Explanation:
,The suction control chamber (Section A) maintains and controls
suction to the chest drainage system; continuous, gentle
bubbling indicates that the suction level is appropriate. The
amount of suction is controlled by the amount of water in the
chamber and not by wall suction. Increasing the amount of wall
suction would cause vigorous bubbling but does not increase
suction to the client as excess suction is drawn out through the vent
of the suction control chamber. Vigorous bubbling would increase
water evaporation and therefore decrease the negative pressure
applied to the system. The nurse should check the water level and
add sterile water, if necessary, to maintain the prescribed level.
, (Option 1) The air leak monitor (Section C) is part of the water
seal chamber. Continuous or intermittent bubbling seen here
indicates the presence of an air leak.
(Option 2) The collection chamber (Section D) is where drainage
from the client will accumulate. The nurse will assess amount and
color of the fluid and record as output.
(Option 4) The water seal chamber contains water, which
prevents air from flowing into the client. Up and down movement of
fluid (tidaling) in Section B would be seen with inspiration and
expiration and indicates normal functioning of the system. This will
gradually reduce in intensity as the lung reexpands.
Educational objective:
The nurse should observe gentle, continuous bubbling in the
suction control chamber. This indicates patency and the
appropriate level of suction being applied to the drainage system.
The nurse is assisting the health care provider (HCP) with a client's
chest tube removal. Just as the HCP prepares to pull the chest
tube, what instructions should the nurse give the client?
1. "Breathe as you normally would." [1%]
2. "Inhale and exhale slowly." [6%]
"Take a breath in, hold it, and bear down." [91%]
