Final answer:
In pediatric patients, the deltoid muscle is typically used for IM injections starting from the age of 3 years old. The maximum volume for deltoid injections is generally 1 mL.
Step-by-step explanation:
In pediatric patients, the deltoid muscle is typically used for intramuscular (IM) injections starting from the age of 3 years old. It is important to note that the deltoid muscle may not have sufficient mass in younger children to safely administer IM injections, so other sites such as the vastus lateralis (thigh muscle) or ventrogluteal (hip muscle) may be preferred in younger age groups.
Maximum Volume:
The maximum volume that can be safely injected into the deltoid muscle depends on the age and size of the child. General guidelines suggest that for children aged 3-18 years, a maximum volume of 1 mL can be injected. However, it is crucial to consider the child's body weight and the medication being administered to ensure safe dosing.
