Ergonomics

Practical Example

Overview

Designing workspaces and tasks to fit the worker, reducing musculoskeletal injury risk. Tested on CNA and MA exams.

Resident care connections: Right to be free from restraints (physical and chemical) except for documented medical necessity. Right to voice grievances without fear of retaliation or discharge.

Exam Focus Areas

On the Cna Nnaap, Medical Assistant exam(s), questions about ergonomics typically test:

1. Resident rights and appropriate responses to violations
2. Body mechanics and safe transfer techniques
3. Observations that must be reported to the nurse immediately

Safety Considerations

Safe practice of ergonomics requires proper body mechanics and fall prevention:

• Tighten core muscles before lifting
• Wide base of support with feet shoulder-width apart, one foot slightly forward
• Use mechanical lifts for residents who cannot bear weight
• Push rather than pull when moving objects or residents
• Keep load close to body to reduce spinal strain

Key Values & Ranges

Designing workspaces and tasks to fit the worker, reducing musculoskeletal injury risk. Tested on CNA and MA exams.

Resident care connections: Right to be treated with dignity and respect at all times. Right to communicate freely with phone access, mail unopened, visitors at reasonable hours.

Calculation Methods

Understanding the numbers behind ergonomics is important for accurate assessment. Vital signs provide objective data: temperature (97.8-99.1 F oral), pulse (60-100 bpm), respirations (12-20/min), and blood pressure (under 120/80 normal). Report any values outside a resident's established baseline to the nurse immediately.
