The nurse is caring for a client with an elevated serum blood urea nitrogen (BUN) and creatinine. The client is scheduled for a CT scan with contrast. The nurse would:
1. Notify the health care provider to withhold contrast.
2. Monitor blood pressure before and after the procedure.
3. Hydrate well prior to the procedure.
4. Keep the client NPO after the procedure.
Notify the health care provider to withhold contrast.
Rationale: The nurse should notify the health care provider to withhold contrast because a client with an elevated BUN and creatinine indicates impaired renal function. With an impaired renal function, the client would not be able to readily excrete the contrast media. This may lead to an intrarenal cause of acute renal failure. Blood pressure would not be influenced by the administration of the contrast media. With the renal impairment of the client, hydration would not decrease the risk of the client developing acute renal failure.
