Question 1Iodixanol is a —- radiocontrast:AIso-osmolarBLow osmolarCHigh osmolarDNone of the aboveQuestion 1 Explanation:  The osmolality of iodixanol is about 290 milliOsmoles/Kg and it is a dimer. Low osmolar contrasts are non ionic monomers, with osmolality ranging from 700 – 850 mOsm/Kg e.g: Iohexol, Iopamidol. High-osmolar contrast agents with osmolality of 1200 mOsm/Kg or more are no longer used for cardiac catheterization. These were ionic contrasts of the yester years with a lot of associated problems.Question 2Contrast induced renal injury does not involve:AGlomerulusBProximal convoluted tubuleCDescending loop of HenleDAscending loop of HenleQuestion 2 Explanation:  Hence there is no hematuria in contrast induced acute kidney injury.Question 3Predictors of contrast induced acute kidney injury:AEstimated glomerular filtration rate (eGFR)BST elevation myocardial infarction (STEMI)CCardiogenic ...
