Final answer:
The appropriate nursing intervention is to teach that a gown and shoe coverings must be worn in addition to gloves.
Step-by-step explanation:
The appropriate nursing intervention when a student is preparing to enter the room of a client with pulmonary tuberculosis with only gloves on is to teach that a gown and shoe coverings must be worn in addition to gloves (option B).
This is because pulmonary tuberculosis is an airborne disease that can spread through droplets in the air. Wearing gloves alone will not provide sufficient protection against the transmission of the tuberculosis bacteria.
It is important for the student to wear a gown to cover their body and prevent contamination, as well as shoe coverings to avoid carrying the bacteria outside the room.
