Appeared in: AIIMS Delhi NO - 2018

Explanation

The image shows a monopolar electrocautery pencil, characterized by its pen-like shape, a single active electrode at the tip, and control buttons on the handle.
This instrument functions by delivering high-frequency electrical current from a generator to the surgical site for cutting or coagulation of tissue.
The term 'monopolar' indicates that the electrical circuit is completed by a current that flows from the instrument's tip, through the patient's body, to a separate return electrode (grounding pad) placed on the patient's skin.

Option B: The electrical wire is only a component of the electrocautery device; it is not the entire instrument shown.
Option C: A USG (ultrasound) probe has a distinctly different appearance, typically with a larger, smooth transducer head used for imaging, and it does not have an electrode tip for cutting or coagulation.
Option D: 'Electrical IV Set' is not a standard medical term. IV sets are used for administering intravenous fluids and have a completely different structure, consisting of tubing, a drip chamber, and a connector for a cannula.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of surgical instruments, specifically electrocautery devices as background academic context rather than a clinical decision trigger.
A primary nursing responsibility during surgeries using monopolar cautery is ensuring patient safety by correctly applying the grounding pad. It must be placed on a clean, dry, well-vascularized muscle mass, avoiding bony prominences, scar tissue, and areas with metal implants.
Nurses must inspect the patient's skin integrity at the grounding pad site before application and after removal to check for any signs of burns or irritation.
What if? If the electrosurgical unit's alarm for the grounding pad sounds during a procedure, it indicates a fault in the circuit. The nurse must immediately notify the surgeon, and the procedure should be paused until the pad's connection and adherence are checked and corrected to prevent patient injury.

How to Approach the Question

First, carefully observe the visual characteristics of the instrument in the image. Note its overall shape (pen-like), key components (buttons, a metal tip, an attached wire), and size.
Next, consider the likely function of an instrument with these features in a medical or surgical context. A sharp tip with electrical connections suggests a function involving cutting or heating tissue.
Evaluate each of the given options against your visual analysis. 'Monopolar Electrocautery' describes a device that matches the appearance and inferred function.
Eliminate the distractors. 'Electrical wire' is only a part of the device. 'USG probe' has a different shape and is used for imaging. 'Electrical IV Set' is an incorrect term for a different type of equipment.
Conclude by selecting the option that accurately and completely identifies the instrument shown.
