A nurse is reviewing the medical history of a client with acute renal failure. Which condition is a risk factor commonly associated with the development of acute renal failure?

A. Correct. A renal ultrasound is an imaging test that uses sound waves to create images of the kidneys. It can help identify kidney stones, obstructions, and other structural abnormalities in the urinary tract.

B. Incorrect. The renal ultrasound does not directly measure the glomerular filtration rate (GFR), which is typically assessed through blood tests.

C. Incorrect. A renal ultrasound does not provide information about the number and types of blood cells in the bloodstream.

D. Incorrect. While a renal ultrasound can visualize the blood vessels in the kidneys, its primary purpose is to assess kidney structure, not blood flow.

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.
