Answer: C - Nina the New Nurse should know further assessment is required to determine the reason the fluid in the water seal chamber is not moving. Increasing the amount of suction may cause her client harm. Lack of movement of the fluid in the water seal chamber may indicate the lung has re-inflated, or that the tubing is occluded, or that the suction device has malfunctioned. Further assessment is the appropriate nursing action. Adding sterile water to the chamber would be a correct response only if the level in the chamber was not visible. Refilling the chamber as a response to the problem in this scenario is not appropriate.
