Which term describes the insertion of a sterile tube into the urinary bladder?

• A. Nocturia
• B. Oliguria
• C. Polyuria
• D. Urinary Catheterization

Answer: (D)

Urinary catheterization is the insertion of a sterile tube into the urinary bladder. This procedure uses sterile technique to place a catheter through the urethra into the bladder to drain urine, relieve urinary retention, obtain a sterile urine sample, or monitor urine output in a patient. The other terms describe urine output or timing rather than a procedure: nocturia means waking at night to urinate, oliguria means producing a smaller than normal amount of urine, and polyuria means producing an abnormally large amount of urine.
