When a patient is scheduled for a CT scan with dye, it is important for the healthcare provider to assess the patient's kidney function. The contrast dye used in the CT scan can be harmful to the kidneys, particularly in patients with existing kidney problems. Creatinine and glomerular filtration rate are measures of kidney function, so it is important to assess these values before administering contrast dye. An allergy history is also important to assess, but it is not the most important assessment in this situation. The other options are not directly related to the administration of contrast dye.
