Guide Latest Version 2023/2024 NURS 5334 Final Study Guide Prescribing basics - --Prescribing is regulated by state BON Proper RX - --Providers name and address, Telephone DEA Pt name/DOB/Addres Name of Drug, strength, SIG(directions) with indication/Route and frequency, Quantity and signature. Drug Schedules: Most addictive to least - --1: Heroin,LSD, MJ 2: hydrocodone, cocaine, Methamphetamine, methadone, oxycodone, meperidine, fentanyl, adderall, ritalin 3: codeine, ketamine, testosterone 4: xanax, valium, soma, ambient, tramadol 5: antidiarrheal, antitussives, lomotil, lyrica Pharmicodyamics - --The effects of drug on the body. Receptors are large molecules usually proteins, that interact and mediate the action of drugs agonist - --produce receptor stimulation and a conformational change every time they bind. Do not need all available receptors to produce a maximum response Partial agonist - --drugs that have properties in b/w those of full agonist and antagonist. They bind to receptors but when they occupy the receptor sites, they stimulate only some of the receptors. antagonist - --drugs with affinity for a receptor but with no intrinsic activity. Affinity allows the antagonist to bind to receptors, but lack of intrinsic activity prevents the bound antagonist from causing receptor activation. The block action of drugs (ex. Narcan) Bioavailabity - --% of administered dosage of the drug that survives the first pass through the liver and reaches the blood stream half life - --Time required for the amount of a drug in the body to decline by 50%, drugs with shorter half lives must be administer frequently. 4.5-5.5 times the half life to get steady state and to be limited from the body what the body does to the drug - --absorption, distribution, metabolism, excretion Distribution
