Step-by-step explanation:
Intramuscular injections are used to insert the medicine deep inside the muscles. The muscles have a lot of blood vessels so the medications will be directly absorbed into the bloodstream.
A ventrogluteal injection is a kind of injection inserted to the area of hip called as the ventrogluteal site. The length of the needle should be 1 to 1.5 inches so that the needle can penetrate the fat present in the region and allow the medicine to be absorbed at the region. The needle length can be adjusted to a thickness so that it can help in the penetration process.
