All of the following are the recommended sites for subcutaneous injections, EXCEPT:

Appeared in: BTSC Staff Nurse 30July-2025

Explanation

The dorsogluteal area is not a recommended site for subcutaneous injections.
This site contains the large sciatic nerve and superior gluteal artery, which can be easily damaged.
Due to the high risk of significant injury, including paralysis, the dorsogluteal site is no longer recommended even for intramuscular injections, let alone subcutaneous ones.
Subcutaneous injections require fatty tissue, and while the gluteal area has fat, the specific dorsogluteal landmarking puts underlying critical structures at risk.

Option A: The anterior thigh is a standard, recommended site for subcutaneous injections.
Option C: The anterior abdomen is a primary recommended site for subcutaneous injections.
Option D: The upper arm (specifically the outer posterior aspect) is a recommended site for subcutaneous injections.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomical sites for subcutaneous medication administration as background academic context rather than a clinical decision trigger.
Proper site selection is a fundamental nursing skill to ensure patient safety and medication efficacy. Using an incorrect site can lead to severe complications.
Nurses must educate patients who self-administer injections on the importance of site rotation to prevent lipohypertrophy (lumps of fat) or lipoatrophy (loss of fat), which can impair medication absorption.
What if? If a patient is extremely thin (cachectic) with very little subcutaneous fat, the nurse should gently pinch the skin to raise the adipose tissue and may need to use a shorter needle or a 45-degree angle of insertion to avoid injecting into the muscle. The upper abdomen is often the best site in such cases.

How to Approach the Question

First, identify that the question is a negative-framing question because it uses the word 'EXCEPT'. This means you are looking for the option that does not fit with the others.
Recall the standard, recommended anatomical sites for administering subcutaneous (SC) injections.
The common sites are the abdomen, the outer posterior aspect of the upper arms, and the anterior thighs.
Evaluate each option against your knowledge of correct SC sites.
Anterior thigh, anterior abdomen, and upper arm are all correct sites.
The dorsogluteal area is the outlier. This site is known for its risks (sciatic nerve) and is not used for SC injections. Therefore, it is the correct answer to the 'EXCEPT' question.
