Final answer:
The requirement for clients with infections that spread via droplet nuclei larger than 5 microns in diameter include face shields.
Step-by-step explanation:
The correct answer is option c) Face shields.
Face shields are a requirement for clients who have infections that spread via droplet nuclei larger than 5 microns in diameter. Face shields provide additional protection to healthcare workers by preventing respiratory droplets from reaching their face and eyes.
For example, rubella, meningococcal pneumonia, and streptococcal pharyngitis are infections that can spread through respiratory droplets. By wearing a face shield, healthcare workers can reduce the risk of infection when caring for these clients.
