Which ergonomic principle should nurses know?

• A. Proper body mechanics, correct lifting techniques, and maintaining a safe workspace to prevent injury.
• B. Understanding pharmacology unrelated to safety.
• C. Scheduling patient appointments efficiently.
• D. Knowledge of dietary restrictions for patients.

Answer: (B)

Ergonomics and injury prevention in patient handling are the main ideas here. Nurses reduce the risk of back and body injuries by using proper body mechanics, correct lifting techniques, and a safe, prepared workspace.

When moving or repositioning a patient, keep the spine in a neutral position and bend at the hips and knees rather than at the waist. Hold the load close to the body to maintain your center of gravity, and avoid twisting or reaching. Use the strength of the legs, not the back, to lift or transfer. Plan the move, assess how heavy the load is, and enlist help or use assistive devices such as gait belts, transfer boards, or mechanical lifts. Prepare the environment: raise the bed and surfaces to a comfortable height, clear the path, and wear supportive, non-slip footwear. A quick, team-based approach with proper equipment and clear communication makes the transfer safer for both the nurse and the patient.

The other options focus on areas outside physical ergonomics—pharmacology, scheduling, and dietary knowledge. While those are important for overall patient care and safety, they don’t address preventing musculoskeletal injuries during patient handling.
