3.3 Safety and Injury Prevention

Fall Prevention and a Safe Environment

Falls are the most common accident among residents in long-term care, and fall prevention is one of the most heavily tested CNA safety topics. Most falls are preventable with simple measures:

• Keep the bed in the lowest position with the wheels locked.
• Keep the call light, water, and personal items within reach at all times.
• Answer call lights promptly — unanswered lights lead residents to get up alone and fall.
• Keep floors dry and clutter-free; clean spills immediately.
• Make sure the resident wears non-skid footwear and properly fitting clothing.
• Use adequate lighting, especially at night.

Always lock the wheels on beds, wheelchairs, and stretchers before transferring a resident — an unlocked wheel rolling away is a classic exam cause of injury. When you must leave a resident who is at risk, place the call light in reach and check on them frequently. A clean, organized environment with handrails and grab bars in hallways and bathrooms is a core part of the CNA's responsibility.

Restraints: Least-Restrictive Principle

A restraint is any device, garment, or barrier that restricts a resident's freedom of movement or normal access to their body. This includes obvious items like vest and wrist restraints, but also subtle ones: a tray table a resident cannot remove, a tucked-in sheet that pins them down, or a side rail used to keep them in bed. Federal OBRA (Omnibus Budget Reconciliation Act) law gives residents the right to be free from unnecessary restraints.

Rules tested on the exam:

1. A restraint requires a doctor's order stating the reason, type, and time limit.
2. Use the least restrictive method that protects the resident.
3. Restraints are used only after alternatives have failed.
4. Restraints are never used for staff convenience, discipline, or punishment.

Restraint alternatives the test rewards: increased supervision, bed/chair alarms, lowering the bed, placing the call light in reach, addressing the underlying need (toileting, pain, hunger), companionship, and activity or distraction.

Hazards of restraints include pressure injuries, reduced circulation, incontinence, muscle weakness, depression, strangulation, and even death. A restrained resident must be checked every 15 minutes, released at least every 2 hours for repositioning, toileting, food, fluids, and range-of-motion exercise. Tie a restraint with a quick-release knot to the movable part of the bed frame, never to a side rail.

Oxygen, Equipment, and Resident Identification

Oxygen Safety

Oxygen does not burn by itself but supports and speeds combustion, making any small flame far more dangerous. When oxygen is in use:

• Post "No Smoking — Oxygen in Use" signs and remove all smoking materials and lighters.
• Keep oxygen away from open flames, electric razors, candles, and matches, and from frayed cords or sparking devices.
• Avoid flammable products such as petroleum jelly, aerosol sprays, and alcohol-based items near the resident.
• Report low tank levels, kinked tubing, or a resident removing the cannula.

Equipment Safety

Inspect equipment before use. Report frayed electrical cords, loose parts, or malfunctioning lifts and beds, and remove broken items from service. Use mechanical lifts and assistive devices exactly as trained, and use good body mechanics to protect both you and the resident.

Identifying the Resident

Before any care, identify the resident. Check the ID band and compare the name (and often a second identifier such as date of birth) against your assignment or the care plan. Do not rely only on calling a name or on the room/bed number, because confused residents may answer to any name and may be in the wrong bed. Correct identification prevents giving care, a treatment, or a diet to the wrong person.

Wheelchair, Transfer, and General Accident Prevention

Many injuries happen during transfers and ambulation, so the exam expects safe technique. Before any transfer, lock the wheels of the bed and wheelchair, raise or remove the footrests so the resident does not trip, and use a gait/transfer belt when assisting an unsteady resident. Use good body mechanics — feet shoulder-width apart, bend at the knees, keep the load close, and lift with your legs, never your back — to protect yourself and the resident from injury.

Four broad categories of accidents are emphasized for CNAs:

Incident Reporting

Whenever an accident, fall, error, or injury occurs, an incident report is completed. Report the facts objectively — what you saw and did, the time, and the resident's condition — without guessing at causes or assigning blame. Reporting and documenting promptly protects the resident, supports follow-up care, and is a required part of the CNA's safety role tested on the California exam.

Side Rails and the Safety Data Sheet

Side rails deserve special attention because they can be either a safety aid or a restraint. A half rail may help a resident reposition and feel secure, but four raised rails that keep a resident from getting out of bed are considered a restraint and carry an entrapment and strangulation risk. Use rails only as ordered and as the care plan directs. Finally, every chemical on the unit has a Safety Data Sheet (SDS) describing its hazards and what to do for a spill or exposure; CNAs should know where these are kept so they can respond quickly and correctly to a chemical accident.
