A 45-year-old male patient requires an intramuscular injection of a prescribed medication. You have selected the dorsogluteal site for the injection. Which of the following steps will help you identify the correct location for needle insertion?
Palpate the sacrum and inject into the area halfway between the sacrum and the greater trochanter of the femur.
Divide the buttock with a horizontal and a vertical line intersecting at the coccyx and inject into the quadrant nearest to the greater trochanter.
Locate the posterior superior iliac spine and divide the buttock into four equal quadrants, then inject into the lower inner quadrant.
Locate the posterior superior iliac spine and the greater trochanter, then inject into the upper outer quadrant above and lateral to an imaginary line between these two landmarks.
