Questions and Answers

What is the purpose of chemolysis in treating kidney and urinary stones?

  • To dissolve the stone using chemical solutions (correct)
  • To remove the stone through a surgical incision
  • To physically break down the stone with shock waves
  • To disintegrate the stone with laser technology

Why is increased fluid intake encouraged in patients with renal calculi?

  • To promote dehydration and stone formation
  • To increase hydrostatic pressure in the urinary tract (correct)
  • To prevent the passage of the stone through the urinary tract
  • To decrease hydrostatic pressure in the urinary tract

What is a nursing intervention for patients with renal calculi experiencing severe acute pain?

  • Providing opioid analgesic agents (correct)
  • Monitoring for changes in blood pressure
  • Encouraging bed rest
  • Administering antipyretic agents
