Final answer:
In suctioning fluids from a tracheostomy tube, a nurse must limit the suction time to 10 seconds to prevent complications such as hypoxia and trauma to the tracheal lining.
Step-by-step explanation:
When a nurse is suctioning fluids from a male client via a tracheostomy tube, the suctioning time must be limited to ensure the client's safety and to prevent hypoxia. The appropriate suctioning time is 10 seconds. This duration helps to minimize the risk of causing trauma to the tracheal lining or resulting in oxygen deprivation to the client. It is important for the nurse to pre-oxygenate the client before suctioning and to monitor the client closely during the procedure.
