DANB's Radiation Health and Safety - Test Reviews Sample Questions

For the patient’s safety, all x-ray units should be surveyed





Correct Answer:
every 4 years or after any changes are made.
sure, let's clarify and expand upon the correct frequency and conditions for surveying x-ray units to ensure patient safety.

x-ray units are critical diagnostic tools in medical settings. they use radiation to create images of the body's internal structures. given their reliance on radiation, there are inherent risks associated with their usage, both to patients and operators. therefore, to minimize these risks, regular surveys and maintenance of these units are essential.

the correct answer to the question is that x-ray units should be surveyed every 4 years or after any changes are made. this recommendation is based on guidelines set forth by various health and safety agencies. regular surveys help ensure that the x-ray units are functioning within the safe radiation exposure limits and that all components are in good working condition.

changes that necessitate a survey of an x-ray unit could include modifications to the x-ray source, alterations in software, hardware upgrades, or any physical impacts that could potentially affect the unit's operation or radiation emission levels. any of these changes could alter the radiation dose a patient receives, which is why a fresh survey is required after any such adjustments.

the surveys are typically conducted by experts who specialize in radiological equipment and radiation safety. these professionals are often affiliated with state health agencies or accredited private organizations that have the authority and expertise to perform such evaluations. their role is to assess the equipment's compliance with safety standards, ensuring that it does not pose any increased risk to patients and staff.

during a survey, the experts will measure radiation levels, inspect the mechanical and electronic components of the x-ray unit, and review operating procedures. they will also check the calibration of the machine to ensure that it is producing the correct amount of radiation as intended.

the emphasis on having these surveys done every four years or following any significant changes is based on the understanding that x-ray technology and safety standards continually evolve. regular updates and checks align with new advancements and regulatory requirements, ensuring ongoing protection for both patients and healthcare providers.

in summary, the frequent and condition-specific surveying of x-ray units is a critical component of maintaining the safety and effectiveness of these diagnostic tools. by adhering to the four-year survey schedule or conducting additional surveys after any significant changes, healthcare facilities help ensure that their x-ray units meet current safety standards and operate safely, thereby protecting patients from unnecessary radiation risks.

A full mouth series of radiographs for an adult is composed of





Correct Answer:
14-16 periapical films and 4 bitewing films.


a full mouth series of radiographs, commonly referred to as a full mouth series (fms) or full mouth survey, is a complete set of dental x-rays used to comprehensively evaluate a patient's oral health. this series is typically used to detect dental problems that are not visible during a regular clinical examination, including issues within the teeth, supporting bone structures, and the areas between the teeth.

for adults, the series generally consists of 14 periapical films and 4 bitewing films. periapical films are used to view the entire tooth structures – from the crown to the root of the teeth that sit in the jaw bone. these films are crucial for detecting dental problems such as impacted teeth, cysts, abscesses, and tumors. each periapical film captures the entire length of a few teeth and provides a detailed view of the periapical bone structure, which helps in diagnosing periodontal disease and assessing the extent of periapical pathology.

on the other hand, bitewing films focus on the crowns of the posterior teeth and are used primarily for detecting interproximal decay (cavities between two teeth) and changes in bone density caused by gum disease. in adults, 4 bitewing films are typically taken – two films for each side of the mouth, one for the upper teeth and one for the lower teeth.

the total of 14 periapical films in a full mouth series covers all the teeth, including the front and back teeth, capturing different angles that might be necessary for comprehensive assessment. the specific teeth included in each film depend on the size of the patient’s mouth and the clinical judgment of the dentist.

this standard setup of 14 periapical films and 4 bitewing films is generally optimal for adults. children, however, typically require fewer films because their mouths are smaller and their teeth fewer. the exact number and type of films for children can vary, influenced by the child's age, size of the mouth, and specific dental health assessment needs.

thus, for an adult undergoing a full mouth series of radiographs, it is crucial to include both periapical and bitewing films as they collectively provide a complete picture of both tooth and bone health, enabling the dentist to make a thorough evaluation and accurate diagnosis. this comprehensive approach is essential for planning appropriate dental treatments and maintaining overall oral health.
