Q. What are the four types of injections?

Answer

Intravenous (IV): This injection is the fastest way to inject a medication and involves using a syringe to inject a medication directly into a vein. Intramuscular (IM): This injection is given deep into a muscle where the medication is then absorbed quickly by surrounding blood vessels. Subcutaneous (SC): This injection is injected into the innermost layer of the skin called the subcutis or hypodermis, Intradermal (ID): This injection is given directly into the middle layer of the skin called the dermis.
