Overview
Personal care skills are a core component of the CNA role, encompassing bathing, oral hygiene, grooming, dressing, skin care, and patient communication. These skills ensure patient comfort, prevent infection and skin breakdown, and uphold patient dignity and rights. Mastery of the correct techniques, sequences, and safety precautions is essential for both the exam and clinical practice.

Bathing
Key Concepts
Bathing maintains hygiene, prevents infection, and gives the CNA an opportunity to assess the patient's skin condition. The guiding principle is always clean to dirty to prevent cross-contamination.
Wash Order for a Complete Bed Bath
1. Face
2. Arms
3. Chest
4. Abdomen
5. Legs
6. Back
7. Perineal area (last)
> Always change the water before washing the perineal area.
Water Temperature
• 105°F–110°F (40.5°C–43.3°C)
• Always test the water temperature before applying it to the patient
• Confirm comfort with the patient
Perineal Care
• Female patients: Always wipe front to back (urethra → anus) to prevent urinary tract infections
• Perform perineal care after every bedpan use to prevent infection, skin breakdown, and odor
• Change water before beginning perineal care
Back Rub
• Use long, firm, upward strokes along the spine
• Use circular motions over bony prominences
• Keep hands in continuous contact with skin throughout
• If redness or a skin break is found → stop immediately, report and document to the nurse
Key Terms
• Cross-contamination – Transfer of microorganisms from a dirty area to a clean area
• Perineal care (peri-care) – Cleaning of the genital and rectal area
• Bony prominences – Areas where bone is close to the skin surface (heels, hips, sacrum, elbows)
⚠️ Watch Out For
• Never massage directly over reddened skin during a back rub — report it instead
• Forgetting to change bath water before perineal care is a common error
• Always check water temperature with your wrist or thermometer, never assume it is safe

Oral Hygiene
Key Concepts
Oral hygiene prevents infection, aspiration pneumonia, and mucosal drying. Frequency and patient positioning are critical safety factors, especially for unconscious patients.
Unconscious Patients
• Position in lateral (side-lying) position with head turned to the side to prevent aspiration
• Provide mouth care at least every 2 hours
• Use minimal fluid and suction equipment if available
• Use swabs (Toothettes) rather than a toothbrush
Denture Care
| Step | Action |
|------|--------|
| Hold dentures over | A basin lined with a washcloth or filled with water to cushion a drop |
| Clean with | Denture cleanser and a denture brush on all surfaces |
| Rinse | Thoroughly with cool water before returning to patient |
| Store overnight | In a labeled denture cup with cool water or denture-soaking solution |
> Never use hot water on dentures — it causes warping.
What to Observe and Report
• Redness, swelling, sores, or bleeding
• White patches (possible thrush/fungal infection)
• Unusual odor
• Loose teeth
Key Terms
• Aspiration – Inhalation of fluid or debris into the lungs
• Mucous membranes – Moist lining of the mouth and airways
• Denture cup – Labeled container used for denture storage
⚠️ Watch Out For
• Never leave an unconscious patient in a supine (flat on back) position during oral care — aspiration risk
• Always label the denture cup with the patient's name
• Forgetting to line the basin when handling dentures risks breakage

Grooming & Hair Care
Hair Care
• For long, tangled hair: Start at the ends and work up toward the scalp in small sections
• Hold hair above each section being combed to reduce pulling and pain
Shaving
| Safety Razor | Electric Razor |
|-------------|----------------|
| Apply warm, moist towel or shaving cream first | Preferred for patients on anticoagulants |
| Check for bleeding precautions before use | Reduces risk of cuts and uncontrolled bleeding |
| Obtain nurse approval if needed | Safer for most residents |
Nail Care
| Patient Type | CNA Action |
|-------------|-----------|
| Diabetic patient | Do NOT trim nails — refer to nurse or licensed professional |
| All other patients | Observe and report redness, swelling, ingrown nails, infection signs |
Why diabetics require special nail care:
• Poor circulation = delayed healing
• Even a small cut can lead to serious infection or ulceration
Key Terms
• Anticoagulant – A medication that slows blood clotting (e.g., warfarin, heparin)
• Ingrown nail – A nail that grows into the surrounding skin, causing pain or infection
• Bleeding precautions – Orders limiting activities that could cause bleeding
⚠️ Watch Out For
• Never trim the nails of a diabetic — this is a scope-of-practice boundary on the exam
• Always check medications and care plan before shaving with a safety razor
• Never start combing hair from the scalp down on a tangled patient — it causes pain and breakage

Dressing & Undressing
The Golden Rule: "Weak First, Strong First" Framework
| Task | Which Side First? | Why? |
|------|------------------|------|
| Dressing | Weak/injured side FIRST | Limited range of motion; easier to pass garment over affected limb |
| Undressing | Strong/unaffected side FIRST | Removes the garment from the good side before sliding off the weak side |
> Memory tip: "Dress the worst, undress the best."
IV Line Management During Dressing
1. Thread the IV tubing and bag through the sleeve first
2. Then place the arm through the sleeve
3. Ensure the IV line remains patent (open) and unkinked throughout
Patient Rights During Dressing
• Always respect the patient's right to choose their own clothing
• Offer options, but allow the patient to make the final decision
• This upholds dignity and autonomy
Key Terms
• Affected side – The weak, injured, or paralyzed side of the body
• Unaffected side – The stronger, healthy side of the body
• Patent – Open and unobstructed (referring to IV lines or airways)
• Autonomy – The patient's right to make decisions about their own care
⚠️ Watch Out For
• This is a frequently tested topic — memorize the dressing/undressing sequence
• Never force a garment over a painful or stiff joint — reposition to ease movement
• IV management during dressing is a common exam scenario

Skin & Pressure Injury Prevention
Four Contributing Factors to Pressure Injuries
| Factor | Description |
|--------|-------------|
| Pressure | Sustained force compressing tissue over a bony prominence |
| Friction | Rubbing of skin against a surface (e.g., bed sheets) |
| Shear | Skin layers moving in opposite directions (e.g., sliding down in bed) |
| Moisture | Prolonged contact with urine, stool, or sweat weakens skin integrity |
Pressure Injury Stages (Exam Focus)
| Stage | Appearance |
|-------|-----------|
| Stage 1 | Intact skin with non-blanchable redness (does not fade when pressed) |
| Stage 2 | Partial thickness skin loss; may look like a blister or shallow open wound |
| Stage 3 | Full thickness skin loss; subcutaneous tissue visible |
| Stage 4 | Full thickness with exposed bone, tendon, or muscle |
Repositioning
• Reposition bedridden patients at least every 2 hours
• This relieves pressure on bony prominences and restores circulation
• Document repositioning per facility policy
Critical Rule: Do NOT Massage Reddened Areas
• Massaging over redness can disrupt fragile capillaries and worsen ischemia
• Instead: report and document the finding immediately
Incontinence Skin Care
1. Cleanse skin promptly after each incontinence episode
2. Dry thoroughly
3. Apply a moisture barrier cream or ointment to protect skin
Key Terms
• Non-blanchable redness – Redness that remains when pressure is applied; sign of Stage 1 pressure injury
• Ischemia – Inadequate blood supply to tissue
• Moisture barrier – A cream or ointment that protects skin from prolonged moisture exposure
• Bony prominence – An area where bone is near the skin surface and at high risk for pressure injury
⚠️ Watch Out For
• Never massage reddened bony prominences — this is a direct exam trap
• Non-blanchable redness = Stage 1 pressure injury — know this definition
• Repositioning every 2 hours is the standard; memorize this number

Patient Rights & Communication During Personal Care
Before Every Personal Care Procedure
The CNA must always:
1. Explain the procedure to the patient
2. Obtain consent (verbal agreement)
3. Provide privacy (close curtains, door)
4. Ensure comfort throughout the procedure
Handling Refusal of Care
If a patient refuses personal care (e.g., a bath):
| Step | Action |
|------|--------|
| 1 | Respect the refusal — do not force the care |
| 2 | Report the refusal to the nurse |
| 3 | Document the refusal per facility policy |
| 4 | Offer alternatives (e.g., partial bath, different time) |
> Forcing care on a patient who has refused is a violation of patient rights and may constitute abuse.
Key Terms
• Informed consent – The patient's right to understand and agree to any procedure before it begins
• Patient autonomy – The right to make decisions about one's own body and care
• Dignity – Treating patients with respect and preserving their sense of worth
• Refusal of care – A patient's legal right to decline any treatment or personal care
⚠️ Watch Out For
• Never force personal care — always respect the refusal and report it
• Skipping explanation or consent before a procedure violates patient rights, even for simple tasks
• Always provide privacy — failing to close curtains is a dignity violation
