Range of Motion (ROM)

The full movement a joint can make in its normal directions. Nurse aides help residents move each joint through its full range during exercises or care to keep muscles and joints working.

Related: Contracture, Body Mechanics
Contracture

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

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

Damage to skin and the tissue beneath it caused by constant pressure, often over a bony area such as the hip or heel. It starts as redness that does not fade and can become an open sore.

Related: Body Mechanics, Edema
Body Mechanics

The way a person holds and moves the body to stay balanced and avoid strain. Using good body mechanics means bending the knees, keeping the back straight, and holding loads close to the body.

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

Breathing food, liquid, saliva, or vomit into the airway and lungs instead of swallowing it. It can cause choking or serious lung infection, so residents who cough or choke while eating need slow, careful feeding.

Related: Dysphagia, NPO (Nothing by Mouth)
Dysphagia

Difficulty swallowing. A resident with dysphagia may cough, choke, drool, or pocket food in the cheek, and often needs thickened liquids, small bites, and an upright position while eating.

Related: Aspiration, NPO (Nothing by Mouth)
Intake and Output (I&O)

A record of how much fluid a resident drinks and how much leaves the body through urine, vomit, or drainage. Measuring intake and output helps the care team spot dehydration or fluid buildup.

Related: Edema, Indwelling Urinary Catheter
Indwelling Urinary Catheter

A tube placed through the urethra into the bladder to drain urine continuously into a bag. It raises the risk of infection, so the bag stays below the bladder and the tubing is kept from kinking.

Related: Intake and Output (I&O), Standard Precautions
Orthostatic Hypotension

A drop in blood pressure when a person stands up quickly, causing dizziness, blurring, or fainting. Nurse aides help prevent it by raising residents slowly and letting them sit before standing.

Related: Vital Signs, Body Mechanics
Fecal Impaction

A hard mass of dried stool stuck in the rectum that a person cannot push out. Signs include liquid stool leaking around the blockage, cramping, and no bowel movement for several days.

Edema

Swelling caused by extra fluid trapped in body tissues, usually in the feet, ankles, or hands. The skin over the area looks puffy and may stay dented after being pressed.

Related: Intake and Output (I&O), Pressure Injury
Standard Precautions

The basic infection-control steps used with every resident, whether or not illness is known. They include hand hygiene, gloves, gowns, masks, and eye protection when blood or body fluids may be present.

Related: Indwelling Urinary Catheter
Vital Signs

Measurements of body temperature, pulse, breathing rate, blood pressure, and often pain or oxygen level. Changes from a resident's normal range are reported to the nurse.

Related: Orthostatic Hypotension, Documentation
NPO (Nothing by Mouth)

A medical order meaning nothing by mouth, so the resident receives no food, water, ice, or oral medicine. Nurse aides still give mouth care and explain why eating and drinking are stopped.

Related: Dysphagia, Aspiration
Empathy

Understanding and sharing what another person feels without taking on the feeling as your own. It is shown by listening closely, naming the feeling, and responding with warmth rather than pity.

Related: Dementia, Delirium
Dementia

A slow, permanent decline in memory, thinking, and judgment that interferes with daily life. It is caused by brain disease, not normal aging, and residents need simple instructions and patience.

Related: Delirium, Sundowning
