Ch. 34.2 Medication Administration Flashcards
Enteral feeding
refers to intake of food via the gastrointestinal (GI) tract. (mouth, esophagus, stomach, and intestines)
Topical administration
refers to administration of drugs onto the surface of the skin or of membranous linings of eye, ear, nose, respiratory tract, urinary tract, vagina and rectum
Sublingual:
Medication placed under the tongue; is dissolvable.
Buccal: Medication
placed between the upper or lower molar teeth and cheek area; is dissolvable – some sources refer to sublingual and buccal as oral.
systemic effects
are defined as those effects occurring in tissues distant from the site of contact between the body and the medical device or biomaterial.
Inhalation
Medications are absorbed rapidly
Usually used for respiratory disease
Pt understanding is important as these medications are used to manage airway. Rescue medications are for immediate relief and are short acting, Maintenance inhalers are used daily to prevent respiratory distress. They must be used correctly to be effective.
spacer; The spacer traps medication released from the MDI; the patient then inhales the drug from the device. Allows more time to the patient to inhale the medication and allows more medication to be absorbed
Rectal Meds
Rectal medications are relatively safe because they rarely cause local irritation or side effects. They are contraindicated in patients with recent surgery on the rectum, bowel, or prostate gland; rectal bleeding or prolapse; and very low platelet counts.
MDI
metered dose inhaler
• An MDI is a small handheld device that disperses medication into the airways through an aerosol spray or mist by activation of a propellant.
BAi
breath-actuated metered-dose inhalers
DPI
dry powder inhalers
• DPIs hold dry powdered medication and create an aerosol when the patient inhales through a reservoir containing medication.
• DPIs require little manual dexterity.
• The device is breath activated; there is no need to coordinate puffs with inhalation.
Nebulization
- is a process of adding medications or moisture to inspired air by mixing particles of various sizes with air.
- Droplets in the mist are much finer than those created by MDIs or DPIs.
- A face mask or a mouthpiece held between the teeth delivers nebulized mist.
- Ex. broncodialators, corticosteroids
Irrigation
Medications used to wash out a body cavity, delivered with a stream of solution (sterile water, saline, or antiseptic)
Asepsis or clean technique, depending on location
Bladder irrigations
• a procedure used to flush sterile fluid through your catheter and into your bladder
… 3 way foley…. 3L bag bladder irrigation (normal saline)
Connect to input so that a slow constant flow of saline is cleansing out bladder. May be used for bleeding, increased sediment and mucous
Parenteral administration
administration of medications by injection
Subcutaneous injection
Injection into tissues just under the dermis of the skin
Intramuscular (IM) injection:
: Injection into the body of a muscle
Intradermal (ID) injection:
Injection into the dermis just under the epidermis
Intravenous (IV) injection or infusion:
Injection into a vein
Lurer-Lok
- secure stew like connection
- requires a needle that twists in place and prevents the needle from slipping out of the syringe. It is the most common type of syringe. A non Luer-Lok is also called a slip tip.
Slip Tip slip
or push-on connection
Eccentric Tip
off center tip used for surface veins or artery injections
Catheter tip:
longer and tapered slip tip designed for irrigation or with tubing
Tuberculin syringes
are 1ml syringes that are useful for preparing small doses. They have an attached needle
Ampules
glass container with a constricted neck that contains a single liquid dose of medication
Top must be snapped off at the coloured ring and filter needle must be used to prevent aspirating glass fragments into the syringe.
The needle is changed once the medication is drawn up.
Use for medications that need to be protected from light, air, humidity.
If there is a dot, should be facing upwards when snapped. Use an unopened alcohol swab to grasp the top and break away.
Vials
– may be single does or multi dose. Have a cap that protects the robber stopper. May be a powder that will have special instructions describing how it is to be reconstituted with saline or distilled water. May need to roll gently to fully dissolve powder
Multidose vials need a label that record the time of opening. If mixed date of mixing and concentration are necessary as well.
