QUESTIONS SET A+
✔✔What are major effects of hematopoietic syndrome? - ✔✔Decreased blood cells
infection anemia and hemorrhage
✔✔What is another name for hematopoietic syndrome? - ✔✔Bone marrow syndrome
✔✔Which acute radiation syndrome occurs at a higher dose than hematopoietic
syndrome? - ✔✔Gastrointestinal syndrome
✔✔What system is primarily damaged in gastrointestinal syndrome? -
✔✔Gastrointestinal tract
✔✔What are major manifestations of gastrointestinal syndrome? - ✔✔Severe nausea
vomiting diarrhea dehydration infection and electrolyte imbalance
✔✔Which acute radiation syndrome occurs at the highest dose? - ✔✔Central nervous
system syndrome
✔✔What is another name for central nervous system syndrome? - ✔✔Neurovascular
syndrome
✔✔What are manifestations of central nervous system syndrome? - ✔✔Severe
neurologic and cardiovascular dysfunction confusion loss of coordination seizures coma
and rapid death
✔✔Which acute radiation syndrome has the poorest prognosis? - ✔✔Central nervous
system syndrome
✔✔Which phase of acute radiation syndrome may make the patient appear temporarily
well? - ✔✔Latent phase
,✔✔What organ is especially radiosensitive in children? - ✔✔Developing tissues
throughout the body are more radiosensitive with particular concern for bone marrow
thyroid gonads and developing organs
✔✔Why are pediatric patients more radiosensitive than adults? - ✔✔Their cells divide
more rapidly and they have a longer remaining lifetime for late effects to develop
✔✔What should be done to exposure factors for pediatric patients? - ✔✔Use
appropriately reduced technique while maintaining diagnostic image quality
✔✔Should adult exposure techniques automatically be used for pediatric patients? -
✔✔No
✔✔Why is careful collimation especially important in pediatric imaging? - ✔✔It reduces
irradiated tissue volume scatter and unnecessary dose
✔✔Why should repeat imaging be particularly minimized in children? - ✔✔Children are
more radiosensitive and have longer lifetime risk
✔✔Which developmental period is generally considered most sensitive to radiation
effects? - ✔✔Prenatal development
✔✔What is the major concern with radiation exposure before implantation? -
✔✔Embryonic death or failure to implant at sufficiently high dose
✔✔What is often described as the all or nothing period of prenatal radiation exposure? -
✔✔Preimplantation period
✔✔What is the primary concern during organogenesis? - ✔✔Congenital malformations
and developmental abnormalities at sufficiently high doses
✔✔When does organogenesis occur? - ✔✔Early embryonic development approximately
weeks 2 through 8 after conception
✔✔During which prenatal period is the central nervous system particularly
radiosensitive? - ✔✔Approximately weeks 8 through 15 after conception with sensitivity
extending to a lesser degree later
✔✔What is the principal stochastic concern from prenatal radiation exposure? -
✔✔Increased risk of childhood cancer
✔✔Does pregnancy automatically mean a medically necessary radiographic
examination must be cancelled? - ✔✔No
, ✔✔What should be done when a pregnant patient requires a medically necessary
examination? - ✔✔Optimize the examination to minimize fetal dose while obtaining
necessary diagnostic information
✔✔What should the radiographer do if pregnancy is possible before an examination that
may significantly expose the uterus? - ✔✔Follow facility pregnancy screening policy and
clarify pregnancy status before proceeding when appropriate
✔✔Which examinations deserve particular attention regarding possible pregnancy? -
✔✔Examinations in which the uterus is in or near the primary beam
✔✔Does an x ray examination of an extremity generally expose the fetus as much as
an abdominal or pelvic examination? - ✔✔No
✔✔What is the primary fetal exposure from an examination when the fetus is outside
the primary beam? - ✔✔Scatter radiation
✔✔Should a technologist make independent decisions to cancel medically necessary
imaging solely because a patient is pregnant? - ✔✔No
✔✔What is filtration? - ✔✔Removal of low energy photons from the x ray beam
✔✔Why are low energy photons removed by filtration? - ✔✔They increase patient skin
dose while contributing little to image formation
✔✔What happens to average beam energy when filtration increases? - ✔✔Average
beam energy increases
✔✔What happens to skin dose when appropriate filtration is added? - ✔✔Skin dose
decreases
✔✔What is beam hardening? - ✔✔Increase in average photon energy after lower
energy photons are preferentially removed
✔✔What is inherent filtration? - ✔✔Filtration permanently provided by tube components
such as the glass or metal envelope and window
✔✔What is added filtration? - ✔✔Additional filtering material intentionally placed in the x
ray beam
✔✔What is total filtration? - ✔✔Inherent filtration plus added filtration
