Which injection site is recommended for intramuscular administration of 3 mL of medication in a well-developed adult female?

1. Vastus lateralis

2. Deltoid

3. Dorsogluteal site

4. Ventrogluteal site

The correct answer is: Ventrogluteal site

The ventrogluteal site is the preferred injection site for administering larger volumes of medication, such as 3 mL, in a well-developed adult. This site is located away from major blood vessels and nerves, making it a safer option for intramuscular injections. It is also well-suited for larger volumes due to the muscle mass in this area. When administering medication, especially in well-developed adults, the ventrogluteal site provides a deeper muscular area that can accommodate increased volume without the risk of injury or complications often associated with other sites. The other options, while viable for certain situations, may not be appropriate for this specific volume. For example, the deltoid muscle is generally limited to smaller volumes, typically not exceeding 1 mL due to its size and proximity to the shoulder joint and radial nerve. The vastus lateralis is often used for infants and small children, and while it can accommodate larger volumes, the ventrogluteal site is generally preferred for adults due to its lower risk factors. The dorsogluteal site is no longer recommended as a preferred site due to the risks associated with sciatic nerve injury and vascular complications. In summary, the ventrogluteal site is recommended for
