The Assessment by the Nurse at the Bedside of a Patient

The assessment by the nurse at the bedside of a patient with a chest tube attached to a water seal drainage device would require intervention that would:

A) Ensure no dependent loops in the chest tube.
B) Place the patient in a semi-Fowler position.
C) Change the level of water in the water seal chamber.
D) Increase the level of drainage to 20 ml in 8 hours.
