Measures and Records Urinary Output

Read the volume markings on the urinary drainage bag while the bag stays HUNG ON THE BED FRAME below the level of the bladder (gravity drainage prevents backflow and infection). Or empty the bag into a graduated cylinder for precise measurement. Record volume in mL.

Why this matters

Bag stays below the bladder. Read at eye level. Empty, rinse, record.

Quick tips

  • Gloves go on before you touch the bedpan.
  • Read the volume at eye level on a flat surface.
  • If the level is between lines, round up to the nearest 25 mL.

Common mistakes

  • Handling the bedpan before putting on gloves, which exposes you to the urine and you will not get credit for fixing it after a reminder.
  • Reading the container from above or while holding it, so the amount is off by more than 25 mL.
  • Spilling or splashing during the pour.
  • Recording while still gloved or before washing hands.
