A client is admitted to the hospital with suspected acute renal failure. What initial assessment finding should the nurse anticipate in this client?

A. Incorrect. Increasing the rate of dialysis may further lower the client's blood pressure and worsen the situation.

B. Incorrect. Administering an antihypertensive medication during a hypotensive episode could exacerbate the client's low blood pressure.

C. Correct. The nurse's priority action is to stop the dialysis procedure immediately and notify the healthcare provider of the significant drop in blood pressure. The client may be experiencing a hypotensive episode, which requires prompt evaluation and intervention.

D. Incorrect. Increasing the client's

fluid intake is not appropriate during a hypotensive episode, as it may not rapidly improve blood pressure and could lead to fluid overload.

A. Incorrect. Withholding food and drink for 24 hours is not necessary for a CT scan with contrast dye.

B. Correct. Before a CT scan with contrast dye, it is essential to assess the client for allergies, especially to iodine and shellfish. Contrast dyes used in CT scans contain iodine, and clients with allergies to iodine or shellfish may have an allergic reaction to the contrast dye.

C. Incorrect. While administering intravenous fluids may be beneficial in certain situations, it is not a specific precaution for a CT scan with contrast dye.

D. Incorrect. Removing jewelry and metallic objects is a standard precaution for all imaging procedures, but it is not specific to a CT scan with contrast dye.
