Range of Motion (ROM)

The extent to which a joint can move in its normal directions. The nurse aide helps residents perform exercises, either active (the resident moves) or passive (the aide moves the limb), to keep joints flexible.

Related: Contracture, Repositioning
Contracture

A permanent shortening of muscle or tendon that locks a joint in a bent position, usually from lack of movement. Regular range-of-motion exercise and proper positioning help prevent it.

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

Damage to skin and underlying tissue caused by unrelieved pressure, often over bony areas such as the tailbone, heels, or hips. It starts as redness and can become an open wound if pressure is not relieved.

Related: Repositioning, Urinary Incontinence
Repositioning

Changing a resident's body position on a regular schedule, such as every two hours, to relieve pressure on bony areas. It is a key measure for preventing pressure injuries and maintaining comfort.

Related: Pressure Injury, Body Mechanics

Using correct posture, balance, and muscle strength when lifting or moving objects and people. Keeping the load close, bending the knees, and avoiding twisting protect both the aide and the resident from injury.

Related: Gait Belt, Repositioning
Gait Belt

A strong strap fastened around a resident's waist that gives the aide a secure hold while helping the person walk or transfer. It should be applied over clothing, never directly on bare skin.

Related: Body Mechanics, Orthostatic Hypotension

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

Aspiration

Breathing food, liquid, saliva, or vomit into the airway and lungs instead of swallowing it. It can cause choking or pneumonia, so residents with swallowing problems need careful positioning and feeding techniques.

Difficulty swallowing. Residents with dysphagia may cough or choke while eating, so the aide follows special instructions such as thickened liquids, small bites, and upright positioning during and after meals.

Washing the genital and anal area, always wiping from front to back to keep bacteria away from the urinary opening. It is done during bathing and after episodes of incontinence to prevent infection and skin breakdown.

Related: Urinary Incontinence, Standard Precautions
