CEA CEA Ergonomics in Healthcare & Special Populations 1

Question 1

Which patient handling task poses the HIGHEST risk of low back injury for healthcare workers?

Accepted Answer

Bed-to-wheelchair lateral transfers

Answer

Lateral patient transfers require lifting and repositioning a dependent patient, generating high spinal compressive and shear forces on the caregiver.

Question 2

The Safe Patient Handling and Mobility (SPHM) approach recommends which primary intervention to reduce caregiver injuries?

Accepted Answer

Eliminating manual lifts through mechanical lift equipment and assistive devices

Answer

SPHM prioritizes engineering controls (ceiling lifts, transfer boards, sit-to-stand aids) over reliance on body mechanics training alone.

Question 3

Which anthropometric consideration is MOST critical when designing workstations for a diverse healthcare team that includes both male and female workers?

Accepted Answer

Designing for the 5th–95th percentile range with adjustability

Answer

Adjustable workstations that accommodate the 5th–95th percentile range ensure both small and large users can work without awkward postures.

Question 4

Prolonged standing on hard floors in surgical or assembly settings is MOST effectively mitigated by which intervention?

Accepted Answer

Anti-fatigue mats and footwear with cushioned insoles

Answer

Anti-fatigue mats reduce ground reaction force and promote micro-movements in leg muscles, decreasing discomfort and fatigue during prolonged standing.

Question 5

Needle stick injuries in healthcare are BEST prevented through which ergonomic/engineering control?

Accepted Answer

Safety-engineered sharps devices with passive or one-handed activation

Answer

Safety-engineered devices (retractable needles, needleless systems) are the highest-order control for preventing needle stick injuries.
