Routes of Administration 💉💊 💉 Intradermal (ID): 10–15° → A small bleb is expected after an intradermal injection 💉 Subcutaneous (SUBQ): 45° - 90° → Use 90° with adequate fatty tissue; 45° if the patient is thin 💉 Intramuscular (IM): 90° → The Z-track method helps prevent leakage and irritation 💉 Intravenous (IV): 10–30° → Fastest absorption; a lower gauge number means a larger catheter 🧠 Absorption speed (slow → fast): ID → SUBQ → IM → IV Save this for skills checkoffs NCLEX review 📚 The
