Lead rubber aprons are used in OT when following equipment is used?

Appeared in: BCCL kharkhanda Staff Nurse - 2015

Explanation

Image intensifiers are integral parts of fluoroscopy and C-arm machines, which utilize X-rays to generate real-time intraoperative images.
X-rays are a form of ionizing radiation, which can damage living tissue and increase cancer risk with cumulative exposure.
Lead aprons are essential personal protective equipment (PPE) that effectively block X-rays, shielding the torso and vital organs of healthcare personnel from radiation.
Therefore, their use is mandatory whenever an image intensifier or any other X-ray-emitting device is active in the operating theatre.

Option A: Electric cautery uses high-frequency electrical current to generate heat for cutting and coagulation. It does not produce ionizing radiation.
Option B: A ventilator is a mechanical life-support device that moves breathable air into and out of the lungs. It does not involve any form of radiation.
Option D: A pulse oximeter is a non-invasive monitoring device that uses light waves (spectrophotometry) to measure the oxygen saturation of the blood. It does not emit ionizing radiation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Radiation safety and Personal Protective Equipment (PPE) in the operating theatre as background academic context rather than a clinical decision trigger.
Adherence to the ALARA (As Low As Reasonably Achievable) principle is a cornerstone of radiation safety, guiding practices to minimize exposure for both patients and staff.
Personnel who are regularly involved in procedures using fluoroscopy must wear a dosimeter badge to track their cumulative occupational radiation exposure over time.
Lead aprons protect radiosensitive organs like the gonads, bone marrow, and thyroid (with a thyroid shield), reducing the long-term risks associated with radiation.

How to Approach the Question

First, identify the key subject of the question, which is 'Lead rubber aprons'.
Recall the primary purpose of lead aprons: to provide protection against ionizing radiation, specifically X-rays.
Next, systematically evaluate each of the four equipment options based on its fundamental principle of operation.
Ask yourself for each option: 'Does this device produce or use X-rays?'
Eliminate the options that do not use ionizing radiation: Electric cautery (electricity/heat), Ventilator (air pressure), and Pulse oximeter (light).
Identify that the 'Image intensifier' is a core part of an X-ray imaging system (C-arm/fluoroscopy).
