ARDMS (American Registry for Diagnostic Medical Sonography) Practice Test

How often should a sonographer perform quality assurance checks on equipment?

1. Once a year

2. Every shift

3. Regularly, according to facility protocols

4. Only when problems arise

The correct answer is: Regularly, according to facility protocols

Quality assurance checks on ultrasound equipment are crucial to ensure the integrity and reliability of imaging results. Performing these checks regularly, as dictated by facility protocols, allows sonographers to maintain high standards of patient care, minimize errors, and ensure that equipment is functioning optimally. Having a structured approach to quality assurance helps in identifying trends or developing issues before they affect patient outcomes. Facilities often have their own established protocols based on various factors, including the type of equipment, frequency of use, and regulatory requirements. By adhering to these protocols, sonographers ensure consistency and accountability in equipment performance, ultimately supporting accurate diagnoses and effective treatment planning. Options suggesting infrequent checks, such as once a year or only when problems arise, do not support the proactive management approach necessary for optimal ultrasound imaging practices. Similarly, performing checks every shift may not be practical or necessary for all types of equipment, as some may require less frequent assessments based on their usage and the protocols set by the facility. Regular checks, therefore, strike the right balance between diligence and practicality in maintaining imaging standards.
