A surgical mask should be changed?

After every patient
Once a day
Every 4 hours
Only if visibly soiled

The correct answer is: After every patient

It is important to change surgical masks frequently to maintain their effectiveness. Option B and C are not as frequent as option A and may not provide adequate protection. Option D may not be sufficient as microscopic particles may still accumulate on the mask even if it is not visibly soiled. Therefore, after every patient is recommended to reduce the risk of contamination and ensure maximum protection.
