RHS Radiation Safety Practice Test 2025 - Free Radiation Safety Practice Questions and Study Guide

When taking radiographs of a small child who is unable to hold the sensor, the best approach is to ask a parent or guardian to hold the sensor. This choice prioritizes the safety and comfort of the child while ensuring high-quality imaging. A parent or guardian is more likely to be able to hold the sensor steady, thus helping to minimize motion blur and improve the clarity of the radiograph.

Additionally, involving a parent or guardian helps to create a sense of security for the child, which can make the radiographic procedure go more smoothly. It also maintains a safe environment, as the parent or guardian can ensure that the child is in a suitable position during the exposure, and they are typically familiar with the child's behavior and needs.

While positioning and holding the sensor by the assistant could be an option, it may not be practical due to the potential difficulty in maintaining a steady hand, especially if the child is anxious or moving. Rescheduling may not be ideal as it prolongs the child’s need for care, and asking the dentist to hold the sensor is not advisable due to the added complexity and risk of distraction during the procedure.
