Veterinary Medical Applications Lesson Title: Injections TEKS Addressed in Lesson: 130.6. (c)(6) Lesson Objectives: Determine injection sites Identify various routes of administering medication Demonstrate proper calculations based on animal weight Use precision to fill a syringe Assess animal health in order to determine proper medication to be administered Key Terms/Vocabulary Aspirate- to pull back on the needle to check for blood Inoculate- treat (a person or animal) with a vaccine to produce immunity against a disease. Intramuscular- an injection given into the muscle Intravenous- an injection given into a vein Sharps- needles Subcutaneous- an injection given below the skin SubQ- abbreviation meaning subcutaneous Interest Approach/Anticipatory Set - Have several needle and syringe sizes displayed. Ask students to make assumption as to why the various sizes are necessary. Have students attempt to draw medication into the syringe with no air bubbles. Teaching Plan and Strategy Presentation of New Material Teacher Lecture to include: Types of medication Injection Sites-discuss things to consider when choosing injection sites such as (show animals or spoilage of quality meat areas) Types of syringes/parts of syringes Injection types Withdrawal Periods Calculating dosages Activity/Application/Student Engagement/Laboratory Students should fill in chart during teacher lecture Type of Injection Intramuscular Subcutaneous Intraveneous Interperitoneal Nasal Oral Abbreviati Site of Steps to administering on Injection the injection Lab Activity Students should observe several types and sizes of needles Practice drawing liquid into syringes Practice giving injections- This exercise can be done with bananas or oranges or two baggies, one inside the other, the inner baggie should be filled with water and the outer bag should contain flour. The flour bag represents the skin, the flour represents subcutaneous tissue and the inner baggie represents the muscle. (chicken breats/thighs can also be used for this activity) Evaluation/Summary Lab Activities Injection Quiz Injections Quiz Determine if the following statements are true or false. Circle your response. 1. T or F You should always inject an animal in the back. 2. T or F Subcutaneous shorts are given under the skin. 2. T or F Intraocular injections are given into the ear canal. 3. T or F To fill a syringe you should first push the air from the syringe into the medication. 4. T or F All injections contain an antibiotic material. 5. T or F Intramuscular shorts are given under the skin. 6. T or F Intraveneous injections should always be given against the flow of blood.
