CNA ADLs: Hygiene, Feeding, Elimination, and Comfort
CNA ADLs memory card: bathing and peri-care, dressing weak arm, mouth care, feeding upright, elimination, comfort cues, and clean-to-dirty skills tips.
By MedCertPrep Team · Updated August 5, 2026
This guide is a high-yield memory card for CNA Activities of Daily Living (ADLs): hygiene and dressing, nutrition and hydration, elimination, and rest/sleep/comfort. ADLs are about 22% of scored NNAAP written items (13 of 60) under Physical Care on the 2024 NNAAP Written Content Outline. The same themes drive many personal-care skills: modified bed bath, peri-care, mouth care, feeding, dressing a weak arm, bedpan, and related tasks. Pair it with CNA skills test for checklist rehearsal and Physical Care practice for stems.
Confirm exact skill steps in your Candidate Handbook on Credentia (Find My State) or your Candidate Information Bulletin on Prometric. For NNAAP framing, see NCSBN NNAAP & MACE.

What are ADLs on the CNA exam?
ADLs are the everyday self-care tasks residents need help with. On the NNAAP outline they break into four areas:
| ADL area | Scored items | Weight | High-yield themes |
|---|---|---|---|
| Hygiene, Dressing, and Grooming | part of 13 ADL items | 22% combined | Bath, peri-care, mouth care, dress weak arm, foot care |
| Nutrition and Hydration | included in ADL block | Upright feeding, aspiration cues, fluid offer, diet card | |
| Elimination | included in ADL block | Bedpan, incontinence care, catheter care clean-to-dirty | |
| Rest / Sleep / Comfort | included in ADL block | Positioning, pain report, comfort measures, call light |
ADLs are not "easy points." They fail candidates who rush privacy, reverse clean-to-dirty direction, or force care after a refusal.
What hygiene and dressing rules should you memorize?
Privacy and dignity first
Every personal-care skill starts with explain + privacy. Close the curtain, expose only what you need, and keep the resident covered with a bath blanket or towel when required. Rights language connects directly to CNA resident rights.
Clean to dirty
| Task | Direction / order |
|---|---|
| Face / bed bath | Cleaner areas before peri area |
| Female peri-care | Front to back; clean section of cloth each stroke |
| Catheter care | Clean away from the meatus; hold catheter near meatus without tugging |
| Mouth care | Brush teeth/tongue gently; upright position when listed |
Dressing a weak / affected arm
Common teaching and Credentia-style dressing skills:
- Dress the weak arm first
- Undress the strong arm first
- Support the weak side; do not yank joints
- Offer choice of clothing when the listing/care plan allows
Memory cue: weak first on, strong first off.
Modified bed bath
Many listings cover face and one arm/hand/underarm rather than a full bath. High-yield cues:
- Check water temperature and have the client verify comfort when required
- Wash, rinse, and dry
- Keep the resident covered except the part being washed
- Remove gloves without self-contamination and wash hands
Pro Tip: If two bath answers both sound thorough, pick the one that protects privacy and clean-to-dirty order.

What nutrition and hydration cues are highest yield?
Feeding skills and written stems share the same safety pattern: upright position, correct tray, unhurried pace, and aspiration watch.
Common Credentia-style feeding cues include:
- Explain before feeding
- Check the name card / diet card on the tray before feeding
- Sit the client upright (many listings use about 75 to 90 degrees)
- Keep the signaling device within reach during the meal when required
- Offer fluids between bites as appropriate
- Wipe the mouth and leave the resident clean and upright after feeding
- Wash hands after completing the skill
Written traps:
- Feeding a resident who is flat in bed
- Ignoring choking or wet-sounding cough mid-meal
- Mixing trays / skipping diet-card check
- Forcing bites after refusal
If the resident refuses food, stop forcing, offer alternatives if appropriate, keep them safe, and report. Do not hide the refusal.
What elimination and toileting rules matter most?
Elimination ADLs include bedpan assist, incontinence care, and catheter care.
High-yield checklist cues:
| Skill theme | Safety / infection rules |
|---|---|
| Bedpan | Gloves before placing/removing; lower head of bed before placing/removing when listed; toilet tissue and call signal within reach |
| Incontinence care | Clean promptly; peri-care front to back; dry skin; report skin breakdown |
| Catheter care | Gloves on; clean away from meatus; do not pull the catheter; keep tubing unkinked when moving the resident |
Never place a soiled bedpan on the overbed table or clean linen. Hold soiled linen away from your uniform and do not shake it. Infection-control detail lives in CNA infection control.
What rest, sleep, and comfort actions show up?
Comfort is more than fluff on the exam. Stems test whether you:
- Reposition for pressure relief when assigned
- Report pain instead of ignoring it or inventing medication changes
- Leave the call light within reach
- Keep the bed in a safe low position when required
- Provide warmth, alignment, and privacy during rest
If a resident reports pain, the CNA action is acknowledge, make comfortable within scope, and report to the nurse. Do not decide pain medication on your own.
Which ADL skills should you rehearse for the skills test?
Prioritize these personal-care skills from your official listing:
| Skill family | Why it is high yield |
|---|---|
| Modified bed bath | Privacy + clean-to-dirty + water temperature |
| Peri-care | Front-to-back critical strokes |
| Mouth care / denture care | Upright position + clean technique |
| Feeds client who cannot feed self | Upright + diet card + pace |
| Dresses client with weak arm | Weak first on |
| Bedpan | Glove timing + head-of-bed cues |
| Foot care / catheter care | Skin safety + infection control |
Rehearse openers and closers from CNA skills test: explain, privacy, safety, call light, hand hygiene.

What written traps fail ADL questions?
| Trap | Better action |
|---|---|
| Leave the resident uncovered while gathering supplies | Cover and protect privacy |
| Wipe female peri-care back to front | Front to back, clean cloth section each stroke |
| Dress strong arm first on a weak-arm resident | Dress weak arm first |
| Feed while flat | Raise to upright sitting as required |
| Ignore tray name/diet card | Verify before feeding |
| Finish the bath after clear refusal | Stop, alternative if appropriate, report |
| Place soiled linen on the clean overbed table | Use designated soiled container |
How should you study ADLs this week?
- Memorize the four ADL areas and their privacy/clean-to-dirty rules.
- Drill weak-arm dressing: weak first on, strong first off.
- Drill peri-care front-to-back with clean cloth sections.
- Drill feeding: upright, diet card, unhurried bites.
- Complete focused Physical Care sets in Physical Care.
- Film one bath/peri-care skill and one feeding skill against your official PDF.
- Place ADL blocks on the 4-week study plan.
