following denote instrument is used in which of the procedure?

Appeared in: NORCET -4 , 2023

Explanation

The instrument shown is a Joll's Thyroid Retractor, identifiable by its C-shaped frame, central screw lock, and fenestrated blades.
It is a self-retaining retractor, meaning it holds tissues apart without needing to be held by an assistant.
Its specific design is optimized for neck surgery, where it is used to retract the strap muscles and skin to expose the thyroid gland.
Therefore, its primary application is during a thyroidectomy.

Option B: Mastoidectomy is a surgical procedure on the mastoid bone behind the ear.
Option C: Mastectomy is the surgical removal of breast tissue.
Option D: Craniotomy is a surgical operation in which a bone flap is temporarily removed from the skull to access the brain.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification and application of surgical instruments as background academic context rather than a clinical decision trigger.
A circulating or scrub nurse must be able to identify hundreds of surgical instruments to prepare the operating room correctly, anticipate the surgeon's needs, and ensure patient safety.
Using the correct retractor is crucial. In a thyroidectomy, gentle retraction with an instrument like the Joll's retractor helps prevent injury to vital nearby structures, including the recurrent laryngeal nerve (affecting voice) and the parathyroid glands (regulating calcium).
What if? If a retractor with sharp prongs (like a Weitlaner) were used on the neck instead, it could cause significant trauma, bruising, and bleeding to the delicate strap muscles, potentially leading to postoperative pain and swelling.

How to Approach the Question

First, carefully examine the instrument in the image. Note its key features: a C-shaped frame, a screw for self-retention, and two looped blades.
Based on these features, identify the instrument. This is a classic Joll's Thyroid Retractor.
Consider the name of the instrument itself—'Thyroid Retractor'—which is a strong clue to its function.
Review the options provided, which are all surgical procedures.
Match the instrument's name and function to the corresponding procedure. A thyroid retractor is used for a thyroidectomy.
Eliminate the other options by considering the different anatomical locations and the types of retractors that would be required for those surgeries.
