Vital signs

Measurements of body temperature, pulse, respiration, and blood pressure, sometimes including pain and oxygen saturation. They show how well the body is working and are compared with the resident's own normal baseline.

Related: Blood pressure, Radial pulse, Respiration
Blood pressure

The force of blood pushing against the artery walls, recorded as two numbers: systolic, when the heart contracts, over diastolic, when it rests. Report a reading far above or below the resident's usual range.

Related: Radial pulse, Vital signs
Radial pulse

The number of heartbeats felt in one minute by pressing two fingers on the thumb side of the wrist. Note the rate, rhythm, and strength, and never use your own thumb.

Related: Respiration, Vital signs
Respiration

The number of breaths a resident takes in one minute, with one breath in and out counted as one. Count without telling the resident and note whether breathing is easy, noisy, shallow, or deep.

Related: Vital signs, Radial pulse
Intake and output

A record of all fluids a resident drinks and all fluids leaving the body, such as urine, vomit, and drainage, over a set period. Accurate measuring helps the nurse spot dehydration or fluid buildup.

Related: Catheter care
Hand hygiene

Washing hands with soap and water or rubbing them with alcohol-based sanitizer. It is the single best way to stop the spread of infection, so do it before and after every resident contact.

Related: Standard precautions, Personal protective equipment (PPE)
Standard precautions

Infection-control steps used with every resident every time, because any body fluid may carry germs. They include hand hygiene, gloves, gown, mask, and safe handling of soiled items and sharps.

Related: Hand hygiene, Personal protective equipment (PPE)
Personal protective equipment (PPE)

Gloves, gown, mask, and eye protection worn to keep germs from passing between you and a resident. Put it on before contact and take it off carefully before leaving the room.

Related: Hand hygiene, Standard precautions
Pressure injury

Damage to skin and underlying tissue caused by unrelieved pressure, usually over bony spots like the tailbone, heels, or hips. Check skin often, keep it clean and dry, and reposition residents regularly.

Related: Positioning, Range of motion
Catheter care

Cleaning the area where a urinary catheter enters the body and keeping the tubing and drainage bag below the bladder. This prevents pulling, kinks, and infection.

Related: Intake and output, Perineal care
Gait belt

A wide strap buckled around a resident's waist that gives the caregiver a firm hold during walking and transfers. It must fit snugly over clothing and is never used to tie anyone down.

Related: Ambulation
Bed bath

Washing a resident's body in bed with a basin, soap, and washcloths. Wash from cleanest to dirtiest areas, keep the person covered for privacy and warmth, and look for reddened or broken skin.

Related: Perineal care, Oral care
Perineal care

Washing the genital and anal area, always wiping from front to back, to prevent infection and odor. Wear gloves, use a fresh part of the cloth for each stroke, and offer it during bathing and after toileting.

Related: Bed bath, Catheter care
Oral care

Brushing teeth, gums, and tongue, or caring for dentures, to keep the mouth clean and comfortable. Give it at least twice a day and after meals, and look for sores or white patches.

Related: Denture care
Denture care

Cleaning false teeth over a basin lined with a towel or filled with water so they will not break if dropped. Use denture cleaner, rinse well, and store them in a labeled cup when not in the mouth.

Related: Oral care
Dressing

Helping a resident put on and remove clothing. Dress the weak or affected side first and undress that side last, and let the resident do as much as possible.

Related: Activities of daily living (ADLs), Positioning
Positioning

Placing a resident's body in a safe, comfortable alignment supported with pillows. Change position at least every two hours, or as ordered, to protect skin, breathing, and comfort.

Related: Pressure injury, Range of motion
Logrolling

Moving a resident as one unit while keeping the spine straight, usually with two helpers using a draw sheet. It is used after back or hip surgery and for anyone who must not twist.

Related: Positioning
Activities of daily living (ADLs)

The everyday tasks of bathing, dressing, eating, toileting, and moving around. CNAs help residents do these things for themselves as much as they can.

Related: Dressing, Restorative care
Empathy

Understanding what another person is feeling and letting them know you see their situation. It differs from sympathy because you feel with the person rather than feeling sorry for them.

Related: Active listening, Therapeutic communication
Active listening

Giving full attention to a speaker by facing them, making eye contact, nodding, and repeating back what you heard. It helps residents feel respected and prevents misunderstandings.

Related: Empathy, Therapeutic communication
Therapeutic communication

Using words, tone, and body language that help a resident feel safe and understood. Ask open questions, allow silence, be honest, and avoid arguing, judging, or giving false reassurance.

Related: Active listening, Validation therapy
Depression

A lasting sad or empty mood with loss of interest, appetite or sleep changes, and hopelessness. In older adults it may look like confusion or physical complaints, so report changes to the nurse.

Related: Empathy, Therapeutic communication
Cultural competence

Respecting and adjusting to a resident's culture, language, religion, and health beliefs. Ask about preferences instead of assuming, and use a trained interpreter when one is needed.

Related: Therapeutic communication
Dementia

A group of brain conditions, often caused by Alzheimer's disease, that slowly damage memory, thinking, and judgment. It is not a normal part of aging and gets worse over time.

Related: Sundowning, Wandering, Validation therapy
Sundowning

More confusion, restlessness, or agitation in the late afternoon and evening, which is common in dementia. Reduce noise and clutter, keep routines steady, and respond calmly.

Related: Dementia, Wandering
Wandering

Walking or moving about without a clear purpose, common in dementia and a serious safety risk. Do not argue or block the person roughly; redirect, offer an activity, and follow the safety plan.

Related: Sundowning, Dementia
Validation therapy

Accepting a confused resident's feelings and version of reality instead of correcting the facts. It lowers distress because the person feels heard rather than argued with.

Related: Dementia, Therapeutic communication
Aphasia

Trouble speaking or understanding language after brain damage such as a stroke. Speak slowly, use gestures and yes-or-no questions, and give plenty of time to answer.

Related: Therapeutic communication, Dementia
Contracture

A permanent tightening of muscle or tendon that freezes a joint in a bent position, often from lack of movement. Range of motion, good positioning, and splints help prevent it.

Related: Range of motion, Positioning
Range of motion

Moving a joint through its full normal pattern, either by the resident (active) or by the caregiver (passive). It keeps joints flexible and muscles working; stop if the resident has pain.

Related: Contracture, Restorative care
Ambulation

Walking, with or without a device or help. Encourage it daily, use a gait belt, and follow the care plan for how much support is safe.

Related: Gait belt, Restorative care

Care that helps a resident regain or keep function and independence after illness or injury. It includes exercise, practicing self-care, and using the techniques the therapy team teaches.

Related: Activities of daily living (ADLs), Range of motion
Bladder training

A toileting schedule that helps a resident regain bladder control. Offer the toilet at set times, praise success, and record results without scolding accidents.
