Slide 6: 

Right patient Right Route Right Approach Right Recording

Slide 7: 

2. Practice asepsis 3. Nurses who administer medications are responsible for their own actions. Question any order that you consider incorrect. 4. Be knowledgeable about medications that you administer.

Routes of Drug Administration. : 

Routes of Drug Administration. Oral Route Forms: a) solid: tablet, capsule, pill, powder. b) liquid: syrup, suspension, emulsion. Enteric coated tablets should not be crushed before administration.

Slide 12: 

Suspensions are never administered intravenously. If the patient vomits within 20 – 30mins of taking the drugs, notify the physician. Do not readminister the drug without a physicians order.

Slide 13: 

2. Sublingual- drug placed under the tongue, where it dissolves. 3. Buccal- medication is held in the mouth against the mucous membranes. of the cheek until the drug dissolves.

Slide 14: 

4. Topical a) Dermatologic- lotions, liniments, ointment, pastes and powders. b) Ophthalmic- instillations and irrigations. c) Otic

Slide 15: 

d) Nasal e) Inhalation f) Vaginal- tablet, cream, jelly, foam, suppository 5. Rectal- (objectionable taste or odor)

Slide 16: 

6. Parenteral- administration of medications by needle. a) Intradermal (ID)- under the epidermis (into the dermis). b) subcutaneous (SC)- in the subcutaneous tissue (also, hypodermic)

Slide 17: 

c) intramuscular (IM)- into the muscle. d) intravenous (IV)- into a vein. e) intraarterial- into an artery. f) intraosseous- into the bone.

Intradermal (ID) : 

Intradermal (ID) Intradermal (ID)- indicated for allergy and tuberculin testing and for vaccination. > SITES: - inner lower arm *Left arm- for tuberculin test * Right arm- for all other test

Slide 19: 

Upper chest Back, beneath the Scapula What to observe? - less hairy Needle gauge # - less pigmented - #25,26,27 - less vascularized Needle length - less keratinized - 3/8”, 5/8”,1/2”

Slide 20: 

Angle- 10 to 15 degrees angle, bevel up Inject a small amount of drug to form a wheal or bleb. Do not massage the site of injection

Subcutaneous (SC) : 

Subcutaneous (SC) Subcutaneous (SC)- drug administered subcutaneous are as follows: = Vaccines, pre-operative medications, narcotics, insulin, heparin.

Slide 22: 

SITES: - outer aspect of the upper arm - anterior aspect of the thigh - abdomen - scapula areas of the upper back. - upper ventrogluteal and dorsogluteal area.

Slide 23: 

Needle angle- 45 degrees angle if 5/8” needle -90 degree angle if ½” needle (heparin and insulin)

Intramuscular (IM)- ordered for the following reasons: : 

Intramuscular (IM)- ordered for the following reasons: Rapid absorption because of rich blood supply Muscles can take a greater volume of fluid without discomfort ( adult can tolerate up to 3ml in large DG or VL muscles) Medications that irritating may safely be given by intramuscular injection.

Slide 25: 

Needle length- 1” , ½”, 2”, (3” if obese) Needle gauge- 20, 21, 22 , 23 SITES: Ventogluteal site- uses gluteus minimus muscle. Dorsogluteal site- use gluteus medius muscle.

Slide 26: 

- not to be used for children <3 yrs. of age unless the child has been walking for 1 yr. - avoid hitting the sciatic nerve

Slide 27: 

3. Vastus Lateralis Site- recommended site of injection for infants. - located at the middle third of an anterior lateral aspect of the thigh.. 4. Rectus Femoris Site- anterior aspect of the thigh.

Slide 28: 

5. Deltoid site- Z-tract injection(variation) = for parenteral iron preparation. - to seal the drug deep into the muscle. - prevent permanent staining of the skin.

Intravenous (IV) : 

Intravenous (IV) Intravenous (IV)- direct IV, IV push, IV infusion. - most rapid route of absorption of medication.
