Louisiana CNA key terms

Louisiana CNA · Get comfortable with the vocabulary.

Vital signs

Body temperature, pulse, respiration, and blood pressure, often called TPR and BP. They show how well the body is working, so aides measure and record them accurately and report values outside the resident's usual range.

Related: Blood pressure, Radial pulse, Respiration
Blood pressure

The force of blood pushing against artery walls, recorded as two numbers such as 120/80, systolic over diastolic. The aide measures it with a cuff and gauge while the resident sits or lies quietly.

Related: Vital signs, Radial pulse
Radial pulse

The heartbeat counted at the wrist on the thumb side of the forearm. It is felt with two fingers for a full minute, noting rate, rhythm, and strength, and reported when it is irregular or unusually fast or slow.

Related: Vital signs, Blood pressure
Respiration

One full breath in and one full breath out. The aide counts breaths for a full minute without telling the resident, noting the rate, depth, rhythm, and any abnormal sounds such as wheezing.

Related: Vital signs
Intake and output (I&O)

A record of all fluids a resident drinks and all fluids lost as urine, vomit, wound drainage, or liquid stool. Amounts are measured in milliliters and totaled each shift so the nurse can judge fluid balance.

Related: Vital signs
Range of motion (ROM)

Moving a joint through its full normal movement, either by the resident alone (active) or with the aide's help (passive). Regular range of motion keeps joints flexible and helps prevent contractures and stiffness.

Related: Contracture, Repositioning
Contracture

A fixed shortening of muscles and tendons that locks a joint in a bent position and cannot be reversed. It develops when a limb is not moved or positioned correctly, so range of motion and good positioning matter.

Related: Range of motion (ROM), Repositioning
Pressure injury

Damage to skin and deeper tissue, usually over a bony area such as the tailbone, hip, or heel, from pressure that cuts off blood flow. Also called a bedsore or decubitus ulcer.

Related: Repositioning
Repositioning

Changing a resident's body position on a set schedule, usually at least every two hours, to relieve pressure on the skin and keep blood circulating. Each turn and the position used should be written down.

Related: Pressure injury, Contracture
Gait belt

A wide strap buckled around a resident's waist that gives the aide a firm, safe hold during walking and transfers. It is never used to lift the resident and is removed after the move.

Related: Range of motion (ROM)
Aspiration

Breathing food, liquid, saliva, or vomit into the airway instead of swallowing it. It can cause choking or pneumonia, so residents with swallowing problems are fed slowly and kept upright.

Related: Dysphagia, NPO
Dysphagia

Difficulty swallowing. Warning signs include coughing or choking during meals, a gurgly voice, drooling, and food staying in the cheek; the aide reports these and follows the ordered diet texture and liquid thickness.

Related: Aspiration, NPO
NPO

An order meaning nothing by mouth, including food, water, ice chips, and oral medicines. The aide removes the water pitcher, reminds the resident, and tells the nurse if the resident eats or drinks anyway.

Related: Aspiration, Dysphagia
Hand hygiene

Cleaning the hands with soap and water or an alcohol-based rub. It is the most effective way to stop the spread of infection and is done before and after every contact with a resident.

Related: Standard precautions
Standard precautions

Infection-control steps used with every resident because any blood or body fluid may carry germs. They include hand hygiene, gloves, gowns, masks, and careful handling of soiled linen and sharps.

Related: Hand hygiene
Perineal care

Washing the genital and anal area, wiping from front to back and using a clean area of cloth for each stroke. It is done during bathing and after incontinence to prevent infection and skin breakdown.

Related: Hand hygiene
Resident rights

The legal freedoms nursing home residents keep, such as privacy, dignity, choice, visitors, personal belongings, and freedom from abuse. Aides protect these rights and report any violation they see.

Related: Dignity, Ombudsman
Dignity

Treating each resident as a worthwhile person by knocking first, covering them during care, offering choices, and speaking respectfully. It protects self-worth when a resident needs help with intimate tasks.

Related: Resident rights, Empathy
Empathy

Recognizing and sharing another person's feelings so they know they are understood. Unlike pity, empathy does not look down on the resident but stands alongside them in their situation.

Related: Active listening, Therapeutic communication
Active listening

Giving full attention to a resident's words and feelings through eye contact, nods, and repeating back what was heard. It invites the resident to talk and shows their concerns are taken seriously.

Related: Empathy, Therapeutic communication

Purposeful, respectful conversation that helps a resident express feelings and understand their care. It uses open questions, silence, and honesty rather than arguing, judging, or making false promises.

Related: Active listening, Empathy
Reality orientation

Calmly reminding a confused resident of who they are, where they are, and the date or time using clear, repeated cues. It helps most with new or short-term confusion rather than advanced dementia.

Related: Delirium, Dementia
Dementia

A group of brain disorders that gradually damage memory, thinking, judgment, and the ability to do daily activities. It is not a normal part of aging, and care focuses on routine, safety, and patience.

Related: Sundowning, Reality orientation
Delirium

Sudden confusion that develops quickly, often caused by infection, medicines, pain, or dehydration. It can often be reversed with treatment, so any new confusion must be reported to the nurse at once.

Related: Dementia, Reality orientation
Sundowning

Restlessness, confusion, or agitation in a person with dementia that begins in late afternoon or evening. Calm routines, soft lighting, quiet activities, and less daytime napping often reduce it.

Related: Dementia, Delirium
Abuse

Deliberately harming a resident, whether by hitting, yelling, mocking, forcing care, or misusing their money. Aides must report suspected abuse immediately and are legally protected for reporting in good faith.

Related: Neglect, Mandatory reporting
Neglect

Failing to give the care and safety a resident needs, such as ignoring call lights, skipping meals, or leaving someone wet, cold, or in danger. It counts as mistreatment and must be reported.

Information a resident reports about how they feel, such as pain, dizziness, or nausea, which cannot be measured directly. The aide reports the resident's own words rather than interpreting them.

Related: Objective data, Documentation
Incident report

A factual form completed after an unexpected event such as a fall, injury, or error, describing what happened, when, and who was involved. It goes to the nurse and is a record for the facility, not a punishment tool.
