For patients with motor disorders and conditions of involuntary movement, which of the following can be adjusted to help avoid blurry images?
a. Increase milliamperage and decrease exposure time.
b. Decrease milliamperage and decrease exposure time.
c. Increase milliamperage and increase exposure time.
d. Decrease milliamperage and increase exposure time.
a. If the possibility of movement during the exposure is identified, the exposure settings—the milliamperage (mA) and the exposure time—may be adjusted to decrease the time required for exposure by increasing the amount of radiation generated. The mA setting controls the amount of radiation generated. By increasing the mA, the x-ray machine will generate more radiation. With this increase in radiation, the exposure time may be decreased.
