Show Answers:

  1. Types of Medication Orders:
    Standing, PRN, Stat
    • Standing: carried out as specified until cancelled by another order
    • PRN: as needed, when requested or required, often for symptoms
    • Stat: single, one time directive order, carried out immediately (usually an emergency)
  2. Parts of the Medication Order
    • Patient Name
    • Date and Time order was written
    • Name of Drug
    • Dosage of Drug (can be metric, apothecary, or household)
    • Route of Administration
    • Frequency of Administration
    • Signature of person writing order
  3. Documentation
    • MAR: Medication Administration Record (includes orders and administrations)
    • CMAR: Computerized Med Admin Record (more popular)
    • Check correct transcription and question if necessary
    • Document omitted drugs, both intentional and inadvertently omitted
    • --Intentional: (a) fasting before a diagnostic test, (b) problem no longer exists, (c) suspected allergy
    • Document refused drugs: report problem and reason for refusal, patients have a right to refuse, so don’t push
  4. Medication Supply Systems
    • Stock Supply: large quantities on unit, immediately available to nurses
    • ADC: Automated Dispensing Cabinets (computerized)
    • Med Cart: one drawer per patient name on the unit, push cart around to patient rooms
    • Barcodes: on patient, nurse ID, medication container; computer also documents administration
  5. Systems of Measurement
    • Metric: meter (linear), liter (volume), gram (weight)
    • Apothecary: grain (weight); minim, dram, ounce, pint, quart (volume); roman numerals used
    • Household: teaspoon, tablespoon, teacup, glass
  6. The Five Rights (+ 1)
    Assure the right medication is given to the right patient in the right dose by the right route at the right time. Follow with the right documentation. Also added is knowing the right reason for medication. (and check expiration)
  7. 3 Checks of Med Admin:
    Read the label....
    • When the nurse reaches for the container or unit dose package
    • After retrieval from drawer and compare with MAR, or compare with MAR immediately before pouring from a multi-dose container
    • When replacing drug to drawer/shelf or giving unit dose medication to patient
  8. Medication Errors
    • “preventable inappropriate use of medications”
    • Occur when ordered, transcribed, dispensed, administered, monitored
    • Extremely important are the 5 rights and 3 checks
    • Patient Safety comes first:
    • --Check the patient’s condition- note any adverse effects
    • --Notify nurse manager/physician so a course of action can be determined, if necessary
    • --Describe error in patient record and any remedial steps taken
    • --Complete incident form according to agency policy
  9. Type of Medication Errors
    • Inappropriate prescribing
    • Extra, omitted, wrong doses
    • Administration of medication that wasn't ordered
    • Incorrect route or rate of admin
    • Failure to give medication within time interval
    • Incorrect preparation of drug before admin
    • Improper technique of admin
    • Giving a deteriorated drug
  10. Controlled Substances Required Information
    • Locked drawer, only ordered by a physician, record must be kept, check narcotics regularly, usually during shift change (or computer records it), witness and record when discarding is needed
    • --Name of patient
    • --Amount of narcotic used
    • --Hour the narcotic was given
    • --Name of physician who prescribed the narcotic
    • --Name of the nurse who administered the narcotic
  11. Admin of Oral Meds
    • Stomach/Small Intest: solid, liquid powder
    • Special Techniques: damage to teetch, bad taste, children, older adults
    • Enteral Feeding Tube: liquid med or crushable into liquid, room temp only, elevate head to prevent reflux
    • Sublingual/Buccal meds: oral care, drink water prior, dont swallow
  12. Admin of Parenteral Meds
    • Outside of intestines/alimentary canal (injections)
    • Equipment: needles, syringes, needless
    • Intradermal, Subcutaneous, Intramuscular, Intravenous
  13. Admin: Intradermal
    • Into dermis, below epidermis, longest absorption time
    • Inner forearm, or upper back under scapula
    • (3-4 fingers below antecubital space, one hand-width above wrist)
    • Used for tuberculin test, allergy tests, local anesthesia
  14. Admin: SubQ
    • Adipose tissue just below dermis/epidermis
    • slow/sustained rate of absorption
    • Sites: (faster) abdomen, arms, thighs, upper ventral or dorsogluteal areas (slower)
  15. Admin: Intramuscular
    • Faster absorption, depot at site allows for longer duration of effect and sustained release
    • Site is chosen carefully, according to criteria
    • Z-Track Technique: pulling skin taut either one inch to side or spreading skin between 2 fingers, slowing inject medication and steadily withdraw needle, releasing skin (reduces patient discomfort)
  16. Admin: Intravenous
    • Directly into bloodstream, immediate/irreversible effect, most dangerous, sterile technique
    • PCA: patient controlled analgesia for pain management
    • Via Intravenous Solution: added to patient’s infusion solution, requires sterile technique, slow admin over long time period, check for adverse reactions every hour
    • Via IV Bolus or Push: single injection of concentrated solution directly into IV line, delivered very slowly over one minute, according to pharmacist or drug reference
    • Via Intermittent IV Infusion: drug mixed with small amount of IV solution (50-100mL), admin’d over short period at prescribed intervals (ex. q4hr), gravity infusion is drops per minute, infusion pump/smart pump can be used to program infusion rate, needleless (blunt cannula/recessed connection port)
    • -- Piggyback Delivery System: intermittent or additive solution hung higher than primary solution, backcheck valve stops primary when additive is connected (tandem is similar)
    • --Volume Control Admin Set: intermittent solution med is diluted in small amount and admin’d into IV line, used when volume of fluid infused is a concern
    • --Mini-Infusion Pump: (syringe pump) intermittent battery operated, medication mixed in syringe is connected to primary line, delivered by mechanical pressure applied to syringe plunger
    • --Med/Drug Infusion Lock: (“intermittent peripheral venous access device”) needle/catheter, short tube capped with sealed injection port; allows patient freedom (only when med is needed); flush with small amount of saline or heparin

  20. Preparing Medications for Injection:
    Ampule, Vial, Prefilled Cartridge/Syringe
    • Ampule: (glass flask, single dose) discard unused portion, use filter need/discard it/change to appropriate needle, don’t touch needle to rim
    • Vial: (glass bottle with self-sealing rubber stopper) multidose vials use/discard within 24hr (mark date and time of first use), alcohol wipe after each use, inject same amount of air as desired dose
    • Prefilled Cartridge/Syringe: (single dose) clear excess air, eject excess med so only exact dost is given (tubex, carpuject)
  21. Preparing Medications for Injection:
    Mixing Meds in One Syringe
    • (ensure compatibility*)
    • Inject air into both, draw from multiuse vial before single use
    • Draw from a vial before an ampule
    • Discard if cloudy once mixed
    • Insulin: (clear)short acting/ intermediate-acting/ long-acting(cloudy), onset time/peak/duration of effects, scale is U100 (100 units insulin per 1mL) or U25 (infant/child), never shake to mix
  22. Topical:
    • (“inuction”)absorption increased by cleaning site, ointment/liniment that will mix with fat in sebaceous gland lining, applying local heat

    • DPI (dry powder inhaler): breath activated
  29. Patient Teaching
    • Begins upon adminission
    • Tailor to patient’s level of understanding and provide written instructions
    • Teach technique to patient and family; patient demonstrates before discharge
    • Instruct to take as prescribed (length, dose, number of doses)
    • Nurse promotes public/individual education, prevent drug abuse
  30. Pregnancy
    • Adverse effects on fetus; consult physician before any drug use
    • Teratogenic: causes developmental effects on embryo or fetus
    • Drugs cross through placenta and breastmilk
  31. Pediatric Considerations
    • Child is smaller size, weight, body water so dose is lower
    • Infants have immature organs and blood brain barriers
    • Doses are according to BSA (height and weight relationship)
    • Use West Nomogram to calculate BSA
    • Note of medication is per dose or per 24hr period
  32. Geriatric Considerations
    • Decreased mobility, muscle mass, acid production, blood flow (affects absorption)
    • Increase in side effects: liver function, kidney function are impaired
    • More susceptible to drug interactions
    • Patient education is key to success in adherence to medication programs
  33. Nursing Process
    • Nursing history/Medication history Use familiar terms, not medical jargon Health Status and current/past illness
    • Laboratory test results
    • Drug allergiesAssessment continues during and after administration
  34. Nursing Process:
    • Medication Administration Related Diagnoses
    • Ex. “Anxiety related to daily self-injection of insulin”
  35. Nursing Process:
    Outcome Identifying/Planning
    • Expected therapeutic effects will be demonstrated
    • Expected change in symptoms
    • Maintenance of therapeutic blood levels of medication
    • Patient will demonstrate knowledge regarding his/her medication
  36. Nursing Process:
    • Make sure med is taken
    • Offer several drugs separately
    • Never leave meds to be taken later
    • Record admin asap, within 30 min
  37. Nursing Process:
    • Subjective “patient statements”
    • Objective (vitals)
    • Adverse effects
    • Patient drug levels in therapeutic range
    • Patient verbalizes education
