What are the two boney landmarks if you are going to give an injection in the ventral gluteal site?
iliac crest and greater trochanter
hyoid and trachea
acromion process and humerus
deltoid and femoral bone
The Correct Answer is A
Rationale:
A. To locate the ventral gluteal site, the nurse places the palm over the greater trochanter (the large prominence of the femur) with the index finger pointing toward the anterior superior iliac spine and the middle finger spread along the iliac crest. The injection site is the triangle formed between these landmarks, which is considered safe because it avoids major blood vessels and nerves, including the sciatic nerve.
B. Hyoid and trachea are structures in the neck associated with breathing and swallowing, not landmarks for intramuscular injection.
C. These are used to identify the deltoid injection site in the upper arm, not the ventral gluteal region.
D. The deltoid is a muscle, and the “femoral bone” (femur) is a long bone of the thigh. These are not the correct landmarks for ventral gluteal injections.

Correct Answer is A
Explanation
Rationale:
A. The humerus is the long bone of the upper arm that extends from the shoulder to the elbow. It articulates proximally with the scapula at the glenoid cavity to form the shoulder joint and distally with the radius and ulna at the elbow joint. It serves as an important site for muscle attachment, allowing for a wide range of arm movements, and also houses the radial nerve and brachial artery along its course.
B. These are a group of eight small bones that form the wrist. They connect the forearm to the hand but are not located in the upper arm.
C. This is one of the two bones of the forearm, located on the lateral (thumb) side. It runs parallel to the ulna and articulates with the humerus at the elbow but is not part of the upper arm itself.
D. This is the second long bone of the forearm, located on the medial (pinky) side. It forms the hinge part of the elbow joint with the humerus, but like the radius, it is not an upper arm bone.
Correct Answer is B
Explanation
Rationale:
A. Adduction refers to moving a limb toward the midline of the body, not straightening a joint.
B. Extension involves straightening a limb at a joint, which increases the angle between the bones, such as straightening the elbow or knee. This movement is essential for proper body mechanics and functional mobility.
C. Abduction involves moving a limb away from the midline of the body and does not increase the joint angle.
D. Flexion is the opposite of extension; it decreases the angle between two bones, such as bending the elbow or knee.
