This Infection Control Practice Test Is Built for Real CNA Judgment
Infection control questions aren’t just “wash your hands.” The CNA exam usually tests whether you can spot where germs spread next and what you should do first, next, and last when you’re moving between tasks.
This practice test was built to help you think the way the exam expects: protect the resident, protect yourself, and prevent cross-contamination especially during common moments like removing gloves, handling linens, cleaning surfaces, and reusing shared equipment.

Common Questions We Always Get
nfection control questions are usually about timing and “what to do next.” These FAQs help you spot the safest CNA answer fast.
What infection control topics show up most on the CNA exam?
Hand hygiene timing, gloves/PPE, isolation precautions, cleaning order (clean to dirty), handling linens, and avoiding cross-contamination with shared equipment.
When should I wash my hands instead of using sanitizer?
If hands are visibly dirty, after body fluid exposure, or when the question is clearly about the safest choice. When the exam asks “what should you do next?” handwashing is often the best answer.
If I wear gloves, do I still need hand hygiene?
Yes. Gloves don’t replace hand hygiene. You still need hand hygiene after removing gloves, and before moving to clean tasks or touching clean supplies.
What does “clean to dirty” mean in simple terms?
Start with the cleanest areas first and save the dirtiest for last. This helps prevent spreading germs to cleaner surfaces.
What’s the biggest “trap” in infection control questions?
Touching clean items after a dirty task like adjusting bed linens, touching the call light, or grabbing supplies without hand hygiene.
What’s the safest way to handle soiled linens?
Don’t shake them. Keep them away from your uniform. Hold them from the edges, and place them directly into the proper bag/hamper per facility policy.
What should I do if I get blood or body fluids on me?
Stop and clean it right away. Remove contaminated PPE/clothing safely, wash the area, and report it to the nurse per facility policy.
How do I stop getting tricked by “two correct answers”?
Choose the answer that best matches CNA priorities in this order:
- Prevent spread (hand hygiene / correct PPE)
- Protect resident safety (clean-to-dirty, safe disposal)
- Follow precautions (isolation rules/signage)
- Report exposures or unsafe situations
Can I use this on my phone?
Yes. The quiz works on mobile, tablet, and desktop.
Is the premium trial required?
No. Premium is optional. The free quiz is complete on its own, the premium just unlocks more questions and more sets.
