ARRT Limited Scope in Radiography (LSPR) Practice Tests & Test Prep by Exam Edge - Features

the american society of radiologic technologists (asrt) is one of the professional societies for the radiologic sciences profession. the organization, established in 1920, has a varied membership of radiologic technologists, educators, students, nuclear medicine and radiation therapy professionals. the asrt goals focuses on advancement in the areas of radiologic technology and imaging, promoting quality standards for education, quality patient care and the well-being, social and economic impact on radiologic technologists. this organization publishes peer-reviewed journals and produces educational material. further, the asrt developed practice standards called "the practice standards for medical imaging and radiation therapy" that focuses on the scope of practice, skills, and conduct for professionals in radiation therapy and medical imaging.

additional, but not all, professional societies focusing on radiologic sciences are the american society of echocardiography, the american health care radiology administrators, the internal society of radiographers and radiologic technologists and the association of educators in imaging and radiologic sciences.

the joint review committee on education in radiologic technology is one of the organizations that accredit radiologic programs, such as radiography, radiation therapy technology, medical dosimetry and magnetic resonance imaging programs. the accreditation of a school means the school complies with educational standards established by accrediting agencies.

the american registry of diagnostic medical sonographers, along with the american registry of radiologic technologists, and nuclear medicine technology certification board and state licensing agencies, best identifies certifying agencies that provides professional certification to individuals who have met the criteria to work in the radiologic field.

the american board of radiology is an organization started in 1934 that certifies radiologists in the areas of diagnostic radiology, therapeutic radiology and radiology. in order to take an examination with the american board of radiology, the individual has to meet certain requirements, such as have a medical degree and residency training.

other organizations for radiologist and physicist are the american college of radiology, the american medical association, the american institute of ultrasound in medicine, the international society for clinical densitometry and the society of nuclear medicine, to name a few.

Correct Answer:

environmental control involves the use of many different approaches to prevent the spread of disease, such as asepsis, handwashing, standard precautions (examples: gloving, personal protective equipment) and transmission based precautions.

the chemical method of infection control changes the environment that the microbe can exist in, which is identified as disinfecting. disinfectants prevent the microbe from growing or thriving in an environment. the types of chemical disinfectants often used in a radiology department are bactericidal agents that kill the microbes.

examples of bactericidal agents are halogens chlorine and iodine. iodine is used mainly as an antiseptic. a chemical disinfectant’s effectiveness is determined by what is being treated (such as the patient or an inanimate object – equipment), the strength of the antiseptic, the type of antiseptic, the types of microbes and the number of microbes and the temperature, for instance.
