The ventrogluteal site is used for which type of injection?

• A. Subcutaneous
• B. Intramuscular
• C. Intravenous
• D. Intradermal

Answer: (B)

The ventrogluteal site is used for intramuscular injections because it lies in a thick, well-developed muscle (gluteus medius with nearby gluteus minimus and tensor fasciae latae) that provides a strong, safe area for injecting medication into muscle tissue. This location is also away from major nerves and blood vessels, notably the sciatic nerve, which reduces the risk of nerve damage or vascular injury. The result is a reliable site for absorbing medications quickly from muscle, and it can accommodate larger volumes. In contrast, subcutaneous injections go into fatty tissue just beneath the skin, which is not the target here; intramuscular injections, by definition, penetrate into muscle. Intravenous injections are delivered directly into a vein, not muscle, and intradermal injections are shallow, into the dermis layer of the skin. So the ventrogluteal site best fits the intramuscular route. To locate it, place the palm on the greater trochanter with fingers pointing toward the anterior superior iliac spine and the middle finger toward the iliac crest; the injection is given in the center of the triangle formed by the hands.
