Final answer:
The nurse should evaluate the patient's lower extremities for edema.
Step-by-step explanation:
The nurse should evaluate the patient's lower extremities for edema.
Contrast media can be potentially nephrotoxic, meaning it can harm the kidneys. Patients with chronic kidney disease are already at an increased risk for kidney damage. One of the signs of kidney dysfunction is the accumulation of fluid in the body, which can lead to edema, particularly in the lower extremities.
By assessing the patient's lower extremities for edema, the nurse can effectively monitor for any worsening kidney function or potential complications from the use of contrast media.
