- Benefit: Promotes skin health and reduces fall risk.
6. Positioning & Repositioning
- Skill: Turn and position patients every two hours (or as ordered) to prevent pressure ulcers.
- Technique: Use the “log roll” method for spinal precautions.
7. Mobility Assistance
- Skill: Assist with ambulation, transfers, and use of assistive devices (walkers, canes, wheelchairs).
- Safety tip: Always have a “spotter” when moving high‑risk patients.
8. Activities of Daily Living (ADLs) – Bathing
- Skill: Provide bedside, tub, or shower bathing while preserving modesty and skin integrity.
- Focus: Use warm water (37‑38 °C) and gentle, fragrance‑free cleansers.
9. ADLs – Grooming & Oral Hygiene
- Skill: Brush teeth, clean dentures, comb hair, and trim nails, adapting techniques for cognitive or physical limitations.
10. ADLs – Toileting & Incontinence Care
- Skill: Assist with voiding, catheter care, and use of absorbent products; perform perineal hygiene with a “front‑to‑back” approach.
11. ADLs – Feeding & Nutrition
- Skill: Offer meals, assist with eating, monitor intake, and recognize signs of dysphagia.
- Note: Document any refusal or difficulty to alert the dietitian.
12. Skin Care & Pressure Ulcer Prevention
- Skill: Inspect skin daily, apply barrier creams, and document any redness or breakdown.
13. Wound Care (Basic)
- Skill: Change simple dressings, apply antiseptic, and report signs of infection.
- Limitation: CNAs do not perform deep debridement; they follow RN orders.
14. Catheter & Drain Care
- Skill: Maintain clean technique for urinary catheters, drainage tubes, and ostomy sites.
15. Medication Assistance (Non‑IV)
- Skill: Verify patient identity, administer oral medications, and record accurately.
- Caution: CNAs never dispense medication; they only assist under RN supervision.
16. Vital Signs Trend Analysis
- Skill: Recognize abnormal trends (e.g., rising temperature, dropping blood pressure) and report promptly.
17. Emergency Response & CPR
- Skill: Perform basic life support (BLS) including chest compressions, rescue breaths, and use of an automated external defibrillator (AED).
18. Documentation & Charting
- Skill: Write clear, concise, and objective notes in the electronic health record (EHR) or paper chart.
19. Communication & Interpersonal Skills
- Skill: Use therapeutic communication, active listening, and cultural sensitivity when interacting with patients and families.
20. Team Collaboration
- Skill: Relay information during shift hand‑offs, respond to nurse requests, and participate in care planning meetings.
21. Safety & Fall Prevention
- Skill: Identify fall hazards, use bed alarms, and educate patients on safe ambulation.
22. Privacy & Confidentiality (HIPAA)
- Skill: Protect patient information, discuss care only with authorized personnel, and secure records.
23. Professionalism & Ethical Practice
- Skill: Demonstrate punctuality, accountability, and respect for patient rights; adhere to the CNA Code of Ethics.
How to Master the 23 CNA Skills
1. Structured Classroom Learning
- Attend a state‑approved CNA program that includes both lecture and hands‑on labs.
- Use simulation mannequins to practice vital signs, catheter care, and CPR repeatedly.
2. Clinical Rotations
- Request to observe and assist in varied units—medical‑surgical, geriatrics, and rehab—to see how each skill adapts to different patient populations.
3. Repetition & Muscle Memory
- Perform each skill daily during training; the more you repeat, the less you’ll have to think about the steps, freeing mental bandwidth for patient interaction.
4. Peer Teaching
- Explaining a skill to a fellow student reinforces your own understanding and highlights gaps you may have missed.
5. Use Checklists
- Keep a pocket‑size checklist of the 23 skills. Before each shift, review the list and note any areas needing extra focus.
6. Seek Feedback
- Ask supervising nurses to evaluate your technique on hand hygiene, body mechanics, and documentation. Constructive criticism accelerates improvement.
7. Continuous Education
- Attend workshops on wound care updates, new infection‑control protocols, or advanced CPR refreshers to stay current.
Scientific Explanation Behind Key Skills
Hand Hygiene & Infection Control
Research shows that proper handwashing removes up to 99 % of transient microorganisms. The CDC’s 5‑step technique (wet, lather, scrub 20 seconds, rinse, dry) creates a mechanical shear that dislodges pathogens, while alcohol‑based rubs disrupt lipid membranes of viruses and bacteria.
Pressure Ulcer Prevention
Pressure ulcers develop when capillary blood flow is occluded for more than 2 hours. Repositioning every 2 hours restores perfusion, while moisture‑wicking linens reduce shear forces. The “Braden Scale” quantifies risk; CNAs who regularly assess and act on the scale see a 30 % reduction in ulcer incidence.
Most guides skip this. Don't.
CPR Effectiveness
High‑quality chest compressions—depth of 2‑2.Now, 4 in, rate of 100‑120/min, and full recoil—maintain coronary perfusion pressure above 20 mm Hg, the threshold for return of spontaneous circulation (ROSC). Early defibrillation within the first 3‑5 minutes dramatically improves survival odds.
