A

asthenic

24
Q

for the PA projection as part of the UGI examination why should the lower lungs fields be included on a 14 x 17 IR?

which instructions should be given to the patient if cramping is experienced during filling of the large intestine for a BE?

A

concentrate on deep oral breathing

37
Q

before the enema tip is inserted during a BE, why should a small amount of barium sulfate mixture be allowed to run into a waste basin?

A

to remove air from the tube

38
