Answer

Shared patient bathrooms equipped with UV disinfection robots

Answer

Increased staff-to-patient ratios without room changes

Answer

Air curtains at room entrances rather than door closures

Question 4

Which patient outcome is most strongly and directly improved by reducing hospital noise levels?

Accepted Answer

Sleep quality and duration

Answer

Wound healing rate

Answer

Medication adherence post-discharge

Answer

Surgical complication rates

Question 5

According to EBD research, which design element most effectively reduces nurse medication errors?

Accepted Answer

Dedicated, enclosed medication preparation rooms that minimize interruptions

Answer

Larger medication carts with color-coded drawers

Answer

Medication scanning stations located in patient corridors

Answer

Overhead display screens showing medication schedules

Question 6

How does patient room standardization improve safety outcomes in EBD practice?

Accepted Answer
