Hand hygiene is consistently identified as the most effective measure for preventing healthcare-associated infections.
Question 2: Which type of precaution is used for ALL patient encounters regardless of diagnosis?
- Standard precautions (Correct answer)
- Airborne precautions
- Droplet precautions only
- Contact precautions only
Correct answer: Standard precautions
Standard precautions are applied to all patient care situations as the minimum level of infection prevention.
Question 3: What is the correct order for donning personal protective equipment (PPE)?

- At least daily and after known contamination (Correct answer)
- Once per week
- Only when visibly soiled
- Once per month during deep cleaning
Correct answer: At least daily and after known contamination
High-touch surfaces harbor pathogens and should be cleaned at least daily, with additional cleaning after contamination events.
