ASRT SEAL EXAM NEWEST 2024 ACTUAL EXAM COMPLETE 170 QUESTIONS AND CORRECT DETAILED
ANSWERS
Identifying with the feelings, thoughts, or experiences of another person. - (answer) Empathy
Under the new standards (NCRP Report No. 91), an effective dose equivalent limit of ____ rem/year for
occupational exposure is recommended. - (answer) The NCRP report states the 5 rem/year is the
acceptable limit for occupational exposure.
Radiation therapy is the first line of treatment for which of the following cancers? - (answer) Radiation
therapy is typically the first line of treatment for head and neck cancers, unless the disease is too
advanced and surgery may be advised. Breast cancer patients typically undergo surgical excision as the
first treatment, and lymphomas and leukemias are generally treated with chemotherapy.
Xerostomia occurs after ______ cGy resulting in significant long-term effects. - (answer) 1,000 cGy
For a member of the general public, the maximum exposure of radiation should not exceed _____? -
(answer) For a member of the general public, maximum exposure should not exceed 100 mrem in one
year's time. For those who work with radiation, the maximum dose limits for adults increases
significantly as follows: 5,000 mrem per year for full body dose, 15,000 mrem per year for lens of the eye
exposure and 50,000 mrem per year for extremities. For an undeclared pregnant radiation worker the
maximum dose exposure remains 5,000 mrem per year but, once declared the maximum dose exposure
drops to 500 mrem over the time period of pregnancy.
In the CT scanner, movable lasers are used to do which of the following? Please select all that apply. -
(answer) Movable lasers are used in the CT simulation room and communicate with virtual simulation
and/or treatment planning systems. While the most common use of these systems is to provide
coordinates for the isocenter of the patient's treatment plan, some systems can project field size, blocks,
and multileaf collimation onto the patient's skin. If moveable lasers are used in the CT simulation,
radiation therapists should complete daily quality assurance on the system.
Halfway through treatment , the radiation therapist notices that the table angle has drifted out of
tolerance by 5 degrees. What should the radiation therapist do? - (answer) Stop the treatment and get
the patient off the table while you notify the doctor
The treatment planning volume which encompasses suspected positive lymph node chains is the: -
(answer) CTV
, ASRT SEAL EXAM NEWEST 2024 ACTUAL EXAM COMPLETE 170 QUESTIONS AND CORRECT DETAILED
ANSWERS
The GTV, or gross target volume, encompasses disease which can be seen on imaging or can be palpated.
The PTV, or planning target volume, includes a margin on the CTV to compensate for set-up
uncertainties. The PTV margin has decreased with the addition of Image-guided radiation therapy (IGRT).
Irradiated volume is anything that receives substantial dose.
Which of the following is an indication to screen patients for lung cancer with low dose CT scans? -
(answer) Low dose CT screening can decrease the mortality of patients who are at high risk for
developing the disease. High risk patients are those between the ages of 55-75 years old, have at least a
30 pack year smoking history, and are current smokers or have quit within the past 15 years.
A formal_________ is a written legally valid document that indicates a patient's decisions about future
medical treatment. - (answer) Advanced directive
This is recognized as a legal document and can be a living will or a durable power of attorney for health
care or other statement signed by the patient.
Prone breast irradiation information: - (answer) Ideal technique for large breasted patients with a left-
sided breast cancer
Stages of grief including denial, anger, bargaining, depression, and acceptance were introduced by: -
(answer) Kubler-Ross
Maslow provided insight for basic needs for all people. Kinsey developed a scale which includes six
parameters or sexual tendencies within the population. Karnofsky is associated with the performance
scale with ranges from 0 to 100%.
MV port film image quality is low due to: - (answer) Increased scatter
Compton scatter is greater with MV beams than kV beams, thereby reducing contrast and image quality.
When interacting with mature adults over the age of 65, radiation therapists should remember: -
(answer) Research shows that most mature adults consider themselves middle aged, are well educated
