Q

how is infection control done

A
  • use PPEs dependent on patient & setting
  • cassette cleaned & covered with clean cover before & after use
  • dedicated clean & dirty personnel
  • hand hygiene
  • equipment kept on-site for ICU / isolation
  • antiseptic solutions

25
Q

how far should u stand away from patient

A

as far as the coil allows / 2 meters

26
Q

what are concerns for rad safety

A
  • potential complaints from family members
  • space constraints prevent use of high SIDs & maneuvering equipment
  • pregnant staff
27
Q

why should patient not be rotated for AP sitting chest

A

for accurate cardiac assessment

28
Q

AP sitting chest target

A

CR perpendicular to IR @ sternal notch level

29
Q

how should the arms be positioned for AP sitting chest

A

arms rotated medially to bring shoulders forward

30
Q

how long should patient lie on the left side for AP abdomen

A

10 mins to allow free air to rise towards right flank

31
Q

AP abdomen target

A

CR perpendicular to IR, @ level of LCM

32
Q

Left dorsal decubitus abdomen purpose

A

demonstrates free gas & fluid levels

33
Q

Left dorsal decubitus abdomen target

A

CR centered to IR, midway along LCM & include diaphragm

34
Q

AP supine abdomen target

A

CR perpendicular to IR, along MSP, @ iliac crest level

35
Q

AP supine abdomen IR position

A

upper border or IR @ level of axilla & include diaphragm

36
Q

Femur traction IR position

A

IR parallel to femur & include joint nearest to #

37
Q

Femur traction target

A

CR perpendicular to longitudinal axis of femur

38
Q

why is high kVp used in abdomen

A

decrease exposure time & motion unsharpness

39
Q

when is exposure made for abdomen

A

arrested expiration

40
Q

tube used in ETT

A

polyvinyl chloride (PVC) tube

41
Q

Port A catheter common among

A

cancer patients

42
Q

why should AP CXR be done using FRD > 120 cm

A

focus film distance > 120 cm = less magnification & movement unsharpness

43
Q

distention?

A

abdomen swelling due to increased pressure

44
Q

pneumoperitoneum?

A

free gas in peritoneal cavity

45
Q

aortic aneurysm?

A

aortic bulge that passes through belly

46
Q

imperforate anus?

A

anal opening & rectum not developed properly

47
Q

why must IR be horizontal for mobile abdomen

A

avoid grid cutoff which might be mistaken for abdominal mass
