A nurse is caring for a client who has an open drain at her surgical site. The nurse knows that an open drain functions in which of the following ways?
A) Pulls fluid by creating a vacuum pressure
B) Drainage occurs passively by gravity and capillary action
C) Pulls fluid by creating a negative pressure
D) Pulls fluid by squeezing the drainage collection chamber
B
Feedback:
Drainage in an open drain occurs passively by gravity and capillary action, which is the movement of a liquid at the point of contact with a solid, which in this case is the gauze dressing. Open drains are flat, flexible tubes that provide a pathway for drainage toward the dressing. Closed drains are more efficient than open drains because they pull fluid by creating a vacuum or negative pressure. This is done by opening the vent on the receptacle, squeezing the drainage collection chamber, and then capping the vent.
