Answer to Question 1

Correct Answer: 1, 2, 3, 4
The EGFR is calculated based on the serum creatinine, age, gender, and (in some instances) racial origin. Serum blood urea nitrogen results are not utilized for the EGFR.

Answer to Question 2

Correct Answer: 1
Oral hypoglycemic agents are contraindicated for use with iodinated contrast, as the combination of the two can precipitate renal failure. Patients should be taught to inform all healthcare providers if they have a prescription for an oral hypoglycemic agent. Orange or red-tinted urine, concentrated urine, and urinary catheterizations have no interaction with metformin.
