module 7 arrt
0.01 Gy - ANS-one rad is equal to _ Gy
0.1-0.4mm lead equivalent - ANS-NCRP recommendations for secondary barriers (lead
thickness)
1 - ANS-pitch that means the table speed matches the rotation speed, so that each
spiral is directly adjacent to the previous and following spirals, fully scanning the
patient's anatomy with no overlaps
1 hour - ANS-contrast reactions can occur up to _ hour after administration
1-4 - ANS-how many hours prior to an exam should oral iodine based or barium be
administered
12-24 hours - ANS-some patients may discard their breastmilk _ hours after contrast
administration
15-20 - ANS-due to dose reduction campaigns, dose was reduced _% from 2006-2016-
while number of scans increased by 20%
2 inches proximal to access site - ANS-where to place tourniquet
2-6 hours - ANS-for Iv contrast, patient should be NPO or clear liquid diet _ hours
before the scan
7 - ANS-NCRP reported that overall medical radiation exposure per person was over _
times greater in 2006 than 1980
70 - ANS-one study suggests that gating can reduce dose by _% without any loss of
diagnostic quality because the beam is only on at times when the most useful data can
be acquired
a broader xray beam subjects more of the patient's anatomy to radiation - ANS-why, in
general, do higher slice scans tend to equate to higher dose?
ability of xray beam to penetrate tissue and controls subject contrast - ANS-two
characteristics of kvp
, absorbed dose - ANS-measures radiation that has been delivered and absorbed by
tissue
an electrocardiogram or a small contrast bolus triggers the scanner to acquire data only
when cardiac function is optimal or when certain arteries are most clear - ANS-how
does gating work?
antihistamines (diphenhydramine) - ANS-medication used to treat allergic reactions
apply pediatric protocols and modify technical factors , and immobilization devices -
ANS-reducing dose with pediatric patients
aspirin - ANS-medication to treat suspected heart attack
asthma, multiple myeloma, pheochromocystoma, certain thyroid diseases, sickle cell
anemia, diabetes, and myasthenia gravis - ANS-contraindications for IV contrast
atropine sulfate - ANS-medication that increases heart rate
avoids excess noise and increased dose compensating for misalignment -
ANS-elements of patient positioning to decrease dose
bedside - ANS-regular piccs can be inserted at _, but power piccs must be inserted with
interventional radiology
blood urea nitrogen, creatinine, or glomerular filtration rate - ANS-three lab values to
evaluate kidney function
cardiac monitor, defibrillator, multifunction pads, resuscitator bag and mask, intubation
supplies, and various emergency medications - ANS-six pieces of equipment on a crash
cart
chest scan - ANS-most common exam ordered on pregnant patients
children are at higher risk for radiation-induced illnesses and have more time to
accumulate lifetime radiation dose - ANS-two reasons radiation protection is of greater
importance for children
