Activities of Daily Living (ADLs)

Everyday self-care tasks a person performs to live independently, such as bathing, dressing, grooming, eating, toileting, and moving from place to place. Nurse aides often help residents with the ADLs they cannot complete alone.

Related: Range of Motion (ROM), Perineal Care
Range of Motion (ROM)

The normal amount of movement a joint can make in each direction. Aides perform range-of-motion exercises by gently moving a resident's limbs through the motion they still have, which keeps joints flexible.

Related: Contracture, Activities of Daily Living (ADLs)
Contracture

A permanent shortening of muscle or tendon that pulls a joint into a fixed, bent position. It develops when a limb stays still for long periods, so regular movement and careful positioning help prevent it.

Related: Range of Motion (ROM), Pressure Injury
Pressure Injury

Damage to skin and underlying tissue caused by unrelieved pressure, usually over bony areas such as the heels, hips, or tailbone. Repositioning, skin checks, and keeping skin clean and dry help prevent it.

Related: Contracture, Activities of Daily Living (ADLs)
Fowler's Position

A semi-sitting position in which the head of the bed is raised 45 to 60 degrees and the knees may be slightly bent. It helps with breathing, eating, and tube feedings.

Related: Logrolling, Pressure Injury
Logrolling

Moving a resident as a unit by turning the whole body at once while keeping the spine aligned. It is used after back or neck surgery and requires at least two helpers to protect the spine.

Related: Fowler's Position, Range of Motion (ROM)
Perineal Care

Cleaning the genital and anal area, always wiping from front to back so germs are not carried toward the urinary opening. It is done during bathing and after toileting or incontinence to prevent infection and skin breakdown.

Related: Hand Hygiene, Standard Precautions
Hand Hygiene

Cleaning hands with soap and water or an alcohol-based rub to remove germs. It is the single most effective way to prevent the spread of infection and is required before and after every resident contact.

Related: Standard Precautions, Chain of Infection, Personal Protective Equipment (PPE)
Standard Precautions

Infection control practices used with every resident, every time, because any person may carry germs. They include hand hygiene, gloves, gowns, masks, safe handling of sharps, and proper cleaning of shared equipment.

Related: Transmission-Based Precautions, Personal Protective Equipment (PPE), Hand Hygiene
Personal Protective Equipment (PPE)

Barrier items such as gloves, gowns, masks, and eye protection worn to keep germs from touching the aide's skin, clothing, or mucous membranes. PPE is removed carefully and discarded before leaving the room.

Related: Standard Precautions, Hand Hygiene
Chain of Infection

The six linked conditions needed for an infection to spread: a germ, a place to live, a way out, a way to travel, a way in, and a person who can be infected. Breaking any one link stops the spread.

Related: Hand Hygiene, Standard Precautions, Transmission-Based Precautions
Transmission-Based Precautions

Extra precautions used with residents known or suspected to have a contagious illness, based on how it spreads: contact, droplet, or airborne. They are used in addition to standard precautions and may include a private room and a sign on the door.

Related: Standard Precautions, Personal Protective Equipment (PPE), Chain of Infection
Restraint

Any device or method that limits a person's freedom of movement or access to their own body, such as a vest, wrist strap, or a bed rail used as a barrier. Restraints require a doctor's order and are used only as a last resort.

Related: Resident Rights, Mandatory Reporting
RACE

A memory aid for fire response: Rescue anyone in immediate danger, sound the Alarm, Confine the fire by closing doors, and Extinguish small fires or Evacuate. Aides should know their facility's fire plan and nearest exits.

Abdominal Thrusts

Quick inward and upward pushes just above the navel, used to clear a complete airway blockage in a conscious choking adult. The pushes force air up from the lungs to pop the object loose.

Vital Signs

Measurements that show how well the body is working: temperature, pulse, respirations, blood pressure, and often oxygen saturation and pain. Changes are reported promptly to the nurse.

Related: Radial Pulse, Blood Pressure, Respiration
Radial Pulse

The heartbeat felt by pressing two fingers on the thumb side of the wrist. It is counted for 30 seconds and multiplied by two, or for a full minute when the rhythm feels irregular.

Related: Vital Signs, Respiration
Blood Pressure

The force of blood against artery walls, recorded as two numbers: systolic, when the heart contracts, over diastolic, when the heart rests. It is measured with a cuff and reported right away if very high or very low.

Related: Vital Signs, Orthostatic Hypotension
Respiration

One complete breath in and one breath out. Aides count breaths for 30 seconds and multiply by two, and they avoid telling the resident, because being watched can change the breathing rate.

Related: Vital Signs, Pulse Oximetry
Pulse Oximetry

A painless test using a clip on the fingertip that estimates how much oxygen the blood is carrying, shown as a percentage. A low reading is reported to the nurse.

Related: Respiration, Vital Signs
Intake and Output (I&O)

A record of all fluids a resident drinks and receives and all fluids lost through urine, vomit, diarrhea, or drainage. Accurate measurement, usually in milliliters, helps the care team judge hydration.

Related: NPO, Vital Signs
NPO

A medical order meaning nothing by mouth, which includes no food, water, ice chips, or oral medications. The aide should remove water pitchers and gently remind the resident why they cannot eat or drink.

Related: Intake and Output (I&O), Informed Consent
Orthostatic Hypotension

A sudden drop in blood pressure when a person stands up, causing dizziness, blurred vision, or fainting. Aides help prevent it by raising residents slowly and letting them sit with legs dangling first.

Related: Blood Pressure, Vital Signs
Therapeutic Communication

A planned, purposeful way of talking with a resident that supports physical and emotional well-being. It uses open questions, restating, and silence, and it always puts the resident's needs first.

Related: Active Listening, Empathy, Nonverbal Communication
Active Listening

Fully focusing on what a resident says, including tone and body language, without interrupting or planning a reply. Facing the person, nodding, and repeating key points show that you are paying attention.

Related: Therapeutic Communication, Nonverbal Communication
Aphasia

Difficulty understanding or producing language caused by brain damage, often after a stroke. Thinking is usually intact, so aides should speak slowly, use simple words, and allow extra time for a response.

Related: Therapeutic Communication, Active Listening
Empathy

Understanding and sharing what another person is feeling without taking on their emotions yourself. Saying "that sounds hard" shows empathy, while false cheerfulness or "it could be worse" does not.

Related: Active Listening, Therapeutic Communication
Nonverbal Communication

Messages sent without words, such as facial expressions, posture, tone of voice, touch, and eye contact. Aides should match their words and body language so the resident feels safe and respected.

Related: Active Listening, Therapeutic Communication
Scope of Practice

The tasks and duties a nurse aide is legally allowed to perform under state law and facility policy. An aide must never do anything outside that scope and should ask the nurse when unsure.

Related: Delegation, Chain of Command
Delegation

The nurse's act of assigning a specific task to a nurse aide while keeping responsibility for the resident's overall care. The aide may accept or decline a task based on training and must report results back.

Related: Scope of Practice, Chain of Command
