Identify this instrument.

Appeared in: MP CHO -2021 (Shift 1st)

Explanation

The instrument shown is a Dissecting Forceps, characterized by its tweezer-like shape with two arms joined at one end.
This design allows for a spring action, enabling the user to grasp and manipulate tissues by applying pressure with the thumb and fingers.
The tips are typically serrated (as seen in the image) or toothed, designed specifically for holding tissues during surgical procedures.

Option B: A dilator is a solid, rod-shaped instrument used for stretching or widening an orifice or canal, like the cervix. It does not have the grasping function or tweezer-like appearance of the instrument shown.
Option C: A spatula is a flat, paddle-like instrument used for scraping cells (like an Ayre's spatula for Pap smears) or for spreading substances. It is not designed for grasping tissue.
Option D: A blade handle, or scalpel handle, is a solid, flat handle designed to hold a disposable scalpel blade for making incisions. It has a completely different structure and function from the grasping instrument in the image.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of common surgical instruments as background academic context rather than a clinical decision trigger.
The primary clinical relevance is the ability to correctly identify and select the appropriate instrument for a given task to ensure patient safety and procedural efficiency.
Using a toothed dissecting forceps on delicate tissue like the bowel can cause perforation, while using a non-toothed forceps on tough fascia may not provide an adequate grip, leading to slippage and potential injury.
A scrub nurse's ability to anticipate the surgeon's needs and hand them the correct instrument without delay is crucial for maintaining the flow and safety of the operation.

How to Approach the Question

First, carefully examine the image of the instrument. Note its key physical characteristics: its overall shape, the mechanism of action, and the features of its tip.
The instrument is shaped like tweezers, with two arms joined at the back. This indicates a spring-action for grasping.
Observe the tips; they are designed for holding. In this case, they appear to have fine serrations.
Next, evaluate the given options based on your observations.
Option A, 'Dissecting Forceps,' matches the visual evidence of a tweezer-like grasping instrument.
Consider the other options: 'Dilator' (a rod for stretching), 'Spatula' (a flat scraper), and 'Blade handle' (for holding a scalpel). These descriptions do not match the instrument's appearance or implied function.
