The nurse is preparing to administer an intramuscular (IM) injection into the client's vastus lateralis. The nurse is correct in identifying the landmark by
A. palpating to find greater trochanter and knee joints; divide the vertical distance between these two landmarks into thirds; inject into the middle third.
[42%]
B. locating the acromion process; inject only into the upper third of muscle that begins about two fingerbreadths below the acromion.
[12%]
C. locating the greater trochanter, iliac tubercle, and iliac crest; places palm over the greater trochanter, over iliac tubercle, along the ileum; inject into center of V formed by the fingers.
[39%]
D. displacing the skin by pulling the skin down or to one side about 1 inch with the non-dominant hand before administering the injection.

Explanation
Choice A is correct. This is the appropriate anatomical landmark for giving an IM in the vastus lateralis. To locate the vastus lateralis, palpate to find greater trochanter and knee joints; divide vertical distance between these two landmarks into thirds; inject into the middle third.
Choices B, C, and D are incorrect. Locating the acromion process is a landmark involved with giving an IM in the deltoid muscle. Locating the greater trochanter, iliac tubercle, and iliac crest is involved in giving an IM ventrogluteal. Displacing the skin by pulling the skin down or to one side about 1 inch is relevant to the Z-track technique, commonly used when giving an IM injection. This technique does not locate the appropriate anatomical location of the vastus lateralis.

Additional Info
A key advantage of using the vastus lateralis is that an intramuscular (IM) injection may be given if the client is supine, side-lying, or sitting. Aspiration for routine injections into deltoid or vastus lateralis is not indicated because there are no large blood vessels in these locations.
