The nurse is conducting a staff in-service on renal ultrasounds. Which statement describes this diagnostic test?

  • A. Computed tomography uses external radiation to visualize the renal system.
  • B. Visualization of the renal system is accomplished without exposure to radiation or radioactive isotopes.
  • C. Contrast medium and x-rays allow for visualization of the renal system.
  • D. External radiation for x-ray films is used to visualize the renal system, before, during, and after voiding.
Correct Answer: B

Rationale: Renal ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to produce images of the kidneys and surrounding structures. Unlike computed tomography (CT) scans (Choice A) or intravenous pyelograms (Choice C) which may involve exposure to radiation or contrast medium, renal ultrasounds do not expose the patient to radiation or radioactive isotopes, making it a safe option for imaging the renal system. Ultrasounds are commonly used to assess kidney size, detect kidney stones, evaluate blood flow to the kidneys, and diagnose various renal conditions, such as hydronephrosis or renal cysts.
