| The principle advantage of a low osmolality non-ionic contrast agent is its decreased | Toxicity. |
| A patient is to be scheduled for a BE, IVU, and a GI Series. The sequence for these exams is | IVP, BE, GI. |
| As the concentration of an iodine contrast media is increased, an increase in ______ should be anticipated. | Viscosity, Toxicity and Opacity. |
| There are two general classifications for getting materials into the blood stream | Enteral administrations (the absorption of medications through the mucus membranes) Parenteral administrations are those that involve the placement of the agent into the tissues or into the blood stream (injections). |
| A patient is to be scheduled for a GI series, gallbladder, and an L-spine. What is the proper sequence? | L-spine, gallbladder, GI Series. |
| Because of the possibility of residual contrast media, which of the following studies is normally performed last in a sequence of exams? Esophogram, BE, IVP, Gallbladder series? | Esophogram. |
| The esophogram is performed last in a series because it may take up to? | 2 days for the barium to be completely eliminated from the GI tract. |
| A 4 year old is brought down to the radiology department for an intravenous urogram. The radiologist orders 40% of the normal 50 cc adult dosage be used. The amount to be prepared is? | 20 cc (multiply the adult dose by 40%) |
| A barium enema is to be performed on a patient suspected of having a perforated bowel. The contrast media preferred for this procedure would be a | Water based iodine preparation. |
