@gethelpwithproctoredexam: 1. Intramuscular (IM) Injection • Angle: 90° (straight) • Where the drug goes: Muscle layer Explanation: The needle goes straight through the skin into the muscle. Muscles have good blood supply, so drugs are absorbed fairly quickly. Examples in veterinary practice: Antibiotics, vitamins, vaccines. 2. Subcutaneous (SC) Injection • Angle: about 45° • Where the drug goes: Under the skin (fat layer) Explanation: The needle enters the fat layer between skin and muscle. Drug absorption is slower than IM. Common in animals: Vaccines, insulin, fluids. In animals, the skin is often lifted (tenting the skin) before injecting. 3. Intravenous (IV) Injection • Angle: about 25° (very shallow) • Where the drug goes: Directly into the vein Explanation: The needle enters a blood vessel, so the drug goes directly into the bloodstream and works immediately. Common uses: Emergency drugs, IV fluids, anesthesia. #injections #bodytransformation #nurse #studynotes #injectables
