Why Hand Hygiene Is the First CNA Skill You Must Master
Hand washing is the first skill tested because it:
- Prevents the spread of infections
- Sets the tone for safe resident care
- Demonstrates compliance with state testing requirements
- Shows evaluators that you follow proper CNA procedures
- Establishes professionalism from the start
Every CNA test candidate must perform this skill exactly as written on the state exam checklist. Missing a critical step—especially hand positioning, friction time, or contamination—can result in failure.
Step-by-Step Instructions: CNA Skill 1 — Hand Hygiene (Hand Washing)
Below is a fully rewritten and SEO-optimized version of the CNA hand washing steps, using clear language for WordPress formatting, voice search, and readability.
1. Address the Client and Introduce Yourself
Before approaching the sink or beginning any skill:
- Greet the resident by name
- Introduce yourself using your first and last name
- Explain that you will be washing your hands before providing care
This demonstrates respect, communication, and proper CNA protocol.
2. Turn On the Water
Activate the faucet and adjust the temperature to a comfortable, warm flow.
Avoid touching the inside of the sink, as it is considered contaminated.
3. Wet Hands and Wrists Completely
Place both hands and wrists under the running water, allowing them to become fully wet.
This prepares the skin for effective lathering.
4. Apply Soap to Your Hands
Use enough soap to fully cover:
- Wrists
- Palms
- Backs of hands
- Fingers
- Thumbs
A rich lather is essential for removing microorganisms.
5. Lather for at Least 20 Seconds With Hands Lower Than Elbows
This is one of the critical steps in the CNA hand hygiene skill.
Make sure to:
- Rub all surfaces of your hands and wrists
- Keep fingertips pointed downward
- Maintain hands lower than elbows to prevent contaminated water from running up the arms
- Produce friction for a minimum of 20 seconds
Many students count slowly or sing a 20-second tune to help track time.
6. Clean Fingernails Thoroughly
Scrub your fingertips by rubbing them against the palms of your opposite hand.
This removes trapped bacteria and debris from underneath the nails.
7. Rinse Hands and Wrists With Fingertips Down
Rinse from wrists downward toward fingertips.
Keep your hands lower than your elbows during the entire rinse.
Do not shake your hands or flick water.
8. Dry Hands Completely With a Clean Paper Towel
Using a clean, dry paper towel (or multiple towels):
- Dry the fingertips first
- Continue upward toward hands and wrists
- Avoid rubbing back and forth inside the sink area
- Throw the used paper towel(s) into the waste container immediately
Drying from cleanest to least clean helps prevent recontamination.
9. Use a Clean Paper Towel to Turn Off the Faucet
To avoid touching the faucet with clean hands:
- Use a fresh paper towel to turn off the water
- Dispose of the towel in the waste container
- If the sink uses foot or knee controls, those may be used instead
This is another critical step during the CNA Skills Exam.
10. Avoid Touching the Inside of the Sink
At no point during the skill should your hands, wrists, or fingers touch the inside of the basin. The sink is considered contaminated and contact can result in automatic failure.
Key Points Evaluators Look For During Hand Hygiene
During the CNA Skills Exam, testing evaluators focus on:
- Proper introduction and communication
- Keeping hands lower than elbows during lathering and rinsing
- Washing for a full 20 seconds
- Cleaning underneath fingernails
- Correct drying method
- Using a paper towel to turn off the faucet
- Avoiding any contamination of hands or the sink
Mastering these elements dramatically increases your chances of passing.
Common Mistakes Students Make With the Hand Washing Skill
Avoid the following errors:
- Not washing long enough
- Touching the inside of the sink
- Drying in the wrong order
- Turning off the water with bare hands
- Not keeping fingertips pointed downward
- Forgetting to clean fingernails
- Rushing through the steps
- Not disposing of towels correctly
Practicing slowly and deliberately helps prevent these issues during testing.
Tips for Acing the Hand Hygiene Skill on Your First Try
The hand washing skill sets the tone for your entire exam. Use these tips:
Practice With Real Supplies
Use an actual sink, soap, timer, and paper towels to build muscle memory.
Count Out Loud
Counting your 20 seconds out loud can help with voice search-style learning and keeps you consistent.
Visualize Each Step in Order
Many CNAs rehearse the steps mentally or use mnemonics such as:

Slow Down
The more calm and controlled your actions, the more confident you appear.
