Which of the following bones is called the Collarbone?

Appeared in: Tripura CHO - 2021

Explanation

The clavicle is the anatomical term for the bone commonly known as the collarbone.
It is a slender, S-shaped long bone that lies horizontally at the base of the neck, superior to the first rib.
Functionally, it acts as a strut, connecting the upper limb to the trunk at the sternum (breastbone) and scapula (shoulder blade), allowing for a full range of arm motion.

Option A: The acetabulum is not a bone itself, but rather the socket of the hip joint, located on the pelvic bone.
Option B: The pelvic bone, or hip bone, forms the pelvis. It is a large structure in the lower part of the trunk, not the collarbone.
Option C: The scapula is the anatomical term for the shoulder blade, a large, flat bone on the posterior side of the shoulder.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomy of the Pectoral and Pelvic Girdles as background academic context rather than a clinical decision trigger.
The clavicle is one of the most frequently fractured bones, often from falls on an outstretched hand or direct trauma to the shoulder. Nurses must be able to identify signs of fracture, such as pain, deformity, and swelling.
A key nursing intervention for a suspected clavicle fracture is to immobilize the affected arm in a sling to provide support and reduce pain, followed by a thorough neurovascular assessment of the limb.
What if? A patient with a clavicle fracture reports sudden shortness of breath. This is a medical emergency, as a displaced fracture fragment could potentially puncture the lung (pneumothorax), requiring immediate physician notification and intervention.

How to Approach the Question

This is a factual recall question that tests knowledge of basic anatomical terminology.
First, identify the key term in the question stem, which is 'Collarbone'.
Next, access your memory of anatomical names for common bones in the human body.
Systematically review the options provided: Acetabulum (hip socket), Pelvic (hip bone), Scapula (shoulder blade), and Clavicle.
Match the common name 'Collarbone' with its correct anatomical name, which is 'Clavicle'.
