What is the preferred site for intramuscular injections in infants and children?

• A. Deltoid muscle
• B. Vastus lateralis
• C. Gluteus maximus
• D. Rectus femoris

Answer: (B)

The vastus lateralis is considered the preferred site for intramuscular injections in infants and children due to several key factors. This muscle is located in the thigh and is well-developed even in very young patients, making it a safe and effective site for administering medications. Using the vastus lateralis minimizes the risk of injury to major nerves and blood vessels, which is critical when dealing with smaller and more vulnerable patients. Additionally, this site provides a larger muscle mass, allowing for the effective absorption of medications with less discomfort. While the deltoid muscle can be used in older children and adults, it is not fully developed in infants, making it less suitable for injections in that age group. The gluteus maximus can pose risks of damaging the sciatic nerve, and while the rectus femoris could be used, it is less commonly employed for routine injections compared to the vastus lateralis. This preference is backed by healthcare guidelines and practices focused on safety and efficacy in pediatric care.
