A patient is ordered to receive a medication via the subcutaneous route. Which of the following sites is most appropriate for this type of injection?

Deltoid muscle

Forearm

Abdomen

Vastus lateralis

Answer and Explanation

The Correct Answer is C

A. Deltoid muscle: The deltoid is primarily used for intramuscular injections, not subcutaneous injections. Using it for subcutaneous medication may result in improper absorption and increased discomfort.

B. Forearm: The forearm is generally reserved for intradermal injections, such as allergy or tuberculosis testing, and is not ideal for subcutaneous medication due to limited subcutaneous tissue.

C. Abdomen: The abdomen is the preferred site for subcutaneous injections because it has a large, easily accessible layer of adipose tissue, allowing consistent and predictable absorption of medications like insulin and heparin.

D. Vastus lateralis: The vastus lateralis muscle, located in the thigh, is typically used for intramuscular injections. It is not preferred for subcutaneous administration as absorption may be less consistent.
