[The amount of receptor exposure is controlled primarily by:] kVp Focal spot size AEC mAs None . [Which of the following is (are) relatively insensitive to radiation?] Nerve tissue Reproductive cells Epithelial tissue Immature sperm cells None . [Older patients should be scheduled:] Late in the day to give them time to build their strength For one examination at a time As early in the day as possible Only when no one else is in the department None . [The law governing patient confidentiality is abbreviated:] CDC HHS ALARA HIPAA None . [Where is the rectifier located in the x-ray circuit?] Between the timer and the step-up transformer Between the step-up transformer and the stepdown transformer Between the primary and secondary coils of the step-up transformer Between the step-up transformer and the x-ray tube None . [The two types of electromagnetic induction are:] Autoinduction and mutual induction Self-induction and mutual induction Generated induction and self-induction Current induction and voltage induction None .

[Critique Figure ] Radiograph is unacceptable; radius and ulna should be superimposed Radiograph is unacceptable; tibia and fibula should be superimposed Radiograph is acceptable, but only one joint is needed Radiograph is acceptable None Comment . [The annual effective dose limit for the general public, assuming frequent exposure, is:] 0.5 mSv 500 mSv 0.05 mSv 1.0 mSv None . [The most common effect from exposure to ionizing radiation is:] Mutations Ionization of atoms in the cells Cell death Nothing None . [Use of the air gap technique:] Works because x-rays are absorbed in the air between the patient and the film Should occur when possible May cause some magnification because of decreased OID Works because scatter radiation travels in divergent paths and misses the IR as a result of increased OID None . [Damage to the cell being irradiated is called:] Genetic Exposed cell Somatic Molecular None .
