Final answer:
The client with active tuberculosis (TB) should be placed on droplet precautions.
Step-by-step explanation:
The nursing supervisor should place the client with active tuberculosis (TB) on droplet precautions.
Tuberculosis is often transmitted via airborne transmission when the causative agent, Mycobacterium tuberculosis, is released in small particles with coughs. Patients with tuberculosis must be treated in rooms equipped with special ventilation, and anyone entering the room should wear a mask.
On the other hand, clients with urinary tract infections, C. difficile infection, and viral gastroenteritis would not require droplet precautions.
