology |
| things that affect drugs ability to be distributed to where we want it to be | circulation, membrane permeability, protein binding, metabolism, excretion |
| metabolism | occurs after the medication reaches the sit of actions, becomes metabolized into a less active or inactive form |
| biotransformation deals with | liver, kidneys, blood, and intestine |
| excretion | the chemical makeup of the medication determines the organ of excretion |
| kidney, liver, lungs, exocrine roles of excretion | kidney-main organ, liver-distributes med, lungs -what meds are excreted through the lungs, inhalers, oxygen, anathesia. exocrine-sweating out meds, |

| rhinitis | inflammation of mucous membranes lining of nose; causes swelling and clear, watery discharge |
| wheezing | constriction of smooth muscles that surround bronchioles, occurs mainly on inspiration and can lead to airway obstruction |
| angioedema | short-term subcuaneous or submucosal swellings of the face, neck, lips, larynx, hands, feet, genitalia, or viscera |
| synergistic effect | med interaction; when 2 meds are combined and one is greater than the effects of the meds when given separatley |
| half-life | the times interval required for the body's elimination processes to reduce the concentration of the drug in the body by one-half |
| intradermal | injection into the dermis just under the epidermis |
| subcutaneous | injection into tissues just below the dermis of the skin |
| 1 ounce = 1 tablespoon = 1 teaspoon = | 1 ounce= 30 ml; 1 tablesppon = 15 ml; 1 teaspoon=5 ml |
