Nursing Assistant Fundamentals
The CNA's Role and Scope
Nursing assistant fundamentals center on knowing what you can do, what you must report, and what you must never do on your own. The CNA provides basic care under the supervision of a licensed nurse: bathing, grooming, dressing, toileting, feeding, repositioning, ambulating, and taking vital signs. Tasks such as assessing a patient, developing a care plan, giving medications, or performing sterile procedures belong to licensed staff. A safe CNA understands the chain of command and reports changes to the charge nurse rather than acting independently.
Core Concepts to Master
- Person-centered care: honor dignity, privacy, autonomy, and cultural and religious preferences.
- Maslow's hierarchy: physiological needs (airway, food, safety) come before comfort or social needs.
- Patient rights: the right to refuse care, to be informed, to privacy, and to be free from abuse and restraint.
- Range of motion and positioning: know the difference between active and passive ROM and the purpose of proper body alignment.
- Observation and reporting: objective findings (a temperature of 101.2 F) versus subjective complaints ("I feel dizzy").
- Abuse, neglect, and mandatory reporting: any suspicion of abuse must be reported immediately per facility policy and law.
Common Traps
Questions often tempt you to "solve" a problem yourself. If a resident refuses a bath, the correct answer is usually to respect the refusal, document it, and notify the nurse, not to force or bargain with the resident. Another trap is confusing subjective and objective data, or choosing a task outside the CNA scope.
Rule of Thumb
When in doubt, do the basic safe thing and report. If a finding is new, worsening, or outside your scope, notify the licensed nurse and document what you observed.
Worked Example
A resident says, "My chest feels tight." The best first action is to stop the task, stay with the resident, and report the complaint to the nurse immediately. Do not tell the resident to rest and check back later, and do not attempt to assess the chest pain yourself.
