When emptying a urinary drainage bag, which step is essential to prevent contamination?

• A. Do not allow the drain tube to touch anything and re-clamp the tube
• B. Wipe the end of the drain tube with an alcohol wipe and replace it in its holder
• C. Pick up the container with one hand and the paper towel with the other, avoiding contact with the floor
• D. Read the amount at eye level on a flat surface

Answer: (A)

Preventing contamination comes from keeping the drainage system closed and free from external contact. The essential step is to ensure the drain tube does not touch anything and to re-clamp the tube after draining. This preserves a sterile pathway and stops pathogens from entering the system or urine from leaking back along the tubing. While wiping the end with an alcohol wipe is good hygiene, it won’t prevent contamination if the tube has touched a non-sterile surface. Reading the amount or handling materials around the bag does not address maintaining a closed, clean system.
