Intraperitoneal injections are administered into which abdominal area?

Intraperitoneal injections are administered into which abdominal area?

• A. Lower right
• B. Lower left
• C. Upper right
• D. Upper left

Answer: (A)

Intraperitoneal injections place fluid into the peritoneal cavity, so the site is chosen to access that space while minimizing risk to surrounding organs. The lower right quadrant is used because it provides a safer window into the peritoneal cavity: major organs like the liver are largely in the upper right, and the stomach and spleen are higher in the abdomen, so targeting the lower right area reduces the chance of puncturing them. In practice, this location also tends to give a straightforward path into the peritoneal space and helps the injected material disperse appropriately.
