RADIOGRAPHY ESSENTIALS SIMULATED EXAM 2024 WITH 100% CORRECT ANSWERS

What is the link between radiation dose and genetic effects?Answer - The link has been demonstrated in human studies and animal studies and increased risk to humans cannot be predicted with respect to an individual. What changes and kilovoltage will result in the greater reduction of patient dose, when milliampere- seconds is adjusted to compensate for the change?Answer - Increase KVP by 30%. What kind of image receptor system speeds will result in the lowest patient dose?Answer - Faster speed image receptor system. What is the primary purpose of using gonad shields during radiography?Answer - Reduce the likelihood of genetic effects. What are the two types of gonad shields?Answer - Contact and shadow. When should gonad shielding be used?Answer - When the gonads are within 5 cm of the radiation field. The greatest cause of unnecessary radiation to patients that can be controlled by the limited operator is?Answer - Repeat exposures. The limited operator can reduce repeat exposures by?Answer - Clearly instructing patients. How does x-ray beam restriction minimize patient exposure?Answer - It limits the radiation field to the area of interest.
