An undesirable characteristic of ionic contrast agents is their

B)neutral osmolality.
C)neutral pH.
D)dissociation into a cation and an anion when dissolved in plasma.

Question

Quizplus · Accepted Answer

Efforts to decrease the many side effects of ionic iodine contrast media resulted in the development of molecules that do not dissociate into anions and cations.The chemical breakdown into an anion and cation can be an irritant to cells.Although both ionic and nonionic iodine media have physiologic effects on the body,most ionic agents are higher osmolality contrast media and therefore have shown greater effects and adverse reactions.
